Product details
Overview
SDT10H50P5-7D from Diodes Incorporated is a 10A, 50V Trench Schottky barrier rectifier in PowerDI5 package, featuring VF ≤ 0.45 V at 10 A and IR ≤ 0.30 mA at 50 V and +125°C. It delivers soft fast switching, +150°C junction operation, and low thermal resistance (RθJC = 3°C/W with heatsink), enabling high-efficiency DC/DC converter output rectification.
For engineers reviewing the SDT10H50P5-7D datasheet, SDT10H50P5-7D pinout, SDT10H50P5-7D application, or SDT10H50P5-7D equivalent, key selection criteria include forward voltage drop at full load, high-temperature leakage stability, thermal performance on FR-4 vs. heatsink, and compatibility with 12 mm tape/7-inch reel logistics.
Technical Context
This Schottky rectifier uses trench MOS structure to reduce series resistance and enhance carrier injection efficiency, achieving sub-0.45 V VF at 10 A while maintaining low reverse recovery charge (Qrr) and soft recovery waveform. Its design targets high-frequency switching topologies where conduction loss dominates.
The PowerDI5 package integrates a thermally optimized copper clip leadframe with exposed die attach pad, enabling RθJA of 25°C/W when mounted on a 2"×2" aluminum heatsink - critical for compact, fanless power supplies operating up to +125°C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 50 V - Maximum blocking voltage before avalanche; ensures safe operation in 36 V nominal DC/DC outputs with margin. |
| IO(AV) | 10 A - Continuous average forward current at TA = +25°C with recommended PCB layout; derates to ~6.5 A at +85°C ambient. |
| VF @ 10 A | 0.45 V max at +25°C, 0.40 V max at +125°C - Directly reduces conduction loss by >30% vs. standard silicon diodes in 12 V–48 V systems. |
| IR @ 50 V | 0.30 mA max at +125°C - Enables stable operation in high-temp industrial adapters without thermal runaway risk. |
| RθJC | 3°C/W - With heatsink mounting, allows 3.3 W dissipation at ΔT = 10°C rise; supports compact thermal design without forced air. |
| TJ(max) | +150°C - Rated junction temperature enables use in sealed enclosures or under-hood automotive auxiliary supplies. |
| IFSM | 320 A (8.3 ms) - Withstands inrush currents in AC/DC adapters during cold start without degradation. |
Pinout & Package
Package: PowerDI5 - surface-mount, thermally enhanced 3-pin package with exposed thermal pad (Pin 2), molded green compound (UL 94V-0), and matte tin-plated leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Main current entry point; bonded directly to die anode region; requires low-inductance trace routing for EMI control. |
| Pin 2 | Cathode / Thermal Pad | Primary cathode connection and thermal path to PCB; must be soldered to ≥1 cm² copper pour for RθJA = 25°C/W. |
| Pin 3 | Anode | Second anode terminal; paralleled internally with Pin 1 to halve effective series resistance and improve current sharing. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF by 15–20% vs. planar Schottky at 10 A, lowering conduction loss in high-current buck outputs. |
| Soft, fast switching | Low Qrr and absence of minority-carrier storage minimizes voltage overshoot and EMI in 300–1000 kHz converters. |
| +150°C rated junction | Enables operation in sealed industrial power modules where internal ambient exceeds +100°C without derating. |
| Lead-free, halogen-free "Green" construction | Complies with RoHS 3 and JEDEC J-STD-020 Level 3 moisture sensitivity; suitable for automated reflow without popcorning. |
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 V10P5-M3/86A | Same 50 V/10 A rating but VF = 0.52 V max at 10 A; RθJC = 4.5°C/W; PowerPAK SO-8 package. | Higher VF increases conduction loss by ~0.7 W at 10 A; larger footprint limits board space savings. | Prefer SDT10H50P5-7D when thermal density or low VF is prioritized over package familiarity. |
| ON Semiconductor SB1050-TB | 50 V/10 A, VF = 0.50 V max at 10 A; TO-277 package; RθJA = 40°C/W on FR-4 (no heatsink). | Lacks exposed thermal pad; unsuitable for >7 A continuous operation without heatsink; higher thermal resistance. | Choose SDT10H50P5-7D for designs requiring >8 A in compact SMT layout with passive cooling only. |
Compared with V10P5-M3/86A and SB1050-TB, SDT10H50P5-7D offers the lowest VF and best thermal performance per mm², making it optimal for space-constrained, high-efficiency 10 A rectification where junction temperature control is critical.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The SDT10H50P5-7D is rated for continuous operation up to +150°C junction temperature. Derating curves in the datasheet show that at +125°C ambient with a 2"×2" aluminum heatsink, it sustains 10 A average current. Exceeding TJ(max) risks irreversible parametric shift and accelerated wear-out.
Can SDT10H50P5-7D replace a standard silicon rectifier in an existing 50 V design?
Yes - its 50 V VRRM matches common 1N5822-class replacements, and VF is ~40% lower at 10 A. However, ensure layout accommodates PowerDI5's 3-pin configuration and thermal pad soldering; reverse leakage is higher than silicon but remains stable up to +125°C.
Is the PowerDI5 package compatible with standard reflow profiles?
Yes - the device meets JEDEC J-STD-020 Level 3 moisture sensitivity and is qualified for Pb-free reflow with peak temperatures up to 260°C. Matte tin plating ensures reliable wetting; recommended soak time is 60–90 seconds at 150–200°C prior to ramp-up.
Does SDT10H50P5-7D meet AEC-Q101 for automotive use?
No - this part is not AEC-Q101 qualified. Diodes offers automotive-grade variants (e.g., SDT10H50P5Q-7D) with PPAP documentation and IATF 16949 manufacturing. For non-safety-critical body electronics, qualification may be pursued via customer-specific testing, but standard SDT10H50P5-7D lacks automotive change control.
