Product details
Overview
SBR1U30SV-7 from Diodes Incorporated is a 1.0A Super Barrier Rectifier (SBR®) optimized for low-loss DC/DC conversion in space-constrained power supplies, featuring 30V peak reverse voltage, 0.43V typical forward voltage at 1.0A/25°C, and soft fast switching capability. It operates up to +150°C junction temperature and is packaged in SOT563 for high-density PCB layouts in portable and industrial power modules.
For engineers reviewing the SBR1U30SV-7 datasheet, SBR1U30SV-7 pinout, SBR1U30SV-7 application, or SBR1U30SV-7 equivalent, key selection criteria include forward voltage drop at 1.0A, leakage current at 30V/125°C (4mA), thermal resistance (130°C/W), and SOT563 footprint compatibility with automated assembly.
Technical Context
This SBR rectifier replaces conventional Schottky diodes in low-voltage, high-efficiency buck converters and OR-ing circuits where low VF and minimal reverse recovery loss are critical. Its patented super barrier structure delivers lower leakage than standard Schottkys while maintaining soft switching behavior and stable performance across –65°C to +150°C.
The device uses a copper leadframe with matte tin terminals, achieves 7–150µA leakage at VR = 5–30V/25°C, and exhibits 1000pF total capacitance at 0V reverse bias (f = 1MHz), supporting high-frequency switching up to several hundred kHz without excessive ringing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage | 30 V - supports 24V rail input stages with 20% derating margin |
| Avg. Forward Current | 1.0 A - rated for continuous conduction mode operation in compact 1W–2W DC/DC converters |
| Forward Voltage @1A/25°C | 0.43 V - reduces conduction loss by ~30% vs. comparable 30V Schottky diodes |
| Leakage @30V/125°C | 4 mA - enables stable operation in thermally stressed environments without thermal runaway |
| Junction Temp Range | –65°C to +150°C - qualified for under-hood automotive and industrial control applications |
| Thermal Resistance θJA | 130 °C/W - requires minimum pad layout per AP02001 for reliable 1A operation on FR-4 |
| Total Capacitance @0V | 1000 pF - limits high-frequency EMI generation in synchronous rectifier topologies |

Use Value: 2.5A non-repetitive surge rating and 150°C TJ capability allow direct placement on PCB without heatsink, reducing BOM count. |
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-1EWH03-M3 | Same 30V VRRM, but 0.49V VF @1A/25°C; higher 10mA IR @30V/125°C | Larger SOD-123FL package (3.7mm × 1.7mm); less suitable for ultra-dense layouts | Prefer when legacy footprint compatibility outweighs VF/leakage optimization |
| ON Semiconductor SBRA130 | 30V VRRM, 0.45V VF @1A/25°C; 120µA IR @30V/25°C; no 125°C leakage spec published | SOD-523 package (1.3mm × 0.85mm); lower thermal mass, higher θJA (~220°C/W) | Prefer for smallest possible footprint where ambient temperature stays ≤85°C |
Compared with VS-1EWH03-M3 and SBRA130, the SBR1U30SV-7 delivers the lowest combined VF/IR trade-off in SOT563, making it optimal for thermally constrained, high-efficiency 1A rectification where board area and thermal management are co-optimized.

FAQ
What is the maximum allowable soldering temperature profile for SBR1U30SV-7?
The SBR1U30SV-7 is qualified to JEDEC J-STD-020 Level 1 moisture sensitivity and supports standard lead-free reflow profiles with peak temperature up to 260°C for ≤10 seconds. Preheat ramp rate must not exceed 3°C/s, and time above 217°C shall be 60–150 seconds. No special pre-baking is required due to its Level 1 classification.
Can SBR1U30SV-7 be used in place of a standard Schottky diode in an existing design?
Yes-SBR1U30SV-7 is a direct functional replacement for 30V/1A Schottky diodes in most applications. Its dual-anode/dual-cathode SOT563 pinout matches common layout practices, and its lower VF (0.43V vs. typical 0.55V) improves efficiency. However, verify thermal performance: its 130°C/W θJA requires adherence to Diodes' AP02001 pad layout for full 1A rating.
Does SBR1U30SV-7 meet automotive AEC-Q101 requirements?
No-SBR1U30SV-7 is not AEC-Q101 qualified. While it operates from –65°C to +150°C and meets RoHS/Green standards, Diodes Incorporated does not list this specific part number in its AEC-Q101-certified portfolio. For automotive body electronics, consider the AEC-Q101-qualified SBR1A30SP5-13 (same specs, SOD-123FL package) instead.
How does the dual-anode/dual-cathode configuration affect PCB layout?
The SOT563 package integrates two anodes (pins 1 & 3) and two cathodes (pins 2 & 4) to reduce parasitic inductance and distribute current. Layout must connect both anodes to the same net (e.g., switch node) and both cathodes to the same net (e.g., output rail). Avoid splitting traces-this configuration is designed for symmetric, low-inductance routing in high-frequency converters.
