PC816, Phototransistor Output Optocoupler, DIP-4

The PC816 is a 1-channel optocoupler (also known as an optoisolator) that consists of an infrared light-emitting diode and a phototransistor in a compact DIP-4 package. It provides optical isolation between input and output signals, which makes it suitable for interfacing different voltage levels or isolating sensitive microcontroller inputs from higher-power circuits.

Key Features:

• High Isolation Voltage: 5000 Vrms input-to-output isolation.
• Wide CTR Range: Current Transfer Ratio (CTR) from 50% to 600% at I_F = 5 mA.
• Fast Response Time: Typical rise/fall times of 4–18 µs.
• High Collector-Emitter Voltage: V_CEO up to 70V.
• Compact DIP Package: 7.62 mm pin spacing for standard PCB layout.
• UL Recognized: Ensures reliability in industrial and consumer designs.

Additional Specifications:

• Package Type: DIP-4
• Collecter Emmiter Voltage Output (VCEO): 70V
• Maximum Collector Current (Ic): 50Ma
• Number of Channels: 1
• Mounting Style: Through Hole
• Isolation Voltage: 5000Vrms
• Forward Voltage (Vf): 1.2V
• Forward Current (If): 50Ma
