Product details
Overview
SBR10U45SP5Q-13 from Diodes Incorporated is a 10A, 45V Super Barrier Rectifier (SBR®) diode in PowerDI5 package, featuring ultra-low 0.47V max forward voltage at 10A/25°C, 0.3mA max reverse leakage at 45V/25°C, and AEC-Q101 qualification for automotive polarity protection and recirculation circuits.
For engineers reviewing the SBR10U45SP5Q-13 datasheet, SBR10U45SP5Q-13 pinout, SBR10U45SP5Q-13 application, or SBR10U45SP5Q-13 equivalent, this part delivers rugged avalanche capability (5630W peak), low thermal resistance (31°C/W on polyimide PCB), and high-temperature reliability up to +150°C junction - critical for under-hood power management and DC-DC converter flyback paths.
Technical Context
This SBR device uses patented barrier technology to achieve Schottky-like forward conduction with significantly enhanced avalanche robustness - enabling safe operation during inductive switching transients without external snubbers. Its 34ns reverse recovery time and 800pF junction capacitance support high-frequency rectification in synchronous buck and boost converters.
Designed specifically for automotive-grade reliability, it integrates 100% avalanche testing, halogen/antimony-free "Green" molding compound (UL 94V-0), and matte tin annealed terminals solderable per MIL-STD-202. Thermal performance is validated on both FR-4 (73°C/W) and polyimide (31°C/W) substrates with defined pad layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT10U45SP5-13 | Same die, but non-AEC-Q101 qualified; no PPAP support or IATF 16949 manufacturing traceability. | Limited to industrial/commercial power supplies; not approved for automotive safety-critical functions. | Select only for cost-sensitive non-automotive designs where qualification documentation is unnecessary. |
| SS10H45 | Standard Schottky rectifier; higher VF (0.55V typ), lower avalanche rating (no PARM spec), and no AEC-Q101 certification. | Acceptable for low-temp ambient applications but prone to thermal runaway above 100°C due to higher IR drift. | Use only if board-level thermal management ensures TJ ≤ 100°C and automotive compliance is not required. |
Compared with SBRT10U45SP5-13 and SS10H45, the SBR10U45SP5Q-13 uniquely combines automotive qualification, industry-leading avalanche robustness, and ultra-low VF - making it the sole choice for AEC-compliant high-reliability recirculation and protection in engine bay and EPS systems.

FAQ
What is the maximum junction temperature rating for SBR10U45SP5Q-13?
The SBR10U45SP5Q-13 has a specified operating junction temperature range of –55°C to +150°C. This rating is validated per AEC-Q101 stress tests including temperature cycling and high-temperature reverse bias. Derating curves in the datasheet show usable average forward current drops to ~6.5A at +125°C ambient on FR-4 PCB.
Is SBR10U45SP5Q-13 compatible with lead-free reflow processes?
Yes - the device features matte tin annealed terminals over copper leadframe and is qualified for standard lead-free reflow profiles (J-STD-020, peak 260°C). Its moisture sensitivity level is rated at Level 1, meaning it can be stored indefinitely at ≤30°C/60% RH without baking prior to assembly.
How does the SBR technology differ from conventional Schottky rectifiers?
SBR technology employs a proprietary barrier structure that achieves forward voltage comparable to Schottky diodes (e.g., 0.47V max) while delivering silicon-grade avalanche energy handling (530mJ EAS, 5630W PARM). Unlike Schottky devices, it avoids catastrophic failure under repetitive inductive switching stress - a key differentiator in automotive motor and solenoid drive applications.
Can SBR10U45SP5Q-13 be used in parallel configurations?
Parallel operation is not recommended without individual current-sharing resistors or active balancing, as forward voltage mismatch between units may cause uneven current distribution. The datasheet specifies no guaranteed matching for VF or thermal impedance; for >10A total current, use a single higher-rated device or verify derating with actual board-level thermal measurements.
