Sharp PC929 OPIC Optocoupler 4000V Isolation

Sharp PC929 OPIC Optocoupler 4000V Isolation

The PC929 is a Sharp Optical IC (OPIC™) phototransistor output optocoupler featuring an integrated IGBT short-circuit protection circuit. Designed for inverter gate drive applications, it includes a direct-drive output stage capable of delivering up to 400 mA peak for MOSFET or IGBT control.

PC929 provides high isolation voltage up to 4 kV RMS, with ultra-fast response times of max 500 ns for rising and falling edges. Packaged in a compact 14-pin mini-flat half-pitch SOIC, it meets UL1577 and optional VDE0884 approvals for safety-critical installations, and is optimized for SMT reflow soldering.

Ideal for integration in inverter drives, power converters, and industrial motor control circuits, the PC929 supports reliable overcurrent protection and enhanced gate switching performance in harsh environments.
