What are the key features of STPS15L30CB?
- Ultra-low 0.57 V maximum forward voltage drop reducing conduction losses at 15 A continuous output current
- Common-cathode dual-element configuration in DPAK-3 package enabling single-package full-wave rectification
- Fast-recovery Schottky silicon construction suited for high-frequency freewheeling in DC-DC converters up to 30 V
What is STPS15L30CB used for?
The STPS15L30CB is used as an output rectifier and freewheeling diode in step-down (buck) DC-DC converters, synchronous rectifier circuits, and battery chargers operating at voltages up to 30 V. Its low forward voltage of 0.57 V at 15 A minimizes conduction losses in high-current switching stages, improving overall converter efficiency. It is well suited for automotive, telecom, and industrial power modules where compact DPAK footprint and thermal performance are critical.

Frequently Asked Questions
What is the maximum forward voltage of STPS15L30CB at full rated current?
The STPS15L30CB has a maximum forward voltage of 0.57 V at 15 A continuous current, which is significantly lower than standard silicon PN rectifiers that typically exhibit 0.7 V to 1.1 V. This low drop reduces conduction power loss to approximately 8.5 W at full load, improving converter efficiency in 12 V to 24 V output-stage designs.
How does the common-cathode configuration of STPS15L30CB simplify full-wave rectifier circuits?
The common-cathode dual configuration places both diode anodes separately accessible while sharing one cathode output terminal, allowing a single DPAK-3 package to form one leg of a center-tap full-wave rectifier. This eliminates one additional discrete diode and its associated PCB real estate, reducing component count by 50% in center-tap secondary winding rectifier designs rated up to 30 V at 15 A.
In what switching frequency range is STPS15L30CB most effective as a freewheeling diode?
As a Schottky fast-recovery diode, STPS15L30CB is effective from DC to beyond 1 MHz switching frequencies due to its majority-carrier conduction mechanism and minimal reverse recovery charge. In typical buck converter designs running at 200 kHz to 500 kHz with 12 V input and 5 V output at 10 A, it outperforms silicon fast-recovery PN diodes by reducing reverse recovery switching losses by more than 80%.
What thermal considerations apply when mounting STPS15L30CB in a high-current application?
The STPS15L30CB in DPAK-3 (TO-252AA) has a typical junction-to-case thermal resistance of around 5 °C/W, meaning at 8.5 W conduction loss the case temperature rises about 42 °C above ambient without a heatsink. For ambient temperatures up to 85 °C and junction limit of 150 °C, a heatsink or copper pour area of at least 1 cm² on a 2 oz copper PCB is recommended to stay within safe operating limits at full 15 A load.
