PC851XIJ000F

Overview

The PC851XIJ000F is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features an NPN phototransistor output with a maximum collector-emitter voltage of 350 V and a collector current of 4 mA. The device provides high isolation with a rated insulation voltage of 5000 Vrms. Electrical characteristics include a forward voltage of 1.4 V at 50 mA forward current, a reverse voltage of 6 V, and a power dissipation of 200 mW. Switching times are specified as 10 µs rise time and 12 µs fall time. The component operates within a temperature range of -25°C to +100°C and is available in surface-mount packaging.

Feature Summary

• High voltage isolation capability rated at 5000 Vrms for safe signal transmission between isolated circuits
• Wide collector-emitter voltage rating of 350 V allows operation in high-voltage switching applications
• Fast switching performance with defined rise and fall times suitable for digital signal isolation
• Compact surface-mount design facilitates integration into space-constrained electronic assemblies

Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops for voltage regulation
• Microcontroller interface circuits for level shifting and protection
• Solid-state relay driver circuits

Procurement Notes

Verify the specific suffix 'IJ' against the manufacturer's latest datasheet to confirm pinout configuration and package dimensions. Ensure compliance with RoHS directives if required by your assembly process. Cross-reference the part number with official Sharp Microelectronics documentation to validate availability and lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when high isolation voltage and wide collector-emitter voltage are critical requirements. The 350 V rating distinguishes it from standard 80 V or 3750 V variants in the PC series. Consider the 4 mA collector current limit for load driving capabilities. Verify that the 5000 Vrms insulation rating meets the safety standards of the target application environment.

Part Context

This part belongs to the Sharp PC851 series of transistor output optocouplers. It shares the core phototransistor technology with other variants but differs in specific electrical ratings and packaging. The series is designed for general-purpose isolation tasks where reliability and high voltage tolerance are prioritized over high-speed data transmission rates.

Replacement Considerations

Direct replacements must match the 350 V collector-emitter voltage and 5000 Vrms isolation rating. Generic PC851 variants may have lower voltage ratings (e.g., 80 V) and are not electrically equivalent. Verify pin compatibility and thermal characteristics before substituting with other manufacturers' high-voltage transistor output optocouplers.
