Product details
Overview
SDT15H100P5 from Diodes Incorporated is a 15A, 100V Trench Schottky Barrier Rectifier in PowerDI5 package, featuring 0.66V max forward voltage at 15A/25°C, 250µA max reverse leakage at 100V/125°C, and 150°C maximum junction temperature - optimized for high-efficiency DC/DC converters and AC/DC adapters.
For engineers reviewing the SDT15H100P5 datasheet, SDT15H100P5 pinout, SDT15H100P5 application, or SDT15H100P5 equivalent, key selection criteria include thermal resistance (RθJC = 3°C/W on heatsink), soft fast switching behavior, low VF stability across temperature, and PowerDI5's compact footprint with 0.093g mass for space-constrained power stages.
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 minimizes EMI in high-frequency switching topologies like synchronous buck and flyback converters.
Thermal performance is defined by two RθJA values: 90°C/W on standard FR-4 (2oz Cu) and 14°C/W on an aluminum heatsink substrate - enabling design flexibility between cost-sensitive PCB layouts and thermally demanding industrial applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - blocking capability for 48V input systems with 2× safety margin |
| IO(AV) | 15 A - continuous output current rating at TA = 25°C with derating above 25°C case temp |
| VF(MAX) | 0.66 V @ 15A, 25°C - reduces conduction loss by ~25% vs. comparable 100V Si diodes |
| IR(MAX) | 250 µA @ 100V, 125°C - ensures stable blocking in high-temp environments without thermal runaway |
| TJ(max) | +150°C - supports operation in sealed enclosures or high-ambient industrial power supplies |
| RθJC | 3°C/W - enables direct heatsink mounting for >10W dissipation without thermal throttling |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced plastic package with exposed cathode pad; dimensions: 4.05 × 6.60 × 1.15 mm (L × W × H); weight: 0.093 g; UL 94V-0 rated molding compound.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Main current entry point; connected to input rail or switch node in buck/flyback topologies |
| Pin 2 | Cathode (Exposed Pad) | Primary current exit + thermal path; must be soldered to large copper pour or heatsink for RθJC = 3°C/W |
| Pin 3 | Anode | Second anode terminal; paralleled internally with Pin 1 to reduce package inductance and resistive loss |
Key Features
| Feature | Design Value |
|---|---|
| Low VF with temperature stability | VF = 0.61 V @ 15A/125°C - maintains efficiency in hot-running adapters without derating |
| Soft, fast switching | Negligible reverse recovery charge (Qrr) - eliminates snubber circuits in 300–500 kHz converters |
| High-temperature leakage control | IR = 35 µA @ 100V/125°C - prevents standby power loss escalation in ambient >85°C |
| Green, RoHS-compliant construction | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb) - meets IEC 61249-2-21 and JEDEC J-STD-020 |
Applications
| Server VRM Output Stage | Industrial AC/DC Adapter |
|---|---|
Use Scenario: High-current, high-density 12V output stage in server voltage regulator modules operating at 300–600 kHz switching frequency. IC Role / Device Role / Timing Role: Synchronous rectifier freewheel diode replacing MOSFET body diode to reduce conduction loss and improve light-load efficiency. Use Value: 0.66V VF at 15A cuts conduction loss by 1.2W vs. Si diode, lowering thermal stress on adjacent controller ICs. |
Use Scenario: Secondary-side rectification in universal-input (90–264VAC) 48W industrial adapter with 75°C ambient requirement. IC Role / Device Role / Timing Role: Output rectifier in flyback topology, conducting during transformer reset phase with minimal reverse recovery noise. Use Value: Soft switching and 250µA IR at 125°C ensure no measurable standby power increase over product lifetime. |
| Telecom DC/DC Brick | Automotive Infotainment Power Supply |
Use Scenario: 48V-to-12V intermediate bus converter in telecom shelf power systems with forced-air cooling. IC Role / Device Role / Timing Role: Primary rectifier in half-bridge LLC resonant converter, handling 15A average current with peak surge tolerance up to 350A. Use Value: 350A IFSM rating allows safe handling of inrush and fault currents without bond-wire fusing. |
Use Scenario: 12V auxiliary supply rectifier in automotive infotainment head unit with under-hood ambient up to 105°C. IC Role / Device Role / Timing Role: Blocking diode isolating backup battery from main system rail during cold-crank events. Use Value: Stable 100V VRRM and +150°C TJ rating prevent breakdown during 16V load-dump transients and sustained high-temp operation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay V15PM10-M3/86A | Same 15A/100V rating but VF = 0.72V @ 15A/25°C; RθJC = 4.5°C/W; PowerPAK SO-8 package | Higher VF increases conduction loss by ~0.9W; larger footprint limits layout density | Prefer when existing SO-8 footprint reuse is required and thermal margin >5°C exists |
| ON Semiconductor SB15100 | 15A/100V; VF = 0.69V @ 15A/25°C; RθJC = 5.0°C/W; TO-277 package | TO-277 requires manual reflow or wave soldering; higher thermal resistance demands larger heatsink area | Choose only if legacy TO-277 assembly infrastructure is in place and board space permits |
Compared with V15PM10-M3/86A and SB15100, SDT15H100P5 delivers lowest VF and best thermal resistance in a fully automated SMT package - making it optimal for high-power-density, thermally constrained designs where conduction loss and layout area are critical.

FAQ
What is the recommended PCB pad layout for SDT15H100P5?
Diodes specifies a minimum 2oz copper pad layout per package outline document DS39646 - including a 5.3mm × 6.4mm exposed cathode pad connected to internal ground plane via ≥4 thermal vias (0.3mm diameter, 0.8mm pitch). This achieves the 14°C/W RθJA rating on heatsink substrates.
Does SDT15H100P5 support reflow soldering per J-STD-020?
Yes - SDT15H100P5 has Moisture Sensitivity Level 1 (MSL-1), meaning it can be stored indefinitely at ≤30°C/60% RH and withstand standard Pb-free reflow profiles (peak 260°C, 30 sec max) without baking or special handling.
How does SDT15H100P5 perform at 125°C junction temperature?
At TJ = 125°C, VF is 0.61V @ 15A and IR is 35µA @ 100V - confirming stable forward conduction and negligible leakage, critical for maintaining efficiency and reliability in sealed or high-ambient environments.
Can SDT15H100P5 replace a 15A Si fast recovery diode in an existing design?
Yes - with identical 100V VRRM and 15A IO rating, plus lower VF and zero reverse recovery time, SDT15H100P5 reduces both conduction and switching losses. Layout adaptation is required only for PowerDI5 footprint and thermal pad connection.
