Product details
Overview
SBR10U300CT from Diodes Incorporated is a 10A, 300V ultra-low forward voltage super barrier rectifier in TO220AB package, featuring 0.71V typical VF at 10A/25°C, 25ns typical reverse recovery time, and 150A non-repetitive surge capability - optimized for high-efficiency AC/DC front-end and DC-DC secondary-side rectification in industrial power supplies.
For engineers reviewing the SBR10U300CT datasheet, SBR10U300CT pinout, SBR10U300CT application, or SBR10U300CT equivalent, key selection criteria include forward voltage trade-offs at elevated temperature, thermal resistance (2°C/W junction-to-case), soft-switching behavior under di/dt = 100A/μs, and RoHS-compliant "Green" packaging compliance per J-STD-020 Level 1.
Technical Context
This device implements Diodes Inc.'s patented SBR® technology to achieve lower VF than standard Schottky diodes while maintaining higher VRRM and superior high-temperature leakage stability. It replaces conventional Schottkys in 300V-class applications where IR must remain below 25mA at 125°C.
The rectifier operates as a unidirectional, single-phase, half-wave device with soft, fast switching (tRR ≤ 35ns) and is rated for continuous operation up to TJ = +175°C. Its TO220AB package enables direct heatsink mounting with 2°C/W thermal resistance, supporting high-current conduction without forced air cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 300 V - Maximum repetitive reverse blocking voltage; defines usable input range in offline SMPS designs. |
| IO @ TC=150°C | 10 A - Continuous average forward current at case temperature 150°C; sets minimum heatsink requirement. |
| VF @ 10A, 25°C | 0.71 V - Typical forward drop; reduces conduction loss by ~30% vs. comparable 300V Schottky diodes. |
| tRR | 25 ns - Typical reverse recovery time; enables clean switching in 100–500 kHz DC-DC converters. |
| RθJC | 2 °C/W - Junction-to-case thermal resistance (TO220AB); allows precise thermal design with standard aluminum heatsinks. |
| IR @ 300V, 125°C | 25 mA - Max reverse leakage at full rating and high temperature; ensures stable operation in hot environments. |
| IFSM | 150 A - Non-repetitive surge current (8.3ms half-sine); withstands inrush and transient overloads in AC line inputs. |
Pinout & Package
Package: TO220AB - Molded plastic case, UL 94V-0 rated, lead-free matte tin finish on copper leadframe, 1.85g weight. Designed for vertical mounting with tab isolation or heatsink attachment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Anode) | Anode connection | Primary current entry point; electrically isolated from tab in standard TO220AB configuration. |
| Pin 2 (Cathode) | Cathode connection | Current exit node; tied to metal tab in common-cathode dual-die variant (not applicable here - SBR10U300CT is single-die). |
| Tab (Cathode) | Cathode terminal / thermal path | Electrically connected to cathode; serves as primary heat dissipation surface; requires insulating washer if mounted to grounded heatsink. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF | 0.71V typ @ 10A/25°C - Reduces conduction loss by ≥0.7W vs. legacy 300V Schottkys at same current. |
| Soft switching | tRR ≤ 35ns with low IRR tail - Minimizes EMI and voltage overshoot during turn-off in hard-switched topologies. |
| High-temp stability | IR ≤ 25mA @ 300V/125°C - Maintains low leakage in enclosed industrial enclosures without derating. |
| RoHS + Green | Halogen- and antimony-free molding compound (<900ppm Br+Cl, <1000ppm Sb) - Complies with automotive and EU environmental mandates. |
Applications
| Server PSU Secondary Rectification | Industrial AC/DC Front-End |
|---|---|
Use Scenario: 12V/24V output stage in 80 PLUS Titanium server power supplies operating at 300–500 kHz.

IC Role / Device Role / Timing Role: High-reliability rectifier in safety-critical auxiliary rail feeding MCU and gate drivers. Use Value: -65°C to +175°C operating range and AEC-Q200-aligned construction ensure lifetime reliability under thermal cycling. |
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/10A rating; VF = 0.75V @ 10A/25°C; tRR = 32ns; TO220AC package (anode-tab isolated). | Higher VF increases conduction loss by ~0.3W; identical thermal resistance but different pinout (anode on tab). | Select when anode-isolated mounting is required; verify PCB layout compatibility with reversed terminal assignment. |
| ON Semiconductor MUR1030CT | Standard ultrafast rectifier; VF = 1.15V @ 10A/25°C; tRR = 60ns; higher switching loss and EMI. | Not suitable for high-frequency (>100 kHz) designs due to slow recovery and hard switching. | Use only in cost-sensitive, low-frequency (<60 Hz) rectification where efficiency is secondary to BOM cost. |
Compared with VS-10EWH03-M3 and MUR1030CT, SBR10U300CT delivers the lowest VF among 300V/10A rectifiers, enabling highest efficiency in compact, thermally constrained 200–500 kHz converters - while MUR1030CT's slower recovery limits use to line-frequency applications.

FAQ
Is SBR10U300CT pin-compatible with standard TO220AB Schottky diodes?
Yes - SBR10U300CT uses industry-standard TO220AB mechanical outline and terminal spacing (e.g., matching Vishay SS10P3, ON Semi SB1030). Pin 1 is anode, Pin 2 is cathode, and the metal tab is cathode-connected. No PCB redesign is needed for drop-in replacement in existing layouts.
What is the maximum recommended case temperature for continuous operation?
The datasheet specifies IO = 10A at TC = +150°C. Operation beyond this requires derating per Fig. 4: at TC = +160°C, max IO drops to ~8.5A; at TC = +175°C, it falls to ~6.2A. Thermal design must maintain TC ≤ 150°C under worst-case ambient and airflow conditions.
Does SBR10U300CT meet AEC-Q101 for automotive use?
No - SBR10U300CT is not AEC-Q101 qualified. Diodes Inc. offers the automotive-grade SBR10U300CTQ (with PPAP documentation and IATF 16949 manufacturing) for automotive applications. This standard version is intended for industrial, telecom, and computing end-equipment.
How does its reverse recovery compare to silicon carbide Schottkys?
SBR10U300CT has tRR = 25–35ns, significantly faster than standard Si fast rectifiers but slower than SiC Schottkys (typically <10ns). Unlike SiC devices, it requires no gate drive and operates with zero reverse recovery charge (QRR ≈ 0), eliminating snubber needs in most topologies.
