Diodes Incorporated SDT10100P5-13

Overview

SDT10100P5 from Diodes Incorporated is a 10A, 100V Trench Schottky Barrier Rectifier in PowerDI5 package, featuring 0.70 V max forward voltage at 10 A and 80 µA max reverse leakage at 100 V/25°C. It serves as a high-efficiency rectifier, freewheel diode, or blocking diode in DC-DC converters and AC-DC adapters operating up to +150°C junction temperature.

For engineers reviewing the SDT10100P5 datasheet, SDT10100P5 pinout, SDT10100P5 application, or SDT10100P5 equivalent, key selection criteria include low VF stability across temperature, soft fast switching behavior, thermal resistance (RθJC = 3°C/W on 2"×2" 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 devices. Its soft recovery minimizes EMI in switching power supplies, and the 150°C maximum junction temperature enables operation in thermally constrained environments without derating.

The PowerDI5 package delivers 3°C/W typical RθJC when mounted on a 2-inch aluminum board, enabling 10 A continuous conduction with <25°C case-to-ambient rise. Reverse leakage remains ≤18 µA at 100 V and 125°C - critical for standby efficiency in offline SMPS designs.

FAQ

What is the maximum allowable case temperature for continuous 10 A operation?

The SDT10100P5 supports 10 A average forward current up to +105°C case temperature when mounted on a 2"×2" aluminum board (RθJC = 3°C/W). At higher case temperatures, current must be derated per Figure 4 in DS40629 - e.g., 7.5 A at TC = +125°C. Thermal design must ensure TJ does not exceed +150°C.

Is the SDT10100P5 suitable for synchronous rectification in a 500 kHz buck converter?

No - the SDT10100P5 is a passive Schottky rectifier, not a synchronous rectifier IC. However, it is well-suited as a freewheel diode in non-synchronous buck or flyback converters up to 300 kHz due to its soft switching behavior and low stored charge. For synchronous rectification, a dedicated gate driver + MOSFET pair is required.

Does the PowerDI5 package require special solder paste or reflow profile?

No - the SDT10100P5 uses matte tin annealed terminals compliant with MIL-STD-202 Method 208 and is qualified for standard lead-free reflow profiles (peak 260°C, 60 sec max). Its PowerDI5 footprint matches IPC-7351B recommendations; recommended pad layout is provided in Diodes' package outline document PN-000011.

How does reverse leakage compare at 125°C versus 25°C?

At VR = 100 V, IR is 5 µA typical and 18 µA max at +125°C - just over twice the 3 µA typical / 80 µA max at +25°C. This tightly controlled high-temperature leakage ensures predictable standby power consumption in hot environments, unlike many older Schottky diodes that exhibit exponential IR increase above 100°C.
