Procurement Notes

Verify the specific ordering suffix when purchasing. The base part number CAB011A12GM3 indicates the module without pre-applied phase change thermal interface material. If pre-applied TIM is required, the correct part number is CAB011A12GM3T. Confirm the exact configuration matches the system design requirements before finalizing orders.

Selection Notes

Select this component for applications requiring high power density and efficiency in medium power ranges. Ensure the heatsink temperature remains within limits to maintain the specified 149 A continuous current rating. Consider the stray inductance of 18.3 nH for layout optimization. Verify compatibility with recommended gate drive voltages of -4 V to +15 V for optimal performance.

Part Context

This module belongs to the Wolfspeed WolfPACK family, which offers baseplate-less designs for compact industrial applications. The WolfPACK series provides scalability across various configurations including half-bridge, six-pack, full-bridge, and T-type topologies up to 3.3 kV. This specific half-bridge variant targets systems needing reduced assembly overhead and improved thermal performance.

Replacement Considerations

Direct replacement requires matching the 1200 V rating, 11 mΩ RDS(on), and half-bridge topology. Verify that alternative modules support press-fit mounting or adapt the mechanical interface accordingly. Ensure the substitute component meets UL 1557 certification if isolation compliance is mandatory for the end application.
