Diodes Incorporated SBR10M100P5Q-13

Overview

SBR10M100P5Q-13 from Diodes Incorporated is a 10A, 100V Super Barrier Rectifier (SBR) diode in PowerDI5 package, featuring ultra-low leakage (≤2 µA @ 100V, +25°C), low forward voltage (0.88 V max @ 10A), 175°C maximum junction temperature, and AEC-Q101 qualification for automotive polarity protection and DC-DC converter recirculation paths.

For engineers reviewing the SBR10M100P5Q-13 datasheet, SBR10M100P5Q-13 pinout, SBR10M100P5Q-13 application, or SBR10M100P5Q-13 equivalent, key selection criteria include avalanche energy rating (400 mJ @ 5A/50mH), thermal resistance (RθJL = 3°C/W), ISO7637-2 surge compliance (Pulse 1: −600V), and soft-switching capability for EMI-sensitive automotive power rails.

Technical Context

This SBR rectifier employs patented Super Barrier Rectifier® technology to achieve simultaneous low VF and ultra-low IR-unattainable with standard Schottky or PN diodes-enabling high-efficiency, high-reliability operation in 24V automotive systems where reverse leakage must remain below 0.1 µA at 125°C.

Its PowerDI5 package integrates a thermally optimized copper leadframe with dual-side heat sinking (cathode-connected tab), delivering RθJL = 3°C/W and supporting 10A continuous current with minimal derating up to +125°C ambient, while maintaining robust avalanche ruggedness (IAS = 20A, EAS = 150 mJ @ 1mH).

FAQ

What is the thermal performance difference between RθJA = 20°C/W and RθJA = 90°C/W listed in the datasheet?

The 20°C/W value applies to a 2-inch² aluminum board (Note 7), representing ideal heatsinking; the 90°C/W value reflects standard FR-4 PCB with 2oz copper (Note 8). Real-world thermal design must use RθJL = 3°C/W to the cathode pad, as this defines the dominant heat path when the bottom tab is soldered to a large copper area-enabling >8W power dissipation before reaching TJ(max).

Does SBR10M100P5Q-13 support bidirectional current flow in automotive CAN or LIN bus protection?

No. This is a unidirectional rectifier diode with anode-cathode polarity; it cannot conduct reverse current. It is not suitable for bidirectional TVS or bus protection. Its role is strictly forward conduction (anode→cathode) for polarity protection, recirculation, or blocking-never signal line clamping or data bus protection.

How does the SBR10M100P5Q-13 compare to standard Schottky diodes in high-temperature automotive applications?

At +125°C, its IR remains ≤0.06 mA (60 µA), whereas typical 100V Schottkys exceed 1 mA-causing unacceptable standby drain. Its VF increases only marginally (0.74 V @ 10A/+125°C vs. 0.59 V @ +25°C), preserving efficiency. Unlike Schottkys, it also withstands repetitive avalanche events without parameter drift, meeting AEC-Q101 requirements.

Is the PowerDI5 package compatible with standard reflow profiles for lead-free assembly?

Yes. The device uses matte tin annealed over copper leadframe and complies with J-STD-020 moisture sensitivity Level 1. It supports standard IPC/JEDEC J-STD-020D reflow profiles, including peak temperatures up to 260°C for ≤30 seconds. The green molding compound is UL 94V-0 rated and halogen/antimony free per Diodes' "Green" definition.
