PC3SD12YTZAF

Triac, SCR Output Optoisolators Overview

The PC3SD12YTZAF is a single-channel Triac output optocoupler manufactured by Sharp Microelectronics. It features a PhotoTriac output capable of handling a maximum RMS on-state current of 100 mA and a peak repetitive off-state voltage (VDRM) of 600 V. The device provides an isolation voltage of 5000 Vrms between the input LED and the output triac. Electrical characteristics include a maximum forward current of 50 mA, a typical forward voltage of 1.2 V, and a maximum trigger current of 10 mA. The unit operates within a temperature range of -30°C to +100°C and utilizes a 6-DIP through-hole package.
