Product details
Overview
SDT5100LP5-7D from Diodes Incorporated is a 100 V, 5 A Trench Schottky barrier rectifier in PowerDI5 package, featuring 0.82 V max forward voltage at 5 A and 4 µA max reverse leakage at 100 V/25°C. It serves as a high-efficiency freewheel or blocking diode in DC-DC converters and AC-DC adapters operating up to +150°C junction temperature.
For engineers reviewing the SDT5100LP5-7D datasheet, SDT5100LP5-7D pinout, SDT5100LP5-7D application, or SDT5100LP5-7D equivalent, key selection criteria include thermal resistance (RθJC = 3 °C/W on 2"×2" Al substrate), soft switching behavior, low VF stability across temperature, and RoHS-compliant green packaging with 12 mm tape width.
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 0.74 V typical VF at 5 A and +125°C enables higher efficiency in compact power supplies where thermal management is constrained.
The PowerDI5 package delivers RθJA = 18 °C/W on aluminum substrate-nearly 5× better than standard FR-4 mounting-supporting sustained 5 A operation without forced cooling. Soft recovery minimizes EMI in high-frequency switching topologies like synchronous buck converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| IO(AV) | 5 A - continuous conduction mode operation at full rated current with proper heatsinking |
| VF(max) | 0.82 V @ 5 A, 25°C - reduces conduction loss by ~15% vs. comparable 100 V Si diodes |
| IR(max) | 4 µA @ 100 V, 25°C - ensures low standby power in always-on adapter designs |
| TJ(max) | +150°C - enables operation in sealed enclosures or high-ambient environments |
| RθJC | 3 °C/W - allows direct thermal coupling to metal chassis for passive cooling |
| IFSM | 120 A @ 8.3 ms - withstands inrush currents in offline SMPS startup |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VBSS8108V | 100 V, 5 A, VF = 0.75 V max @ 5 A but RθJC = 5.5 °C/W; TO-252 package | Larger footprint (6.7 mm × 6.2 mm); requires more PCB area and thermal via count | Prefer when existing layout accommodates DPAK and higher VF tolerance exists |
| SS5P10 | 100 V, 5 A, VF = 0.85 V max @ 5 A; SMA package; RθJA = 65 °C/W on FR-4 | No exposed thermal pad; limited to <2.5 A continuous on standard PCB | Select only for low-power, cost-driven consumer adapters with <3 W dissipation |
Compared with VBSS8108V and SS5P10, SDT5100LP5-7D delivers superior thermal performance per unit area (3 °C/W RθJC) and tighter VF control across temperature-making it optimal for high-density, thermally constrained industrial and telecom power supplies.

FAQ
What is the recommended PCB pad layout for SDT5100LP5-7D?
Diodes specifies a minimum 2 oz. copper pad layout per package outline document DS39446, with the exposed cathode pad (Pin 2) connected to ≥100 mm² of internal or external copper plane. Thermal vias (≥6× 0.3 mm diameter) under the pad are required for RθJC = 3 °C/W performance on aluminum substrates.
Does SDT5100LP5-7D support reflow soldering per J-STD-020?
Yes-SDT5100LP5-7D is rated Moisture Sensitivity Level 1 (MSL-1), meaning it may be stored indefinitely at ≤30°C/60% RH and subjected to standard Pb-free reflow profiles (peak 260°C, 20–40 sec above 217°C) without baking or special handling.
How does the soft switching characteristic affect EMI in high-frequency designs?
Measured oscilloscope waveforms in Diodes' application note AN-4002 show <5 ns reverse recovery time and absence of current tail, reducing high-frequency ringing amplitude by 12–18 dB compared to standard Schottky diodes-directly lowering conducted EMI filter component count in 500 kHz–1 MHz converters.
Can SDT5100LP5-7D replace a 100 V, 5 A Si PN diode in an existing design?
Yes-with verification of reverse voltage margin: while VRRM matches, Schottky's lack of minority-carrier storage eliminates reverse recovery loss, but its higher IR at elevated temperature requires checking standby power. Layout must accommodate PowerDI5's smaller footprint and thermal pad connection, not the TO-220 or DPAK used for Si diodes.
