Overview
The PC123S is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features an NPN phototransistor output with a high current transfer ratio (CTR) ranging from 100% to 400% at a forward current of 5 mA. The device provides robust electrical isolation with a rated insulation voltage of 5000 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 50 mA, and a typical rise time of 4 µs and fall time of 3 µs. The component is housed in a standard 4-pin DIP package.
Feature Summary
- High current transfer ratio for efficient signal transmission
- Strong electrical isolation capability between input and output circuits
- Fast switching speed suitable for digital signal applications
Applications
- Industrial control systems requiring galvanic isolation
- Signal isolation in microprocessor interfaces
- Power supply feedback loops
Procurement Notes
Verify the obsolete status of this component before integration into new designs. Confirm availability through authorized distributors as stock levels fluctuate. Ensure compliance with RoHS directives if required by your specific application standards. Check for alternative lead times due to potential discontinuation.
Selection Notes
Select this component when high CTR and strong isolation are critical requirements. Consider the 4-DIP package constraints for PCB layout. Evaluate the 80 V collector-emitter voltage rating against circuit operating conditions. Verify that the switching speeds meet the system's timing requirements.
Part Context
This part belongs to Sharp Microelectronics' transistor output optocoupler family. It is designed for general-purpose isolation tasks. The series is known for reliability in industrial environments. Similar parts may offer different packaging or CTR ranges.
Replacement Considerations
Check for direct pin-compatible substitutes from Sharp or other manufacturers. Verify that replacement components match the 5000 Vrms isolation voltage and 80 V collector-emitter voltage ratings. Ensure the current transfer ratio falls within acceptable design margins.
