Sharp PC923L 0.6A Gate Driver Optocoupler

Sharp PC923L Single‑Channel OPIC™ Gate‑Drive Photocoupler – 5kV Isolation, IGBT/MOSFET Output

The PC923L is a high-speed, single-channel OPIC™ phototransistor optocoupler from Sharp. It features a built-in direct-drive circuit capable of delivering up to 0.6 A peak for driving MOSFETs or IGBTs, eliminating external drivers.

This device supports isolation voltage of 5000 V RMS between input and output. It offers fast switching with maximum propagation delay times of 0.5 µs (tPLH and tPHL). It also has excellent noise immunity with a minimum common-mode rejection rate of ±15 kV/µs.

Housed in an 8-pin DIP package (double transfer mold), it supports both through-hole and gull‑wing SMT variants. The device handles a wide operating voltage range (VCC = 15–30 V) with low supply current (~1.3 mA) and is UL1577 recognized. VDE0884 option is also available.

Designed for inverter control and industrial power electronics, the PC923L is ideal for gate driving in motor drives, air conditioners, electric cooktops, and other IGBT applications requiring fast, reliable gate isolation.
