PC123X2YSZ1B

Overview

The PC123X2YSZ1B is a single-channel photovoltaic output optoisolator manufactured by SHARP/Socle Technology. It features a 4-DIP package with a 0.300-inch (7.62mm) width. The device provides an isolation voltage of 5000Vrms and operates within a temperature range of -30°C to +100°C. Key electrical characteristics include a minimum current transfer ratio of 50% at 5mA and a maximum of 400%. Propagation delays are specified at 3µs for turn-on and 4µs for turn-off.

Feature Summary

• Photovoltaic output configuration providing galvanic isolation
• High isolation voltage rating of 5000Vrms
• Wide operating temperature range from -30°C to +100°C
• Fast switching speeds with 3µs turn-on and 4µs turn-off times

Applications

• Industrial control systems requiring high isolation
• Signal transmission in noisy environments
• Power supply feedback loops
• Microcontroller interface circuits

Procurement Notes

Verify the specific suffix 'SZ1B' against official SHARP/Socle Technology documentation to ensure correct pinout and packaging specifications. Confirm that the 5000Vrms isolation rating meets your system's safety requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the 4-DIP package dimensions align with your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when high isolation voltage and fast response times are critical. The photovoltaic output type is suitable for applications requiring low leakage current. Consider the 4-DIP package size for board space limitations. Evaluate the -30°C to +100°C operating range against your environmental conditions. Compare propagation delays with other optoisolators if signal timing precision is a primary design constraint.

Part Context

This part belongs to the PC123 series of optoisolators from SHARP/Socle Technology, designed for general-purpose isolation applications. The series offers various output configurations and isolation voltages. The PC123X2YSZ1B specifically utilizes a transistor output structure within a standard DIP package, distinguishing it from higher-voltage variants like the PC123X5YFZ1B which features different isolation ratings.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with existing designs by comparing pinouts, isolation voltages, and electrical characteristics with alternative components from the same manufacturer or other suppliers.
