Overview
The APT30D40BCTG is a silicon-based Fast Recovery Epitaxial Diode (FRED) manufactured by Microchip Technology. It features a 400 V reverse voltage rating and a 30 A average forward current capability. The device exhibits a typical forward voltage of 1.3 V at rated current and a maximum surge current of 320 A. Reverse leakage current is specified at 250 uA, with a fast recovery time of 22 ns. It operates within a junction temperature range of -55°C to +175°C and is housed in a TO-247-3 through-hole package.
Feature Summary
- Fast recovery characteristics optimized for high-frequency switching applications
- High thermal stability supporting operation up to 175°C junction temperature
- Robust surge current handling capability for transient protection
Applications
- High-frequency power supply rectification
- Uninterruptible Power Supply (UPS) freewheeling diodes
- DC-DC converter output rectification
Procurement Notes
Verify the specific ordering suffix against official Microchip documentation to ensure correct pinout and electrical specifications. Confirm RoHS compliance status via the latest datasheet or environmental declaration. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.
Selection Notes
Select this component when a 400 V blocking voltage and 30 A continuous current are required in a TO-247-3 package. Ensure the application demands a 22 ns reverse recovery time suitable for fast-switching topologies. Verify that the thermal management design supports the device's power dissipation limits at the intended operating junction temperature.
Part Context
This discrete semiconductor module belongs to Microchip's FRED diode portfolio, designed for efficient power conversion. It serves as a standalone rectifier element within larger power electronic systems. The TO-247-3 packaging facilitates reliable through-hole mounting on printed circuit boards for industrial and commercial power applications.
Replacement Considerations
Direct substitutes include APT30DQ60BCTG (600V variant) and APT30D30BCTG (300V variant). Verify voltage ratings and recovery times match application requirements when cross-referencing.
