TLP183(GB-TPLE(T 개요
An optocoupler (also called a photocoupler or opto-isolator) is a semiconductor device that transmits electrical signals between two isolated circuits using light. The architecture is LED -> dielectric isolation barrier -> photodetector, which converts input current into infrared photons that traverse an electrically-non-conductive polymer or air gap before being re-converted to a current on the output side. This provides galvanic isolation rated in volts (here 3750 Vrms), preventing high-voltage transients, ground loops, and common-mode noise from coupling between the primary and secondary circuits. Phototransistor-output optocouplers such as the TLP183 belong to the broader isolator/solid-state-relay family, sit hierarchically under transistors and optocouplers, and are commonly used to bridge low-voltage digital logic with industrial 24 V or 230 V AC domains.
Key features of the TLP183 include a collector-emitter breakdown voltage VCEO of 80 V (min), current transfer ratio (CTR) graded into GB/GR/H bins for design flexibility, an input forward current IF max of 50 mA, and a low typical forward voltage VF of approximately 1.25 V at 10 mA. The SO6 (4 effective pins) package provides a minimum creepage distance suitable for reinforced insulation in industrial control equipment, while the surface-mount form factor is significantly smaller than legacy DIP-4 optocouplers.
The TLP183 architecture uses a high-efficiency GaAs infrared LED emitter optically coupled to a silicon NPN phototransistor, with the GB CTR bin targeting the 100%-to-300% range at IF = 5 mA, VCE = 5 V. This makes the part well suited for low-input-current applications where the driving side has limited source current, such as microcontroller GPIO pins or battery-management interfaces. Compared with high-speed gate-driver optocouplers, the TLP183 is optimized for slower switching speeds (typical ton/tof in the microsecond range), trading bandwidth for robust CTR over temperature.
Typical applications include PLC digital input modules, communication-interface isolation, switched-mode power supply (SMPS) feedback loops, industrial sensor interfaces, and home appliance control boards. The part's wide -55 °C to +125 °C operating range and 3750 Vrms isolation rating also suit factory-automation equipment and renewable-energy inverter control sections.
When designing with the TLP183, ensure that the input-side current-limiting resistor is sized for the chosen CTR bin - a CTR of 100% at IF = 5 mA means the output transistor can sink approximately 5 mA at VCE = 5 V. Always observe maximum IF (50 mA) and power dissipation limits, and add a base-emitter resistor if slow turn-off is unacceptable in the target switching frequency.

일반적인 애플리케이션
TLP183(GB-TPLE(T 적합 용도: 6 애플리케이션s: PLC Digital Input Module Isolation, Communication Interface (RS-485/CAN) Isolation, Switched-Mode Power Supply (SMPS) Feedback, Industrial Sensor Signal Isolation, Home Appliance Control Board Isolation, Solar Inverter Control Interface.
PLC Digital Input Module Isolation
The TLP183's 3750 Vrms isolation and SO6 surface-mount footprint make it well suited for PLC digital input modules that must bridge 24 V field-side signals to low-voltage logic controllers. The GB CTR bin (100% minimum at IF = 5 mA) ensures reliable transfer of 24 V DC sensor inputs (typically current-limited to 5-10 mA) directly to a 3.3 V or 5 V GPIO pin on the PLC backplane MCU, with no ground-loop risk and reinforced insulation per IEC 61131-2. Compared with phototriac or AC-input optos, the DC-input TLP183 is optimal for DC switching applications where stable CTR over -25 to +70 °C industrial ambient is required.

