PC929 Optocoupler SMD IC
The PC929 Optocoupler SMD IC is a high‑performance single‑channel optical isolator designed for industrial inverter and power‑switching applications. This device integrates an input IRED (infrared emitting diode) coupled to an OPIC (optical integrated circuit) signal‑processing chip and incorporates a built‑in short‑circuit protection circuit
Features:
- Built-in IGBT shortcircuit protector circuit.
- Built-in direct drive circuit for IGBT with peak output current up to 0.4A.
- High-speed response with maximum propagation delay of 0.5µs.
- High isolation voltage of 4000Vrms.
- Half lead pin pitch of 1.27mm for compact SMD packaging.
