PC851XNNSZ0F

Transistor, Photovoltaic Output Optoisolators Overview

The PC851XNNSZ0F is a single-channel optoisolator manufactured by Sharp Microelectronics, featuring a phototransistor output. It provides an isolation voltage of 5000Vrms and supports a collector-emitter voltage of up to 350V. The device operates with a DC input and delivers a maximum output current of 50mA per channel. Key electrical characteristics include a typical forward voltage of 1.2V, a maximum DC forward current of 50mA, and a saturation voltage drop of 300mV. The minimum current transfer ratio is 40% at 5mA input. Response times are specified as 4µs for rise and 5µs for fall. It is housed in a 4-SMD鸥翼 (gull-wing) package and functions within a temperature range of -25°C to 100°C.

Transistor, Photovoltaic Output Optoisolators Procurement Notes

Verify the specific suffix 'NN' against official Sharp documentation to confirm pinout and insulation standards. Confirm availability status as distribution channels may list obsolete or end-of-life inventory. Ensure the selected variant matches the required 4-SMD gull-wing package dimensions for PCB layout compatibility. Cross-reference datasheet parameters for current transfer ratio and isolation voltage before finalizing procurement orders.

Transistor, Photovoltaic Output Optoisolators Selection Notes

Select this component when high collector-emitter voltage capability is required compared to standard low-voltage optocouplers. The 5000Vrms isolation rating suits applications demanding strict galvanic separation. Consider the 4-SMD package for automated assembly processes. Evaluate the 40% minimum CTR at 5mA to ensure adequate drive requirements for the downstream circuitry. Verify thermal operating limits align with the intended environment.
