Product details
Overview
SBR2U30P1-7 from Diodes Incorporated is a 2.0A, 30V Super Barrier Rectifier (SBR®) in POWERDI®123 package, featuring ultra-low forward voltage (0.22V typ. @ 0.1A, 25°C), ±16kV HBM ESD rating, and AEC-Q101 qualification for automotive power conversion. It delivers soft fast switching, high surge capability (75A IFSM), and operates up to +150°C junction temperature.
For engineers reviewing the SBR2U30P1-7 datasheet, SBR2U30P1-7 pinout, SBR2U30P1-7 application, or SBR2U30P1-7 equivalent, key selection criteria include forward voltage at high temperature, avalanche energy rating (105 mJ), reverse leakage at 30V/125°C (≤20 mA), and thermal resistance (5°C/W junction-to-solder point).
Technical Context
This SBR rectifier uses patented Super Barrier technology to achieve Schottky-like low VF while maintaining higher reverse blocking integrity and superior avalanche ruggedness versus standard Schottky diodes. Its interlocking clip design enables robust 75A non-repetitive surge current handling without bond-wire limitations.
The device is optimized for DC-DC secondary-side rectification in space-constrained, thermally demanding environments-especially automotive infotainment power supplies and industrial 12V/24V auxiliary rails-where low conduction loss, high reliability, and ESD-hardened operation are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in 12V/24V automotive systems with load dump transients. |
| IF(AV) | 2.0 A - Average forward current rating; supports continuous output of compact 5–10W DC-DC converters. |
| VF | 0.22 V (typ.) @ 0.1A, 25°C - Ultra-low conduction loss reduces heat generation and improves efficiency in low-voltage, high-current paths. |
| IFSM | 75 A - Non-repetitive surge current capacity; withstands inrush and fault currents in automotive power modules. |
| EAS | 105 mJ - Avalanche energy rating; ensures robustness against inductive switching transients without clamping circuitry. |
| RθJS | 5 °C/W - Junction-to-solder thermal resistance; enables direct thermal coupling to PCB copper, critical for thermal management in sealed enclosures. |
Pinout & Package
Package: POWERDI®123 - surface-mount, single-ended, 3-pin plastic package with exposed cathode tab for enhanced thermal dissipation and mechanical stability. Dimensions: 1.78 × 3.70 × 0.98 mm (L × W × H); weight ≈ 0.018 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input terminal for forward conduction | Connected to transformer secondary or switch node; requires low-inductance layout to minimize switching noise. |
| Cathode | Output terminal / common return path | Exposed metal tab - must be soldered to ≥25 mm² copper pour for thermal and electrical performance. |
| Cathode Band | Polarity indicator | Visible marking on top surface; confirms cathode orientation during automated placement and visual inspection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT2U30P1-7 | Same die, enhanced thermal pad design; RθJS = 4.5°C/W (vs. 5°C/W); slightly lower VF at 2A/125°C (0.32V vs. 0.33V). | Preferred for ultra-high-density layouts where <0.5°C/W thermal margin is required. | Select when thermal budget is constrained below 10°C rise at 2A ambient. |
| PS1040L-13 | 40V VRRM, 1.0A IF(AV), VF = 0.38V @ 1A/25°C; no AEC-Q101 qualification; higher leakage at 125°C. | Suitable for non-automotive 24V industrial supplies where higher voltage margin is needed but temperature stress is lower. | Choose only if 40V blocking is mandatory and AEC-Q101 compliance is not required. |
Compared with SBRT2U30P1-7, SBR2U30P1-7 offers identical electrical performance with marginally higher thermal resistance-acceptable in most automotive modules-but lacks the latest thermal enhancement. Versus PS1040L-13, it trades off voltage headroom for significantly lower VF, tighter leakage, and full automotive qualification.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The SBR2U30P1-7 is rated for continuous operation up to +150°C junction temperature. Derating begins above +125°C ambient per Figure 5; at 2.0A average current, maximum ambient temperature is ~80°C on a standard FR-4 PCB with 2 oz. copper and recommended pad layout.
Does this part require a heatsink for 2.0A operation?
No external heatsink is required. With RθJS = 5°C/W and typical PCB copper thermal mass, the device achieves ≤10°C junction-to-solder rise at 2.0A/25°C ambient. Full thermal performance depends on cathode tab solder coverage-minimum 25 mm² of 2 oz. copper is recommended per AP02001.
How does the SBR2U30P1-7 compare to standard Schottky diodes in avalanche performance?
Unlike standard Schottky diodes-which fail catastrophically under avalanche conditions-the SBR2U30P1-7 is characterized for 105 mJ non-repetitive avalanche energy (EAS) and 1.1 kW repetitive peak avalanche power (PARM). This enables reliable operation in inductive switching circuits without external TVS clamping.
Is the POWERDI®123 package compatible with standard SMT reflow profiles?
Yes. The POWERDI®123 package is qualified for lead-free reflow per J-STD-020, with peak temperatures up to 260°C. Its matte tin finish over copper leadframe ensures excellent solderability, and moisture sensitivity level is rated at Level 1-no baking required prior to assembly.
