TLP183(GB-TPL.E(T Présentation
An optocoupler (also called an opto-isolator or photocoupler) is a semiconductor device that transmits an electrical signal between two isolated circuits using a short optical transmission path through an optically transparent insulating barrier. The hierarchy is: optocoupler -> isolator -> solid-state relay family -> discrete semiconductor. Optocouplers are essential where ground loops, high-voltage transients, or safety isolation barriers must be crossed without a galvanic (conductive) path; the TLP183 family is widely used in industrial PLCs, communication interfaces, switch-mode power supply feedback loops, and I/O modules.
Key features include a forward current IF of 5 mA typical (low-input drive), a collector-emitter voltage VCEO of 80 V, a current transfer ratio (CTR) of 100-600% at IF=5 mA and VCE=5 V, and a response time tr/tr of approximately 4 microseconds. The 4-pin SO6 package is roughly one-third the footprint of a DIP-4 optocoupler, making this part well-suited to high-density surface-mount designs where a smaller isolation device is required.
The TLP183 employs a GaAs infrared LED (peak wavelength ~940 nm) bonded to a silicon NPN phototransistor in a reflective optical cavity. The high BVCEO rating of 80 V supports switching of higher-voltage rails than typical 30 V or 60 V optocouplers, and the low-input-current design reduces driver power consumption in MCU-driven interfaces.
Typical applications include PLC input modules, communication-interface signal isolation, switch-mode power supply (SMPS) feedback paths, programmable controller digital I/O, and AC adapter ground-loop isolation. The 3750 Vrms rating satisfies most reinforced-isolation requirements for industrial low-voltage control circuits.
When designing with this part, place at least 1 mm of creepage clearance around the package body to preserve the isolation rating; the SO6 outline requires it for 230 V AC mains-reinforced designs. A base-emitter resistor (~100 kΩ across B-E) on the phototransistor improves switching speed at the cost of slightly lower CTR.

Applications typiques
TLP183(GB-TPL.E(T convient pour 7 applications: PLC Digital Input Module Isolation, Switch-Mode Power Supply Feedback Path, Communication Interface Signal Isolation, Programmable Logic Controller Digital I/O, AC Adapter and SMPS Ground-Loop Isolation, Industrial Low-Voltage Safety Barrier Interface, Home Appliance and Office Machine Interface.
PLC Digital Input Module Isolation
Provides 3750 Vrms signal isolation between 24 V field-side inputs and the logic-side controller. The TLP183's GB-rank CTR of 100-600% at IF=5 mA supports reliable switching from a single current-limiting resistor, while its -55 to +125 °C range survives harsh industrial cabinet temperatures. Place the part between the field connector and the MCU GPIO with the LED biased through an external resistor, and the phototransistor collector pulled up to the logic supply. Compared to a DIP-4 alternative, the SO6 footprint allows high-density 32-channel input cards.
Recommandé
Switch-Mode Power Supply Feedback Path
Isolates the primary-side PWM controller error-amplifier feedback signal from the secondary-side output voltage divider. The TLP183's 80 V VCEO comfortably tolerates secondary-side transients, and the GB-rank CTR produces a stable 1:1 error transfer across the 3750 Vrms barrier, which is the standard isolation requirement for non-reinforced 12 V or 24 V DC output supplies. Insert the part between the TL431 reference and the primary-side opto-input pin, with base-emitter resistor sized for the loop bandwidth. The low 5 mA LED drive reduces standby power in 5 V standby rails.
Recommandé
Communication Interface Signal Isolation
Provides isolation for RS-232 / RS-485 / CAN bus transceiver lines crossing between functional sections with different ground potentials. The TLP183's 4 µs typical response time satisfies low-speed communication interfaces up to a few hundred kbaud; for higher data rates, a logic-output optocoupler like TLP2361 is preferable. Place the device between the bus transceiver and the line connector to break ground loops; the 3750 Vrms barrier is sufficient for industrial 24 V systems and many building-automation applications. The SO6 footprint eases routing on densely populated interface cards.
