Product details
Overview
SDT5H100P5 from Diodes Incorporated is a 100 V, 5 A trench Schottky barrier rectifier in PowerDI5 package, featuring 0.62 V max forward voltage at 5 A and 0.1 mA max reverse leakage at 100 V/25°C. It serves as a high-efficiency freewheel or output rectifier in compact DC-DC converters and AC-DC adapters.
For engineers reviewing the SDT5H100P5 datasheet, SDT5H100P5 pinout, SDT5H100P5 application, or SDT5H100P5 equivalent, key selection criteria include low VF at high current, stable IR up to +125°C, thermal resistance of 18 °C/W with heatsink, and compatibility with space-constrained power stages requiring RoHS- and halogen-free compliance.
Technical Context
This Schottky rectifier uses trench MOS-based architecture to achieve lower forward voltage and reduced reverse recovery charge versus planar Schottkys. Its soft, fast switching behavior minimizes EMI in high-frequency switching topologies such as synchronous buck converters operating above 300 kHz.
The device is rated for continuous operation from –55°C to +150°C junction temperature, with reverse leakage tightly controlled (≤20 mA at 100 V/125°C), enabling reliable performance in thermally demanding environments like enclosed power adapters and industrial DC supplies.
Key Specifications

| IR (max) | 0.1 mA @ 100 V, 25°C - Ensures <0.1 W standby loss in high-impedance bias networks |
| RθJA | 18 °C/W - Achievable with 50 mm × 50 mm × 23 mm Al heatsink; enables 4.2 W dissipation at ΔT = 75°C |
| TJ Range | –55°C to +150°C - Supports operation in automotive under-hood or industrial ambient conditions |
| Capacitance | 1000 pF @ 4 V - Low junction capacitance maintains efficiency in >500 kHz switching applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VSS5100M3/H | Same 100 V/5 A rating; VF = 0.65 V @ 5 A; RθJA = 22 °C/W (FR-4); no halogen-free certification stated | Higher VF increases conduction loss by ~0.15 W; less suitable for thermally constrained adapters | Prefer SDT5H100P5 where RoHS 3 and thermal performance are mandatory |
| ON Semiconductor SB5100 | 100 V/5 A; VF = 0.75 V @ 5 A; IR = 0.5 mA @ 100 V/25°C; TO-277 package (larger footprint) | Higher VF and IR degrade efficiency and thermal margin; TO-277 requires more PCB area | SDT5H100P5 offers 15% smaller footprint and 21% lower VF-critical for miniaturized designs |
Compared with VSS5100M3/H and SB5100, SDT5H100P5 delivers the lowest VF, tightest IR control at high temperature, smallest PowerDI5 footprint, and verified halogen-free compliance-making it optimal for space- and efficiency-critical 5 A rectification.

FAQ
What is the maximum junction temperature for continuous operation?
The SDT5H100P5 is rated for continuous operation up to +150°C junction temperature. This rating is validated per JEDEC JESD22-A108 and confirmed in the datasheet's Thermal Characteristics table. Operation at this limit requires appropriate heatsinking and PCB copper area per the recommended 50 mm × 50 mm Al heatsink layout.
Is the PowerDI5 package lead-free and RoHS-compliant?
Yes. The SDT5H100P5 features a lead-free finish and complies with EU RoHS Directive 2015/863/EU (RoHS 3). Its molding compound is halogen- and antimony-free, with bromine <900 ppm, chlorine <900 ppm (total Br+Cl <1500 ppm), and antimony <1000 ppm, meeting Diodes Incorporated's "Green" definition.
How does the soft switching behavior reduce EMI in DC-DC designs?
Unlike conventional diodes, the SDT5H100P5 exhibits no reverse recovery charge (Qrr ≈ 0) due to its majority-carrier Schottky structure. This eliminates high di/dt-induced voltage spikes during turn-off, reducing broadband EMI by up to 10 dB in the 30–100 MHz range and relaxing filtering requirements in buck and flyback converters.
Can SDT5H100P5 replace a standard 1N5822 in existing designs?
No-direct replacement is not recommended. The 1N5822 is a DO-201AD-packaged 3 A Schottky (VF ≈ 0.9 V). SDT5H100P5 offers higher current (5 A), lower VF (0.62 V), and PowerDI5 footprint. Layout redesign and thermal validation are required; however, it enables higher efficiency and power density in upgraded versions of those designs.
