Product details
Overview
SBR1U150SAQ-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 recirculating diode functions in automotive-grade DC-DC converters.
For engineers reviewing the SBR1U150SAQ-13 datasheet, SBR1U150SAQ-13 pinout, SBR1U150SAQ-13 application, or SBR1U150SAQ-13 equivalent, key selection criteria include ultra-low VF at high temperature, soft fast switching behavior, +150°C junction rating, AEC-Q qualified reliability, and SMA package thermal performance under sustained load.
Technical Context
This SBR device uses patented Super Barrier Rectifier technology to achieve lower forward voltage than Schottky diodes while maintaining higher reverse voltage capability and superior high-temperature stability. Its soft recovery characteristic (9ns tRR) minimizes EMI in switching power supplies.
The device is rated for 1.0A average forward current with derating above +25°C ambient, supports 42A non-repetitive surge current, and delivers 6,000W peak avalanche power at 1µs pulse width - enabling robust operation in transient-prone automotive and industrial power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 150 V - blocks up to 150V reverse voltage without breakdown, suitable for 12V/24V automotive systems with load dump margins |
| IO | 1.0 A - continuous rectified output current at +25°C ambient, derated to ~0.6A at +100°C per Fig. 5 |
| VF Max | 0.70 V @ 1.0A/25°C - reduces conduction loss by ~30% vs. standard PN rectifiers, improving efficiency in low-voltage DC-DC stages |
| IR Max | 0.1 mA @ 150V/25°C - ensures minimal standby leakage in blocking applications such as battery isolation |
| tRR | 9 ns - soft, fast reverse recovery limits voltage overshoot and EMI during turn-off in synchronous rectifier circuits |
| TJ Max | +150°C - enables operation in engine bay or under-hood environments without thermal derating penalties |
| CJ | 85 pF @ 4V - low junction capacitance preserves high-frequency switching integrity in buck converter freewheel paths |
Pinout & Package
Package: SMA (Surface-Mount Axial), molded plastic body with UL 94V-0 flammability rating, cathode band marking, and matte tin–plated terminals solderable per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to input/source side in rectification; must handle 42A surge during fault conditions |
| Cathode | Forward current exit / reverse voltage reference | Electrically tied to PCB ground plane or return path; serves as thermal interface (RθJS = 3°C/W) |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low forward voltage | 0.56V @ 1.0A/125°C - maintains efficiency in high-temp environments where conventional Schottkys degrade |
| Soft fast switching | 9ns tRR with low IRR/di/dt - suppresses ringing and reduces snubber component count in flyback and buck topologies |
| AEC-Q qualified reliability | Qualified to JEDEC standards referenced in AEC-Q - validated for automotive use including temperature cycling, HAST, and bond wire pull tests |
| +150°C operating junction | Rated TJ range −65°C to +150°C - eliminates need for oversized heatsinking in space-constrained under-hood modules |
Applications
| Automotive Body Control Module (BCM) | Industrial DC-DC Converter Output Stage |
|---|---|
Use Scenario: Reverse-polarity protection on 12V supply rail feeding microcontroller and CAN transceiver circuitry. IC Role / Device Role / Timing Role: Blocking diode preventing damage during battery jump-start misconnection.

Use Value: 0.56V VF at 125°C ensures minimal voltage drop across diode during hot-charging conditions, preserving system runtime accuracy. |
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 die, identical electrical specs, but non-automotive grade (no AEC-Q qualification) | Not approved for automotive safety-critical modules requiring AEC-Q documentation traceability | Select only for cost-sensitive industrial or consumer designs where automotive qualification is unnecessary |
| SS115H-13-F | Standard Schottky; 15V lower VRRM (135V), 0.85V VF @ 1A/25°C, no soft recovery | Higher conduction loss and EMI risk in high-dV/dt environments; unsuitable for load dump scenarios | Acceptable only in benign ambient environments (<+85°C) with margin on reverse voltage and no EMI constraints |
Compared with SBRT1U150S-13 and SS115H-13-F, SBR1U150SAQ-13 uniquely combines AEC-Q compliance, 150V blocking, ultra-low VF across temperature, and soft recovery - making it the sole choice for automotive-grade recirculation and polarity protection where reliability and efficiency are co-constrained.

FAQ
What is the difference between SBR1U150SAQ-13 and SBR1U150SA-13?
SBR1U150SAQ-13 is the AEC-Q qualified automotive version with full test documentation per JEDEC standards referenced in AEC-Q; SBR1U150SA-13 is the commercial-grade variant lacking automotive qualification records and traceability. Both share identical electrical specs and SMA packaging, but only the "Q" suffix meets automotive PPAP requirements.
Can SBR1U150SAQ-13 be used as a direct replacement for a standard 1N4007 in a 12V AC-DC bridge?
No - SBR1U150SAQ-13 is a single anode-cathode device rated for 1.0A average current and 150V reverse voltage, whereas 1N4007 is a 1A/1000V PN rectifier with different thermal and surge characteristics. It cannot substitute in full-wave bridge configurations without redesigning layout, thermal path, and surge protection.
What is the maximum allowable PCB pad temperature during reflow soldering?
The SMA package supports lead-free reflow per J-STD-020 Level 1 moisture sensitivity. Peak reflow temperature must not exceed 260°C for ≤10 seconds, with ramp rates ≤3°C/s pre-peak. Exceeding these limits risks delamination or internal wire bond failure due to thermal stress on the molded plastic body.
Does SBR1U150SAQ-13 require a heatsink in a 1.0A continuous application at +85°C ambient?
No - with RθJA = 88°C/W on polyimide PCB (Note 7) and 0.56V VF at +125°C junction, power dissipation is ~0.56W, resulting in ~49°C rise above ambient. At +85°C ambient, junction temperature reaches ~134°C - within the +150°C limit, so no external heatsink is required with proper copper pour and via stitching.
