CRME0308D CR Micro 30V 27A Dual MOSFET PDFN5x6D

The CR Micro CRME0308D is a 30 V 27 A N-channel dual MOSFET in a PDFN5x6D package. The package carries two independent N-channel dies. On-resistance is 15 mΩ typical and 18 mΩ maximum at a 10 V gate drive; 22 mΩ typical at 4.5 V, so it also works from a logic-level driver; threshold voltage spans 1 to 1.8 V.

Key Specifications

Same-Rating Selection Table

2 part numbers share the same 30 / PDFN5x6D / 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 CRME0308D an N-channel or P-channel device?

It is N-channel. The drain-source rating is 30 V.

Can the CRME0308D be driven from a 4.5 V logic-level gate signal?

Yes. The datasheet characterises Rds(on) at 4.5 V: 22 mΩ typical and 21.6 mΩ maximum.

What is the gate threshold voltage of the CRME0308D?

VGS(th) is specified between 1 and 1.8 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 CRME0308D come in?

PDFN5x6D. 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.
