- 40 V / 28 A continuous drain current, TO-252-5 package
- Rds(on) 7 mΩ typ, 9 mΩ max at VGS = 10 V
- Qg 49 nC and Ciss 2283 pF
- N-channel, Common Drain configuration
The CR Micro CRMV0406D is a 40 V 28 A N-channel common-drain MOSFET in a TO-252-5 package. The two drains are tied internally, so the body diodes block in both directions. On-resistance is 7 mΩ typical and 9 mΩ maximum at a 10 V gate drive; 8 mΩ typical at 4.5 V, so it also works from a logic-level driver; threshold voltage spans 1.2 to 2.2 V.

2 part numbers share the same 40 / TO-252-5 / Common Drain rating — sorted by config.
Applications
Low-voltage DC-DC converters, load switches, battery protection, and brushed or stepper motor drive.
Selection Notes
- The two dies share a package but not a thermal path. Check whether the configuration is complementary, dual, common drain or series before wiring it into a topology.
- In complementary parts the N and P dies have different Rds(on) and Qg. Match the drive separately rather than assuming symmetry.
- Common-drain parts suit load switch and battery protection circuits where the two sources tie together — the body diodes then oppose each other and block in both directions.
- Because both dies sit on one leadframe, total dissipation is limited by the package, not by the individual die ratings.
Common Questions
Is the CRMV0406D an N-channel or P-channel device?
It is N-channel. The drain-source rating is 40 V.
Can the CRMV0406D be driven from a 4.5 V logic-level gate signal?
Yes. The datasheet characterises Rds(on) at 4.5 V: 8 mΩ typical and 10 mΩ maximum.
What is the gate threshold voltage of the CRMV0406D?
VGS(th) is specified between 1.2 and 2.2 V. Below the lower figure the part is off; above the upper figure it is fully on at the rated current.
What package does the CRMV0406D come in?
TO-252-5. Check the datasheet mechanical drawing for lead spacing and thermal pad dimensions before laying out the footprint.
How do I choose between the 2 part numbers in this rating group?
All 2 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.
