- Product Details
- Download
- 20 V / 7 A continuous drain current, SOP-8 package
- Qg 7.2 nC and Ciss 361 pF
- N-channel, dual configuration
The CR Micro CRMM9926 is a 20 V 7 A N-channel dual MOSFET in a SOP-8 package. The package carries two independent N-channel dies. 25 mΩ typical at 4.5 V, so it also works from a logic-level driver; threshold voltage spans 0.4 to 1 V.

2 part numbers share the same 20 / SOP-8 / dual 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 CRMM9926 an N-channel or P-channel device?
It is N-channel. The drain-source rating is 20 V.
Can the CRMM9926 be driven from a 4.5 V logic-level gate signal?
Yes. The datasheet characterises Rds(on) at 4.5 V: 25 mΩ typical and 30 mΩ maximum.
What is the gate threshold voltage of the CRMM9926?
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.
What package does the CRMM9926 come in?
SOP-8. 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.
