PC817X3YSZW

Transistor, Photovoltaic Output Optoisolators Overview

The PC817X3YSZW is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features an infrared emitting diode optically coupled to a phototransistor within a DIP-4 package. The device provides electrical isolation with a rated insulation voltage of 5000 Vrms. Key electrical parameters include a maximum collector-emitter voltage of 80 V, a maximum collector current of 8 mA, and a forward current rating of 50 mA. The typical rise and fall times are specified at 18 µs, supporting general-purpose signal isolation applications.

Transistor, Photovoltaic Output Optoisolators Feature Summary

• Provides high-voltage electrical isolation between input and output circuits using optical transmission.
• Integrates an infrared LED emitter with a silicon phototransistor for reliable signal coupling.
• Designed for through-hole mounting in standard four-pin dual in-line packages.

Transistor, Photovoltaic Output Optoisolators Applications

• Signal isolation in microprocessor control systems
• Switching power supply feedback loops
• Solid-state relay driver circuits

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'YSZW' against official Sharp datasheets to confirm pinout compatibility and packaging type. Ensure the component meets required insulation voltage ratings for the target application. Confirm availability status as distribution channels may indicate restricted supply or regional sales limitations.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when a standard single-channel transistor output optocoupler is required for basic isolation tasks. Consider the 80 V collector-emitter voltage limit and 8 mA current capacity for load requirements. Evaluate the 18 µs switching speed against system timing constraints before finalizing the design.

Transistor, Photovoltaic Output Optoisolators Part Context

This part belongs to the PC817 series of optocouplers, a widely used family of single-channel devices. The PC817 series is characterized by its compact DIP-4 form factor and general-purpose performance. Variations within the series typically differ by CTR ranges, switching speeds, or specific packaging configurations such as surface mount or through-hole variants.

Transistor, Photovoltaic Output Optoisolators Replacement Considerations

Compatible substitutes include other PC817 series variants from Sharp or equivalent transistor-output optocouplers from manufacturers like Vishay or Toshiba, provided they match the DIP-4 package, 5000 Vrms isolation, and similar electrical characteristics.
