PC3ST11NSZAF

Triac, SCR Output Optoisolators Overview

The PC3ST11NSZAF is a high-speed, low-power optocoupler manufactured by Sharp Microelectronics. It integrates an infrared emitting diode with a high-gain phototransistor output in a compact SMD package. The device offers a high Common Mode Transient Immunity (CMTI) of 50 kV/µs, ensuring reliable signal transmission in noisy environments. Key electrical parameters include a collector-emitter voltage (VCEO) of 80 V and a collector current (IC) of 50 mA. The unit operates within a temperature range of -40°C to +100°C and features a propagation delay of typically 2.5 µs for turn-on and 2.5 µs for turn-off.
