Product details
Overview
SBR2U150SA-13 from Diodes Incorporated is a 2.0A surface-mount Super Barrier Rectifier (SBR®) with 150V peak repetitive reverse voltage, ultra-low forward voltage drop (0.65V at 2.0A/125°C), and +175°C maximum junction temperature-designed for high-efficiency DC/DC conversion in automotive power supplies and industrial SMPS.
For engineers reviewing the SBR2U150SA-13 datasheet, SBR2U150SA-13 pinout, SBR2U150SA-13 application, or SBR2U150SA-13 equivalent, key selection criteria include soft-switching behavior, thermal resistance (RθJA = 88°C/W on polyimide PCB), leakage current (10mA at 150V/125°C), and AEC-Q101 qualification readiness for automotive-grade reliability.
Technical Context
This SBR rectifier employs patented Super Barrier technology to achieve lower VF than Schottky diodes while maintaining higher reverse voltage capability and superior high-temperature stability. Its soft, fast switching minimizes EMI in high-frequency converters.
The device operates up to +175°C junction temperature and exhibits low dv/dt rating (10,000 V/µs), enabling robust performance in noisy automotive environments. It uses an SMA package with cathode band polarity marking and matte tin lead-free plating compliant with RoHS 3 and halogen-free "Green" standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - Maximum reverse blocking voltage without breakdown; enables use in 12V/24V automotive systems with transient suppression headroom. |
| IF(AV) | 2.0 A - Continuous average forward current rating at TA = 25°C; derates to ~1.3A at +100°C ambient per Fig. 5. |
| VF | 0.65 V @ 2.0A, 125°C - Low conduction loss improves efficiency in high-temp power stages; 0.8V @ 25°C confirms soft turn-on. |
| IFSM | 42 A - Non-repetitive surge current handling for load dump or cold-crank transients in automotive applications. |
| RθJA | 88 °C/W - Thermal resistance on 2oz polyimide PCB; supports compact layout with minimal heatsinking in space-constrained modules. |
| IR | 10 mA @ 150V, 125°C - Controlled leakage ensures stable bias in high-temp standby circuits without excessive quiescent loss. |
| TJ Range | –65°C to +175°C - Full automotive-grade operating range; validated for under-hood and engine-control module deployment. |
Pinout & Package
Package: SMA (Surface-Mount Axial), molded plastic UL 94V-0 housing, cathode band polarity indicator, 0.064g mass. Terminal connections use matte tin (lead-free) plating, solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current terminal | Connected to input rail (e.g., battery or converter secondary); accepts 2.0A continuous forward current. |
| Cathode | Output current terminal | Connected to output node (e.g., bulk capacitor or regulator input); marked by visible band; serves as thermal path to PCB pad. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF at high temperature | 0.65V @ 2.0A/125°C - reduces conduction loss by >30% vs. standard Schottky diodes at elevated ambient. |
| Soft, fast switching | No reverse recovery tail current - suppresses EMI and eliminates snubber requirements in 300–500kHz SMPS designs. |
| +175°C operating junction | Rated for continuous operation up to 175°C - supports placement near hot components (e.g., MOSFETs, inductors) without derating. |
| AEC-Q101 ready | Manufactured in IATF 16949 certified facilities; PPAP-capable - meets baseline automotive change control and traceability requirements. |
| Halogen & antimony free | <900ppm Br, <900ppm Cl, <1000ppm Sb - satisfies EU ELV and OEM green material mandates for vehicle electronics. |
Applications
| Automotive DC/DC Converters | Industrial SMPS Outputs |
|---|---|
Use Scenario: Secondary-side rectification in 12V-to-5V/3.3V buck-derived converters for ADAS ECUs and infotainment modules. IC Role / Device Role / Timing Role: Output rectifier replacing Schottky diodes to reduce conduction loss and improve thermal margin. Use Value: Enables 2.0A output at +125°C ambient without forced air cooling due to 0.65V VF and 88°C/W RθJA. | Use Scenario: Output stage in 48V-to-12V telecom and factory automation PSUs operating continuously at 60°C ambient. IC Role / Device Role / Timing Role: High-reliability freewheeling diode in synchronous rectifier-assisted topologies. Use Value: Soft switching eliminates voltage spikes across primary-side MOSFETs, reducing gate drive stress and EMI filter size. |
| LED Driver Power Supplies | Server PSU Hold-Up Circuits |
Use Scenario: Input rectification in constant-current LED drivers for exterior lighting with wide ambient range (–40°C to +105°C). IC Role / Device Role / Timing Role: AC-input bridge leg or DC-input OR-ing diode in dual-rail configurations. Use Value: Low IR (75µA @ 25°C) prevents false triggering of overvoltage protection during cold start. | Use Scenario: Bulk capacitor charging path in redundant 12V server PSUs requiring hold-up time extension during AC dropout. IC Role / Device Role / Timing Role: Reverse-blocking diode isolating backup supply rails during normal operation. Use Value: 42A IFSM withstands inrush surges from large electrolytic banks without degradation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT2U150S-13 | Same die, but in SMB package (larger footprint, RθJA = 70°C/W); 2.0A rating at 25°C only. | Better thermal performance on FR-4, but incompatible with SMA-reflow profiles and board space. | Select when board layout allows SMB and higher ambient derating is acceptable. |
| SS215H-13-F | Standard Schottky; VF = 0.85V @ 2A/25°C, TJ max = +150°C, no soft switching. | Higher conduction loss and reverse recovery noise limit use in high-frequency, low-noise designs. | Select only for cost-sensitive non-automotive applications where 150°C max junction suffices. |
Compared with SBRT2U150S-13 and SS215H-13-F, the SBR2U150SA-13 uniquely delivers 175°C operation, soft switching, and SMA compatibility-making it optimal for space-constrained, thermally aggressive automotive and industrial power stages where reliability and EMI control are critical.

FAQ
Is SBR2U150SA-13 qualified to AEC-Q101?
No, SBR2U150SA-13 is not formally AEC-Q101 qualified, but Diodes states it is manufactured in IATF 16949-certified facilities and PPAP-capable. Customers requiring full AEC-Q101 certification should contact Diodes directly for qualified alternatives such as the SBR2U150S-13Q, which carries the Q suffix and full test report documentation.
What is the recommended PCB pad layout for SMA package thermal performance?
The recommended pad layout uses a 4.00 mm × 1.50 mm cathode pad (G dimension) with 2.50 mm × 6.50 mm copper extension (X1) and 1.70 mm width (Y), per Diodes' outline DWG# SMA-1. This layout achieves RθJA = 88°C/W on polyimide PCBs and must use 2 oz copper to meet thermal specs.
How does SBR2U150SA-13 compare to standard Schottky diodes in reverse leakage at high temperature?
At 150V and +125°C, SBR2U150SA-13 specifies 10 mA IR-higher than typical Schottky diodes-but this is intentional: its super barrier structure trades slightly higher leakage for vastly improved high-temperature stability and absence of thermal runaway, unlike conventional Schottkys that exhibit exponential IR growth above 100°C.
Can SBR2U150SA-13 be used in place of a 1N5822 in an existing design?
Yes, as a direct SMA-footprint replacement, but with key differences: SBR2U150SA-13 offers lower VF (0.65V vs. ~0.9V), higher TJ (175°C vs. 125°C), and soft switching-reducing EMI and improving efficiency. However, its 10 mA IR at 125°C exceeds 1N5822's ~1 mA, so verify downstream bias circuit tolerance before substitution.
