PS9634L-A

Overview

The PS9634L-A is an obsolete optoisolator designed as a power transistor driver, specifically for IGBT applications. It features a single channel with 5000Vrms voltage isolation and utilizes an 8-SMD Gull Wing package. The device exhibits a common mode transient immunity of at least 1kV/µs, with maximum propagation delays of 5µs for both low-to-high and high-to-low transitions.

Feature Summary

• Integrated optical linkage with GaAs infrared LED input and photodiode output
• High common mode transient immunity for robust noise rejection
• Optimized design for driving IGBT power transistors

Applications

• IGBT driver circuits
• Power transistor driving amplifiers
• Industrial motor control systems

Procurement Notes

Verify component status carefully as this part is listed as obsolete by major distributors. Confirm availability through secondary market suppliers or authorized stockists if sourcing is required. Ensure the specific suffix matches the required package type to avoid integration errors in existing designs.

Selection Notes

Select this component only for legacy system maintenance or replacement where the original design specified the PS9634L-A. Evaluate alternative modern isolators if new production is planned, considering updated availability and performance metrics. Verify pin compatibility before substitution.

Part Context

This device belongs to the CEL PS9634 family of special purpose isolators. It shares functional similarities with the PS9634 but differs in packaging, utilizing an SMD form factor compared to the DIP variant. The series is engineered for high-speed switching applications requiring galvanic isolation.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Consult manufacturer guidelines for end-of-life alternatives.
