Overview
The APT30D30BG is a single Fast Recovery Epitaxial Diode (FRED) manufactured by Microchip Technology. It features a 300 V reverse voltage rating and a continuous forward current of 30 A. The device utilizes a TO-247-2 through-hole package. Key electrical parameters include a maximum forward voltage of 1.3 V, a peak non-repetitive surge current of 320 A, and a reverse leakage current of 250 uA. The typical recovery time is 22 ns, with an operating temperature range from -55 °C to +175 °C.
Feature Summary
- Fast recovery epitaxial diode construction for high-speed switching applications
- High thermal stability supporting operation up to 175 °C junction temperature
- Robust surge current handling capability of 320 A
Applications
- High-frequency power supply rectification
- Induction heating circuits
- Motor drive freewheeling paths
Procurement Notes
Verify the specific ordering suffix and lead finish configuration against the manufacturer's latest documentation before procurement. Confirm that the TO-247-2 package variant matches the design requirements. Ensure compliance with export control regulations applicable to the transfer of this technology in your jurisdiction.
Selection Notes
Select this component when a single-diode configuration is required for 300 V systems. The 30 A rating suits moderate-power applications. Consider the 22 ns recovery time for frequency constraints. Verify thermal management needs given the 1.3 V forward voltage drop at full load.
Part Context
This part belongs to Microchip's FRED diode portfolio, designed for efficient power conversion. It serves as a discrete solution for replacing integrated modules in cost-sensitive designs. The TO-247 package provides robust mechanical mounting and heat dissipation capabilities compared to smaller surface-mount alternatives.
Replacement Considerations
Direct substitutes must match the 300 V / 30 A / TO-247-2 specifications. Verify equivalent recovery times and forward voltage characteristics to ensure circuit compatibility without redesign.
