Product details

Automotive dual Schottky for high-temp rectification

The STPS15H100CBY-TR is an automotive-grade Schottky diode array from STMicroelectronics, configured as a common-cathode pair in a DPAK package. The fast-recovery Schottky technology delivers switching speeds under 500 ns, which is adequate for 50-200 kHz DC-DC stages.

Conduction loss and thermal budget

At 7.5 A per diode, the 800 mV Vf translates to roughly 6 W conduction loss per die at full load. Reverse leakage is specified at 3 µA at 100 V — typical for a 100 V Schottky. Leakage doubles with every 10-15°C rise, so at 125°C junction the leakage current can reach tens of microamps, which is still manageable for most automotive loads.
