PC123 Opto-Transistor - (AD1243)

Description:

The PC123 is a precision optocoupler in a DIP-4 package that integrates an infrared LED and a phototransistor into a single component. Ideal for applications requiring galvanic isolation between circuits.

Features:

• Input LED: 50mA forward current, 1A peak
• Withstands up to 6V reverse voltage
• Output Phototransistor: 70V maximum collector-emitter voltage
• Collector current: 50mA
• Power dissipation: 70mW (input) and 150mW (output)
• Reliable electrical isolation for industrial control systems, power supplies, and protection circuits
• Essential component for designs that demand secure signal transfer without direct connection between stages.
