PC123XNYIP0F

Overview

The PC123XNYIP0F is a single-channel transistor output optocoupler manufactured by Sharp Microelectronics. It features an SMD-4 surface mount package and provides 5000 Vrms isolation voltage between input and output circuits. The device utilizes an NPN phototransistor for signal transmission, supporting a maximum forward current of 50 mA with a typical forward voltage of 1.4 V. Key electrical characteristics include a collector-emitter saturation voltage of 1 V and a collector current capacity of 16 mA. The unit offers a minimum current transfer ratio of 50% and a maximum of 400%, with typical rise and fall times of 4 µs and 3 µs respectively.

Feature Summary

• Provides high-voltage galvanic isolation for signal integrity in sensitive circuits

Procurement Notes

Verify the specific suffix configuration against the manufacturer's latest datasheet to ensure compatibility with required isolation ratings and pinout definitions. Confirm RoHS compliance status and lead time availability directly with authorized distributors, as component variants may differ in packaging or environmental certifications. Cross-reference the part number with official Sharp documentation to validate functional specifications before procurement.

Selection Notes

Select this component when high isolation voltage is required in a small form factor. Ensure the circuit design accommodates the specified current transfer ratio range and switching speeds. Verify that the SMD-4 package dimensions fit the PCB layout constraints. Consider the thermal dissipation requirements relative to the maximum forward current limits during continuous operation.
