APT30DQ60BCTG

Overview

APT30DQ60BCTG is a dual common cathode fast recovery rectifier manufactured by Microchip Technology. It features a 600 V maximum repetitive reverse voltage and supports a continuous forward current of 30 A. The device utilizes a TO-247-3 through-hole package, suitable for high-power applications. Key electrical characteristics include a forward voltage of 2 V at rated current and a reverse leakage current of 25 µA at full blocking voltage. The component offers a fast reverse recovery time of 30 ns and operates within a junction temperature range of -55°C to +175°C.

Feature Summary

• Dual common cathode configuration for bridge rectifier applications
• Fast recovery technology with 30 ns reverse recovery time
• High thermal stability supporting operation up to 175°C junction temperature

Applications

• High-frequency switching power supplies
• Uninterruptible power supply (UPS) systems
• DC-DC converter circuits

Procurement Notes

Verify the specific suffix BCTG against official Microchip documentation to confirm the dual common cathode configuration and TO-247-3 package variant. Ensure compatibility with existing thermal management designs due to the through-hole mounting style. Cross-reference datasheet revisions to validate electrical parameters before integration into production hardware.

Selection Notes

Select this component when a dual diode arrangement in a single package is required for space-constrained high-current designs. The 600 V rating provides adequate margin for standard industrial AC line voltages. Consider the 30 A continuous current capability and low reverse recovery charge for efficiency optimization in hard-switching topologies compared to standard recovery diodes.

Part Context

This part belongs to the APT series of fast recovery rectifiers from Microchip Technology, formerly known as Advanced Power Technology. The series is designed for general-purpose high-speed switching applications requiring robust performance and reliability. The TO-247-3 package allows for efficient heat dissipation and secure mechanical mounting via screw terminals.

Replacement Considerations

Direct replacements must match the 600 V / 30 A rating, dual common cathode configuration, and TO-247-3 footprint. Verify reverse recovery time and forward voltage specifications to ensure equivalent circuit performance.
