TLP127(KMC-TPL,F)

Overview

The TLP127(KMC-TPL,F) is a single-channel optocoupler featuring a gallium arsenide infrared LED and a Darlington phototransistor with an integrated base-emitter resistor. It provides high isolation voltage of 2500Vrms and a collector-emitter breakdown voltage of 300V. The device supports a maximum DC forward current of 50mA and offers a minimum current transfer ratio of 1000% at 1mA input. Output current capability reaches 150mA, with typical rise and fall times of 40µs and 15µs respectively. Operating temperature ranges from -55°C to 100°C.

Feature Summary

Integrates a GaAs infrared LED with a Darlington phototransistor for high gain output
Includes an internal base-emitter resistor to simplify circuit design and reduce component count
Provides robust electrical isolation suitable for safety-critical applications
Designed for surface mount assembly in compact small outline packages

Applications

Programmable logic controllers
DC-output modules
Telecommunication equipment

Procurement Notes

Verify the specific suffix KMC-TPL against official Toshiba documentation to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives and UL recognition standards required for end-product certification. Cross-reference datasheet revisions to confirm thermal characteristics and isolation ratings match system requirements before finalizing procurement orders.

Selection Notes

Select this component when high current transfer ratio and low cost are prioritized over switching speed. The integrated base resistor eliminates external biasing needs. Consider the relatively slow response time compared to logic gate outputs. Verify that the 300V collector-emitter voltage meets the load requirements. Ensure the SOP-4 footprint aligns with PCB layout constraints.

Part Context

This part belongs to Toshiba's mini flat coupler series designed for surface mount technology. It represents a standard solution for galvanic isolation in industrial control systems. The TLP127 family is widely recognized for its reliability in general-purpose isolation tasks where moderate speed and high gain are sufficient.
