10 A Schottky in a hand-solderable package
The STPS1045SF is a 45 V, 10 A Schottky rectifier in the TO-277A (SMPC) surface-mount package — a footprint that's large enough for manual soldering with a fine-tip iron, yet compact enough for a production pick-and-place line.
Junction temperature and leakage trade-off
The 175°C max junction temperature gives headroom for high-ambient or poorly ventilated enclosures, but the 50 µA reverse leakage at 45 V doubles roughly every 10°C — at 125°C junction, expect leakage to climb into the low milliamps, which matters for standby power budgets. Its fast recovery (under 500 ns) suits it for switching supplies running at 50–200 kHz, where a standard rectifier would ring or overheat.
Active lifecycle and sourcing posture
The part is part of the ECOPACK®2 series, meaning it meets RoHS and halogen-free requirements without a separate exemption letter.
