Product details

Active production, automotive-sourced Schottky

The 580 mV forward voltage drop at 15 A keeps conduction losses manageable in high-efficiency DC-DC converters, alternator rectification, and reverse-battery protection stages.

What the 580 mV Vf and 150 µA leakage mean for your BOM

At 15 A forward current each diode drops 580 mV typical, which translates to about 8.7 W of conduction loss per diode at full load — you need to budget for that heat in the PowerSO-20 exposed-pad layout. The reverse leakage is 150 µA at 60 V, which is typical for a 60 V Schottky at elevated junction temperature; the 150°C junction rating lets you run it hot, but leakage climbs with temperature, so derate the reverse voltage if the ambient is consistently above 100°C. The fast-recovery speed — under 500 ns at >200 mA — is standard for Schottky diodes and sufficient for 100-200 kHz switching in automotive converters, though not intended for high-frequency PFC stages.

Package and thermal: PowerSO-20 with exposed pad

The part comes in a 20-SOIC (0.433" wide, 11.00 mm width) with an exposed pad, sold as the PowerSO-20 supplier package. The common-cathode configuration means the two cathodes are tied internally, simplifying layout for center-tapped transformer secondaries or dual rectifier stages.

Frequently asked questions

Is STPS30H60CKY-TR AEC-Q101 qualified for automotive use?

Yes, the STPS30H60CKY-TR carries AEC-Q101 qualification, meaning it is qualified for automotive-grade applications including engine control units, transmission modules, and body electronics. The automotive grade and 150°C junction rating support under-hood and high-temperature environments.

What are the equivalent or replacement parts for STPS30H60CKY-TR?

For a second-source option within the same STPS30 base family, look at other STPS30H60Cxx variants in different packages — but verify pin compatibility and thermal performance for the PowerSO-20 footprint. No direct pin-compatible second source from another manufacturer is recorded in this listing.
