TLP182(GR-TPL Visão geral
A photocoupler (also called an optocoupler or opto-isolator) is a semiconductor device that transmits electrical signals between two isolated circuits using light. The category hierarchy is optocoupler > isolator > signal conditioning IC > semiconductor. Phototransistor-output optocouplers provide galvanic isolation while preserving analog or digital signal integrity, and are widely used to protect low-voltage logic from high-voltage transients on industrial buses, motor drives, and switching power supply feedback paths. The TLP182's antiparallel LED configuration enables direct AC input operation without polarity constraints, simplifying half-wave and full-wave rectified control interfaces.
Key features of the TLP182 include 3750 Vrms isolation voltage, 50% minimum CTR at low IF = +/-0.5 mA (enabling high-efficiency LED drive), 80 V VCEO, and wide -55C to +125C operating range. The 4-lead SO6 package measures approximately 3.7 mm x 7.0 mm x 2.1 mm, providing high isolation in a compact footprint suitable for dense PCB layouts. The InGaAs infrared LED delivers faster switching characteristics compared with traditional GaAs emitters, supporting higher data rates in digital isolation applications.
The TLP182 uses a double-molded optical coupling path between the input LED stack and the output phototransistor, achieving reinforced insulation per industry standards. The antiparallel LED arrangement means the device conducts on either half-cycle of an AC input, eliminating the need for a rectifier bridge in low-frequency AC sensing circuits. The SO6 package provides 5.0 mm minimum external creepage and clearance distances, supporting 250 V working voltage per IEC 60747-5-5.
Typical applications include programmable logic controller (PLC) I/O modules, switching power supply feedback loops, AC line voltage sensing interfaces, communication interface isolation, hybrid IC signal transfer, and industrial control input modules. The wide temperature range and high CTR at low current make the TLP182 particularly well-suited for energy-efficient designs where LED drive current must be minimized.
When designing with the TLP182, observe proper creepage and clearance distances on the PCB and ensure input-side current-limiting resistors match the chosen IF (typically 5-20 mA). The base pin is internally connected only on selected variants - on the standard TLP182 the base is left open, and external bias should not be applied unless confirmed against the specific datasheet variant. Always derate CTR at elevated temperatures per the datasheet curves.

Aplicações típicas
TLP182(GR-TPL é adequado para 6 aplicaçãos: PLC Digital Input Module Isolation, Switching Power Supply Feedback Loop, AC Line Voltage Sensing Interface, Communication Interface Isolation (RS-485/RS-232), Hybrid IC Signal Transfer, Industrial Control Input Module.
PLC Digital Input Module Isolation
The TLP182's 3750 Vrms isolation and antiparallel LED configuration make it ideal for PLC digital input modules that must accept 24V AC or 100/120V AC field wiring without damage. The GR CTR rank delivers 100-300% current transfer at 5 mA IF, providing robust noise margins against industrial EMI on the field side. The -55C to +125C operating range supports outdoor and factory-floor cabinets without derating. Designed into 16- or 32-channel input cards, each TLP182 sits between an input conditioning network and the backplane logic, replacing electromechanical relays with a solid-state, surface-mount solution. The wide CTR margin ensures the output transistor saturates even at minimum IF, preventing false-zero states from grid transients. Designers can run the LED at lower current (2-3 mA) to reduce heat and extend reliability while still meeting worst-case CTR requirements across temperature.
Recomendado
Switching Power Supply Feedback Loop
The TLP182 isolates the primary-side PWM controller from the secondary-side feedback path in AC-DC and DC-DC switching power supplies, breaking the ground loop that causes instability. Its 80 V VCEO comfortably exceeds the 12V or 24V secondary rails typically used in feedback, while the 3750 Vrms isolation meets reinforced-insulation requirements for offline adapters. The AC-input LED configuration accepts either polarity, simplifying the optocoupler drive from a TL431 reference without polarity reversal. With GR-rank CTR of 100-300% at 5 mA, the TLP182 maintains tight loop bandwidth at minimum IF, preserving transient response. Used in 30-150W adapters and auxiliary supplies, the SO6 footprint keeps the secondary-side component count low and the PCB area compact. Designers should add a 100kHz base-to-emitter resistor across the phototransistor to damp AC switching noise that can otherwise inject ripple into the feedback loop.
Recomendado
AC Line Voltage Sensing Interface
The TLP182's two antiparallel InGaAs LEDs allow direct connection to 100/120/220/240V AC mains through a current-limiting resistor, eliminating the rectifier bridge traditionally required for DC-input optocouplers. This reduces BOM count and eliminates forward-voltage drop losses that bias low-current sensing. The 3750 Vrms isolation provides the safety barrier mandated for line-voltage crossing in IEC 60950 / IEC 62368 designs. The wide CTR spread of the GR rank (100-300%) accommodates mains-frequency variation (50/60 Hz) and component aging while maintaining reliable logic-level output. Used in smart-meter zero-cross detectors, dimmer feedback, and appliance line monitors, the TLP182 typically drives a logic gate or MCU interrupt input. The -55C to +125C rating supports outdoor meter housings and industrial enclosures with full operating margin.
