The CR Micro CRTS080P04L2-G is a -40 V -80 A P-channel MOSFET in a TO-263 or D2PAK package, built on the Trench process. On-resistance is 6.5 mΩ typical and 8 mΩ maximum at a 10 V gate drive; 8.3 mΩ typical at 4.5 V, so it also works from a logic-level driver; gate charge is 108 nC with 5691 pF input capacitance; threshold voltage spans -1 to -3 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 CRTS080P04L2-G an N-channel or P-channel device?
It is P-channel. The drain-source rating is -40 V.
Can the CRTS080P04L2-G be driven from a 4.5 V logic-level gate signal?
Yes. The datasheet characterises Rds(on) at 4.5 V: 8.3 mΩ typical and 10.5 mΩ maximum.
What is the gate threshold voltage of the CRTS080P04L2-G?
VGS(th) is specified between -1 and -3 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 CRTS080P04L2-G need?
Qg is 108 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 CRTS080P04L2-G come in?
TO-263 or D2PAK. Check the datasheet mechanical drawing for lead spacing and thermal pad dimensions before laying out the footprint.
