SKRW093 CR Micro 45V 30A Schottky Barrier Diode Die

The CR Micro SKRW093 is a 45 V 30 A Schottky barrier diode in a Die package, Trench SBD construction. reverse leakage 120 µA, surge rating 300 A.

Key Specifications

Same-Rating Selection Table

14 part numbers share the same 45 / Die rating — sorted by vf max.

Applications

Low-voltage DC-DC converters, load switches, battery protection, and brushed or stepper motor drive.

Selection Notes

• VRRM is the peak repetitive rating, not a DC limit. Leave margin for ringing on the cathode.
• Trench Schottky parts trade leakage for forward drop. At high junction temperature the reverse leakage climbs sharply, so check the derating curve before using one in a high-ambient design.
• VF is quoted at a specified forward current. At lower currents the drop falls, which matters in low-load efficiency measurements.
• Where trr is not listed the part is a pure Schottky with no reverse recovery charge — confirm this on the datasheet before relying on it in a hard-switched leg.

Common Questions

What is the reverse voltage rating of the SKRW093?

VRRM is 45 V.

Does the SKRW093 have reverse recovery?

No trr figure is published for this part. It is a Schottky barrier diode, so conduction is majority-carrier and there is no minority-carrier recovery charge to account for.

What package does the SKRW093 come in?

Die. Check the datasheet mechanical drawing for lead spacing and thermal pad dimensions before laying out the footprint.

How do I choose between the 14 part numbers in this rating group?

All 14 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.