Recomendado
Communication Interface Isolation (RS-485/RS-232)
The TLP182 provides galvanic isolation for half-duplex RS-485 or full-duplex RS-232 transceivers in industrial communication interfaces, breaking ground loops between networked equipment. Its 80 V VCEO handles the 5V transceiver rails, and the 3750 Vrms isolation survives the +/-15 kV ESD and 1 kV surge transients common on outdoor RS-485 cable runs. The AC-input LED lets designers drive the optocoupler directly from a UART waveform without DC restoration, simplifying the firmware and hardware. Used in PLC-to-inverter links, building-automation gateways, and isolated RS-485 repeaters, the TLP182 typically appears on the data line only - the bus power and direction control use dedicated digital isolators. The -55C to +125C operating range and 4-lead SO6 footprint enable compact, rugged interface cards suitable for DIN-rail mounting.
Recomendado
Hybrid IC Signal Transfer
The TLP182 enables signal transfer between separate domains in hybrid IC assemblies, such as between a high-voltage gate-driver section and a low-voltage control ASIC. Its 4-lead SO6 package is small enough to fit multiple isolators inside a single hybrid module, and its 3750 Vrms isolation eliminates the need for separate isolation transformers in lower-frequency control paths. Used in motor-drive hybrids, IGBT gate-driver modules, and industrial inverter power stages, the TLP182 typically carries fault signals, enable lines, or low-speed telemetry between isolated domains. The GR CTR rank of 100-300% at 5 mA IF delivers clean logic transfer with minimal LED current, preserving the hybrid's overall power budget. Designers should verify the 5 mm minimum creepage distance is preserved across the hybrid's internal PCB routing.
Recomendado
Industrial Control Input Module
The TLP182 is widely used in industrial digital input modules that sink or source 24V DC field signals and must present reinforced isolation to the backplane logic. The GR-rank CTR (100-300%) accommodates the 15-30V DC input range typical of IEC 61131-2 Type 1/3 digital inputs while maintaining saturated output. Its 80 V VCEO withstands field-wiring transients up to the typical TVS clamp level, and the 3750 Vrms isolation meets the 1500V Hi-Pot test commonly required for industrial certifications. The -55C to +125C operating range supports unheated cabinets in cold-climate installations. Used in modular I/O racks, remote I/O islands, and safety controllers, the TLP182 sits between the input protection network (resistor + TVS) and the backplane logic isolator or local MCU. Multiple TLP182 channels can share a common field-side supply without interaction, simplifying PCB layout.

Notas de projeto
Maintain at least 5.0 mm of creepage and clearance between input-side and output-side copper traces around the TLP182 SO6 package to preserve the 3750 Vrms isolation rating. Avoid routing any conductor, via, or solder pad beneath the optocoupler body, and do not place any component on the opposite PCB layer directly under the part. For reinforced insulation at 250V working voltage per IEC 60747-5-5, observe the minimum 8 mm through-air distance if the layout uses a slot or cutout between input and output sides.
Size the input-side current-limiting resistor for an LED forward current of 5-20 mA at the nominal input voltage. For 24V DC input with a minimum 1.4V total LED forward drop, a 2.2 kOhm resistor yields approximately 10 mA IF, comfortably within the GR-rank CTR test condition (5 mA) while leaving margin for supply variation. Add a parallel reverse-biased bypass diode (1N4148) across the input if the source can swing below ground, to protect the LED from reverse breakdown.
Estimated: at 10 mA IF and 1.4V VF, the input LED dissipates 14 mW; at VCE(sat) = 0.3V and 5 mA IC, the output transistor dissipates 1.5 mW - total package dissipation stays well below 100 mW and no heatsinking is required. However, derate CTR by 20-30% when operating continuously at 100C ambient per the Toshiba datasheet curves, and verify the output transistor saturates at worst-case IF and temperature for the application's logic-low threshold.
Do not connect anything to pin 6 (base) on the standard TLP182 unless the specific variant's datasheet confirms an internal base connection. Driving the base externally on the open-base variant can cause erratic switching or latch-up. Also, avoid driving the input from a high-impedance source without a series resistor - the LED is a current-driven device, not voltage-driven, and direct voltage drive without current limiting will destroy the junction. Finally, do not substitute a DC-input optocoupler (such as TLP292) into an AC-input design without adding a rectifier bridge, or the LED will conduct on only one half-cycle and miss every other event.
