CAB530M12BM3

Overview

The Wolfspeed CAB530M12BM3 is a 1200 V, 530 A all-Silicon Carbide half-bridge power module. It features an industry-standard 62 mm footprint with a copper baseplate and aluminum nitride insulator. Key electrical parameters include a typical drain-source on-state resistance (RDS(on)) of 2.67 mΩ at 25 °C and a maximum gate-source voltage of +23 V transient. The module supports a continuous drain current of 719 A at 25 °C case temperature and operates within a virtual junction temperature range of -40 °C to 150 °C, with intermittent capability up to 175 °C. Stray inductance between terminals 1 and 3 is specified at 11.1 nH.

Feature Summary

• Ultra-low loss and high-frequency operation enabled by zero turn-off tail current from the MOSFET structure.
• Normally-off, fail-safe device operation ensuring inherent safety during gate signal loss.
• UL 1557 certified for electrically isolated semiconductor devices, facilitating compliance in industrial applications.

Applications

• Railway & Traction systems
• EV Charging Infrastructure
• Industrial Automation & Testing
• High-Frequency Power Supplies
• Renewable Energy Systems & Grid-Tied Inverters

Procurement Notes

Verify the specific ordering suffix when purchasing. The standard part number CAB530M12BM3 does not include pre-applied thermal interface material. If phase change thermal interface material is required for the application, the variant ending in 'T' (CAB530M12BM3T) must be selected. Confirm that the received unit matches the intended configuration regarding thermal preparation before integration into the system design.

Selection Notes

Select this module for designs requiring a compact 62 mm form factor to enable system retrofits or space-constrained layouts. Ensure the gate driver can support the recommended operating voltage of -4 V to +15 V. Consider the thermal management requirements based on the junction-to-case thermal resistance of 0.065 °C/W and the derating curves provided in the datasheet for the target case temperatures.

Part Context

This component belongs to the BM3 generation of Wolfspeed's 62 mm platform modules. It is designed as a direct mechanical and pin-compatible replacement for previous generations within the same footprint family, such as the BM2 series, allowing for performance upgrades without altering the primary PCB layout or cooling infrastructure.

Replacement Considerations

Direct mechanical substitutes within the 62 mm half-bridge format include other BM3 generation parts like the CAB450M12BM3 or CAB530M12XM3, though electrical ratings and RDS(on) values differ. Verify compatibility with existing gate drivers and thermal interface materials when swapping between variants.
