Diodes Incorporated SDT8A60VP5-13D

Overview

SDT8A60VP5-13D from Diodes Incorporated is a 60 V, 8 A trench Schottky barrier rectifier in PowerDI5 package, featuring 0.54 V max forward voltage at 8 A and 0.2 mA max reverse leakage at 60 V and +25°C. It serves as a high-efficiency freewheel or output rectifier in DC-DC converters and AC-DC adapters operating up to +150°C junction temperature.

For engineers reviewing the SDT8A60VP5-13D datasheet, SDT8A60VP5-13D pinout, SDT8A60VP5-13D application, or SDT8A60VP5-13D equivalent, key selection criteria include low VF stability across temperature, soft switching behavior for EMI reduction, thermal resistance (RθJC = 3°C/W on Al board), and RoHS-compliant green packaging with matte tin terminals.

Technical Context

This Schottky rectifier uses trench MOS structure to achieve lower forward voltage and improved high-temperature leakage control versus planar Schottky diodes. Its soft, fast recovery minimizes voltage ringing during turn-off in synchronous buck and flyback topologies.

The PowerDI5 package delivers 3°C/W junction-to-case thermal resistance on a 2"×2" aluminum board, enabling 8 A continuous conduction without forced air. Reverse leakage remains ≤50 µA at 125°C and VR = 60 V, supporting stable operation in thermally constrained power supplies.

Key Specifications

Pinout & Package

PowerDI5 is a 3-terminal surface-mount package with an exposed cathode pad for thermal and electrical connection. Cathode is connected to the large bottom metal pad; anode is accessed via two side terminals (pins 1 and 3).

FAQ

What is the recommended PCB pad layout for SDT8A60VP5-13D?

Diodes specifies a minimum 70% solder coverage on the exposed cathode pad using a thermal relief pattern per their PowerDI5 outline (DS42170, page 4). The recommended layout uses 2 oz. copper with thermal vias spaced ≤1 mm apart under the pad, connected to an internal ground plane for optimal RθJA = 18°C/W performance.

How does SDT8A60VP5-13D compare to standard Schottky diodes in thermal performance?

With RθJC = 3°C/W on a 2"×2" Al board, SDT8A60VP5-13D achieves 3× better junction-to-heatsink thermal transfer than typical SO-8 Schottkys (RθJC ≈ 9–12°C/W). This allows 8 A operation at TC ≤ 95°C without forced airflow-critical for fanless industrial power supplies.

Is SDT8A60VP5-13D suitable for automotive applications?

While not AEC-Q101 qualified, SDT8A60VP5-13D operates reliably from –55°C to +150°C and meets RoHS 3 and halogen-free requirements. It is used in non-safety-critical automotive subsystems (e.g., infotainment power rails) where qualification is not mandated, provided thermal design accounts for under-hood ambient extremes.

What is the meaning of the "D" suffix in SDT8A60VP5-13D?

The "D" suffix indicates 5,000-unit tape-and-reel packaging on a 13-inch reel with 12 mm carrier tape width-per Diodes' ordering convention (Note 5, DS42170). This format supports high-volume automated assembly and is distinct from the "13" variant, which lacks reel diameter specification.
