Product details
Overview
SBR8M100P5Q-13D from Diodes Incorporated is an AEC-Q101-qualified Super Barrier Rectifier (SBR) diode in PowerDI5 package, rated for 100 V peak reverse voltage, 8 A average forward current, and 0.88 V max forward voltage at 8 A/25°C. It delivers low leakage (≤100 µA at 100 V/125°C), soft fast switching (16 ns reverse recovery), and robust avalanche energy handling (400 mJ at 5 A/50 mH), designed specifically for automotive polarity protection and DC-DC converter output rectification.
For engineers reviewing the SBR8M100P5Q-13D datasheet, SBR8M100P5Q-13D pinout, SBR8M100P5Q-13D application, or SBR8M100P5Q-13D equivalent, key selection criteria include ISO7637-2 surge compliance (Pulse 1: −600 V, Pulse 2a: +112 V), junction-to-ambient thermal resistance (25 °C/W on 2″ Al board), and AEC-Q101 qualification with PPAP capability for automotive-grade supply chain traceability.
Technical Context
This SBR device employs patented Super Barrier Rectifier technology to achieve lower forward voltage than Schottky diodes while maintaining higher temperature stability and reduced leakage versus conventional PN junctions. Its soft, fast switching behavior minimizes EMI in high-frequency converters, and its 175°C maximum junction temperature supports under-hood operation.
The PowerDI5 package integrates a thermally optimized copper leadframe with exposed heat sink pad, enabling efficient power dissipation. Pin configuration supports PCB-level thermal management via left/right pin connection and bottom-side heatsink mounting-critical for sustained 8 A conduction in space-constrained automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Withstands repetitive reverse voltage up to 100 V without breakdown; meets 24 V system blocking requirements per ISO7637-2 Pulse 2a (+112 V transient). |
| IO | 8 A - Continuous average forward current rating at TA = 25°C on 2″ Al board; derates to ~4.5 A at 100°C ambient. |
| VF (max) | 0.88 V @ 8 A, 25°C - Enables <0.7 W conduction loss at full load, reducing thermal stress in compact DC-DC modules. |
| IR (max) | 100 µA @ 100 V, 125°C - Low leakage preserves efficiency in high-temperature battery management and start-stop systems. |
| tRR | 16 ns - Fast, soft reverse recovery suppresses voltage overshoot and ringing in synchronous rectifier circuits. |
| EAS | 400 mJ @ IAS = 5 A, L = 50 mH - Absorbs inductive energy during load dump or relay coil de-energization without failure. |
| RθJA | 25 °C/W - Thermal resistance on 2″ Al board enables stable operation at 8 A with ≤200°C junction rise above ambient. |
Pinout & Package
Package: PowerDI5 - Surface-mount, thermally enhanced plastic package with exposed copper heat sink pad on bottom side; UL 94V-0 rated molding compound; moisture sensitivity level 1 (J-STD-020); weight ≈ 0.093 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Left Pin | Anode | Primary current entry point; must be electrically connected to right pin on PCB for optimal thermal path and current sharing. |
| Right Pin | Cathode | Current exit terminal; tied to ground or return path; forms low-inductance loop with left pin for fast switching. |
| Bottom Side | Thermal Pad / Heat Sink | Exposed copper area for soldering to large copper pour; provides primary thermal conduction path to PCB. |
Key Features

FAQ
What is the difference between SBR8M100P5Q-13D and standard Schottky diodes?
SBR8M100P5Q-13D uses patented Super Barrier Rectifier technology to achieve Schottky-like forward voltage (0.72–0.88 V) while maintaining significantly lower leakage at high temperature (≤100 µA at 125°C vs. >1 mA for comparable Schottkys) and higher surge robustness (400 mJ EAS). It also features soft recovery (16 ns tRR) to reduce EMI.
Is SBR8M100P5Q-13D qualified for automotive applications?
Yes-SBR8M100P5Q-13D is AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. It meets ISO7637-2 surge immunity requirements (Pulse 1: −600 V, Pulse 2a: +112 V) and operates from −55°C to +175°C junction temperature.
How should the PowerDI5 thermal pad be implemented on the PCB?
The exposed bottom-side copper pad must be soldered to a minimum 100 mm² copper pour with ≥4 thermal vias (0.3 mm diameter, filled or capped) connecting to inner or back-layer ground planes. Left and right pins must be shorted on the PCB to ensure current sharing and optimal thermal conduction through the leadframe.
What packaging options are available for SBR8M100P5Q-13D?
SBR8M100P5Q-13D ships in 5000-unit tape-and-reel format with 12 mm tape width (suffix -13D). The reel complies with EIA-481-D standards and includes moisture barrier bagging per J-STD-020 Level 1. No tray or bulk options are offered for this variant.
