CRRI730L45X-S15 CR Micro 45V 30A Schottky Barrier Diode R-6T-S15

The CR Micro CRRI730L45X-S15 is a 45 V 30 A Schottky barrier diode in a R-6T-S15 package, Trench SBD construction. forward drop 0.52 V maximum, reverse leakage 50 µA, surge rating 800 A.

Key Specifications

Same-Rating Selection Table

2 part numbers share the same 45 / R-6T-S15 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 CRRI730L45X-S15?

VRRM is 45 V, 51 V typical.

What is the forward voltage drop of the CRRI730L45X-S15?

VF is 0.52 V maximum and 0.478 V typical.

Does the CRRI730L45X-S15 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 CRRI730L45X-S15 come in?

R-6T-S15. 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.
