Overview
The PC123YSJ000F is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features a DIP-4 package and provides an isolation voltage of 5000Vrms. The device utilizes an NPN phototransistor output with a typical collector-emitter saturation voltage of 1.2V. Key electrical parameters include a maximum forward current of 50mA, a minimum current transfer ratio of 100% at 5mA input, and a maximum CTR of 200% at the same condition. The component operates within a temperature range of -30°C to +100°C.
Feature Summary
- Provides high-voltage electrical isolation between input and output circuits using optical transmission.
- Features a standard four-pin dual in-line package suitable for through-hole mounting applications.
- Delivers high current transfer efficiency with specified gain characteristics for signal amplification.
Applications
- Industrial control systems requiring galvanic isolation
- Signal interface circuits in measurement equipment
- Power supply feedback loops
Procurement Notes
Verify the specific suffix SJ000F against official datasheets to confirm pinout and electrical tolerances. Ensure compatibility with existing PCB footprints and thermal management requirements. Confirm availability status as components may be subject to lifecycle changes or obsolescence notices from the manufacturer.
Selection Notes
Select this component when high isolation voltage and moderate speed are required. Compare current transfer ratio specifications against load requirements. Verify package dimensions and lead form against assembly constraints. Consider operating temperature range suitability for the intended environment.
Part Context
This part belongs to Sharp's general-purpose transistor output optocoupler family. These devices are designed for general signal isolation tasks. The series offers various packaging options and electrical ratings to suit different circuit density and performance needs.
Replacement Considerations
Check for direct replacements with identical pinouts and electrical ratings. Verify that substitute components meet the 5000Vrms isolation requirement and match the CTR specifications. Ensure thermal and mechanical compatibility before implementation.
