TLP127(KOSD-TPL,F)

Overview

The TLP127(KOSD-TPL,F) is a single-channel optocoupler manufactured by Toshiba Semiconductor and Storage. It integrates an infrared emitting diode with a Darlington phototransistor featuring an integrated base-emitter resistor. The device provides electrical isolation with a rated isolation voltage of 2500 Vrms. Key electrical parameters include a collector-emitter breakdown voltage (VCEO) of 300 V, a forward voltage (Vf) of approximately 1.15 V to 1.3 V, and a maximum DC forward current of 50 mA. The output can handle up to 150 mA, with a typical rise time of 40 µs and fall time of 15 µs under standard test conditions.

Feature Summary

Integrates a Darlington phototransistor with a built-in base-emitter resistor for high gain and simplified circuit design.
Provides robust electrical isolation between input and output circuits to ensure safety and noise immunity.
Features low leakage current characteristics suitable for sensitive signal transmission applications.

Applications

Programmable logic controllers
DC-output modules
Telecommunications equipment

Procurement Notes

Verify the specific suffix KOSD-TPL against the official Toshiba datasheet to confirm pinout compatibility and package dimensions. Ensure the component meets required environmental certifications such as RoHS compliance before integration into final assemblies.

Selection Notes

Select this component when high current transfer ratio is needed due to the Darlington configuration. The integrated resistor simplifies drive circuitry. Verify that the 300 V output voltage rating and 2500 Vrms isolation level meet the system's safety and operational requirements.

Part Context

This part belongs to Toshiba's small outline photocoupler series designed for surface mount assembly. It is engineered for compact PCB layouts while maintaining high reliability in industrial and commercial electronic systems requiring galvanic isolation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing requires independent verification of pinouts and electrical specifications with alternative manufacturers.

FAQ
