Overview
The APT75DQ120D is a single standard diode manufactured by Microchip Technology. It features a maximum average forward rectifying current of 75A and a maximum repetitive peak reverse voltage of 1200V. The device utilizes a D3PAK surface-mount package with TO-268AA footprint characteristics. Key electrical parameters include a forward voltage of 3.3V at 75A, a reverse leakage current of 100µA at 1200V, and a maximum junction temperature range from -55°C to +175°C.
Feature Summary
- High thermal stability supporting operation up to 175°C junction temperature
- Robust 1200V blocking capability for high-voltage applications
- Surface-mount D3PAK design for efficient PCB integration
Applications
- General-purpose power rectification circuits
- Freewheeling diodes in switching power supplies
- Industrial motor drive protection stages
Procurement Notes
Verify the specific datasheet revision and exact pinout configuration against your schematic before procurement. Confirm that the D3PAK footprint matches your PCB land pattern precisely. Ensure thermal management solutions accommodate the specified junction temperature limits during operation.
Selection Notes
Select this component when a 1200V rating and 75A continuous current capacity are required in a compact surface-mount form factor. Compare forward voltage drop specifications against alternative packages to ensure system efficiency targets are met within the available board space constraints.
Part Context
This part belongs to Microchip's discrete diode portfolio, specifically designed for general power electronics. It complements other high-voltage components in the APT series, offering a standardized solution for rectification tasks where space-saving surface-mount technology is preferred over through-hole alternatives.
Replacement Considerations
Check for direct substitutes such as the APT75DQ120BG or APT75DQ120JDQ3. Verify that any replacement maintains identical voltage ratings, current handling capabilities, and physical package dimensions to ensure compatibility without redesigning the host circuit board.