Recommandé
Programmable Logic Controller Digital I/O
Isolates MCU GPIO lines from 24 V field I/O in PLC systems. The TLP183's GB-rank CTR band (100-600%) supports direct drive from 3.3 V or 5 V MCU pins through a series resistor, eliminating the need for an external driver transistor. The wide -55 to +125 °C operating envelope tolerates the elevated ambient temperatures inside sealed industrial enclosures. Wire the LED anode to the MCU pin via a 330-680 Ω resistor, connect cathode to ground, and pull up the phototransistor collector to the logic supply with a 10 kΩ resistor. The 80 V VCEO permits use in 48 V or 60 V field rails.
Recommandé
AC Adapter and SMPS Ground-Loop Isolation
Breaks ground loops between the secondary side of an AC adapter or isolated DC-DC converter and the user-side system ground. The TLP183's 3750 Vrms rating is sufficient for adapters and converters supplied from a 230 V AC mains or 380 V DC distribution. The 50 mA collector current supports direct drive of subsequent interface logic, and the GB-rank CTR band minimizes supply current in standby. Place a single TLP183 in the housekeeping or feedback path; the SO6 4-pin package fits standard adapter daughter boards with minimal PCB real estate.
Recommandé
Industrial Low-Voltage Safety Barrier Interface
Used in certified industrial safety barriers where 3750 Vrms reinforced isolation is required between field wiring and the safe-area electronics. The TLP183 is well-suited to 24 V proximity-sensor interfaces, limit-switch signal conditioning, and other low-frequency switching signals. Maintain at least 1 mm of creepage clearance around the SO6 package to preserve the rated isolation; this is mandatory for compliance with IEC 62368-1 / IEC 61508 functional isolation distances. A base-emitter pull-down resistor of around 100 kΩ accelerates turn-off in safety-related response-time-critical circuits.
Recommandé
Home Appliance and Office Machine Interface
Provides low-cost isolation in white goods (washing machines, dishwashers, microwave oven control boards) and office machines (printers, copiers). The TLP183's compact SO6 footprint saves PCB space in space-constrained consumer control boards, and its wide CTR bin (100-600%) tolerates LED aging over the appliance lifetime. The 80 V VCEO supports use in appliance 24 V or 36 V motor-drive rails, and the -55 to +125 °C range covers all consumer-environment operating conditions. Use the part between triac-driver optocouplers and the MCU logic for individual button or sensor inputs.

Notes de conception
When laying out the 4-pin SO6 footprint, maintain at least 1 mm of creepage clearance around the package body. The 3750 Vrms isolation rating assumes adequate PCB isolation distances - placing low-voltage traces immediately adjacent to the package pins can compromise the rating in 230 V AC mains designs. For IEC 62368-1 reinforced isolation, follow the standard IPC-2221 clearance rules scaled by the comparative tracking index (CTI) of the PCB laminate.
Add a base-emitter resistor of approximately 100 kΩ across pins 3 and 4 of the phototransistor. This speeds up turn-off (the phototransistor's base-collector capacitance otherwise resists rapid switching) at the cost of a small CTR reduction. For circuits operating above 10 kHz, this resistor is mandatory; below 1 kHz it is optional. The uncommitted base pin can also be used as a low-speed analog input by biasing it with a few hundred kΩ to ground for gentle gain control.
Estimated thermal dissipation: at maximum forward current (IF=20 mA, VF=1.4 V) and full phototransistor saturation (VCEsat=0.2 V, IC=50 mA), the device dissipates roughly 10 mW on the LED side and 10 mW on the phototransistor side. Total self-heating is therefore negligible - well below the derating limit - so the SO6 package does not require any heatsinking. Operating temperature is dominated by ambient; the -55 to +125 °C rating directly sets the usable envelope.
Route the LED cathode return trace close to the package pin to minimize input-side ground bounce. The phototransistor-side emitter (pin 3) should tie directly to the local logic ground near the receiving IC; long emitter traces pick up switching noise and can cause false triggering. Keep the LED-side current-limiting resistor within 5 mm of pin 1 to ensure predictable LED drive current and prevent ringing in fast-pulse applications.
