PS9552L1-AX

Isolators - Gate Drivers Overview

The PS9552L1-AX is a high-speed logic output optocoupler manufactured by CEL, part of the PS9552 series. It integrates a GaAlAs LED input with a photo diode, signal processing circuit, and power output transistor on a single chip. Key electrical parameters include a maximum continuous output current of 2.5 A, an isolation voltage of 5000 Vrms, and a propagation delay of 0.5 us. The device features rise and fall times of 0.1 us each. It operates within a temperature range of -40 C to +100 C, dissipates up to 300 mW, and utilizes a DIP-8 through-hole package.

• High-speed signal isolation

Isolators - Gate Drivers Procurement Notes

Verify component authenticity due to potential manufacturer transitions between NEC, Renesas, and CEL. Confirm lead configuration matches the L1 specification for long creepage distance. Check RoHS compliance status as documentation varies across sources. Ensure the specific suffix aligns with required packaging and termination standards for your assembly process.

Isolators - Gate Drivers Selection Notes

Select this component when high output current capability and fast switching speeds are required for power semiconductor gate drives. The DIP-8 package with bent leads offers enhanced isolation creepage compared to standard variants. Consider the 5000 Vrms isolation rating for applications requiring robust galvanic separation between control and power circuits.

Isolators - Gate Drivers Part Context

This device belongs to the PS9552 series of photocouplers designed specifically for power electronics applications. The series includes variants such as PS9552, PS9552L2, and PS9552L3, which differ primarily in package style and lead configuration. The PS9552L1 variant is distinguished by its through-hole DIP-8 package with bent leads to maximize insulation clearance.
