- Qg 20.5 nC and Ciss 2739 pF
- N-channel, Trench process
The CR Micro CRTM052N02S2-G is a 20 V 80 A N-channel MOSFET in a PDFN5×6 package, built on the Trench process. 3.1 mΩ typical at 4.5 V, so it also works from a logic-level driver; gate charge is 20.5 nC with 2739 pF input capacitance; threshold voltage spans 0.4 to 1 V.

Process Technology
Trench — the gate is etched vertically into the drift region, multiplying channel width per unit area. Lowest Rds(on) in the sub-200 V range; the trade-off is higher Qg and a more fragile body diode under hard commutation.
Applications
Low-voltage DC-DC converters, load switches, battery protection, and brushed or stepper motor drive.
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 CRTM052N02S2-G an N-channel or P-channel device?
It is N-channel. The drain-source rating is 20 V.
Can the CRTM052N02S2-G be driven from a 4.5 V logic-level gate signal?
Yes. The datasheet characterises Rds(on) at 4.5 V: 3.1 mΩ typical and 4.2 mΩ maximum.
What is the gate threshold voltage of the CRTM052N02S2-G?
VGS(th) is specified between 0.4 and 1 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 CRTM052N02S2-G need?
Qg is 20.5 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 CRTM052N02S2-G come in?
PDFN5×6. Check the datasheet mechanical drawing for lead spacing and thermal pad dimensions before laying out the footprint.
