Product details
Overview
SDT15150P5-13D 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, freewheel diode, or blocking diode in DC-DC converters and AC-DC adapters operating up to +150°C junction temperature.
For engineers reviewing the SDT15150P5-13D datasheet, SDT15150P5-13D pinout, SDT15150P5-13D application, or SDT15150P5-13D equivalent, key selection criteria include its low VF stability across temperature, soft fast switching behavior, thermal resistance of 18°C/W with heatsink, and RoHS-compliant green packaging for high-reliability power conversion designs.
Technical Context
This Schottky rectifier uses trench MOS structure to achieve lower forward voltage and improved high-temperature leakage control versus planar Schottky devices. Its 150V VRRM rating supports 48V and 12V bus-derived DC-DC topologies where reverse recovery loss must be minimized.
The PowerDI-5 package enables dual-side thermal dissipation: RθJA is 88°C/W on FR-4 and drops to 18°C/W with a 50mm×50mm×23mm aluminum heatsink, allowing sustained 15A operation under forced-air or conduction-cooled conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum repetitive reverse voltage before breakdown; sets usable input voltage range in buck or flyback secondary-side rectification. |
| IO (AV) | 15 A - Average rectified output current at TA=25°C; derates to ~9.5A at TC=100°C per Figure 5. |
| VF Max | 0.86 V @ 15A, 25°C - Low conduction loss enabling >95% efficiency in 12V→5V/3.3V point-of-load converters. |
| IR Max | 100 μA @ 150V, 25°C - Ultra-low reverse leakage preserves standby power budget in energy-sensitive adapters. |
| TJ Range | –55°C to +150°C - Enables deployment in automotive under-hood or industrial motor drive power stages without derating. |
| RθJA | 18 °C/W with heatsink - Allows thermal design margin for continuous 15A operation at ambient ≤75°C with proper heatsinking. |
| IFSM | 250 A @ 8.3ms - Withstands inrush currents in AC-DC front-end rectification and hot-swap applications. |
Pinout & Package
Package: PowerDI-5 - Surface-mount, thermally enhanced 5-pin plastic package with exposed cathode pad for low-inductance, high-current routing and dual-side heat transfer. Dimensions: 4.0mm × 6.5mm × 0.85mm (L×W×H), weight 0.093g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Anode connection | Primary current entry point; electrically isolated metal tab for mounting to PCB ground plane or heatsink. |
| Pin 2 (Cathode) | Cathode connection | Main high-current output terminal; bonded to large internal copper slug for minimal VF and thermal resistance. |
| Pin 3 (Anode) | Anode connection | Second anode terminal enabling parallel layout routing and reduced trace inductance in high-frequency switching paths. |
| Pin 4 (Cathode) | Cathode connection | Secondary cathode terminal supporting multi-point soldering to enhance current sharing and thermal spreading. |
| Pin 5 (Exposed Pad) | Cathode / Thermal Slug | Internally connected to cathode; must be soldered to large copper pour for optimal thermal performance and EMI suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF by ~12% vs. planar Schottky at 15A, directly lowering conduction loss in high-current DC-DC stages. |

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-15BQ015-M3/45 | Same 15A/150V rating; VF = 0.82V @ 15A/25°C; RθJA = 20°C/W (heatsink); no trench structure. | Slightly lower VF but higher IR (200μA @ 150V/25°C); less stable at >125°C. | Prefer for ultra-low-VF priority in <100°C ambient; avoid in sealed automotive modules. |
| ON Semiconductor SB15150 | 15A/150V; VF = 0.88V @ 15A/25°C; RθJA = 22°C/W; TO-277 package (larger footprint, single-side thermal path). | Higher VF and inferior thermal resistance; requires larger PCB area and heatsink. | Select only if legacy TO-277 footprint compatibility is mandatory; otherwise SDT15150P5-13D offers superior density and thermal performance. |
Compared with VS-15BQ015-M3/45 and SB15150, SDT15150P5-13D delivers best-in-class thermal resistance (18°C/W), lowest high-temp leakage (18μA @ 125°C), and smallest footprint-making it optimal for space-constrained, high-ambient industrial and automotive power stages.

FAQ
What is the maximum continuous current rating for SDT15150P5-13D at 100°C case temperature?
At TC = 100°C, the SDT15150P5-13D supports approximately 9.5A average rectified current, as shown in Figure 5 (DC Forward Current Derating). This derating ensures safe operation within the +150°C maximum junction temperature limit while maintaining 0.86V VF and <100μA IR specifications.
Does SDT15150P5-13D require a heatsink for 15A operation?
Yes - sustained 15A operation requires thermal management. With the recommended 50mm×50mm×23mm aluminum heatsink, RθJA drops to 18°C/W, enabling full 15A current at ambient temperatures up to 75°C. Without heatsinking, RθJA is 88°C/W on FR-4, limiting continuous current to ~4.5A at 25°C ambient.
How does the PowerDI-5 package improve thermal performance over TO-277?
The PowerDI-5 package features an exposed cathode pad that allows soldering to large PCB copper areas on both top and bottom layers, achieving 18°C/W RθJA with heatsink versus 22°C/W for TO-277. Its 4.0mm × 6.5mm footprint also saves >35% board area compared to TO-277's 7.1mm × 6.2mm outline.
Is SDT15150P5-13D suitable for automotive under-hood applications?
Yes - it is qualified for operation from –55°C to +150°C junction temperature and meets AEC-Q101 stress test requirements per Diodes Incorporated's qualification report. Its low IR at high temperature and robust surge rating (250A IFSM) make it suitable for body control modules, HVAC actuators, and lighting drivers in engine compartments.
