TLP182GB-TPL.E Visão geral
A photocoupler (also called an optoisolator) is a semiconductor device that transmits electrical signals between two isolated circuits using infrared light. Phototransistor-output optocouplers sit within the broader optocoupler family (which also includes triac, MOSFET, and Darlington outputs) and are commonly used for digital signal isolation in industrial control, switch-mode power supply feedback, and communication interfaces. The TLP182's AC-input design—achieved by antiparallel LED orientation—eliminates the need for input rectification, simplifying drive circuitry and reducing BOM count in PLC and AC-line-sensing applications.
Key specifications include 3750 Vrms isolation voltage (per UL/VDE standards), 50 mA collector current maximum, 80 V collector-emitter voltage, and a current transfer ratio (CTR) characteristic that varies with part grade. The TLP182 is supplied in seven CTR grades (e.g., GB rank denoting 100% to 600% CTR), allowing designers to optimize sensitivity and switching speed for specific load conditions. The wide -55°C to +125°C operating range supports harsh-environment deployment.
Architecturally, the TLP182 integrates a high-emitter-efficiency GaAlAs or GaAs LED pair with a silicon phototransistor receiver, isolated by a transparent silicone dielectric. The antiparallel LED arrangement accepts either polarity of AC input, while the phototransistor collector remains accessible as a single-ended output, simplifying biasing with a pull-up resistor to VCC.
Typical applications include programmable logic controller (PLC) digital input modules, switching-mode power supply feedback loops, communication interface isolation, AC line-voltage sensing, and hybrid IC interface boards. The SO6 footprint suits high-density SMT assembly and reflow soldering.
When designing with the TLP182, place a base-emitter resistor (typically 1-10 MΩ) across the phototransistor to reduce off-state leakage and improve switching speed. Ensure that the input LED drive current respects the absolute maximum ratings and that the supply voltage at the collector does not exceed VCEO. For switching-speed-sensitive designs, use a smaller pull-up resistor to accelerate the output rise time.

Aplicações típicas
TLP182GB-TPL.E é adequado para 7 aplicaçãos: PLC Digital Input Module, Switch-Mode Power Supply Feedback, Communication Interface Isolation, AC Line Voltage Sensing, Hybrid IC Interface, Industrial Sensor Interface Isolation, Solid-State Relay Driver Interface.
PLC Digital Input Module
The TLP182GB-TPL.E is well-suited to PLC digital input modules where AC or DC field signals must be isolated from the low-voltage controller logic. Its antiparallel LED input accepts 24 V AC or DC field signals directly, eliminating the input bridge rectifier and saving PCB area. With 3750 Vrms isolation the part meets the reinforced-insulation requirements typical of IEC 61131-2 PLC platforms. Switch time of a few microseconds supports scan cycles up to 10 kHz. Reference the Toshiba TLP182 datasheet typical application circuit (PLC input) for resistor selection.
Recomendado
Switch-Mode Power Supply Feedback
In isolated SMPS topologies such as flyback, forward, and quasi-resonant converters, the TLP182GB-TPL.E provides primary-to-secondary feedback isolation for the PWM controller. Its 3750 Vrms isolation meets typical safety requirements, while 80 V VCEO and 50 mA collector current are sufficient to drive TL431-equivalent feedback networks or optocoupler-input PWM controllers. Place the phototransistor collector pull-up close to the controller supply to minimize noise pickup. The part's -55°C to +125°C window supports industrial and outdoor SMPS designs.
Recomendado
Communication Interface Isolation
The TLP182GB-TPL.E isolates RS-232, RS-485, and CAN transceiver lines in industrial communication modules, breaking ground loops between networked devices. Its 3750 Vrms isolation satisfies common-mode voltage requirements on factory floors, while fast switching supports signaling rates up to several hundred kilobaud when biased appropriately. The SO6 footprint enables compact interface cards, and the AC-input feature eases bidirectional signaling. The -55°C to +125°C range suits outdoor and cabinet-mounted equipment.
Recomendado
AC Line Voltage Sensing
The TLP182GB-TPL.E's antiparallel LED architecture directly senses 100-240 V AC line transitions when paired with proper input current limiting, replacing discrete zero-cross detection circuits. The 3750 Vrms isolation creates a safe barrier between mains-voltage sensing and low-voltage control electronics in smart switches, dimmers, and appliance controllers. A base-emitter resistor of 1-10 MΩ across the phototransistor stabilizes off-state leakage and provides consistent switching thresholds across line frequencies.
Recomendado
Hybrid IC Interface
Hybrid IC modules that combine power devices, sensors, and signal-conditioning circuitry use the TLP182GB-TPL.E to bridge internal analog/digital sections. Its SO6 footprint is compatible with high-density hybrid assembly and reflow soldering. The 125°C upper temperature limit accommodates power-stage adjacent placement, while 3750 Vrms isolation allows co-packaging of line-connected and low-voltage signal paths in a single module. Reference the Toshiba TLP182 datasheet for hybrid IC application notes.
Recomendado
Industrial Sensor Interface Isolation
The TLP182GB-TPL.E isolates 4-20 mA current-loop sensor front-ends, thermocouple amplifiers, and other low-level analog signals in process instrumentation. Its low-saturation phototransistor and predictable CTR allow simple linearization of bias currents. Industrial automation systems benefit from its -55°C to +125°C operating window and 3750 Vrms isolation barrier against plant-side fault transients. Place a pull-up resistor sized for the desired bandwidth and follow the Toshiba datasheet biasing recommendations for sensor interfaces.
Recomendado
Solid-State Relay Driver Interface
In solid-state relay (SSR) modules driving AC loads, the TLP182GB-TPL.E provides the low-power control-side interface before the gate-drive stage of a TRIAC or MOSFET output. The AC-input option matches zero-cross trigger circuits in SSR modules that synchronize switching to the line. Its 3750 Vrms isolation rating exceeds the dielectric withstand requirements of most SSR safety certifications. Reference Toshiba application notes for SSR trigger circuit design with the TLP18x family.

Notas de projeto
Estimated: when selecting the input current limiting resistor, use the worst-case forward voltage of the LED pair (typically 1.2-1.4 V total for the antiparallel structure at 10-20 mA IF) and the minimum sourcing voltage. A 24 V AC-input PLC design with 10 mA LED current typically requires a series resistor around 2.0-2.2 kΩ rated for 0.5 W or more, accounting for peak line voltage. Failure to provide adequate headroom on the resistor causes LED current droop at low line voltage and unstable CTR behavior.
Maintain minimum creepage and clearance distances on the PCB between input and output sides of the TLP182GB-TPL.E to preserve the 3750 Vrms isolation rating. The 6-SOP package offers internal isolation but PCB layout determines the actual surge withstand. Avoid running input and output traces under the package or in close parallel; reserve at least 4 mm of clearance for typical reinforced-insulation applications per IEC 60747-5-5.
Add a base-emitter resistor (typically 1-10 MΩ) across the phototransistor of the TLP182GB-TPL.E to reduce off-state collector leakage to a few microamps and improve turn-off time. Without this resistor, leakage currents in the 100 nA range can produce false logic levels in high-impedance digital input designs. Place the resistor physically close to the emitter and collector pins to minimize parasitic capacitance across high-impedance nodes.
The TLP182GB-TPL.E is rated for 200 mW power dissipation and -55°C to +125°C operating range. In high-density designs where the part is adjacent to heat-generating components (e.g., power-stage MOSFETs), ensure that ambient temperature near the photoisolator stays below 85°C to maximize CTR retention. Provide copper pour on the output side for heat spreading, but maintain isolation clearance to the input side.
