PS9552-AX

Isolators - Gate Drivers Overview

The PS9552-AX is a single-channel transistor output optocoupler manufactured by CEL (California Eastern Laboratories), now part of Renesas Electronics. It features a GaAlAs LED input and an integrated photo diode, signal processing circuit, and power output transistor on one chip. The device provides 5000 Vrms isolation voltage and supports a maximum continuous output current of 2.5 A. It operates within a temperature range of -40°C to +100°C and is housed in an 8-pin DIP package.

Isolators - Gate Drivers Procurement Notes

Verify the manufacturer origin carefully, as production has transitioned from CEL to Renesas Electronics. Confirm the specific suffix (e.g., L1, L2, L3) if lead bending or creepage distance specifications are critical for your PCB layout. Ensure the component meets RoHS compliance requirements for your assembly process.

Isolators - Gate Drivers Selection Notes

Select this component when high output current capability up to 2.5 A is required for direct gate driving. Consider the 5000 Vrms isolation rating for safety-critical interfaces. Evaluate the need for specific lead configurations (L1/L2/L3 variants) based on creepage distance constraints in high-voltage designs.

Isolators - Gate Drivers Part Context

This component belongs to the PS9552 series of photocouplers designed specifically for high-performance gate driving applications. The series includes variants with different lead bending types to accommodate various insulation and creepage requirements while maintaining identical electrical characteristics for IGBT and MOSFET control.
