Product details
Overview
SBR1045SP5Q-13D from Diodes Incorporated is a 10A, 45V Super Barrier Rectifier (SBR®) in PowerDI5 package, designed for high-efficiency freewheeling and bypass applications in solar panels and DC-DC converters. It delivers 0.55V max forward voltage at 10A/25°C, 0.45mA max reverse leakage at 45V/150°C, and is AEC-Q101 qualified for automotive use with 200°C max junction temperature rating.
For engineers reviewing the SBR1045SP5Q-13D datasheet, SBR1045SP5Q-13D pinout, SBR1045SP5Q-13D application, or SBR1045SP5Q-13D equivalent, key selection criteria include its low VF stability across temperature, 180A non-repetitive surge capability, thermal resistance of 3°C/W (junction-to-lead), and PowerDI5 footprint compatibility with high-power PCB layouts requiring minimal thermal pad area.
Technical Context
This SBR rectifier employs patented Super Barrier technology to achieve Schottky-like forward conduction with significantly improved reverse leakage and temperature stability versus conventional Schottky diodes. Its architecture enables operation up to +200°C junction temperature under DC forward mode, supported by RθJL = 3°C/W and RθJC = 6°C/W thermal performance on FR-4 PCBs.
The device features 23ns typical reverse recovery time (tRR) at IF = 0.5A/IR = 1.0A, 500pF typical junction capacitance at 4V, and avalanche-rated peak pulse power of 10,000W (1µs). It is rated for 45V repetitive reverse voltage and supports 10A average rectified output current with 20% derating for capacitive loads.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT1045SP5-13D | Same die, identical electrical specs, but not AEC-Q101 qualified; no PPAP support | Restricted to commercial/industrial use; unsuitable for automotive OEM programs | Select when AEC-Q101 compliance is not required and cost optimization is prioritized |
| MBR1045CT | Standard dual Schottky in TO-220AC; VF = 0.75V @ 10A; IR = 10mA @ 125°C; no 200°C rating | Larger footprint, higher conduction loss, limited to ≤150°C operation | Choose only if legacy TO-220 layout exists and thermal margin exceeds 30°C |
Compared with SBRT1045SP5-13D, the SBR1045SP5Q-13D adds automotive qualification and change control rigor; versus MBR1045CT, it delivers 26% lower VF, 95% lower IR at 150°C, and 33% smaller footprint - making it optimal for space-constrained, high-temperature, and safety-critical designs.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The SBR1045SP5Q-13D is rated for continuous DC forward operation up to +200°C junction temperature for durations up to 2 hours, as specified in Note 8 of the datasheet. For indefinite operation, the recommended maximum junction temperature is +150°C under VR ≤ 80% VRRM, per the Absolute Maximum Ratings table.
Is the PowerDI5 package lead-free and RoHS compliant?
Yes - the SBR1045SP5Q-13D uses matte tin annealed over copper leadframe, is fully RoHS 3 compliant (2015/863/EU), and meets Diodes Incorporated's "Green" definition: <900ppm bromine, <900ppm chlorine, and <1000ppm antimony, verified per internal material testing protocols.
How does the thermal performance differ between FR-4 and polyimide PCBs?
On FR-4 with 2oz copper and minimum recommended pad layout, RθJA = 102°C/W; on polyimide PCBs with same copper weight, RθJA improves to 60°C/W due to superior thermal conductivity. Both values assume proper soldering of the exposed heatsink slug to the PCB thermal pad.
Can this diode be used as a direct replacement for standard Schottky rectifiers in existing designs?
Yes - the SBR1045SP5Q-13D shares identical PowerDI5 footprint and pinout with industry-standard 10A Schottky rectifiers, but offers lower VF and dramatically improved high-temperature leakage. Layout changes are unnecessary, though thermal validation at +125°C+ ambient is recommended due to its extended TJ capability.
