Key Features
- 80 V collector-emitter breakdown voltage enables isolation across 48 V and 60 V logic and power supply boundaries
- 100% minimum current transfer ratio (CTR) ensures reliable transistor saturation with low LED drive current at 50 mA max IF
- UL-approved isolation meets safety certification requirements for industrial control and home appliance designs
- 80 nA maximum dark current ensures clean logic output with minimal leakage in high-impedance phototransistor circuits
Applications
The TLP183(GR-TPL,E is used for galvanic signal isolation in industrial control systems, PLC I/O modules, and switching power supply feedback loops where logic signals must cross between ground-referenced and isolated domains at up to 80 V. Its 100% CTR and low forward voltage of 1.4 V maximum make it suitable for microcontroller-to-relay driver interfaces and motor drive enable signal isolation. Home appliances, HVAC controllers, and safety-certified equipment benefit from its UL-approved isolation construction.

Frequently Asked Questions
What collector-emitter voltage and current transfer ratio does the TLP183(GR-TPL,E support?
The TLP183(GR-TPL,E has an 80 V minimum collector-emitter breakdown voltage and a minimum current transfer ratio (CTR) of 100%, meaning the output collector current is at least equal to the LED input current. With a 50 mA maximum forward LED current and 1.4 V maximum forward voltage, the device can drive phototransistor outputs in isolation circuits for 48 V and 60 V industrial bus applications.
For PLC digital input modules isolating 24 V field signals, how does TLP183(GR-TPL,E's 80 V BVCEO rating provide design margin?
A 24 V field input signal with typical transient overvoltages can momentarily reach 40 V to 60 V. The TLP183(GR-TPL,E's 80 V BVCEO provides more than 2× margin above the 24 V nominal level and at least 33% margin above 60 V transients, ensuring the phototransistor output stage does not enter breakdown during ESD or inductive switching events common in PLC field wiring environments.
How does the TLP183(GR-TPL,E's 80 nA dark current specification affect digital logic output design?
With a maximum dark current of 80 nA flowing through the phototransistor collector when the LED is off, the TLP183(GR-TPL,E introduces minimal leakage into the output logic network. For a 10 kΩ pull-up resistor, 80 nA of leakage creates only 0.8 mV of false output voltage—well below the 0.8 V logic-low threshold of 3.3 V CMOS receivers—ensuring a clean logic-low when the input LED is not driven.
When should TLP183(GR-TPL,E be selected over a higher-speed optocoupler in feedback loop isolation for switching power supplies?
In switching power supply feedback loops where the error amplifier bandwidth is limited to 10 kHz to 50 kHz, the TLP183(GR-TPL,E's phototransistor CTR stability and 80 V isolation voltage are the dominant selection criteria rather than propagation delay. Choosing a faster but more expensive high-speed optocoupler provides no practical benefit when the control loop bandwidth is below 100 kHz, making the TLP183(GR-TPL,E a cost-effective choice for flyback and forward converter feedback isolation.
