Overview
The PC123X5YFZ0F is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features an infrared emitting diode optically coupled to an NPN phototransistor within a 4-pin DIP package. The device provides reinforced insulation with a maximum isolation voltage of 5000 Vrms. It offers a current transfer ratio (CTR) ranging from 200% to 400% at an input current of 5 mA. Key electrical parameters include a collector-emitter breakdown voltage of 70 V minimum, a maximum forward current of 50 mA, and a typical rise time of 4 µs.
Feature Summary
- Provides high-speed signal transmission with typical rise and fall times of 4 µs and 3 µs respectively.
- Ensures safety through reinforced insulation capable of withstanding 5000 Vrms isolation voltage.
- Delivers high sensitivity via a wide current transfer ratio range of 200% to 400%.
- Features an NPN phototransistor output with a minimum collector-emitter breakdown voltage of 70 V.
Applications
- Industrial control systems requiring galvanic isolation
- Power supply feedback circuits
- Signal isolation in communication interfaces
Procurement Notes
This component is listed as obsolete or end-of-life by the manufacturer. Availability is limited to existing stock or third-party distributors. Verify RoHS compliance status and agency approvals such as UL and VDE before integration. Check for alternative sourcing options due to potential discontinuation risks.
Selection Notes
Select this part when high isolation voltage and moderate speed are required. The wide CTR range accommodates various input current conditions. Ensure the application operates within the specified temperature range of -30 °C to 100 °C. Consider the PDIP-4 package constraints for PCB layout.
Part Context
The PC123 series includes variants like PC123X1YIP0F and PC123X1YSZ0F, offering similar functionality with different packaging or CTR specifications. These components belong to Sharp's general-purpose transistor output optocoupler lineup designed for reliable signal transmission across isolated boundaries.
Replacement Considerations
Direct substitutes may include other Sharp models within the PC123 series or comparable transistor output optocouplers from other manufacturers meeting the 5kV isolation and 200-400% CTR requirements. Verify pinout compatibility and thermal characteristics.
