TLP161J(IFT5,U,C,F

Triac, SCR Output Optoisolators Overview

The TLP161J(IFT5,U,C,F is a single-channel optoisolator manufactured by Toshiba Semiconductor and Storage. It integrates a gallium arsenide infrared-emitting diode with a photo-triac output in a compact surface-mount package. The device provides electrical isolation between input control circuits and high-voltage AC loads. Key specifications include a minimum peak off-state voltage of 600 V and an on-state current rating of 100 mA. The component supports zero-crossing detection to minimize electromagnetic interference during switching operations.
