Procurement Notes

Verify the specific ordering suffix when purchasing. The base part number CAB5R0A23GM4 indicates the absence of pre-applied phase change thermal interface material. If pre-applied TIM is required for the application, the variant ending in T (CAB5R0A23GM4T) must be selected. Confirm that the procurement documentation matches the exact alphanumeric code to ensure correct physical configuration.

Selection Notes

Select this module for applications requiring 2300 V blocking capability and low on-resistance. Ensure the gate driver can support the recommended operational gate-source voltage range of -4 V to +15 V or +18 V. Verify that the system's stray inductance and external gate resistance align with the dynamic performance curves provided in the datasheet to optimize switching energy and manage dv/dt and di/dt rates effectively.

FAQ

What is the difference between CAB5R0A23GM4 and CAB5R0A23GM4T?

The primary difference is the inclusion of pre-applied phase change thermal interface material. The CAB5R0A23GM4 does not include pre-applied TIM, while the CAB5R0A23GM4T comes with it pre-installed.

Does this module exhibit zero turn-off tail current?

Yes, the module is fully SiC MOSFET-based and features zero turn-off tail current, which contributes to reduced switching losses compared to devices with minority carrier storage effects.

Is the module certified for safety compliance?

Yes, the module has been certified by Intertek Testing Solutions as an Electrically Isolated Semiconductor Device – Component in accordance with UL STD 1557.
