TLP183(GR) Descripción general
A phototransistor optocoupler (also called a photocoupler or optoisolator) is a semiconductor isolation component that transfers electrical signals between two circuits using a light path, providing galvanic isolation while allowing signal or low-power control coupling. Within the broader hierarchy, it belongs to: optocoupler -> isolator -> signal conditioning component -> discrete semiconductor, commonly classified under isolators/solid-state relays. Phototransistor output types are the workhorse of low-speed digital isolation in industrial, PLC, and power-supply feedback paths.
Key features include 3750 Vrms minimum isolation voltage, 50% minimum CTR at IF=0.5 mA / VCE=5 V (GR bin grading), 80 V minimum VCEO, 6 V minimum VECO, 50 mA collector current capability, and 4 us typical switching speed. The SO6 footprint is significantly smaller than legacy DIP optocouplers, enabling high-density surface-mount designs on programmable controller and SMPS boards.
Internally, the TLP183(GR) uses a GaAs infrared LED die facing a silicon NPN phototransistor die across an optically transparent isolation barrier. The GR CTR bin narrows the transfer-ratio window to 100-300% at IF=5 mA, simplifying design-in when a known gain band is required versus the broader TLP183 base spec.
Typical applications include programmable logic controller (PLC) digital input isolation, switching power supply feedback loops, communication interface line receivers, and any high-density industrial control board needing logic-level signal isolation across a 3750 Vrms isolation barrier.
When designing with this part, observe the IF=0.5 mA low-input drive condition that defines the minimum CTR - derate IF to keep the LED within its absolute maximum ratings, and provide a 0.1 uF bypass cap across the output collector supply when used in noisy industrial environments.

Aplicaciones típicas
TLP183(GR) es adecuado para 6 aplicacións: PLC Digital Input Isolation, Switching Power Supply Feedback Isolation, Communication Interface Line Isolation, Industrial Sensor Signal Isolation, Medical Equipment Signal Isolation, Home Appliance Control Board Isolation.
PLC Digital Input Isolation
The TLP183(GR) is a natural fit for PLC digital input modules where 24V field signals must be isolated from 5V logic-side controllers across a reinforced isolation barrier. Its 3750 Vrms isolation rating satisfies IEC 61131-2 requirements for industrial control inputs, while the GR CTR bin (100-300% at IF=5 mA) provides predictable gain when driven from 24V field-side current-limiting resistors. The SO6 footprint is significantly smaller than legacy DIP optocouplers, enabling high-density 16- or 32-channel input cards. Place a 0.1 uF bypass capacitor across VCC on the logic side and a 10 kohm pull-up on the collector; switching speeds of 2 ms typically support input update rates up to 1 kHz, sufficient for digital input scanning.
Recomendado
Switching Power Supply Feedback Isolation
The TLP183(GR) is widely used in isolated AC-DC and DC-DC switching power supply feedback loops where the primary-side error amplifier signal must cross the isolation barrier to the secondary-side PWM controller. Its 3750 Vrms isolation, 80 V VCEO rating, and 50 mA collector current capability handle typical TL431-style feedback optocoupler circuits driving primary-side regulators. The GR CTR bin (100-300%) is the same grading scheme used by industry-standard feedback optocouplers like the PC817 series, simplifying cross-reference designs. The SO6 surface-mount package supports high-volume SMT manufacturing; recommended operation at IF=5-10 mA with VCE=1-5 V provides stable CTR for the opto-isolated feedback path.
Recomendado
Communication Interface Line Isolation
The TLP183(GR) provides signal isolation for RS-232, RS-485, and CAN bus transceivers where ground loops between connected devices create communication errors. Its 3750 Vrms isolation protects downstream logic from surges on field wiring, and the GR CTR bin (100-300% at IF=5 mA) enables direct interface to 3.3V or 5V UART logic with appropriate base resistor selection. The 2 us typical switching time supports baud rates up to 100 kbps, sufficient for most RS-232 and slow RS-485 links. The SO6 package reduces board area versus DIP optocouplers, critical for multi-port isolated interface modules. Pair with TVS diodes and common-mode chokes for robust EMC performance in industrial environments.
Recomendado
Industrial Sensor Signal Isolation
The TLP183(GR) isolates analog and digital sensor signals in industrial measurement equipment, including temperature, pressure, and flow sensors operating in harsh factory environments. Its 3750 Vrms isolation barrier protects sensitive ADC front-ends from common-mode voltages on field wiring, while the GR CTR bin (100-300%) enables direct interface to logic-level analog front ends. The -55C to +125C operating temperature range matches industrial environmental specs, and the SO6 package supports compact sensor transmitter designs. The 50 mA collector current capability also enables direct relay coil driver isolation when paired with a small signal BJT on the logic side.
Recomendado
Medical Equipment Signal Isolation
The TLP183(GR) provides patient-applied circuit isolation in medical monitoring equipment where IEC 60601-1 reinforced isolation is required between patient-connected sensors and host electronics. Its 3750 Vrms isolation rating provides adequate margin for patient isolation barriers in ECG, pulse oximeter, and blood pressure monitor designs. The GR CTR bin (100-300%) and SO6 footprint match the same miniaturization trends as the rest of the medical device industry. The 80 V VCEO rating protects against defibrillator pulse transients when combined with external TVS protection. Verify creepage and clearance distances for the specific medical safety standard required for the end application.
Recomendado
Home Appliance Control Board Isolation
The TLP183(GR) isolates microcontrollers from mains-connected relay and triac drivers in washing machines, refrigerators, air conditioners, and other white goods. Its 3750 Vrms isolation protects low-voltage logic from 110/220 VAC line transients, while the GR CTR bin enables direct drive from 3.3V or 5V MCU GPIO outputs through a series current-limiting resistor. The -55C to +125C operating temperature range supports appliance under-hood thermal environments, and the SO6 surface-mount package reduces manufacturing cost versus through-hole DIP optocouplers. Pair with a snubber network and TVS diode across the relay coil for robust surge immunity.

Notas de diseño
The TLP183(GR) specifies a 50% minimum CTR at IF=0.5 mA - this is a low-input drive condition designed for direct digital logic interface. Driving the LED at IF below 0.5 mA will not guarantee the 50% CTR floor. Recommended operating point is IF=5 mA where the GR bin guarantees 100-300% CTR. Also, never exceed the absolute maximum IF=50 mA or the device will suffer irreversible LED degradation. Add a series resistor calculated as (VCC - VF) / IF_desired, with VF typically 1.2-1.4V at IF=10 mA.
The TLP183(GR) SO6 package has a thermal resistance of approximately 200 C/W junction-to-ambient, which is acceptable for IF below 20 mA continuous. The LED junction temperature must stay below 125 C; at IF=20 mA and 1.4V VF, dissipation is 28 mW per channel, well within limits. When designing multi-channel isolated boards, maintain at least 5 mm spacing between adjacent optocouplers for thermal relief and to preserve isolation voltage creepage requirements. Operating in ambient temperatures above 85 C requires derating IF by 0.3 mA per degree C above 85 C.
Maintain minimum 5 mm creepage distance on PCB layout between the LED side (pins 1-2) and the phototransistor side (pins 3-6) of the SO6 footprint to preserve the 3750 Vrms isolation rating in pollution degree 2 environments. For reinforced isolation per IEC 60747-5-5, the SO6 package provides internal isolation but the PCB layout must complement it. Place a guard trace connected to an isolated ground between the input and output copper pours. Avoid running any high-voltage traces under the optocoupler body where they could reduce effective clearance.
