Product details
Overview
SDT15150P5 from Diodes Incorporated is a 15A, 150V Trench Schottky Barrier Rectifier in PowerDI-5 package, delivering 0.86V max forward voltage at 15A/25°C and 100μA max reverse leakage at 150V/25°C. It serves as a high-efficiency rectifier or freewheel diode in DC-DC converters and AC-DC adapters operating up to +150°C junction temperature.
For engineers reviewing the SDT15150P5 datasheet, SDT15150P5 pinout, SDT15150P5 application, or SDT15150P5 equivalent, this device offers verified thermal performance on Al heatsink (RθJA = 18°C/W), soft fast switching behavior, and RoHS-compliant green packaging-key selection criteria for high-density power supply designs requiring low conduction loss and stable high-temperature operation.
Technical Context
This Schottky rectifier uses trench MOS structure to achieve lower VF and reduced IR drift versus planar Schottkys. Its 150V VRRM rating supports 48V and 36V bus-derived converter topologies, while the 250A non-repetitive surge rating enables robust handling of transient inrush currents.
The PowerDI-5 package integrates dual anode/cathode terminals with exposed thermal pad, enabling direct mounting to PCB copper or heatsink. Thermal resistance drops from 88°C/W (FR-4) to 18°C/W (Al board + heatsink), confirming its suitability for thermally constrained industrial and adapter applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Blocks DC or peak AC voltages up to 150V without breakdown in rectifier or blocking roles. |
| IO (AV) | 15 A - Sustains continuous average forward current of 15A at TA = +25°C with proper heatsinking. |
| VF Max | 0.86 V @ 15A, 25°C - Limits conduction loss to ≤12.9W per diode in high-current paths. |
| IR Max | 100 μA @ 150V, 25°C - Ensures minimal standby power loss and stable bias in high-impedance circuits. |
| TJ Operating Range | –55°C to +150°C - Supports operation in sealed enclosures or under-hood environments without derating. |
| RθJA (Heatsink) | 18 °C/W - Enables 15A operation with ≤270°C total ΔT rise when mounted on specified Al heatsink. |
| IFSM | 250 A @ 8.3ms - Withstands typical input capacitor inrush surges in offline SMPS without failure. |
Pinout & Package
Package: PowerDI-5 - Surface-mount, thermally enhanced plastic package with exposed thermal pad and dual anode/cathode terminals. Dimensions: 4.0mm × 6.5mm × 0.85mm (L×W×H), weight ≈ 0.093g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (A1) | Input terminal for forward conduction path | One of two parallel anode connections; shares current with A2 to reduce effective series resistance. |
| Anode 2 (A2) | Input terminal for forward conduction path | Second anode terminal; enables symmetrical current distribution and improved thermal spreading across package. |
| Cathode (K) | Output terminal for forward conduction path | Single cathode node; carries full 15A output current and connects to ground or return rail. |
| Thermal Pad (EP) | Thermal interface to PCB/heatsink | Exposed copper pad beneath die; must be soldered to large copper area or heatsink for RθJA = 18°C/W performance. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-15EWH15-M3 | Same 150V/15A rating but TO-252 package; VF = 0.82V @ 15A/25°C; RθJA = 50°C/W (FR-4). | Larger footprint (6.7mm × 6.2mm); no exposed thermal pad; less efficient thermal transfer in compact layouts. | Prefer when legacy TO-252 layout exists and heatsinking is via ambient convection only. |
| ON Semiconductor SB15150 | 150V/15A in PowerFLAT 5x6; VF = 0.84V @ 15A/25°C; IR = 120μA @ 150V/25°C; RθJA = 25°C/W (Al board). | Higher IR increases standby loss in always-on systems; slightly larger footprint than PowerDI-5. | Choose if existing PowerFLAT 5x6 footprint requires drop-in replacement with minor IR trade-off. |
Compared with VS-15EWH15-M3 and SB15150, SDT15150P5 delivers superior thermal performance (18°C/W) in the smallest footprint (4.0×6.5mm), making it optimal for space-constrained, high-power-density applications where heatsink integration is feasible.

FAQ
What is the recommended minimum solder pad size for the PowerDI-5 thermal pad?
The datasheet specifies a suggested pad layout linked from diodes.com/package-outlines.html. For optimal thermal performance (RθJA = 18°C/W), the exposed thermal pad must connect to ≥250 mm² of 2oz copper on an aluminum-backed board with a 50mm × 50mm × 23mm heatsink. Smaller pads increase RθJA proportionally.
Does SDT15150P5 support bidirectional current flow?
No. As a Schottky barrier rectifier, SDT15150P5 conducts current only from anode to cathode. Reverse conduction is blocked above its 150V VRRM rating, and it is not rated for reverse-biased operation or synchronous rectification control.
How does IR change at elevated temperature, and what impact does it have on adapter standby loss?
IR rises to 18μA at 150V/125°C (per datasheet Table 3). In a 65W adapter with 100kΩ output divider, this adds only ~1.8mW of additional standby dissipation-well within Energy Star limits and negligible versus other system losses.
Can SDT15150P5 replace a standard PN-junction rectifier in an existing design?
Yes-if VRRM and IO ratings match and circuit topology allows zero-recovery behavior. Unlike PN diodes, SDT15150P5 has no reverse recovery charge (Qrr ≈ 0), eliminating switching loss and EMI. However, its higher IR at low voltage (<20V) may require verification in low-VF-critical paths.
