PS9331L2-E3-AX

Isolators - Gate Drivers Overview

The PS9331L2-E3-AX is a high-speed optical coupler manufactured by CEL, classified as a gate driver isolator. It features a single channel with an input GaAlAs LED and an output comprising a photodiode, signal processing circuit, and power MOSFET. The device utilizes a 6-SDIP Gull Wing surface mount package designed for long creepage distance of at least 8 mm. Key electrical parameters include a data rate of 10 Mb/s, isolation voltage of 5000 Vrms, and forward current of 10 mA. Operating temperature range spans from -40°C to +85°C.

Isolators - Gate Drivers Feature Summary

• Integrated gate driver output stage combining photodiode, signal processing, and power MOSFET for direct IGBT/MOSFET drive
• High common-mode rejection ratio of +/-50kV/us for noise immunity in switching applications
• Extended creepage distance of 8mm minimum via gull-wing SMD package design
• Low propagation delay characteristics suitable for high-speed digital isolation

Isolators - Gate Drivers Applications

• Insulated Gate Bipolar Transistor (IGBT) gate driving
• Power MOSFET gate driving
• Industrial inverters and motor drives
• Switching power supplies requiring galvanic isolation

Isolators - Gate Drivers Procurement Notes

Verify the manufacturer designation carefully, as this component has been associated with both CEL and Renesas Electronics in various distribution channels due to corporate acquisitions. Confirm the specific suffix E3 indicates lead-free compliance if required by your assembly process. Check current availability status as supply chain variations exist between original manufacturers and distributors. Ensure the gull-wing package variant matches your PCB footprint requirements strictly.

Isolators - Gate Drivers Selection Notes

Select this component when high-speed isolation combined with direct gate drive capability is required. The integrated power output stage simplifies design compared to standard optocouplers needing external transistors. Consider the 8mm creepage distance for high-voltage isolation safety standards. Evaluate the 5000 Vrms isolation rating against system insulation requirements. Compare propagation delays with other high-speed isolators if timing precision is critical.

Isolators - Gate Drivers Part Context

This part belongs to the PS9331L series of optical coupled isolators. The L2 suffix specifically denotes the gull-wing package variant optimized for longer creepage distances compared to standard flat packages. The series integrates signal processing circuits to ensure fast switching times and high noise immunity, distinguishing it from basic phototransistor optocouplers.

Isolators - Gate Drivers Replacement Considerations

PS9332L2-E3-AX offers similar functionality but with a Photodarlington output instead of a MOSFET gate driver, resulting in different drive capabilities and speed characteristics.
