Diodes Incorporated SDT5H100LP5-13D

Overview

SDT5H100LP5-13D from Diodes Incorporated is a 100 V, 5 A trench Schottky barrier rectifier in PowerDI5 package, featuring 0.66 V max forward voltage at 5 A/25°C and 3.5 µA max reverse leakage at 100 V/25°C. It serves as a high-efficiency freewheel, blocking, or output rectifier in compact DC-DC converters and AC-DC adapters.

For engineers reviewing the SDT5H100LP5-13D datasheet, SDT5H100LP5-13D pinout, SDT5H100LP5-13D application, or SDT5H100LP5-13D equivalent, key selection criteria include thermal resistance (18 °C/W with heatsink), high-temperature IR stability (4.5 µA @ 125°C), soft switching behavior, and RoHS-compliant green packaging.

Technical Context

This Schottky rectifier uses trench MOS structure to achieve low VF and reduced reverse recovery charge, enabling high-frequency operation without snubbers. Its junction-to-ambient thermal resistance is 88 °C/W on standard FR-4 and drops to 18 °C/W with a 50 mm × 50 mm × 23 mm aluminum heatsink.

The device maintains stable leakage current up to +150°C operating temperature and exhibits soft reverse recovery characteristics critical for EMI-sensitive power supplies. It is rated for non-repetitive surge current of 150 A (8.3 ms sine half-wave), supporting robust transient handling in adapter front-ends.

FAQ

What is the thermal performance difference between PowerDI5 on FR-4 vs. aluminum substrate?

On standard 2 oz. FR-4 PCB, RθJA is 88 °C/W, limiting continuous power to ~0.7 W at +70°C ambient. With a 50 mm × 50 mm × 23 mm aluminum heatsink, RθJA improves to 18 °C/W, enabling 3.3 W dissipation at the same ambient-critical for unventilated enclosures.

Does SDT5H100LP5-13D require a heatsink in 5 A continuous operation?

Yes-continuous 5 A operation at TA = +70°C requires thermal management. At 5 A and 0.61 V VF (125°C), power dissipation is ~3.05 W. With RθJA = 18 °C/W, junction temperature would reach ~126°C-within spec but near limit; a heatsink ensures margin and reliability.

How does its soft switching behavior reduce EMI in high-frequency converters?

The trench Schottky structure eliminates minority-carrier storage, resulting in near-zero reverse recovery charge (Qrr). This prevents high di/dt-induced voltage spikes during turn-off, reducing broadband noise above 30 MHz and easing compliance with CISPR-32 Class B conducted emissions limits.

Is SDT5H100LP5-13D pin-compatible with other PowerDI5 Schottky rectifiers?

Yes-PowerDI5 is a standardized 2-pin package with anode and cathode terminals in fixed positions. All PowerDI5 Schottky rectifiers (e.g., SDT3H100LP5, SDT7H100LP5) share identical footprint, pad layout, and thermal pad geometry per Diodes' package outline DS-0001.
