Overview
The Powerex Inc. A390D is a standard recovery silicon rectifier diode designed for high-current applications. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current rating of 400 A. The device utilizes a DO-200AA (A-PUK) clamp-on package, specifically configured with an R62 mounting interface for secure mechanical attachment. Electrical characteristics include a maximum forward voltage drop of 1.4 V at the rated current and a reverse leakage current of 25 mA at the maximum reverse voltage. The component operates within a junction temperature range of -40°C to 125°C.
Feature Summary
- High current handling capability with a 400 A average forward rectified current rating
- Robust mechanical design utilizing a clamp-on installation method for reliable thermal contact
- Standard recovery speed characteristics suitable for general-purpose power conversion
Applications
- Industrial motor drive rectification circuits
- DC power supply input stages
- Welding equipment power modules
Procurement Notes
Verify the specific suffix designation against the manufacturer's official datasheet to confirm electrical parameters and pinout compatibility. Ensure that the procurement documentation explicitly states the R62 mounting configuration to match the intended mechanical assembly requirements. Cross-reference the RoHS compliance status with current regulatory standards before finalizing the order.
Selection Notes
Select this component when a 400 V blocking voltage and 400 A continuous current capacity are required in a clamp-on form factor. Consider the standard recovery time if faster switching speeds are not critical for the application. Evaluate the thermal management solution to ensure the junction temperature remains within the specified operating range under maximum load conditions.
Part Context
The A390D belongs to the A390 series of single diodes manufactured by Powerex Inc. This series is characterized by its use in heavy-duty power electronics where high current density and robust mechanical mounting are essential. The DO-200AA package provides a standardized footprint for integration into larger power assemblies.
Replacement Considerations
Compatible substitutes within the same series include the A390M (600V) and A390PD (1400V), provided the voltage ratings exceed the circuit requirements. Verify that any replacement maintains the 400 A current rating and compatible R62 mounting interface.
