Diodes Incorporated SDT10100P5-7D

Overview

SDT10100P5-7D from Diodes Incorporated is a 10A, 100V Trench Schottky Barrier Rectifier in PowerDI5 package, featuring VF ≤ 0.70 V at 10A/25°C, IR ≤ 80 µA at 100V/25°C, and TJ up to +150°C - deployed as freewheel or output rectifier in high-efficiency DC-DC converters and AC-DC adapters.

For engineers reviewing the SDT10100P5-7D datasheet, SDT10100P5-7D pinout, SDT10100P5-7D application, or SDT10100P5-7D equivalent, key selection criteria include forward voltage drop at full load, high-temperature leakage stability, thermal resistance (RθJC = 3°C/W on Al board), and compact PowerDI5 footprint for space-constrained power stages.

Technical Context

This Schottky rectifier uses trench MOS structure to achieve low VF and soft reverse recovery - critical for minimizing switching losses in synchronous buck and flyback topologies. Its RθJC of 3°C/W on 2"×2" aluminum board enables high-current operation without external heatsinking.

Designed for continuous conduction mode (CCM) and discontinuous conduction mode (DCM) operation, it maintains IR ≤ 18 µA at 100V/125°C and exhibits stable junction capacitance (CT ≈ 40 pF at VR = 4 V, f = 1 MHz), supporting predictable EMI behavior in high-frequency SMPS designs.

FAQ

What is the maximum allowable case temperature for continuous operation?

The SDT10100P5-7D supports continuous operation up to +150°C junction temperature. With RθJC = 3°C/W on a 2″×2″ aluminum board, the maximum sustainable case temperature at 10A is approximately +120°C - verified by Figure 4 derating curve showing IO = 10A at TC = 125°C. Exceeding this requires forced air or larger thermal mass.

Is the exposed pad electrically isolated or tied to a terminal?

The exposed pad on the PowerDI5 package is internally connected to the cathode (Pin 2) and must be soldered to a PCB copper area designated as cathode potential. It is not electrically isolated - using it as a floating thermal pad will cause short-circuit failure. Thermal vias to inner-layer ground planes are permitted only if those layers are also cathode-referenced.

How does leakage current change at elevated temperatures?

IR increases predictably with temperature: 5 µA at 100V/25°C, 18 µA at 100V/125°C, and ≤80 µA at 100V/25°C (max spec). Figure 3 confirms sub-100 µA behavior up to 150°C - critical for low-standby-power designs. No thermal runaway occurs due to Schottky barrier physics and trench structure stability.

Can SDT10100P5-7D replace a standard PN rectifier in existing designs?

Yes - as a direct drop-in replacement for 100V/10A PN rectifiers (e.g., 1N5408), provided layout accommodates PowerDI5's 4.0 × 6.5 mm outline and cathode pad soldering. Key benefits include 40% lower VF (reducing heat by ~5W), zero reverse recovery charge (eliminating snubbers), and +150°C rating versus +125°C for most PN devices.
