Applications
- High-frequency switchmode power supplies
- Motor controller freewheeling circuits
- Uninterruptible power supply (UPS) output rectification
Procurement Notes
Verify the manufacturer marking on the component surface matches Microchip or its acquired entities like Microsemi. Confirm the suffix 'CTG' indicates the specific lead-free tube packaging variant. Cross-reference the datasheet revision date to ensure compatibility with current thermal management requirements. Check for any product change notifications regarding pinout or material composition updates.
Selection Notes
Select this component when designing systems requiring high blocking voltage combined with low conduction losses. The TO-247-3 package provides robust mechanical stability for high-current applications. Ensure the thermal design accommodates the 150°C maximum junction temperature limit. Compare forward voltage specifications against alternative Schottky arrays to optimize overall system efficiency.
Part Context
This part belongs to the APT series of high-voltage Schottky rectifiers originally developed by Advanced Power Technology before being integrated into Microchip's portfolio. The series is characterized by ultrafast recovery times and soft switching behavior. These devices are engineered to replace standard fast recovery diodes in applications where reduced switching losses and lower electromagnetic interference are critical performance factors.
