- High thermal stability with extended operating temperature range
- Robust construction for high surge current handling
Applications
- High-frequency power supplies
- Motor drive circuits
- Uninterruptible power systems (UPS)
- DC-DC converters
Procurement Notes
Verify the specific suffix 'BG' against official Microchip documentation to confirm pinout and mechanical dimensions. Ensure compatibility with TO-247AC mounting standards. Check for recent Product Change Notifications (PCN) or Errata sheets regarding dimensional updates. Confirm RoHS compliance status through the manufacturer's latest declaration. Validate supplier authenticity to avoid counterfeit components.
Selection Notes
Select this component for applications requiring fast recovery times and high voltage blocking capabilities. The TO-247 package offers efficient heat dissipation for moderate power levels. Consider the 1.2 kV rating for safety margins in higher voltage systems. Evaluate thermal management requirements based on the 15 A continuous current rating. Compare reverse recovery charge specifications against alternative FRED devices for efficiency optimization.
Part Context
This part belongs to Microchip's Advanced Power Transistor (APT) series, formerly associated with International Rectifier. The APT line focuses on high-performance discrete power semiconductors. The TO-247 package is standard for medium-to-high power diodes. This specific model targets industrial and automotive power conversion markets.
Replacement Considerations
Consult official Microchip substitution guides for verified equivalents. Generic replacements may differ in reverse recovery charge or thermal resistance. Verify that any substitute maintains the 1.2 kV rating and TO-247 footprint. Cross-reference datasheets for matching forward voltage and current ratings.
