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 CRRI640L45S-S15?
VRRM is 45 V.
Does the CRRI640L45S-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 CRRI640L45S-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.
