Product details
Overview
SBR2U100LP from Diodes Incorporated is a 1.5A Super Barrier Rectifier (SBR®) diode optimized for automotive polarity protection and recirculation circuits, featuring 100V peak reverse voltage, ≤0.85V forward voltage at 1.5A/25°C, ≤50µA leakage at 100V/25°C, and AEC-Q101 qualification for under-hood applications.
For engineers reviewing the SBR2U100LP datasheet, SBR2U100LP pinout, SBR2U100LP application, or SBR2U100LP equivalent, key selection criteria include its 175°C junction temperature rating, soft fast switching behavior, low thermal resistance (100°C/W), and DFN1411-3 package compatibility with high-density automotive PCB layouts.
Technical Context
This SBR device employs patented super barrier technology to achieve lower forward voltage than standard Schottky diodes while maintaining superior high-temperature leakage performance. Its structure enables stable operation up to TJ = +175°C with VF drift <15% from 25°C to 125°C and IR increase limited to 60µA at 125°C under full 100V bias.
The X1-DFN1411-3 package integrates a copper leadframe with matte tin annealed terminals, supporting reflow soldering per MIL-STD-202 and achieving 100°C/W junction-to-ambient thermal resistance on a 1-inch² 2-oz copper pad. It operates in DC forward mode with VR ≤ 80% VRRM across –55°C to +150°C ambient range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT1A100P5-7 | 1.0A IO, same 100V VRRM, VF = 0.75V @ 1A, smaller DFN1006-3 package | Limited to lower-current auxiliary rails; not rated for 1.5A continuous automotive loads | Select when space-constrained and peak current ≤1.0A; verify thermal margin with RθJA = 130°C/W |
| PS1040L-13 | 1.0A IO, 40V VRRM, VF = 0.45V @ 1A, TO-277 package | Lower voltage rating restricts use to 12V-only systems; larger footprint and higher RθJA = 150°C/W | Choose only for non-AEC-Q101 12V consumer applications where ultra-low VF outweighs automotive qualification needs |
Compared with SBRT1A100P5-7 and PS1040L-13, SBR2U100LP uniquely delivers 1.5A current capacity with AEC-Q101 compliance and 100V blocking in a thermally efficient DFN1411-3 package-making it the sole fit for high-reliability 24V commercial vehicle power management.

FAQ
What is the maximum allowable ambient temperature for continuous 1.5A operation?
At 1.5A DC, the SBR2U100LP must be operated below +85°C ambient temperature to maintain junction temperature ≤+175°C, based on its 100°C/W RθJA and 0.85V VF. Derating curves in Figure 4 confirm 1.5A is sustainable up to +85°C on a 1-in² 2-oz copper pad; above this, current must be reduced linearly to 1.0A at +125°C ambient.
Is the exposed thermal pad electrically isolated or connected internally?
The exposed pad is electrically connected to the cathode terminal (Pin 2) and must be soldered to a PCB ground plane or cathode net. It is not isolated-it serves as both thermal conduction path and cathode extension, improving power dissipation and mechanical stability in high-vibration automotive environments.
Does SBR2U100LP require a minimum solder mask opening around the pad?
Yes-the recommended pad layout specifies a 1.2mm × 0.9mm solder mask opening centered on the 1.4mm × 1.1mm body, with 0.15mm solder mask dams between terminals. This ensures reliable solder wetting of the exposed pad while preventing bridging to adjacent pins during reflow.
How does SBR2U100LP's soft recovery compare to standard Schottky diodes in EMI-sensitive ADAS systems?
SBR2U100LP exhibits soft reverse recovery with <10ns reverse recovery time and minimal current tail, reducing high-frequency ringing by >20dB compared to standard Schottky diodes in 12V solenoid drive circuits. This directly lowers conducted EMI in camera and radar modules, easing CISPR 25 Class 5 compliance without added filtering.
