Overview
The APT15D120KG is a fast recovery rectifier diode manufactured by Microchip Technology. It utilizes silicon technology and is housed in a TO-220-2 through-hole package. The device supports a maximum reverse voltage of 1.2 kV and a continuous forward current of 15 A. Key electrical parameters include a surge forward current rating of 110 A, a typical forward voltage drop, and a reverse recovery time of 32 ns. It operates within a junction temperature range of -55°C to +175°C.
Feature Summary
- Ultrafast recovery characteristics with soft recovery behavior
- Low forward voltage drop for improved efficiency
- Low leakage current performance
- Robust construction suitable for high-reliability applications
Applications
- High-frequency switching power supplies
- Free-wheeling diodes in motor drives
- DC-DC converters
- Induction heating systems
Procurement Notes
Verify the specific suffix 'KG' against the official Microchip datasheet to confirm pinout and thermal specifications. Ensure the ordering quantity aligns with manufacturer minimums. Confirm RoHS compliance status via the latest product change notification or datasheet revision history before finalizing procurement.
Selection Notes
Select this component when a 1.2 kV blocking capability and 15 A continuous current are required in a standard TO-220 form factor. The 32 ns reverse recovery time makes it suitable for higher frequency applications compared to standard recovery diodes. Evaluate thermal management requirements based on the 110 A surge rating and expected duty cycle in the target circuit design.
Part Context
This part belongs to Microchip's (formerly Microsemi) ultrafast recovery diode portfolio. It is designed for general-purpose high-speed switching applications where low reverse recovery charge is critical. The TO-220-2 package provides a balance of electrical isolation and heat dissipation for medium-power circuits.
Replacement Considerations
Cross-reference with other 1.2 kV, 15 A ultrafast diodes in TO-220 packages. Verify that substitute parts match the 32 ns reverse recovery time and forward voltage characteristics to ensure circuit compatibility.
