Diodes Incorporated SDT15150VP5-7

Overview

SDT15150VP5 from Diodes Incorporated is a 15A, 150V Trench Schottky Barrier Rectifier in PowerDI5 package, featuring VF ≤ 1.00 V at 15 A/25°C, IR ≤ 80 µA at 150 V/25°C, and TJ up to +150°C. It serves as a high-efficiency freewheel or output rectifier in DC-DC converters and AC-DC adapters where low conduction loss and thermal stability are critical.

For engineers reviewing the SDT15150VP5 datasheet, SDT15150VP5 pinout, SDT15150VP5 application, or SDT15150VP5 equivalent, key selection criteria include forward voltage at full load, reverse leakage at elevated temperature, thermal resistance junction-to-case (3°C/W with heatsink), and compatibility with compact surface-mount layouts requiring <1 mm profile height.

Technical Context

This Schottky rectifier uses trench MOS-enhanced architecture to reduce forward voltage while maintaining low reverse leakage across -55°C to +150°C operation. Its soft, fast switching behavior minimizes EMI in high-frequency switching topologies without requiring snubbers.

The PowerDI5 package delivers RθJC = 3°C/W when mounted on a 50 mm × 50 mm × 23 mm aluminum heatsink, enabling 15 A continuous conduction without forced air cooling. Junction capacitance is 10,000 pF at VR = 4 V, supporting stable operation in buck and flyback secondary-side rectification.

FAQ

What is the maximum allowable case temperature for continuous 15 A operation?

The SDT15150VP5 supports 15 A continuous current up to TC = 110°C, as shown in Figure 5 (DC Forward Current Derating). At TC = 110°C, IO remains rated at 15 A when mounted on a 50 mm × 50 mm × 23 mm aluminum heatsink per Note 7. Exceeding this case temperature requires linear derating per the curve.

Does SDT15150VP5 require a thermal pad connection to PCB ground?

Yes - the exposed pad (EP) is electrically connected to the cathode and must be soldered to a PCB thermal pad tied to the cathode net. This connection provides both the primary thermal path (RθJC = 3°C/W) and electrical return. Omitting the pad connection increases RθJA to 88°C/W and risks thermal runaway at full load.

Can SDT15150VP5 replace a standard PN-junction rectifier in an existing design?

Yes, provided reverse voltage rating (150 V) and surge current (250 A) meet system requirements. Its lower VF reduces conduction loss by ~30% versus a typical 15 A PN rectifier, but note its higher IR at high temperature - verify leakage does not affect standby regulation in low-power modes.

Is SDT15150VP5 qualified for automotive applications?

No - SDT15150VP5 is not AEC-Q101 qualified. Diodes offers automotive-grade variants (e.g., SDT15150VP5Q) with PPAP documentation and IATF 16949 manufacturing. For non-safety-critical 12 V accessory circuits, qualification may be pursued via customer-specific change control, but standard SDT15150VP5 is intended for industrial and commercial use.
