APT15D100BCTG

Overview

The APT15D100BCTG is a fast recovery rectifier diode manufactured by Microchip Technology, housed in a TO-247-3 package. It features a maximum repetitive reverse voltage of 1000 V and an average forward current rating of 15 A. The device exhibits a maximum forward voltage of 1.9 V at rated current and a typical reverse recovery time of 28 ns. Additional specifications include a peak non-repetitive surge current capacity of 120 A and a maximum reverse leakage current of 10 µA. The component operates within a junction temperature range of -55 °C to +150 °C and complies with RoHS standards.

Feature Summary

• Fast recovery characteristics with a typical reverse recovery time of 28 ns for efficient switching applications
• High voltage capability with a 1000 V repetitive reverse voltage rating
• Robust thermal performance supporting operation up to a 150 °C junction temperature
• Common cathode dual configuration integrating two diodes in a single three-terminal package

Applications

• High-frequency DC-DC converters
• Free-wheeling rectification in motor drives
• Inductive load switching circuits
• Power supply output rectification

Procurement Notes

Verify the specific suffix 'BCTG' to ensure compliance with RoHS directives and lead-free terminal finish requirements. Confirm that the TO-247-3 package dimensions align with the target PCB footprint and thermal management strategy. Cross-reference the manufacturer part number against official Microchip databases to avoid counterfeit components. Ensure storage conditions maintain integrity prior to surface mounting or through-hole assembly processes.

Selection Notes

Select this component when high-voltage isolation and rapid switching speeds are critical. The 15 A current rating suits moderate power levels requiring low conduction losses. Evaluate the 1.9 V forward voltage drop against thermal dissipation constraints in the final enclosure. Consider the common cathode arrangement for bridge-less or synchronous rectification topologies where space efficiency is prioritized over discrete single-diode solutions.

Part Context

This device belongs to the APT series of fast recovery epitaxial diodes from Advanced Power Technology, now integrated into Microchip's portfolio. The series targets industrial and consumer power electronics demanding improved efficiency. The TO-247-3 form factor provides superior heat sinking capabilities compared to smaller packages, making it suitable for chassis-mounted applications requiring robust thermal handling under continuous load conditions.

Replacement Considerations

Direct substitutes include the APT15DQ100KGVAO, which shares similar electrical ratings but utilizes a TO-220 package. Verify pinout compatibility and mechanical mounting differences before substitution. Alternative fast recovery diodes must match the 1000 V reverse voltage and 15 A forward current thresholds while maintaining comparable reverse recovery times to preserve circuit timing and efficiency.
