Diodes Incorporated SDT15150VP5-13D

Overview

SDT15150VP5-13D 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/125°C, and TJ up to +150°C. It serves as a high-efficiency freewheel or blocking diode in DC-DC converters and AC-DC adapters where low conduction loss and thermal stability are critical.

For engineers reviewing the SDT15150VP5-13D datasheet, SDT15150VP5-13D pinout, SDT15150VP5-13D application, or SDT15150VP5-13D equivalent, key selection criteria include forward voltage at high current/temperature, reverse leakage under hot reverse bias, thermal resistance (RθJC = 3°C/W with heatsink), and PowerDI5 footprint compatibility with high-power density PCB layouts.

Technical Context

This Schottky rectifier uses trench MOS structure to reduce forward voltage while maintaining low leakage-unlike planar Schottkys, it achieves VF = 0.72 V at 15 A/125°C and IR = 20 µA at 150 V/125°C. Its soft, fast switching minimizes EMI in high-frequency switching topologies.

The PowerDI5 package enables dual thermal paths: RθJA = 18°C/W with 2"×2" Al board + heatsink, and RθJC = 3°C/W, supporting high-current operation without external heatsink in space-constrained designs.

FAQ

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

The SDT15150VP5-13D supports IO = 15 A continuously at TC ≤ 110°C, as shown in Figure 5 (DC Forward Current Derating). Exceeding this requires derating per the curve-e.g., at TC = 125°C, max IO drops to ~12.5 A. Thermal design must ensure RθJC × PD + TC ≤ 150°C.

Is the exposed pad electrically isolated or connected internally?

The PowerDI5 exposed pad is internally bonded to the cathode (K) terminal-not isolated. It must be soldered to a PCB copper area tied to the cathode net. Using it as a separate thermal pad without electrical connection violates the internal construction and risks shorting or thermal failure.

How does its leakage compare to standard Schottky rectifiers at 125°C?

At VR = 150 V and TJ = 125°C, SDT15150VP5-13D specifies IR ≤ 20 µA (typical), significantly lower than conventional planar Schottkys (often >100 µA at same conditions). This is achieved via trench isolation and optimized metallization, enabling reliable operation in high-temp industrial environments.

Can it replace a 15A/100V Schottky in an existing design?

No-VRRM = 150 V is not backward-compatible with 100 V-rated circuits. Substituting increases risk of overvoltage stress on downstream components. For 100 V systems, use Diodes' SDT15100VP5 (100 V, 15 A) which shares identical PowerDI5 footprint, VF, and thermal specs.
