Product details
Overview
SBR2A30P1-7 from Diodes Incorporated is a 2.0A surface-mount Super Barrier Rectifier with 30V peak repetitive reverse voltage, low forward voltage drop (0.23V at 0.1A, 25°C), ±16kV HBM ESD rating, and AEC-Q101 qualification for automotive power conversion. It operates up to 150°C junction temperature and delivers soft, fast switching in PowerDI®123 package.
For engineers reviewing the SBR2A30P1-7 datasheet, SBR2A30P1-7 pinout, SBR2A30P1-7 application, or SBR2A30P1-7 equivalent, key selection factors include its 75A non-repetitive surge capability, <50µA leakage at 5V/25°C, patented interlocking clip design, RoHS-compliant matte tin finish, and thermal resistance of 5°C/W (junction-to-soldering).
Technical Context
This Super Barrier Rectifier replaces Schottky diodes in high-efficiency DC/DC converters and automotive body electronics where low VF and high-temperature stability are critical. Its patented super barrier structure enables lower forward voltage than standard Schottkys while maintaining superior reverse avalanche ruggedness and reduced leakage versus conventional PN junctions.
The device uses a copper leadframe with annealed matte tin plating and is molded in halogen-free "green" compound rated UL 94V-0. Its PowerDI®123 package provides optimized thermal path to PCB via cathode tab, achieving 5°C/W RθJS when soldered per recommended pad layout on 2 oz. FR-4.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe operating range in 24V automotive systems. |
| IO(AV) | 2.0 A - Average forward current rating at 25°C ambient; derates to ~1.5A at 100°C per Fig.5. |
| VF @ 1A, 25°C | 0.34 V - Low conduction loss enabling >92% efficiency in 5V–12V buck converter outputs. |
| IFSM | 75 A - Single half-sine surge capacity supports load dump and cold-crank transients in automotive ECUs. |
| IR @ 30V, 25°C | 55 µA - Ultra-low leakage preserves battery standby time in always-on modules. |
| TJ max | 150 °C - Enables placement near heat sources (e.g., power MOSFETs) without derating penalties. |
| ESD Rating | ±16 kV HBM - Eliminates need for external ESD protection in infotainment and ADAS sensor interfaces. |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT2A30P1-7 | Same PowerDI®123 package and 30V rating, but higher VF (0.42V @ 1A) and lower IFSM (60A). | Less suitable for high-surge automotive loads; acceptable in industrial SMPS with lower transient stress. | Select only if cost sensitivity outweighs surge margin and efficiency requirements. |
| MBR230LSFT1G | 2A Schottky in SOD-123FL; VF = 0.45V @ 1A, no AEC-Q101, IR = 200µA @ 30V/25°C. | Lacks automotive qualification and high-temp stability; unsuitable for underhood use above 125°C. | Use only in commercial-grade, non-automotive applications with relaxed leakage and reliability needs. |
Compared with SBRT2A30P1-7 and MBR230LSFT1G, SBR2A30P1-7 uniquely combines AEC-Q101 compliance, 75A surge rating, and sub-0.35V VF at 1A-making it the only choice for thermally constrained, high-reliability automotive power rails.

FAQ
What is the maximum allowable PCB pad size for optimal thermal performance?
The recommended pad layout for SBR2A30P1-7 specifies a cathode tab pad of 2.2 mm × 1.4 mm (X1 × Y1) with 1.0 mm gap (G) to adjacent traces. This matches the thermal model used to derive the 5°C/W RθJS value and ensures reliable solder joint integrity during reflow and thermal cycling.
Does SBR2A30P1-7 support lead-free reflow profiles?
Yes-SBR2A30P1-7 is qualified for lead-free reflow with peak temperatures up to 260°C per J-STD-020D. Its matte tin finish and green molding compound meet JEDEC MSL Level 1 requirements, allowing unlimited floor life before assembly without dry-packaging.
How does its reverse avalanche capability compare to standard Schottky diodes?
Unlike standard Schottkys-which fail catastrophically under reverse avalanche-SBR2A30P1-7 is characterized for controlled, non-destructive avalanche operation per AEC-Q101 stress tests. Its patented structure sustains ≥1000 cycles of 30V/1A reverse avalanche without parameter shift.
Can it replace a 3A Schottky in a 2A application?
No-SBR2A30P1-7 is rated for 2.0A average forward current. While its surge rating is high, continuous operation above 2A violates its thermal limits. For 3A applications, consider SBR3A30P1-7 (3A-rated variant in same package) to maintain safety margin and reliability.
