Overview
The APT30D120BG is a single fast recovery epitaxial diode (FRED) manufactured by Microchip Technology. It utilizes silicon planar passivation technology and is housed in a TO-247-3 package for through-hole mounting. The device features a maximum repetitive peak reverse voltage of 1200 V and a continuous forward current rating of 30 A at 25 °C. Key electrical parameters include a maximum non-repetitive surge forward current of 210 A, a typical reverse recovery time of 370 ns, and a maximum junction temperature of 150 °C.
Feature Summary
- Soft recovery characteristics to minimize switching noise
- Ultrafast recovery times for high-frequency efficiency
- Low forward voltage drop for reduced conduction losses
Applications
- High-frequency power supply circuits
- Motor drive freewheeling applications
- DC-DC converter output rectification
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm pinout and thermal specifications. Ensure the procurement channel provides valid RoHS compliance certificates. Confirm that the TO-247-3 lead form matches the target PCB footprint requirements before finalizing orders.
Selection Notes
Select this component when designing circuits requiring a balance of moderate current handling and fast switching speeds. The TO-247-3 package offers robust mechanical stability for screw or clip mounting. Evaluate thermal management needs based on the 30 A continuous current rating and expected ambient operating temperatures.
Part Context
This part belongs to Microchip's discrete diode portfolio, specifically within the FRED category. It serves as a replacement for legacy fast recovery diodes in industrial and consumer electronics. The TO-247-3 form factor is widely adopted in medium-power conversion systems requiring reliable performance under high thermal stress.
Replacement Considerations
Cross-reference with other 1200 V, 30 A FRED diodes in the TO-247-3 package. Verify compatibility regarding reverse recovery charge and forward voltage characteristics to ensure circuit performance remains unchanged during substitution.
