Overview
The APT15DQ120KG is a single ultrafast soft recovery rectifier diode manufactured by Microchip Technology. It features a 1200 V reverse voltage rating and a 15 A forward current capability in a TO-220-2 through-hole package. Key electrical parameters include a maximum forward voltage of 3.06 V, a reverse leakage current of 100 uA, and a recovery time of 300 ns. The device supports a maximum surge current of 80 A and operates within a temperature range of -55 C to +175 C junction temperature.
Feature Summary
- Ultrafast soft recovery characteristics for reduced switching losses
- Low forward voltage drop for improved efficiency
- Low leakage current for stable high-temperature operation
Applications
- High-frequency power supplies
- Uninterruptible power systems (UPS)
- DC-to-AC inverters
Procurement Notes
Verify the specific suffix 'KG' against the official Microchip datasheet to confirm pinout and thermal specifications. Ensure the procurement channel provides valid RoHS compliance documentation. Confirm that the TO-220-2 package matches the required PCB footprint and mounting constraints for the target assembly.
Selection Notes
Select this component when a 1200 V blocking voltage and 15 A continuous current are required in a standard through-hole configuration. The soft recovery profile makes it suitable for resonant converters where low electromagnetic interference is critical. Compare the 300 ns recovery time against system switching frequency requirements to ensure adequate performance margins.
Part Context
This part belongs to the APT series of Fast Recovery Epitaxial Diodes from Microchip Technology. It is designed for medium to high-power applications requiring fast switching speeds. The TO-220-2 package provides robust mechanical stability and efficient heat dissipation for industrial environments.
Replacement Considerations
Cross-reference with other Microchip APT15DQ series variants such as APT15DQ100KG or APT15DQ140KG if voltage ratings differ. Verify compatibility with equivalent parts from other manufacturers only if electrical parameters and package dimensions match exactly.
