Diodes Incorporated SDT15150VP5-13

Overview

SDT15150VP5 from Diodes Incorporated is a 15A, 150V Trench Schottky Barrier Rectifier in PowerDI5 package, featuring VF = 0.72 V at 15 A and +125°C, IR = 80 µA at 150 V and +25°C, and TJ(max) = +150°C. It serves as a high-efficiency freewheel or blocking diode in DC-DC converters and AC-DC adapters.

For engineers reviewing the SDT15150VP5 datasheet, SDT15150VP5 pinout, SDT15150VP5 application, or SDT15150VP5 equivalent, key selection criteria include low forward voltage at high temperature, stable reverse leakage under thermal stress, soft switching behavior, and compact thermally enhanced PowerDI5 packaging for space-constrained power stages.

Technical Context

This Schottky rectifier uses trench MOS structure to reduce forward voltage while maintaining low leakage-unlike planar Schottky diodes, it achieves 0.72 V VF at 15 A and +125°C. Its junction-to-case thermal resistance is 3 °C/W with heatsink, enabling high-current operation without forced cooling.

The device exhibits soft, fast reverse recovery (no minority-carrier storage), eliminating snubber requirements in synchronous buck or flyback secondary-side rectification. Reverse leakage remains ≤20 µA at VR = 150 V and TJ = +125°C, supporting reliable operation in high-temperature industrial and adapter environments.

FAQ

What is the maximum allowable case temperature for continuous operation?

The SDT15150VP5 supports continuous operation up to TC = +115°C, as derived from its +150°C maximum junction temperature and thermal derating curve (Figure 5). At TC = +115°C, IO(AV) remains rated at 15 A when mounted on a 2-inch × 2-inch aluminum board with 50 mm × 50 mm × 23 mm heatsink per datasheet Note 7.

Does this diode require a snubber circuit in high-frequency switching applications?

No. The SDT15150VP5 is a Schottky barrier rectifier with no minority-carrier storage, resulting in negligible reverse recovery charge (Qrr ≈ 0) and inherently soft, fast switching. This eliminates voltage spikes and ringing, making snubber circuits unnecessary in typical 100 kHz–1 MHz DC-DC topologies.

Is the PowerDI5 package lead-free and RoHS compliant?

Yes. The SDT15150VP5 features a matte tin finish over copper leadframe and conforms to EU RoHS directives 2002/95/EC, 2011/65/EU, and 2015/863/EU. It is also halogen- and antimony-free ("Green"), with bromine and chlorine content below 900 ppm each and antimony below 1000 ppm.

How does thermal performance differ between FR-4 PCB and aluminum heatsink mounting?

On standard 1-layer FR-4 (2 oz copper), RθJA = 88 °C/W limits usable power to ~0.5 W. With a 2-inch × 2-inch aluminum board and 50 mm × 50 mm × 23 mm heatsink, RθJA drops to 18 °C/W and RθJC to 3 °C/W-enabling >10 W dissipation. Thermal pad soldering to PCB copper is mandatory to achieve specified ratings.
