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 thermal resistance (18 °C/W with heatsink), soft fast switching behavior, high-temperature IR stability up to 125°C, and RoHS-compliant green packaging.
Technical Context
This Schottky rectifier uses trench MOS structure to achieve low VF and reduced reverse recovery charge. Its junction-to-ambient thermal resistance is 88 °C/W on FR-4 (2 oz Cu) and 18 °C/W with aluminum heatsink-enabling high-power-density designs without forced cooling.
It delivers stable reverse leakage (<20 µA at 100 V/125°C per Figure 3) and maintains VF <0.57 V at 5 A/125°C (typical), supporting reliable operation in thermally constrained industrial and adapter applications where silicon diodes would overheat.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Withstands continuous reverse blocking up to rated DC voltage without breakdown |
| IO (AV) | 5 A - Sustains average forward current under specified thermal conditions |
| VF (max) | 0.62 V @ 5 A, 25°C - Enables <3.1 W conduction loss at full load, reducing heat sink size |
| IR (max) | 0.1 mA @ 100 V, 25°C - Ensures minimal power loss in blocking state for high-efficiency topologies |
| RθJA | 18 °C/W with heatsink - Supports >2.8 W continuous dissipation at ΔT = 50°C ambient rise |
| IFSM | 150 A @ 8.3 ms - Handles transient surge currents common in SMPS startup and fault events |
| TJ Range | –55 to +150°C - Qualified for extended industrial temperature operation without derating |
Pinout & Package
Package: PowerDI5 - Surface-mount, thermally enhanced plastic package with exposed cathode pad; dimensions 3.966 mm × 6.51 mm × 1.10 mm; UL 94V-0 rated; moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Main current entry point; connects to input/source side of rectification path |
| Pin 2 | Cathode (Exposed Pad) | Primary current exit and thermal interface; soldered directly to PCB copper for low RθJA |
| Pin 3 | Anode | Second anode terminal-parallel-connected internally with Pin 1 for lower resistance and higher current sharing |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF by ~15% vs planar Schottky, enabling higher efficiency at 5 A load |
| Soft, fast switching | Negligible reverse recovery charge (Qrr ≈ 0 nC), eliminating snubber circuits in flyback/freewheel paths |
| High-temperature IR stability | Leakage remains <20 µA at 125°C - prevents thermal runaway in sealed enclosures |
| Green, halogen-free construction | Meets IEC 61249-2-21:2012; Br+Cl <1500 ppm, Sb <1000 ppm - compliant for automotive and medical end equipment |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS510-E3/57T (Vishay) | 100 V, 5 A, VF = 0.85 V @ 5 A - 37% higher conduction loss; TO-277 package | Larger footprint (6.7 × 4.2 mm); no exposed thermal pad - RθJA ≈ 60 °C/W | Choose only if legacy TO-277 layout reuse is required; avoid for thermally dense designs |
| MBR5H100FCT (ON Semiconductor) | 100 V, 5 A, VF = 0.65 V @ 5 A; same PowerDI5 package but 2-pin variant (no dual-anode) | No parallel anode terminals - limits current sharing and thermal spreading capability | Acceptable for lower-current derivatives (<4 A), but SDT5H100P5 preferred for full 5 A sustained loads |
Compared with SS510-E3/57T and MBR5H100FCT, SDT5H100P5 delivers lowest VF, best thermal performance via dual-anode + exposed cathode, and superior high-temperature leakage control-making it optimal for space-constrained, high-efficiency 5 A rectification.

FAQ
What is the maximum junction temperature rating for SDT5H100P5?
The SDT5H100P5 is rated for continuous operation from –55°C to +150°C junction temperature. This allows use in sealed industrial enclosures or high-ambient environments without derating below 5 A, provided thermal resistance is maintained per datasheet layout guidelines.
Does SDT5H100P5 require a heatsink for 5 A operation?
A heatsink is not mandatory but strongly recommended: at 5 A and 25°C ambient, junction temperature rises ~100°C with standard FR-4 layout (RθJA = 88 °C/W). Using the recommended 50 mm × 50 mm × 23 mm Al heatsink lowers RθJA to 18 °C/W, limiting ΔTJ to ~50°C - ensuring safe long-term operation.
How does the dual-anode configuration improve performance?
The dual-anode (Pins 1 and 3) reduces total series resistance by ~25% versus single-anode equivalents, lowering conduction loss and thermal stress. Combined with the exposed cathode pad (Pin 2), this enables more uniform current distribution and better heat spreading across the PCB copper area.
Is SDT5H100P5 suitable for automotive applications?
While SDT5H100P5 meets AEC-Q101 stress test requirements per Diodes' internal qualification, it is not officially AEC-Q101 certified. For automotive-grade use, Diodes recommends the AEC-Q101-qualified SDT5H100P5Q variant - identical electrical specs with added reliability testing and traceability.
