Product details
Overview
SBR3M100SB-13 from Diodes Incorporated is a 3.0A surface-mount Super Barrier Rectifier in SMB package, rated for 100V peak repetitive reverse voltage, with max 0.81V forward voltage at 3A/25°C and 1µA reverse leakage at 100V/25°C. It serves as a high-efficiency rectifier in DC-DC converters and polarity protection circuits where low VF and thermal stability are critical.
For engineers reviewing the SBR3M100SB-13 datasheet, SBR3M100SB-13 pinout, SBR3M100SB-13 application, or SBR3M100SB-13 equivalent, key selection criteria include its 65A non-repetitive surge rating, soft fast switching behavior, patented interlocking clip design, and AEC-Q101 readiness for automotive-grade reliability validation.
Technical Context
This Super Barrier Rectifier employs Diodes' proprietary SBR® technology to achieve lower forward voltage than standard Schottky diodes while maintaining superior high-temperature reverse leakage performance-1µA at 25°C and 500µA at 125°C under 100V bias. Its thermal resistance junction-to-lead is 25°C/W, enabling efficient heat transfer in compact layouts.
The device uses a single-anode/cathode configuration with cathode band polarity marking, optimized for unidirectional current flow in half-wave rectification and freewheeling paths. Its SMB package supports automated assembly and meets IPC/JEDEC standards for moisture sensitivity Level 1 and lead-free solderability per MIL-STD-202.

Use Scenario: Reverse-voltage protection on 24V industrial control inputs and USB-C PD ports. IC Role / Device Role / Timing Role: Series-blocking diode preventing damage from miswired power connections. Use Value: 1µA IR at 25°C minimizes quiescent drain in always-on systems; SMB footprint saves board space vs. SMA/SOD-123. | Use Scenario: Freewheeling path for inductive loads such as solenoids, relays, and motor windings. IC Role / Device Role / Timing Role: Clamp-inductive kickback energy during transistor turn-off. Use Value: Soft recovery limits voltage overshoot and EMI; 0.81V VF lowers clamp loss versus standard FR-type diodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBRT3M100SB-13 | Same die, enhanced surge robustness via modified clip geometry; IFSM = 75A | Better suited for high-inrush industrial motor drives and EV charging modules | Select when >65A surge margin is required without changing layout |
| SS310H | Standard Schottky; VF = 0.85V @ 3A but IR = 500µA @ 125°C | Higher leakage may compromise battery backup runtime in low-power IoT nodes | Choose only if cost sensitivity outweighs thermal stability requirements |
Compared with SBRT3M100SB-13, this part trades 10A surge headroom for identical footprint and thermal performance; versus SS310H, it delivers 500× lower IR at 125°C-critical for under-hood automotive modules operating continuously above 100°C.

FAQ
What is the maximum junction temperature and how does it affect derating?
The SBR3M100SB-13 has a rated TJ range of –55°C to +150°C. At 150°C, its VF increases to 0.69V and IR rises to 500µA. Derating is required above 25°C ambient: IO drops linearly to ~1.8A at 100°C ambient on a standard FR-4 board with 0.56" × 0.73" copper pad, per RθJA = 70°C/W.
Is SBR3M100SB-13 qualified to AEC-Q101?
Yes-SBR3M100SB-13 is AEC-Q101 qualified and manufactured in IATF 16949 certified facilities. It undergoes stress testing including HTGB, HTRB, and TCT per AEC-Q101 Rev D. Full PPAP documentation and change control are available upon request for automotive programs.
How does the interlocking clip design improve reliability?
The patented interlocking clip replaces traditional bond wires with a mechanically anchored metal strap between die and lead frame. This eliminates wire-bond fatigue failure modes, enabling 65A IFSM and improved thermal cycling endurance-validated over 1000 cycles from –55°C to +150°C.
Can SBR3M100SB-13 replace standard Schottky diodes like SS310 in existing designs?
Yes-SBR3M100SB-13 is SMB-package compatible with SS310 and offers identical pinout and footprint. However, its lower IR at high temperature (500µA vs. 5000µA for SS310 at 125°C) improves system efficiency and thermal margin in sustained high-temp operation, especially in enclosed enclosures.
