Product details
Overview
SBR2M100SAF-13 from Diodes Incorporated is a 2.0A surface-mount Super Barrier Rectifier (SBR®) in SMAF package, rated for 100V peak repetitive reverse voltage, with max forward voltage drop of 0.78V at 2A and reverse leakage current ≤1µA at 100V/25°C. It serves as a high-efficiency rectifier in DC-DC converters and polarity protection circuits where low VF and thermal stability are critical.
For engineers reviewing the SBR2M100SAF-13 datasheet, SBR2M100SAF-13 pinout, SBR2M100SAF-13 application, or SBR2M100SAF-13 equivalent, key selection criteria include its 65A non-repetitive surge rating, soft fast switching behavior, patented interlocking clip construction, and AEC-Q101 readiness for automotive-grade reliability validation.
Technical Context
This SBR rectifier employs Diodes' proprietary Super Barrier Rectifier technology to achieve lower forward voltage than standard Schottky diodes while maintaining superior reverse leakage performance at elevated temperatures up to +150°C. Its junction-to-lead thermal resistance is 45°C/W on FR-4 PCB, enabling efficient heat dissipation in compact power stages.
The device features cathode-band polarity marking, matte tin–annealed copper lead-frame terminals, and UL 94V-0 molded plastic case. It is qualified to JEDEC high-reliability standards and supports halogen/antimony-free "Green" compliance per <900ppm Br/Cl and <1000ppm Sb.

Applications
| DC-DC Converter | AC-DC Rectifier |
|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated flyback or forward converters delivering 5–24V outputs. IC Role / Device Role: Low-VF rectifier replacing MOSFETs or standard Schottkys to reduce conduction loss and simplify gate drive. Use Value: 0.78V VF at 2A lowers power loss by ~15% vs. typical 0.9V Schottky, improving light-load efficiency. | Use Scenario: Input bridge or output rectification stage in offline AC-DC adapters for consumer electronics. IC Role / Device Role: Discrete rectifier providing unidirectional current flow with stable leakage across temperature. Use Value: ≤1µA IR at 100V/25°C ensures negligible standby drain-critical for Energy Star-compliant designs. |
| Polarity Protection | Re-Circulating Diode |
Use Scenario: Reverse-voltage protection on 12V/24V board inputs in automotive control modules. IC Role / Device Role: Series-blocking diode placed before main regulator or microcontroller supply rail. Use Value: 100V VRRM accommodates load-dump transients; −55°C to +150°C rating matches vehicle under-hood conditions. | Use Scenario: Freewheeling path for inductive loads such as solenoids, relays, or motor windings in industrial PLC outputs. IC Role / Device Role: Clamp diode absorbing back-EMF energy during switch-off transitions. Use Value: Soft switching reduces voltage overshoot and RFI; 65A IFSM handles peak inductive kick without failure. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT2M100SAF-13 | Same SBR® die, but with enhanced surge rating (IFSM = 75A) and tighter VF distribution (0.72V typ) | Better suited for high-surge industrial motor drives where IFSM margin is critical | Select when >65A surge headroom is required without changing layout or thermal design |
| MBR2100F-TP | Standard Schottky rectifier; VF = 0.85V (max), IR = 100µA @ 100V/25°C - higher leakage and VF | Acceptable for cost-sensitive, non-automotive applications with relaxed thermal/leakage specs | Choose only if leakage and efficiency are secondary to BOM cost; not recommended for automotive or high-temp use |
Compared with SBRT2M100SAF-13, the SBR2M100SAF-13 offers adequate surge margin for most DC-DC and protection roles at lower cost; versus MBR2100F-TP, it delivers significantly lower leakage and VF-making it preferable for thermally constrained or battery-powered systems.

FAQ
What is the maximum operating temperature for SBR2M100SAF-13?
The SBR2M100SAF-13 has an operating junction temperature range of −55°C to +150°C. Its thermal resistance junction-to-lead is 45°C/W on a standard FR-4 PCB, allowing reliable operation at full 2.0A current up to +125°C ambient when properly mounted with adequate copper area.
Is SBR2M100SAF-13 suitable for automotive applications?
Yes-the device is qualified to JEDEC high-reliability standards referenced in AEC-Q101 and manufactured in IATF 16949 certified facilities. While the -13 suffix part itself is not AEC-Q101 certified, its process and test flow align with automotive requirements; the Q-suffix variant (e.g., SBR2M100SAFQ-13) is the fully qualified version.
How does SBR2M100SAF-13 differ from a standard Schottky diode?
Unlike conventional Schottky diodes, the SBR2M100SAF-13 uses patented Super Barrier Rectifier technology to achieve lower reverse leakage (<1µA vs. >100µA typical) at high temperature while retaining low forward voltage (~0.78V). This avoids thermal runaway and improves reliability in hot environments.
What is the recommended PCB pad layout for SMAF package?
Per Diodes' package outline DS43348, the SMAF pad layout requires a 0.2" × 0.25" (5.08 × 6.35 mm) copper pad per terminal on FR-4. The suggested dimensions are C = 4.00 mm, X = 2.50 mm, Y = 1.70 mm, and X1 = 6.50 mm. Full details are available at diodes.com/package-outlines.html.
