TLP5702(D4-LF4,E

Logic Output Optoisolators Overview

The TLP5702(D4-LF4,E is a high-speed optically isolated gate driver manufactured by Toshiba Semiconductor and Storage. It integrates a Gallium Aluminum Arsenide (GaAlAs) infrared LED with a high-gain, high-speed photodetector IC chip. The device provides a push-pull output stage capable of driving IGBTs and MOSFETs directly. Key electrical specifications include a peak output current of 2.5A, a common-mode transient immunity (CMTI) of 20kV/µs, and an isolation voltage of 5000Vrms. It operates within a supply voltage range of 15V to 30V on the output side.

Logic Output Optoisolators Procurement Notes

Verify the specific suffix code against the manufacturer's latest datasheet to confirm pinout and packaging variations. Ensure compatibility with the target application's voltage levels and thermal requirements. Confirm RoHS compliance status if required by regulatory standards. Check for any recent product change notifications that may affect mechanical dimensions or material composition before finalizing procurement.

Logic Output Optoisolators Selection Notes

Select this component when high-speed switching and robust noise immunity are critical for the gate drive application. The integrated push-pull output reduces external component count compared to discrete solutions. Consider the 20kV/µs CMTI rating for applications with rapid voltage transients. Verify that the SO-6L package fits the available PCB space and thermal management strategy.
