Procurement Notes

Verify the specific ordering suffix J1 corresponds to the TO-263-7L XL package variant when sourcing. Confirm RoHS compliance status through official Wolfspeed documentation channels prior to integration. Ensure that the selected component matches the exact datasheet revision required for your design specifications. Cross-reference part numbers carefully to distinguish between tape-and-reel and tube packaging options if applicable.

Selection Notes

Select this component for designs requiring high efficiency and reduced cooling requirements due to low switching losses. The separate Kelvin source pin facilitates precise gate drive control, minimizing parasitic inductance effects. Consider the thermal resistance and safe operating area curves when designing heat sinks for high-power density applications. Evaluate the gate charge requirements against available driver capabilities to optimize switching frequency performance.

FAQ

What is the purpose of the separate driver source pin?

The separate driver source pin (Kelvin source) isolates the gate drive return path from the high-current power source path. This minimizes ground bounce and reduces gate ringing during switching transitions, improving overall system stability and efficiency.

What is the maximum recommended gate-source voltage?

The maximum transient gate-source voltage is +19 V. For static operation, the recommended turn-on gate voltage is 15 V with a ±5% regulation tolerance. The minimum operational gate-source voltage is -4 V.

How does the on-resistance vary with temperature?

The on-resistance increases as the junction temperature rises. At 150 °C, the maximum on-resistance is specified at 53.5 mΩ, compared to a typical value of 40 mΩ at 25 °C under similar test conditions.
