TLP351 Optocoupler IC – 8-Pin DIP

Product Description

The TLP351 is a high-speed optocoupler IC designed to provide electrical isolation between control and power circuits. It integrates a GaAlAs infrared LED on the input side and a high-speed photodetector with a logic-level output on the isolated side.

With its 8-pin DIP package, the TLP351 is well suited for driving power semiconductor devices such as IGBTs and MOSFETs, making it useful in switching power supplies, motor drives, inverters, and other power electronics applications.
