• High humidity operation capability verified by THB-80 (HV-H3TRB) testing
• Ultra-low loss switching performance enabling high-frequency operation
• Zero reverse recovery charge from diodes and zero turn-off tail current from MOSFETs

Applications

• Induction heating systems
• Motor drives
• Renewable energy applications
• Railway auxiliary and traction systems
• EV fast charging infrastructure

Procurement Notes

Verify the specific ordering suffix when purchasing. The WAS310M17BM3 designation indicates the module without pre-applied phase change thermal interface material. The variant WAS310M17BM3T includes pre-applied thermal interface material. Confirm the exact part number required for your assembly process to ensure compatibility with your thermal management design.

Selection Notes

Select this module for high-power density applications requiring robust 1700 V blocking capability. Ensure the gate drive circuitry supports the recommended static gate-source voltage range of -4 V to +15 V. Verify that the cooling solution maintains the case temperature within limits to sustain the 307 A continuous current rating at 90 °C.

Part Context

This component belongs to Wolfspeed's BM3 generation of silicon carbide power modules. It utilizes a half-bridge configuration optimized for industrial environments. The device is part of a broader portfolio including compatible evaluation tools like the KIT-CRD-CIL17N-BM and gate driver boards such as the CGD1700HB2P-BM3.

Replacement Considerations

Direct replacements must match the 1700 V / 310 A rating and 62 mm footprint. Compatible alternatives within the same family include the CAS310M17BM3. Verify pinout compatibility and thermal resistance specifications before substituting.

FAQ

What is the difference between WAS310M17BM3 and WAS310M17BM3T?

The WAS310M17BM3 does not include pre-applied phase change thermal interface material, whereas the WAS310M17BM3T comes with pre-applied thermal interface material.

What is the maximum recommended gate-source voltage?

The maximum transient gate-source voltage is +23 V. The recommended static operating voltage is +15 V with a tolerance of ±5%.

Does this module exhibit reverse recovery energy?

Silicon Carbide Schottky diodes do not have reverse recovery energy in the traditional sense, but they contribute capacitive energy during switching transitions.
