CRJQ190N65G4F CR Micro 650V 16A N-Channel MOSFET TO-247

The CR Micro CRJQ190N65G4F is a 650 V 16 A N-channel MOSFET in a TO-247 package, built on the Super Junction process. On-resistance is 160 mΩ typical and 190 mΩ maximum at a 10 V gate drive; gate charge is 24 nC with 1030 pF input capacitance; threshold voltage spans 3 to 5 V.

Key Specifications

Same-Rating Selection Table

42 part numbers share the same 650 / TO-247 / N rating — sorted by rds(on) typ; first 40 shown.

Process Technology

Super Junction — alternating p/n pillars in the drift region cancel part of the vertical field, so Rds(on) grows almost linearly with breakdown voltage instead of quadratically. Best Rds(on) per unit area in the 500–800 V band, at the cost of a harder body-diode reverse recovery and more sensitivity to dv/dt during commutation.

Applications

Active PFC, server and telecom rectifiers, and half-bridge or full-bridge DC-DC with 650 V bus.

Selection Notes

• Rds(on) rises with junction temperature. Size the heatsink against the hot value given in the datasheet, not the 25 °C number in the table above.
• If the gate is driven below 10 V, check the 4.5 V Rds(on) line — parts without that rating are not characterised for logic-level drive.
• For high-frequency stages compare Qg and Ciss against the Rds(on) gain. A part one bin lower in Rds(on) often costs more switching loss than it saves in conduction.
• The body diode recovery of low-Rds(on) parts can be severe in bridge topologies. Verify dv/dt and dead time against the datasheet before dropping it into a half bridge.

Common Questions

Is the CRJQ190N65G4F an N-channel or P-channel device?

It is N-channel. The drain-source rating is 650 V.

Can the CRJQ190N65G4F be driven at 4.5 V?

No 4.5 V on-resistance figure is published for this part. It is characterised at 10 V gate drive, so use a driver that reaches 10 V.

What is the gate threshold voltage of the CRJQ190N65G4F?

VGS(th) is specified between 3 and 5 V. Below the lower figure the part is off; above the upper figure it is fully on at the rated current.

How much gate charge does the CRJQ190N65G4F need?

Qg is 24 nC. Size the driver against that figure at your switching frequency, and add the gate loop loss to the total dissipation budget.

What package does the CRJQ190N65G4F come in?

TO-247. Check the datasheet mechanical drawing for lead spacing and thermal pad dimensions before laying out the footprint.

How do I choose between the 42 part numbers in this rating group?

All 42 share the same voltage and package class. Sort by on-resistance first, then check gate charge: the lowest Rds(on) part is not automatically the best choice if the stage switches at high frequency. The table above lists them in ascending Rds(on) order.