Communication Interface (RS-485/CAN) Isolation
Industrial RS-485 and CAN bus transceivers require galvanic isolation to break ground loops between networked nodes; the TLP183 provides 3750 Vrms of reinforced insulation in the SO6 footprint. Its DC input is driven by the transceiver's fault/indicator output or a dedicated GPIO, while its phototransistor output feeds an interrupt or status LED driver on the isolated side. CTR of 100% to 300% at IF = 5 mA gives sufficient margin for low-current GPIO drive (3.3 V CMOS with 1 kΩ series resistor), and the wide -55 °C to +125 °C range covers outdoor cabinet deployments.
추천
Switched-Mode Power Supply (SMPS) Feedback
In isolated AC-DC and DC-DC converters, the TLP183 closes the primary-to-secondary feedback loop with 3750 Vrms isolation, transferring the TL431 reference error signal from the low-voltage secondary back to the PWM controller on the high-voltage primary. The GB CTR bin provides consistent 100%-to-300% transfer at IF = 5 mA so the TL431 bias network (typically 1-10 mA cathode current) drives the LED within its linear region. For sub-100 kHz flyback or forward converters, the TLP183's microsecond-scale switching speed is sufficient; for higher-frequency designs, a high-speed logic-output optocoupler is preferred.
추천
Industrial Sensor Signal Isolation
The TLP183 isolates 4-20 mA current loops, proximity sensors, and limit switches in factory-automation environments, where 3750 Vrms isolation prevents motor-drive switching transients from corrupting low-voltage PLC analog and digital inputs. The SO6 footprint saves PCB space versus legacy DIP-4 optos, supporting high-density I/O modules with 8 or 16 channels per card. CTR of 100% minimum at IF = 5 mA allows direct drive from 24 V proximity sensors through a 4.7 kΩ current-limit resistor, eliminating the need for input buffers.
추천
Home Appliance Control Board Isolation
White goods (washing machines, dishwashers, microwave ovens, induction cooktops) use the TLP183 to isolate low-voltage MCU logic from 230 V AC mains-driven triac or relay stages. The 3750 Vrms isolation satisfies IEC 60335 household appliance safety requirements for reinforced insulation between user-accessible controls and hazardous voltages. Surface-mount SO6 packaging supports automated SMT assembly at scale, reducing manufacturing cost versus through-hole DIP-4 alternatives.
추천
Solar Inverter Control Interface
String solar inverters use the TLP183 for control-board signal isolation between the high-voltage DC bus side (up to 1000 V) and the low-voltage MPPT and grid-monitoring logic. The 3750 Vrms isolation handles the DC bus transient voltage with margin, while the SO6 package fits the high-density control PCB typical of 3-10 kW residential inverters. CTR stability across -25 °C to +85 °C outdoor operating range ensures consistent feedback performance without re-calibration across seasons.

설계 노트
Estimated: at the SO6 package's typical 0.1-inch lead pitch, allocate at least 6 mm of clearance under and around the optocoupler body to satisfy 3750 Vrms reinforced-insulation creepage per IEC 60747-5-5. Do not route any copper traces, vias, or component pads beneath the optocoupler body - the input-side and output-side copper pours must remain separated by an unbroken isolation gap. Avoid silkscreen or solder-mask bridges across the isolation barrier.
CTR degrades substantially at high temperature and low collector current. The TLP183 GB bin guarantees 100% minimum at IF = 5 mA, VCE = 5 V, Ta = 25 °C; at +85 °C ambient CTR typically falls 30-40%. For designs that must operate reliably across -25 °C to +85 °C, derate IF by at least 1.5x and verify worst-case output current against the minimum downstream load requirement. Always include a base-emitter resistor (typically 1-10 MΩ) on the phototransistor to ensure fast turn-off - otherwise toff can extend into the millisecond range due to phototransistor base charge storage.
Estimated: input-side power dissipation is approximately VF × IF, so at IF = 10 mA the LED dissipates about 12.5 mW (VF ≈ 1.25 V). Output-side power is VCE × IC, where IC must be limited to (CTR × IF) for the chosen bin. With a 5 V pull-up and CTR × IF = 5 mA, the phototransistor dissipates roughly 25 mW in saturation. Total package dissipation of ~250 mW is well within the SO6 thermal envelope (estimated θJA ≈ 300 °C/W) - no heatsink required, but adequate copper pour on input and output pins improves reliability.
Place the input-side current-limiting resistor as close to the LED anode (pin 1) as possible to minimize noise pickup on the high-impedance LED forward-voltage node. Keep the output-side pull-up resistor close to pin 1 (collector) to minimize parasitic capacitance and improve switching speed. Avoid running digital signals parallel to the optocoupler's isolation barrier on adjacent layers; use ground planes or keep-out zones to preserve creepage.
