Diodes Incorporated SDT5H100LP5-7

Overview

SDT5H100LP5-7 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 or blocking diode in DC-DC converters and AC-DC adapters operating up to +150°C junction temperature.

For engineers reviewing the SDT5H100LP5-7 datasheet, SDT5H100LP5-7 pinout, SDT5H100LP5-7 application, or SDT5H100LP5-7 equivalent, key selection criteria include low VF stability across temperature, soft fast switching for EMI reduction, thermal resistance (18 °C/W with heatsink), and RoHS-compliant green packaging for industrial power supplies.

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 voltage overshoot during turn-off in inductive switching circuits.

The PowerDI5 package enables high power density with dual-side thermal dissipation: R_θJA = 88 °C/W on standard FR-4 (2 oz Cu) and 18 °C/W with aluminum heatsink, supporting compact 5 A rectification without forced air cooling.

Key Specifications

Pinout & Package

PowerDI5 is a surface-mount, thermally enhanced 2-pin package with exposed cathode pad for low-inductance, high-current routing and direct PCB thermal conduction. Cathode and anode terminals are on opposite edges of the molded body.

FAQ

What is the maximum junction temperature and how does it affect reliability?

The SDT5H100LP5-7 is rated for TJ = –55°C to +150°C. At 150°C, reverse leakage rises to 4.5 µA but remains stable without thermal runaway. This extended range enables use in sealed enclosures and under-hood automotive locations where ambient temperatures exceed 105°C, provided thermal design maintains TJ ≤ 150°C via proper PCB copper area or heatsinking.

Is the PowerDI5 package compatible with standard reflow profiles?

Yes-PowerDI5 is qualified for lead-free reflow per J-STD-020, with Moisture Sensitivity Level 1 (unlimited floor life). The package withstands peak temperatures up to 260°C for 30 seconds. Recommended profile follows IPC/JEDEC J-STD-020D: ramp-to-peak ≤ 3°C/s, time above 217°C = 60–150 s, peak = 235–245°C for optimal solder joint integrity and die attach reliability.

How does the soft switching behavior reduce EMI in DC-DC designs?

Soft switching refers to gradual reverse recovery with low dV/dt and minimal current tail. In buck converters, this suppresses high-frequency ringing at the switch node (typically 30–100 MHz), reducing conducted EMI by 5–8 dBµV and easing compliance with CISPR 22 Class B limits-eliminating need for ferrite beads or RC snubbers in many 300–500 kHz designs.

Can SDT5H100LP5-7 replace a 6 A Schottky in existing designs?

No-it is rated for 5 A average forward current. Derating to 6 A risks exceeding thermal limits: at 6 A and 85°C ambient, junction temperature exceeds 150°C even with heatsink (based on R_θJA = 18 °C/W). For 6 A applications, consider SDT6H100LP5-7 (6 A variant) or verify thermal margin using actual layout and airflow conditions before substitution.
