PC921 Optocoupler Dip-8 IC
The PC921 is a high-power OPIC (Optical Integrated Circuit) photocoupler designed for inverter control and general-purpose applications. Packaged in an 8-pin DIP format, it features an integrated light-emitting diode (LED) and photovoltaic output transistor with a built-in signal processing circuit. This device ensures high isolation between input and output sides with a typical isolation voltage of 5kVrms, making it suitable for safety-critical and noise-sensitive environments.
Features:
- Built-in base amplifier for direct power transistor drive.
- High output power with maximum continuous current of 0.5A DC.
- Fast response times with rise and fall under 2.0µs for pulse signals.
- High sensitivity with maximum low-to-high threshold current of 5mA.
