Product details
Overview
SBR1U150SA-13 from Diodes Incorporated is a 1.0A surface-mount Super Barrier Rectifier (SBR®) with 150V peak repetitive reverse voltage, 0.70V max forward voltage at 1.0A/25°C, and 0.1mA max leakage at 150V/25°C, designed for polarity protection and DC-DC converter freewheeling paths in automotive-grade power supplies.
For engineers reviewing the SBR1U150SA-13 datasheet, SBR1U150SA-13 pinout, SBR1U150SA-13 application, or SBR1U150SA-13 equivalent, key selection criteria include ultra-low VF at high temperature, soft switching behavior, +150°C junction rating, and JEDEC-qualified reliability for industrial and automotive environments.
Technical Context
This SBR rectifier uses patented Super Barrier technology to achieve lower forward voltage than standard Schottky diodes while maintaining higher reverse voltage capability and superior thermal stability. Its 9ns reverse recovery time and soft recovery waveform minimize EMI in high-frequency switching converters.
The device operates up to +150°C junction temperature with 3°C/W junction-to-solder thermal resistance, enabling high-power-density designs on FR-4 PCBs using standard SMA footprint. It is qualified per AEC-Q standards and rated for 42A non-repetitive surge current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - blocks DC or AC reverse voltages up to this level without breakdown |
| IO (AV) | 1.0 A - continuous average forward current rating at TA = +25°C with derating above 25°C |
| VF Max | 0.70 V @ 1.0A, 25°C - enables low conduction loss in high-efficiency DC-DC stages |
| IR Max | 0.1 mA @ 150V, 25°C - ensures minimal standby power loss in blocking applications |
| tRR | 9 ns - fast, soft recovery reduces switching noise and voltage overshoot |
| TJ Range | –65°C to +150°C - supports operation in under-hood automotive and industrial ambient conditions |
| RθJS | 3 °C/W - low thermal resistance from die to solder joint improves thermal management |

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT1U150S-13 | Same SBR® technology, identical VRRM/IO/VF, but in SMB package with higher RθJA (100°C/W) | Lower power density due to larger footprint and reduced thermal performance | Select only if SMA footprint unavailable or board space permits larger package |
| SS115H-13-F | Standard Schottky; 15V lower VRRM (135V), 0.82V VF @ 1A, no AEC-Q qualification | Not suitable for 150V bus systems or automotive environments requiring extended lifetime | Acceptable only for cost-sensitive consumer-grade 12V/24V DC-DC where reliability margins are relaxed |
Compared with SBRT1U150S-13 and SS115H-13-F, the SBR1U150SA-13 delivers optimal balance of low VF, high VRRM, soft switching, and automotive qualification in the smallest thermally efficient SMA form factor-making it preferred for space-constrained, high-reliability power conversion.

FAQ
Is SBR1U150SA-13 pin-compatible with standard SMA Schottky diodes?
Yes-SBR1U150SA-13 uses the industry-standard SMA package with anode/cathode terminal configuration matching JEDEC MS-013AC. Its cathode band orientation and mechanical dimensions align precisely with common SMA rectifiers, enabling direct PCB footprint reuse without layout changes.
What is the maximum allowable ambient temperature for continuous 1.0A operation?
Per Figure 5, the device supports 1.0A average forward current up to +70°C ambient temperature on FR-4 PCB with 2oz copper and minimum recommended pad layout. Above +70°C, linear derating applies down to zero current at +150°C ambient.
Does SBR1U150SA-13 require a heatsink for 1.0A operation?
No external heatsink is required. With RθJS = 3°C/W and RθJA = 88°C/W on polyimide PCB (Note 7), the junction temperature remains below +150°C at 1.0A and +70°C ambient. Thermal performance relies on proper copper pour under the cathode tab per Diodes' recommended pad layout.
How does SBR1U150SA-13 differ from the automotive-qualified SBR1U150SAQ?
SBR1U150SAQ is identical in electrical and thermal specifications but undergoes additional AEC-Q101 stress testing and is traceable to automotive-grade wafer lots. The "Q" suffix denotes full automotive qualification; SBR1U150SA-13 is industrial-grade with JEDEC reliability references but not AEC-Q101 certified.
