PC921 Optocoupler Dip-8 IC

Description

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. Specifications: Parameter Value Forward Current (IF) 25mA Reverse Voltage (VR) 6V Supply Voltage (Vcc) 35V Output Voltage (Vo) 35V Output Current (Io) 0.5A Peak Output Current (Iop) 2.0A Output Power Dissipation (Po) 500mW Total Power Dissipation (Ptot) 550mW Isolation Voltage (Viso) 5000Vrms Operating Temperature Range -20°Cto+80°C Storage Temperature Range -55°Cto+125°C Forward Voltage (VF) 1.1Vto1.75V Low→High Threshold Input Current (IFLH) 5mA Propagation Delay Time (tPLH/tPHL) 2.0µs Rise Time (tr) 2.0µs Fall Time (tf) 2.0µs Pin Configuration: Applications: Inverter-controlled air conditioners for motor drive. Low-capacitance general-purpose inverter systems. Power transistor base drive in control circuits. Package Include: 1x PC921 Optocoupler Dip-8 IC Datasheet: PC921
