PC355MJ0000F

Overview

The PC355MJ0000F is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features a photodarlington output configuration housed in a 4-pin Mini-Flat surface-mount package. Key electrical specifications include a maximum collector-emitter voltage of 35 V, a maximum collector current of 16 mA, and an isolation voltage of 3750 Vrms. The device supports a maximum forward current of 50 mA with a typical forward voltage of 1.4 V. Operating temperature range spans from -30°C to +100°C, with a maximum power dissipation of 170 mW.

Feature Summary

• Photodarlington output structure provides high current transfer ratio for efficient signal transmission
• Mini-Flat SMD package enables compact board space utilization
• High isolation voltage capability ensures safe separation between input and output circuits

Applications

• General purpose digital signal isolation
• Microcontroller interface circuits
• Power supply feedback loops

Procurement Notes

Verify the specific suffix 'MJ' against official Sharp datasheets to confirm it denotes the tape and reel packaging variant rather than a different functional specification. Ensure compatibility with RoHS directives if required by your manufacturing standards. Cross-reference the part number with authorized distributors to confirm availability status, as some sources indicate this model may be obsolete or have limited stock.

Selection Notes

Select this component when a high current transfer ratio is required due to the photodarlington output type. It is suitable for applications needing moderate switching speeds and robust isolation. Compare against standard phototransistor variants if lower CTR is acceptable for cost reduction. Verify that the 35 V collector-emitter voltage rating meets the load requirements of the target circuit design.

Part Context

This part belongs to the Sharp PC355 series of optocouplers. It shares the same physical footprint and basic isolation characteristics as other variants in the family but differs in output stage technology. The MJ suffix typically indicates specific packaging or ranking criteria defined by the manufacturer. It serves as a discrete isolation component within broader electronic systems requiring galvanic separation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult Sharp Microelectronics technical support for direct replacements or equivalent alternatives from other manufacturers that match the 35V Vceo, 16mA Ico, and Mini-Flat package constraints.
