Product details
Overview
SBR15300D1-13 from Diodes Incorporated is a 15A, 300V Super Barrier Rectifier (SBR®) in TO252 (DPAK) package, featuring 1.01V max forward voltage at 15A/25°C, 10µA max reverse leakage at 300V/25°C, and 2°C/W junction-to-case thermal resistance. It serves as a high-efficiency polarity protection, boost, or recirculating diode in DC-DC converters and industrial power supplies.
For engineers reviewing the SBR15300D1-13 datasheet, SBR15300D1-13 pinout, SBR15300D1-13 application, or SBR15300D1-13 equivalent, key selection criteria include forward voltage stability across temperature, surge current capability (110A IFSM), thermal performance under continuous conduction mode, and RoHS-compliant green packaging for surface-mount power rectification.
Technical Context
This SBR device uses patented Super Barrier Rectifier technology to achieve lower forward voltage than standard Schottky diodes while maintaining higher reverse voltage rating and superior high-temperature leakage performance. Its structure enables stable operation up to +175°C junction temperature with minimal VF drift.
The TO252 (DPAK) package provides low thermal resistance (2°C/W) and supports high-current PCB mounting without discrete heatsinks. It is rated for 15A average rectified output under standard 2″×2″ aluminum board conditions and requires 20% derating for capacitive loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - Maximum repetitive reverse blocking voltage; defines safe DC or peak AC voltage limit before breakdown. |
| IO | 15 A - Continuous average forward current at TC = 110°C; determines usable output power in regulated supplies. |
| VF (max) | 1.01 V @ 15A, 25°C - Directly impacts conduction loss and thermal design; drops to 0.92V at 125°C for improved efficiency at elevated temps. |
| IFSM | 110 A @ 8.3ms - Single half-sine surge rating; supports inrush current handling in PFC and motor drive front-ends. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance; enables accurate heatsink sizing when mounted on copper pour or external thermal pad. |
| IR (max) | 10 µA @ 300V, 25°C - Low leakage ensures minimal standby power loss in battery-backed or energy-sensitive systems. |
| TJ Range | −55°C to +175°C - Wide operating junction temperature range supports under-hood automotive and industrial ambient environments. |
Pinout & Package
TO252 (DPAK) surface-mount package with three terminals: anode, cathode, and exposed thermal pad (cathode-connected). Molded plastic case meets UL 94V-0 flammability rating; matte tin–annealed copper leadframe ensures solderability per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Input terminal for forward conduction | Connected to input rail (e.g., boost converter switch node); must handle full load current and transient surges. |
| Cathode (Pin 2) | Output terminal for forward conduction | Connected to output bus or return path; electrically tied to exposed thermal pad for enhanced heat dissipation. |
| Thermal Pad (Pin 3) | Thermal and electrical connection | Exposed copper pad on underside; must be soldered to large PCB copper area for thermal management and low-inductance cathode return. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® Technology | Combines Schottky-like low VF with PN-junction-like high VRRM and low IR-enables 300V operation without compromising efficiency. |
| High-Temp VF Stability | VF increases only ~0.15V from 25°C to 125°C at 15A-reduces thermal runaway risk in compact, sealed enclosures. |
| Green Halogen/Antimony-Free | <900ppm Br, <900ppm Cl, <1000ppm Sb-meets strict environmental compliance for export and OEM sustainability programs. |
| Low RθJC (2°C/W) | Enables >12W continuous power dissipation with minimal case-to-ambient delta-T-supports high-density layout without forced air. |
Applications
| DC-DC Boost Converter | Polarity Protection Circuit |
|---|---|
Use Scenario: Used in non-isolated boost topology to step up 12V battery input to 24V/48V rail in telecom power modules. IC Role / Device Role / Timing Role: Output rectifier conducting during switch-off phase; handles continuous 15A output current with minimal conduction loss. Use Value: 1.01V VF reduces power loss by ~1.5W vs. comparable 300V Si diode-improving efficiency from 92% to 93.8% at full load. |
Use Scenario: Placed in series with main power input to prevent damage from reverse battery connection in industrial controllers. IC Role / Device Role / Timing Role: Unidirectional current gate; blocks reverse voltage up to 300V while passing forward current with low drop. Use Value: 10µA IR at 25°C ensures negligible standby drain-critical for long-life battery-powered edge sensors. |
| Motor Drive Recirculation Path | AC-DC Bridge Output Stage |
Use Scenario: Provides freewheeling path for inductive kickback in 48V BLDC motor gate drivers. IC Role / Device Role / Timing Role: Clamp diode across motor winding; conducts brief high-current pulses (110A IFSM) during PWM off-time. Use Value: Robust surge rating eliminates need for parallel diodes-simplifies layout and reduces BOM count in compact motor control boards. |
Use Scenario: Final rectification stage in offline SMPS with PFC pre-regulator feeding 300V DC bus. IC Role / Device Role / Timing Role: High-voltage output rectifier; blocks 300V reverse potential while delivering stable 15A DC output. Use Value: Stable VF over −55°C to +175°C ensures consistent regulation across automotive under-hood temperature swings. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-15EWH03-M3 | 300V VRRM, 15A IO, but VF = 1.15V @ 15A - 140mV higher than SBR15300D1-13 at 25°C. | Higher conduction loss limits use in thermally constrained 125°C ambient designs. | Prefer when legacy Vishay footprint compatibility is required and 0.14V VF penalty is acceptable. |
| ON Semiconductor NDS351AN | Not applicable - MOSFET-based ideal diode controller; requires external FET and gate drive circuitry. | Enables active OR-ing and ultra-low VF (<50mV), but adds complexity and cost. | Select only when dynamic control, reverse current blocking, or <50mV drop justifies added components and layout area. |
Compared with VS-15EWH03-M3, SBR15300D1-13 delivers lower conduction loss and better thermal stability; versus NDS351AN, it offers plug-and-play simplicity and lower system-level BOM cost for fixed-function rectification.

FAQ
What is the maximum allowable case temperature for continuous operation?
The SBR15300D1-13 supports continuous operation up to TC = 110°C per its DC forward current derating curve (Figure 3). At this case temperature, the rated average output current remains 15A. Exceeding 110°C requires linear derating to zero at 175°C junction temperature, assuming proper thermal interface and PCB copper area.
Is the thermal pad electrically isolated or connected internally?
The exposed thermal pad on the TO252 package is electrically connected to the cathode terminal (Pin 2), as confirmed by Diodes' mechanical drawings and internal construction. It must be soldered to a cathode-referenced copper pour-not left floating or tied to ground unless the cathode is grounded in the circuit.
How does leakage current change at elevated temperatures?
At TJ = +125°C and VR = 300V, IR rises to 1 mA (per datasheet Table "Electrical Characteristics"), representing a 100× increase over the 10 µA value at 25°C. This is typical for SBR devices and must be accounted for in high-temperature standby power budgets.
Can SBR15300D1-13 replace a standard 300V fast recovery diode?
Yes-its 1.01V VF at 15A is significantly lower than typical fast recovery diodes (1.7–2.2V), reducing conduction loss and heat generation. However, its reverse recovery behavior differs: SBR devices exhibit soft, low-noise recovery without tail current, making them preferable in EMI-sensitive switching applications.
