Product details
Overview
SDT15150VP5-7D from Diodes Incorporated is a 15A, 150V Trench Schottky barrier rectifier in PowerDI5 package, featuring 1.00 V max forward voltage at 15 A/25°C, 80 µA max reverse leakage at 150 V/125°C, and +150°C maximum junction temperature. It serves as a high-efficiency freewheel or blocking diode in DC-DC converters and AC-DC adapters where low conduction loss and thermal stability are critical.
For engineers reviewing the SDT15150VP5-7D datasheet, SDT15150VP5-7D pinout, SDT15150VP5-7D application, or SDT15150VP5-7D equivalent, key selection criteria include VF vs. temperature performance, RθJC of 3°C/W on heatsink, soft switching behavior, and PowerDI5's 0.093 g mass for board-level thermal management in space-constrained power supplies.
Technical Context
This Schottky rectifier uses trench MOS structure to reduce forward voltage while maintaining low IR drift up to +125°C - VF is 0.72 V at 15 A/125°C and IR rises only to 20 µA at 125°C under full 150 V bias. Its soft recovery minimizes EMI in high-frequency switching topologies.
The PowerDI5 package enables dual thermal paths: RθJA is 18°C/W with 2″×2″ Al board + 50mm×50mm×23mm heatsink, and RθJC is just 3°C/W - allowing direct case-to-heatsink mounting without soldered thermal vias for compact 15 A designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - blocks DC or peak AC voltages up to 150 V without breakdown |
| IO (AV) | 15 A - continuous average forward current rating at TC = 110°C per derating curve |
| VF Max | 1.00 V @ 15 A, 25°C - sets conduction loss floor; drops to 0.72 V at 125°C for improved efficiency at elevated temps |
| IR Max | 80 µA @ 150 V, 125°C - ensures minimal standby power loss in high-temp adapter applications |
| TJ Max | +150°C - supports operation in sealed enclosures or near hot components without derating |
| RθJC | 3°C/W - enables direct heatsink attachment for high-power density layouts without thermal vias |
| Package | PowerDI5 - surface-mount, thermally enhanced plastic package with matte tin terminals, RoHS/Green compliant |
Pinout & Package
PowerDI5 is a 2-terminal surface-mount package with anode and cathode leads exposed on opposite sides of the molded body. Thermal pad is electrically isolated and not connected to either terminal; case serves as cathode connection per standard marking diagram.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Forward current entry | Connected to input/high-side node in buck/flyback freewheel path; requires low-inductance trace routing |
| Cathode (Lead 2) | Forward current exit / common reference | Electrically tied to package case; must be routed to low-impedance ground or output return plane |
Key Features
| Feature | Design Value |
|---|---|
| Trench Schottky architecture | Reduces VF by ~15% vs. planar Schottky at 15 A, directly lowering I²R losses in 500 kHz+ DC-DC stages |
| Soft, fast switching | No reverse recovery charge (Qrr ≈ 0); eliminates snubber circuits and associated losses in synchronous rectification |
| +150°C operating junction | Enables placement adjacent to MOSFETs or transformers without external cooling in industrial adapters |
| PowerDI5 thermal resistance | RθJC = 3°C/W allows >12 W dissipation with <36°C rise above heatsink - sufficient for 15 A at 0.72 V VF |
Applications
| DC-DC Converter Output Rectification | AC-DC Adapter Secondary Side |
|---|---|
Use Scenario: High-frequency synchronous buck converter delivering 12 V/10 A to FPGA core rails. IC Role / Device Role / Timing Role: Freewheel diode replacing body diode of low-side MOSFET to reduce conduction loss and improve light-load efficiency. Use Value: 0.72 V VF at 125°C cuts conduction loss by 28% vs. standard Schottky, enabling >94% efficiency at full load without forced air. | Use Scenario: 24 V/3 A wall-mounted AC-DC adapter for industrial sensors. IC Role / Device Role / Timing Role: Output rectifier in flyback secondary, operating continuously at 65°C ambient inside sealed enclosure. Use Value: 20 µA IR at 125°C prevents >0.3 mW standby loss increase over temperature - critical for Energy Star Level VI compliance. |
| High-Temperature Motor Drive Snubber | Telecom DC Power Distribution |
Use Scenario: 48 V motor control board mounted near heat-generating IGBTs, ambient up to 95°C. IC Role / Device Role / Timing Role: Blocking diode isolating auxiliary 12 V rail from main bus during fault conditions. Use Value: Stable 150 V VRRM and 15 A IO rating maintained at TJ = 150°C ensures fail-safe isolation without derating. | Use Scenario: -48 V telecom shelf power system with distributed point-of-load converters. IC Role / Device Role / Timing Role: OR-ing diode in redundant 48 V input stage, conducting 8 A continuously. Use Value: PowerDI5's 3°C/W RθJC enables direct heatsink mounting - achieves <55°C case rise at 8 A, avoiding airflow dependency. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay V15P15-M3/86A | Same 150 V/15 A rating; VF = 0.82 V @ 15 A/25°C; RθJC = 4.5°C/W; TO-277 package | TO-277 has larger footprint and higher RθJC - less suitable for ultra-thin or heatsink-integrated layouts | Select when legacy TO-277 footprint compatibility is required and thermal margin exceeds 10°C |
| ON Semiconductor SB15150 | 150 V/15 A; VF = 0.95 V @ 15 A/25°C; RθJC = 5.0°C/W; DPAK package | DPAK requires more PCB area and offers inferior thermal coupling - limits power density in compact adapters | Choose if existing DPAK reflow profile or inventory simplification outweighs 0.05 V VF and 2°C/W thermal advantage |
Compared with V15P15-M3/86A and SB15150, SDT15150VP5-7D delivers the lowest VF at high temperature and best thermal resistance in the smallest footprint - making it optimal for next-gen 10–15 A power modules where board space and thermal headroom are constrained.

FAQ
What is the maximum allowable case temperature for continuous 15 A operation?
The SDT15150VP5-7D supports 15 A average forward current up to TC = 110°C per Figure 5 derating curve. At TC = 110°C, junction temperature remains within the +150°C limit assuming RθJC = 3°C/W - resulting in TJ = 110°C + (15 A × 0.72 V × 3°C/W) ≈ 142°C, providing 8°C safety margin.
Is the PowerDI5 package lead-free and RoHS compliant?
Yes. SDT15150VP5-7D features matte tin-plated copper leads, conforms to EU RoHS 2011/65/EU and RoHS 3 2015/863/EU directives, and is halogen- and antimony-free per Diodes' "Green" definition (<900 ppm Br, <900 ppm Cl, <1000 ppm Sb).
Does this device have a specified reverse recovery time (trr)?
No - as a Schottky barrier rectifier, SDT15150VP5-7D exhibits no minority-carrier storage and therefore has no defined trr. Its switching is governed by junction capacitance (CT ≈ 1000 pF at 0 V), enabling clean, low-EMI turn-off essential for >300 kHz switching frequencies.
Can SDT15150VP5-7D be used in automotive applications?
SDT15150VP5-7D is not AEC-Q101 qualified. For automotive use, Diodes offers the AEC-Q101-qualified SDT15150VP5Q-7D variant - identical electrical specs but manufactured in IATF 16949-certified facilities with PPAP documentation and controlled change management.
