APT60D30BG

Overview

The APT60D30BG is a silicon ultrafast soft recovery rectifier diode manufactured by Microsemi. It features a maximum DC reverse voltage of 300V and an average forward current rating of 60A at a case temperature of 143°C with a 0.5 duty cycle. The device supports a non-repetitive peak forward surge current of 600A. Electrical characteristics include a typical forward voltage of 1.4V at 60A, a maximum reverse leakage current of 250µA at rated voltage, and a junction capacitance of 150pF at 200V reverse bias. The component operates within a junction and storage temperature range of -55°C to 175°C.

Feature Summary

• Ultrafast recovery times combined with soft recovery characteristics for reduced switching noise
• Low forward voltage drop and low leakage current to minimize conduction losses
• Designed for cooler operation and higher reliability in power systems
• Available in popular TO-247 through-hole or surface mount D3PAK packages

Applications

• Anti-parallel diode in switchmode power supplies and inverters
• Free wheeling diode in motor controllers, converters, and inverters
• Snubber diode applications
• Power factor correction (PFC) circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and terminal finish. The 'G' suffix indicates RoHS compliance and lead-free terminals. Ensure the procurement specification matches the required thermal resistance and mounting torque limits for the selected package variant. Confirm availability of the TO-247 or D3PAK configuration as needed for the design.

Selection Notes

Select this component for high-frequency switching applications requiring low reverse recovery charge and current. Evaluate the thermal impedance curves to ensure adequate heat sinking for the desired duty cycle. Consider the soft recovery characteristic to minimize electromagnetic interference in sensitive circuits. Verify that the 300V blocking voltage provides sufficient margin for the specific circuit operating conditions.

Part Context

This part belongs to the APT60D30 series of ultrafast soft recovery rectifiers from Microsemi. The series includes variants such as APT60D30B and APT60D30S, distinguished primarily by their physical package configurations. The BG designation specifically denotes the TO-247 package with lead-free terminal finish compliant with RoHS standards.

Replacement Considerations

Direct substitutes within the same family include APT60D30B for standard leaded versions or APT60D30SG for surface mount RoHS-compliant options. Cross-brand replacements must match the 300V rating, 60A current capacity, and ultrafast soft recovery specifications.
