CRSD090N10N4Z CR Micro 100V 74A N-Channel MOSFET TO-252 or DPAK

The CR Micro CRSD090N10N4Z is a 100 V 74 A N-channel MOSFET in a TO-252 or DPAK package, built on the SGT process. On-resistance is 8.3 mΩ typical and 10 mΩ maximum at a 10 V gate drive; gate charge is 31 nC with 2130 pF input capacitance; threshold voltage spans 2.2 to 3.8 V.

Key Specifications

Same-Rating Selection Table

15 part numbers share the same 100 / TO-252 or DPAK / N rating — sorted by rds(on) typ.

Process Technology

SGT (Shielded Gate Trench) — a trench gate with a grounded shield electrode beneath it. The shield cuts the gate-drain capacitance, so Qg and Crss drop sharply against a conventional trench at the same Rds(on). This is the workhorse process for 30–200 V and for 600–650 V high-frequency switching.

Applications

Synchronous rectification in 12–48 V rails, point-of-load converters, and hot-swap circuits.

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 CRSD090N10N4Z an N-channel or P-channel device?

It is N-channel. The drain-source rating is 100 V.

Can the CRSD090N10N4Z 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 CRSD090N10N4Z?

VGS(th) is specified between 2.2 and 3.8 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 CRSD090N10N4Z need?

Qg is 31 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 CRSD090N10N4Z come in?

TO-252 or DPAK. Check the datasheet mechanical drawing for lead spacing and thermal pad dimensions before laying out the footprint.

How do I choose between the 15 part numbers in this rating group?

All 15 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.
