- P-channel, dual configuration
The CR Micro CRMB0322D is a -30 V -16 A P-channel dual MOSFET in a PDFN3.3x3.3D package. The package carries two independent N-channel dies. On-resistance is 20 mΩ typical and 26 mΩ maximum at a 10 V gate drive; 27 mΩ typical at 4.5 V, so it also works from a logic-level driver; threshold voltage spans -1 to -2.2 V.

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 CRMB0322D an N-channel or P-channel device?
It is P-channel. The drain-source rating is -30 V.
Can the CRMB0322D be driven from a 4.5 V logic-level gate signal?
Yes. The datasheet characterises Rds(on) at 4.5 V: 27 mΩ typical and 36 mΩ maximum.
What is the gate threshold voltage of the CRMB0322D?
VGS(th) is specified between -1 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 CRMB0322D come in?
PDFN3.3x3.3D. 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.
