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 CRRS40L45A?
VRRM is 45 V.
Does the CRRS40L45A 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 CRRS40L45A come in?
TO-263. Check the datasheet mechanical drawing for lead spacing and thermal pad dimensions before laying out the footprint.
