Overview
The APT30D40BG is a single fast recovery rectifier diode manufactured by Microchip Technology. It features a 400 V reverse voltage rating and a continuous forward current of 30 A. The device utilizes a TO-247-2 through-hole package with a tab for thermal management. Key electrical parameters include a maximum forward voltage of 2.5 V, a peak repetitive reverse current of 25 uA, and a surge current capability of 320 A. The component operates within a temperature range of -55°C to +175°C junction temperature.
Feature Summary
- Fast recovery rectifier design optimized for high-frequency switching applications
- Robust thermal performance via TO-247-2 through-hole mounting configuration
- High surge current handling capacity for transient protection
Applications
- High-frequency power supply circuits
- Motor drive rectification stages
- Industrial inverter systems
Procurement Notes
Verify the specific datasheet revision and manufacturer lot codes upon receipt. Confirm that the TO-247-2 pinout matches your PCB footprint requirements. Ensure storage conditions comply with moisture sensitivity levels if applicable. Cross-reference official Microchip documentation for any recent design changes or obsolescence notices before finalizing procurement plans.
Selection Notes
Select this component when a 400 V blocking voltage and 30 A continuous current are required in a standard through-hole package. Consider the 32 ns recovery time for efficiency in high-frequency topologies. Evaluate thermal dissipation needs based on the 2.5 V forward voltage drop at rated current. Ensure the application environment stays within the specified -55°C to +175°C operating range.
Part Context
This part belongs to Microchip's Fast Recovery Epitaxial Diode (FRED) series. These devices are engineered for low reverse recovery charge and short recovery times. The TO-247-2 package provides a balance of electrical performance and mechanical robustness for industrial power electronics.
Replacement Considerations
Check for direct cross-references from other manufacturers offering identical 400V/30A FRED specifications in TO-247 packages. Verify pin compatibility and thermal resistance values before substitution.
