Product details
Overview
SBR10H300D1-13 from Diodes Incorporated is a 10A Super Barrier Rectifier (SBR®) in TO252 (DPAK) package, rated for 300V peak repetitive reverse voltage, with max forward voltage of 0.92V at 10A/25°C and leakage current ≤10µA at 300V/25°C. It serves as a high-efficiency polarity protection, boost, or blocking diode in DC-DC converters and industrial power supplies.
For engineers reviewing the SBR10H300D1-13 datasheet, SBR10H300D1-13 pinout, SBR10H300D1-13 application, or SBR10H300D1-13 equivalent, key selection criteria include low VF stability over temperature, 175°C max junction rating, TO252 thermal resistance of 2°C/W, and compliance with RoHS 3 and halogen-free "Green" standards.
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 capability and superior high-temperature leakage performance. Its structure enables stable operation up to 175°C junction temperature with minimal VF drift.
The device is optimized for unidirectional power conversion in switching topologies-specifically as a freewheeling diode in buck-derived converters or as a boost diode in PFC stages-where low conduction loss and robust thermal behavior under sustained load are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - Withstands up to 300V reverse bias without breakdown; suitable for 24–48V input systems with margin. |
| IO (AV) | 10 A - Continuous average forward current at TC = 110°C; derates linearly to zero at 175°C case temperature. |
| VF (MAX) | 0.92 V @ 10A, 25°C - Low conduction loss reduces power dissipation by ~15% vs. comparable Schottkys at same current. |
| IR (MAX) | 10 µA @ 300V, 25°C - Ultra-low leakage preserves efficiency in high-impedance blocking applications. |
| RθJC | 2 °C/W - Enables direct heatsink mounting for high-power density designs without additional thermal interface layers. |
| TJ Range | −55°C to +175°C - Supports operation in harsh environments including automotive under-hood and industrial motor drives. |
Pinout & Package
TO252 (DPAK) surface-mount package with exposed drain pad for thermal enhancement; 3-terminal configuration: Anode, Cathode, and Drain tab (electrically connected to cathode).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Lead 1) | Input terminal for forward conduction | Connected to source side in blocking or freewheeling paths; requires PCB trace capable of 10A continuous current. |
| Cathode (Lead 2) | Output terminal for forward conduction | Internally tied to exposed drain pad; must be soldered to large copper pour for thermal management. |
| Drain Tab (Exposed Pad) | Cathode connection / thermal path | Primary heat transfer interface; accounts for >80% of total thermal dissipation; requires ≥250 mm² 2oz Cu pad. |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Combines Schottky-like VF with PN-junction-level VRRM and leakage control-enables 300V operation without compromising efficiency. |
| Low VF at high temperature | VF = 0.78V @ 10A, 125°C-maintains <10% increase over 25°C value, reducing thermal runaway risk in compact layouts. |
| Halogen- and antimony-free "Green" construction | <900ppm Br, <900ppm Cl, <1000ppm Sb-meets strict environmental compliance for export and OEM sustainability programs. |
| UL 94V-0 molded plastic case | Self-extinguishing housing withstands reflow and long-term thermal cycling without cracking or outgassing. |
Applications
| DC-DC Converter Freewheeling Diode | Industrial Polarity Protection |
|---|---|

IC Role / Device Role / Timing Role: Output rectifier handling continuous 10A DC current with high-frequency switching ripple. Use Value: Low IR (≤10µA) prevents reverse conduction losses during PWM off-time, preserving regulation accuracy under light loads. |
Use Scenario: Mounted across brushed DC motor terminals in automated gate actuators to clamp inductive kickback. IC Role / Device Role / Timing Role: Snubber diode clamping flyback voltage spikes during MOSFET turn-off. Use Value: 110A IFSM rating absorbs single-pulse energy from 200W motors; TO252 thermal design sustains repeated surge events without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-10EWH03-M3 | Same 300V VRRM and 10A IO, but VF = 0.85V @ 10A/25°C; RθJC = 2.5°C/W; no halogen-free certification. | Better VF at room temp, but higher thermal resistance limits power density in space-constrained designs. | Prefer when absolute lowest VF at 25°C is prioritized over thermal performance or environmental compliance. |
| ON Semiconductor SBRA10300 | Identical 300V/10A rating, VF = 0.90V @ 10A/25°C, RθJC = 2.2°C/W, RoHS 3 compliant but not halogen-free. | Slightly better thermal resistance than SBR10H300D1-13, yet lacks "Green" compound specification. | Choose when supply chain diversification is needed and halogen-free requirement is waived by end-customer. |
Compared with VS-10EWH03-M3 and SBRA10300, the SBR10H300D1-13 delivers the lowest thermal resistance (2°C/W), guaranteed halogen-free construction, and best high-temperature VF stability-making it optimal for thermally demanding, environmentally regulated industrial deployments.

Manufacturer
Diodes Incorporated is a global manufacturer of discrete semiconductors and analog ICs, headquartered in Plano, Texas, with design, manufacturing, and sales operations across Asia, Europe, and North America.

FAQ
What is the maximum allowable case temperature for continuous 10A operation?
The SBR10H300D1-13 supports 10A average forward current only up to TC = 110°C, as shown in Figure 3 of the datasheet. Beyond this, current must be linearly derated to zero at 175°C. Operation above 110°C at full 10A violates the SOA and risks thermal runaway due to VF reduction and IR increase.
Is the exposed drain pad electrically isolated from the cathode?
No-the exposed drain tab is internally bonded to the cathode (Lead 2). This is confirmed in the mechanical data section and package marking diagram: both Lead 2 and the tab carry identical cathode potential and must be connected to the same net on the PCB for proper thermal and electrical function.
Does this part meet AEC-Q101 requirements for automotive use?
No-the SBR10H300D1-13 is not qualified to AEC-Q101. The datasheet explicitly states that automotive-grade versions require separate qualification (PPAP, IATF 16949 manufacturing, AEC-Q100/101/200 testing); this variant is intended for commercial and industrial applications only.
Can this diode replace a standard Schottky rectifier in an existing 300V design?
Yes-if the original Schottky had ≤300V VRRM and ≥10A IO rating-but verify layout compatibility: the TO252 footprint and thermal pad requirements differ significantly from common SMB/SMA packages. Also confirm that system-level leakage tolerance accommodates the SBR's 10µA IR at 300V/25°C.
