A390P

Single Diodes Overview

The A390P is a standard recovery silicon rectifier manufactured by Powerex Inc. It features a maximum DC reverse voltage (Vr) of 1000 V and an average rectified current (Io) of 400 A. The device utilizes a DO-200AA (A-PUK) press-fit package for base mounting. Key electrical parameters include a forward voltage (Vf) of 1.7 V at 800 A, a reverse leakage current of 50 mA at 2200 V, and a reverse recovery time (trr) of 6 µs. It operates within a junction temperature range of -40°C to 125°C.

Single Diodes Procurement Notes

Verify the specific suffix against official datasheets to confirm exact electrical ratings and pinout configurations. Ensure compatibility with existing thermal management solutions due to the high current handling requirements. Confirm RoHS compliance status if required by project specifications. Validate that the DO-200AA form factor fits the mechanical constraints of the target assembly.

Single Diodes Selection Notes

Select this component when a high-current, high-voltage standard recovery diode is required in a press-fit package. Compare Vf and trr values against circuit requirements to ensure efficiency and switching performance meet design goals. Consider the thermal resistance of the DO-200AA package for heat dissipation planning. Verify that the 400 A average current rating aligns with the peak load demands of the application.

Single Diodes Part Context

The A390P belongs to the A390 series of silicon rectifiers from Powerex. This series is designed for robust industrial applications requiring reliable high-power rectification. The DO-200AA package provides a standardized interface for press-fit mounting on printed circuit boards or busbars, facilitating easy integration into high-current power modules.

Single Diodes Replacement Considerations

Check for direct cross-references in manufacturer substitution guides. Verify that any alternative part matches the 1000 V Vr, 400 A Io, and DO-200AA package dimensions. Ensure reverse recovery time and forward voltage characteristics are compatible with the original circuit design.
