Product details
Overview
SBR2U30SA-13 from Diodes Incorporated is a 2.0A surface-mount Super Barrier Rectifier in SMA package, featuring ultra-low forward voltage (0.26 V typ. @ 0.1A, 25°C), 30 V peak repetitive reverse voltage, and 150°C maximum junction temperature. It delivers soft fast switching and low leakage (500 µA max @ 30V, 25°C) for DC-DC converter output rectification in compact power supplies.
For engineers reviewing the SBR2U30SA-13 datasheet, SBR2U30SA-13 pinout, SBR2U30SA-13 application, or SBR2U30SA-13 equivalent, key selection criteria include forward voltage drop at high temperature, surge current rating (30 A IFSM), thermal resistance (5 °C/W junction-to-solder), RoHS-compliant lead-free plating, and green halogen-free molding compound.
Technical Context
This Super Barrier Rectifier uses patented diode technology to achieve lower VF than Schottky devices while maintaining higher reverse breakdown stability and reduced temperature coefficient. Its soft recovery minimizes EMI in high-frequency switching converters.
The device operates across -65°C to +150°C with RθJS = 5 °C/W into cathode tab, enabling high-current density layouts on FR-4 PCBs using minimum recommended pad dimensions (E = 4.8–5.59 mm, B = 4.0–4.60 mm). Reverse leakage remains under 100 mA at 125°C and 30 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage | 30 V - defines maximum DC blocking capability without breakdown in power supply output stage |
| Forward Current (Avg) | 2.0 A - continuous conduction limit for sustained load delivery in 5–12 V DC-DC outputs |
| Forward Voltage (Typ) | 0.26 V @ 0.1A, 25°C - enables >95% efficiency in low-voltage, high-current rectification |
| Surge Current (IFSM) | 30 A - withstands inrush and transient overloads during startup or fault conditions |
| Junction Temp Range | -65°C to +150°C - supports operation in automotive under-hood and industrial ambient environments |
| Thermal Resistance | 5 °C/W (Junction-to-Solder) - allows direct thermal path to PCB copper for passive cooling |
| Leakage Current | 500 µA max @ 30V, 25°C - ensures minimal standby power loss in always-on systems |

Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT2U30S-13 | Same die, enhanced thermal pad design; RθJS = 4.2 °C/W (vs. 5.0) | Better suited for high-power-density designs requiring sub-10°C ΔT at 2 A | Select when board space is constrained and thermal performance is prioritized over cost |
| MBR230LSFT1G | Schottky diode, VF = 0.45 V min @ 2 A, 25°C; lower IR but higher VF drift with temperature | Higher conduction loss above 85°C; requires larger heatsinking in hot environments | Choose only if legacy Schottky footprint compatibility is mandatory and ambient stays below 70°C |
Compared with SBRT2U30S-13, SBR2U30SA-13 trades 0.8 °C/W higher thermal resistance for lower cost and standard SMA footprint; versus MBR230LSFT1G, it delivers 40% lower conduction loss at 125°C but requires verification of reverse voltage margin in high-noise systems.

FAQ
What is the maximum allowable soldering temperature profile for SBR2U30SA-13?
The device is qualified for lead-free reflow per J-STD-020, with peak temperature up to 260°C for ≤30 seconds. Preheat ramp rate must not exceed 3°C/s, and time above 217°C shall be 60–150 seconds. Matte tin plating ensures reliable wetting without voiding on OSP or ENIG finishes.
Can SBR2U30SA-13 be used in place of a standard Schottky diode in an existing design?
Yes, provided the circuit's reverse voltage stress remains ≤30 V and layout accommodates the SMA package's 4.8–5.59 mm E dimension. Forward voltage reduction improves efficiency, but verify that reduced reverse recovery does not interact with existing snubber networks or cause unintended gate drive coupling.
Does SBR2U30SA-13 require a heatsink in 2.0 A continuous operation?
No external heatsink is required when mounted on a 2 oz. copper FR-4 PCB with the manufacturer-recommended pad layout (minimum 5.59 mm × 4.00 mm cathode pad). At 25°C ambient, junction temperature rises ~10°C; at 70°C ambient, it reaches ~115°C - well within the 150°C limit.
How does the green molding compound affect long-term reliability?
The halogen- and antimony-free compound meets IPC-1752A requirements and shows no degradation in thermal cycling (−65°C to +150°C, 1000 cycles) or high-temperature storage (150°C, 1000 hrs). It eliminates corrosive halogen gas evolution during reflow or field failure, improving system-level corrosion resistance.
