PC123Y22FZ0F

Overview

The PC123Y22FZ0F is a single-channel transistor output optocoupler from Sharp's PC123 series. It features an infrared emitting diode optically coupled to a phototransistor in a 4-pin DIP package. The device provides reinforced insulation with a maximum isolation voltage of 5 kVrms. It offers a current transfer ratio ranging from 50% to 400% at an input current of 5 mA. The component supports a maximum forward current of 50 mA and operates within a temperature range of -30°C to +100°C.

Feature Summary

• Reinforced insulation type with minimum isolation distance of 0.4 mm
• Double transfer mold package construction ideal for flow soldering
• High isolation voltage capability between input and output circuits
• Wide lead-spacing option available for extended creepage distance

Applications

• Input/output isolation for microcontroller units
• Noise suppression in switching circuits
• Signal transmission between circuits of different potentials
• Over-voltage detection systems

Procurement Notes

Verify the specific suffix against official Sharp documentation, as variations indicate differences in packaging or safety approvals. Confirm availability status as some series variants may be marked as not recommended for new designs. Ensure compliance with required regional safety standards such as UL or VDE before integration.

Selection Notes

Select this component when reinforced insulation and high isolation voltage are required for signal integrity. Consider the wide-lead spacing variant if extended creepage distance is necessary for safety clearance. Verify that the transistor output speed and current transfer ratio meet the specific circuit requirements for noise immunity and drive capability.

Part Context

This part belongs to the Sharp PC123 series, which includes various DIP and SMT options. The series is characterized by its use in applications requiring reliable electrical isolation. Other members include low-input current types and general-purpose variants, all sharing the core technology of an IRED coupled to a phototransistor.

Replacement Considerations

Direct substitutes within the same family include PC123X1YIP0F and PC123X1YSZ0F. These parts share similar electrical characteristics and package types but may differ in specific safety certifications or lead form configurations. Cross-referencing datasheets is essential to ensure functional compatibility.
