Procurement Notes

Verify the specific revision level against the datasheet Rev 3 documentation prior to procurement. Confirm that the ordering suffix FTG corresponds to the SP4 package outline and terminal configuration required for your PCB layout. Ensure handling procedures account for Electrostatic Discharge sensitivity as specified in application note APT0502.

Selection Notes

Select this component when high-frequency operation and ruggedness are required. The Kelvin source pin simplifies gate drive design by minimizing stray inductance effects. The integrated thermistor allows for closed-loop thermal management without external sensors. Verify that the 1000V rating and 43A current capacity align with the peak load requirements of the target power stage.

Part Context

This device belongs to the Microsemi Power MOS 7® family of FREDFET modules. It utilizes the SP4 package format, which provides symmetrical design and lead frames optimized for power connections. The module integrates two phase legs within a single isolated housing, offering a high level of integration for compact power electronics designs.

Replacement Considerations

Consult official substitution lists or contact Microchip Technology support for verified equivalent part numbers. Do not assume pin compatibility with other MOSFET modules without verifying electrical parameters and mechanical dimensions against the original specification.
