概述
Description
STTH1003SB-TR is STMicroelectronics’ ultrafast (fast-recovery) rectifier diode in a surface-mount, tape-and-reel package. It’s designed for high-frequency rectification in switch-mode power supplies and other power-electronics topologies, offering fast reverse-recovery, relatively low forward voltage drop, and good surge handling.
Key points:
- Part of the STTH ultrafast family, used to convert AC to DC in SMPS, adapters, and similar circuits.
- Typical ratings: high reverse-voltage capability (kilovolt range) and moderate forward current (on the order of a few amperes); precise values vary by variant.
- Features: fast recovery time, robust surge capability, and reliable operation when properly heatsinked.
- Packaging: surface-mount, tape-and-reel (TR) for automated assembly; polarity indicated by the cathode band.
- See the datasheet for exact VRRM, IF(AV), IFSM, VFM, trr, and thermal specs.
If you’re selecting it, verify the exact electrical ratings and thermal conditions in the latest ST datasheet.
