APT06DC60HJ

Bridge Rectifier Overview

The APT06DC60HJ is a Silicon Carbide (SiC) Schottky diode full bridge power module manufactured by Microsemi. It features a maximum DC reverse voltage of 600 V and an average forward current rating of 6 A at a case temperature of 100°C. The device exhibits a typical forward voltage of 1.8 V at 6 A and 25°C, with a non-repetitive forward surge current capability of 210 A. Electrical characteristics include a maximum reverse leakage current of 200 µA at 600 V and 25°C. The module utilizes an ISOTOP® SOT-227 package, providing a junction-to-case thermal resistance of 3.5 °C/W and an RMS isolation voltage of 2500 V.

Bridge Rectifier Procurement Notes

Verify component authenticity through authorized Microsemi distributors or official channels. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to your production timeline. Ensure proper electrostatic discharge handling procedures are followed during storage and assembly, as specified in application note APT0502.

Bridge Rectifier Selection Notes

Select this component for applications requiring high-frequency rectification where low switching losses and noise are critical. The 600 V rating and 6 A current capacity suit compact power designs. Consider the 3.5 °C/W thermal resistance for heatsink sizing calculations. Verify that the operating environment supports the -55°C to 175°C junction temperature range.

Bridge Rectifier Part Context

This part belongs to the Microsemi ISOTOP® series of SiC diode modules. It shares the SOT-227 form factor with other devices in the family but differs in electrical ratings based on the semiconductor material and internal configuration. The 'HJ' suffix typically denotes specific packaging or compliance variations within the product line.

Bridge Rectifier Replacement Considerations

Direct replacements must match the 600 V reverse voltage, 6 A current rating, and SOT-227 ISOTOP® package dimensions. Substitutes should offer comparable SiC performance characteristics, including low capacitance and fast switching speeds, to maintain circuit efficiency and thermal management requirements.

Bridge Rectifier FAQ

What is the maximum RMS isolation voltage between terminals and the case?

The maximum RMS isolation voltage is 2500 V when tested for 1 minute with an isolation current less than 1 mA at 50/60 Hz.
