Product details

The STPS15L30CB-TR is a dual Schottky rectifier from STMicroelectronics, configured as a common-cathode pair in a surface-mount DPAK package.

7.5 A per diode — sizing the thermal budget

At 7.5 A per diode the forward drop is 480 mV, which works out to about 3.6 W dissipation per leg at full rated current. The 1 mA reverse leakage at 30 V is typical for a 30 V Schottky at elevated temperature; at 125 °C junction it climbs, so derate the output current if the ambient is tight.

Active and available — no LTB risk

STMicroelectronics lists the STPS15L30CB-TR as an active product.

Frequently asked questions

What is the difference between STPS15L30CB and STPS15L30CB-TR?

The STPS15L30CB and STPS15L30CB-TR are the same silicon die and package. The -TR suffix indicates Tape & Reel packaging for automated pick-and-place assembly. The STPS15L30CB without the suffix typically ships in tube or bulk form. Electrically and thermally they are identical.

Is STPS15L30CB-TR RoHS compliant?

Yes, the STPS15L30CB-TR is RoHS compliant. STMicroelectronics marks this part as RoHS compliant in its product documentation.

Is STPS15L30CB-TR suitable for high frequency applications?

Yes, the STPS15L30CB-TR is a Schottky diode with a fast recovery time of less than 500 ns at currents above 200 mA. This makes it suitable for switching frequencies in the tens to low hundreds of kilohertz range, typical of flyback and forward converters. For very high frequencies (above 1 MHz), a faster recovery or SiC diode may be needed.

What is the maximum current of STPS15L30CB-TR?

Each diode in the common-cathode pair is rated for 7.5 A average rectified current. The total package current depends on the duty cycle and thermal management, but the per-diode rating is 7.5 A.
