TLP127(F)

Overview

The TLP127(F) is a single-channel optocoupler featuring an infrared LED input and a Darlington phototransistor output. It provides high current transfer ratio performance with a collector-emitter voltage of 300V and isolation voltage of 2500Vrms. The device operates within a temperature range of -55°C to +100°C, dissipating up to 200mW. Key electrical parameters include a forward voltage of 1.3V max, rise time of 40µs, and fall time of 15µs at specified test conditions.

Feature Summary

Integrates an infrared LED with a Darlington phototransistor for high gain
Provides robust electrical isolation between input and output circuits
Features low leakage current and low clamp voltage characteristics

Applications

Programmable logic controllers
DC-output modules
Telecommunications equipment

Procurement Notes

Verify the specific suffix (TPL, U, or F) against the datasheet to confirm package type and tape/reel specifications. Ensure compliance with RoHS directives and UL recognition requirements for the target application environment. Confirm lead times and availability through authorized distributors.

Selection Notes

Select this component for applications requiring high current transfer ratio and strong isolation capabilities. Consider the slow switching speed suitable for general-purpose digital signal transmission rather than high-frequency data links. Evaluate thermal management needs given the 200mW power dissipation limit in surface mount configurations.

Part Context

This part belongs to Toshiba's Miniflat Coupler series designed for surface mount assembly. It utilizes a plastic SOP-6 package to provide compact isolation solutions. The series is engineered for reliability in industrial and communication systems where galvanic isolation is critical for safety and noise immunity.
