Overview
The PC123Y23FZ9F is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features a DIP package and utilizes a phototransistor for signal transmission. The component is classified as obsolete (NRND), indicating it is not recommended for new designs. Key electrical characteristics include a maximum forward current of 50 mA, an isolation voltage of 5 kVrms, and a typical rise time of 4 µs. The device supports a maximum collector-emitter voltage of 80 V and operates within a temperature range of -40°C to +85°C.
Feature Summary
- Provides galvanic isolation between input and output circuits using a phototransistor configuration.
- Features reinforced insulation capabilities suitable for safety-critical applications.
- Designed for general-purpose digital signal transmission with standard switching speeds.
Applications
- Industrial control systems requiring circuit isolation
- Signal transmission in microprocessor interfaces
- Power supply feedback loops
Procurement Notes
Verify the NRND status before integration, as this component is not recommended for new designs. Confirm availability through authorized distributors, noting that stock may be limited or discontinued. Ensure compliance with RoHS directives if applicable to your region. Request updated lifecycle documentation from Sharp Microelectronics to assess long-term support viability.
Selection Notes
Select this component only for legacy system maintenance or replacement where form-factor compatibility is critical. Evaluate alternative modern optocouplers with similar pinouts and electrical ratings if designing new hardware. Consider the obsolescence status when planning production lifecycles. Verify that the 5 kVrms isolation rating meets specific safety standards required by the target application environment.
Part Context
This part belongs to Sharp's PC123 series of transistor output optocouplers. The series is designed for general-purpose isolation tasks. The specific suffix indicates packaging and tape/reel specifications. This family offers high reliability and is widely used in industrial and consumer electronics for signal coupling.
Replacement Considerations
PC123X1YIP0F: Similar DIP package and transistor output type; verify exact electrical parameter matches. PC817X2NSZW: Common alternative but requires checking isolation voltage and CTR differences against original specifications.
