PC357N3J000F

Transistor, Photovoltaic Output Optoisolators Overview

The PC357N3J000F is a surface-mount transistor output optocoupler from the Sharp PC357NJ0000F series, housed in a 4-pin Mini-flat package. It features an infrared emitting diode optically coupled to a phototransistor with a 3.75kVrms isolation voltage and UL1577 recognition. The device operates within a temperature range of -30°C to 100°C. Key electrical parameters include a maximum collector-emitter voltage of 80V, a typical forward voltage of 1.2V, and a maximum DC forward current of 50mA. The current transfer ratio (CTR) is ranked between 200% and 400% at an input current of 5mA.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• High-speed switching capability with typical rise and fall times of 4µs and 3µs respectively
• Compact 4-pin Mini-flat surface mount package design for space-constrained applications
• Wide operating temperature range supporting industrial environments from -30°C to 100°C

Transistor, Photovoltaic Output Optoisolators Applications

• General purpose signal isolation in industrial control systems
• Interface circuits for microprocessors and logic devices
• Power supply feedback loops requiring galvanic isolation

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific CTR ranking suffix '3' corresponds to the required 200-400% gain band during procurement. Confirm the Mini-flat package dimensions match the target PCB footprint. Ensure compliance with RoHS and REACH regulations as specified in the datasheet. Cross-reference the manufacturer part number with distributor codes to avoid ordering errors.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a compact SMT optocoupler with high speed and moderate CTR is needed. The 200-400% CTR ranking provides sufficient gain for standard logic interfaces without excessive input current. Consider the 80V collector-emitter voltage limit for output circuit design. The Mini-flat package offers a smaller footprint compared to traditional DIP packages while maintaining similar isolation performance.

Transistor, Photovoltaic Output Optoisolators Part Context

The PC357N3J000F belongs to the broader PC357NJ0000F family of general-purpose photocouplers. This series includes variants with different CTR rankings and packaging options. The Mini-flat package distinguishes it from larger DIP or flat-pack alternatives within the same functional category. It serves as a modern replacement for older through-hole technologies in consumer and industrial electronics.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Compatible substitutes within the PC357NJ0000F series include PC357N1J000F and PC357N2J000F, which share identical pinouts and mechanical dimensions but differ in CTR rankings. Verify that alternative parts meet the specific 200-400% CTR requirement if signal integrity depends on precise gain characteristics.
