PC942J00000F

Overview

The PC942J00000F is a special purpose isolator manufactured by Sharp Microelectronics, designed for high-voltage isolation applications. It features an infrared emitting diode optically coupled to an output phototransistor integrated circuit (OPIC). The device provides electrical isolation with a rated insulation voltage of 5000 Vrms. It is housed in an 8-pin dual in-line package (DIP) and supports surface mount gull-wing lead configurations. This component facilitates signal transmission across isolated barriers while maintaining high dielectric strength.

Feature Summary

• Integrates an infrared LED with an OPIC chip for efficient optical coupling
• Provides robust electrical isolation suitable for high-voltage environments
• Offers flexible packaging options including standard DIP and SMT gull-wing leads

Applications

• Power transistor driver circuits requiring galvanic isolation
• Industrial control systems needing high-voltage signal transmission
• General-purpose digital isolators in electronic interfaces

Procurement Notes

Verify the specific package variant required, as the PC942J00000F series includes both through-hole DIP and surface-mount gull-wing lead forms. Confirm that the selected form factor aligns with the target PCB layout and assembly process. Ensure compliance with RoHS directives if applicable to the manufacturing region. Cross-reference the manufacturer's latest documentation to confirm current production status and availability constraints before finalizing procurement plans.

Selection Notes

Select this component when high isolation voltage ratings are critical for system safety and noise immunity. The integration of the OPIC chip allows for compact design compared to discrete optocoupler solutions. Consider the available package types to match existing footprint requirements. Evaluate the thermal and electrical characteristics against the specific application's power dissipation and switching speed needs to ensure reliable long-term operation.

Part Context

This part belongs to Sharp Microelectronics' specialized isolator family, distinct from their standard transistor-output optocouplers like the PC3H or PC452 series. Unlike general-purpose photocouplers, the PC942J00000F is engineered specifically for driving power transistors and handling higher isolation voltages up to 5000 Vrms. It represents a dedicated solution for applications demanding robust barrier isolation within a compact 8-pin form factor.
