CRJQ80N65G4FQ
650 V Super Junction MOSFET, 33 A, 69 mOhm typical, TO-247, for PFC and switched-mode supplies.
650 V Super Junction N-channel MOSFET rated 33 A with 69 mOhm typical on-resistance in a TO-247 package, aimed at power-factor-correction stages, switched-mode supplies and inverter auxiliary rails.
FAE Professional Review
The CRJQ80N65G4FQ is the part we specify most often for 650 V hard-switched stages in the 100 W to 1 kW range. The charge-balanced Super Junction drift region keeps conduction loss low at 33 A, and the TO-247 outline gives a robust thermal path without the isolation complexity of a fully isolated package. For higher current in the same voltage class, step up to the CRJSH38N65G4FQ, which drops RDS(on) further and moves to the T2PAK outline to trim height and parasitic inductance.

Frequently Asked Questions
What designs is the CRJQ80N65G4FQ best suited to?
It fits 650 V hard-switched stages such as PFC front ends, flyback and LLC supplies and inverter auxiliary rails, where 33 A of current and 69 mOhm typical on-resistance balance loss and cost.
If you need higher current, the CRJSH38N65G4FQ is the sibling part.
How should I drive the gate and manage EMI?
Use a gate resistor tuned to your dv/dt and EMI target, keep the gate loop short and return the source directly to the driver. A small snubber or ferrite can damp high-frequency ringing if the layout is tight.
Our Super Junction troubleshooting article covers oscillation and EMI fixes.
What are the practical losses at my switching frequency?
Conduction loss scales with RDS(on) times RMS current squared, and switching loss scales with gate charge and output capacitance times frequency. Below about 100 kHz this part balances both terms well.
Our FAE team can estimate both at your operating point.
How does it compare with the CRJSH38N65G4FQ?
Both are 650 V Super Junction parts, but the CRJSH38N65G4FQ carries a higher 72 A rating and a lower 27 mOhm typical RDS(on) in a T2PAK package. The CRJQ80N65G4FQ keeps the familiar TO-247 footprint at lower cost.
Choose by current level and package preference.
