Product details
Overview
SBR2M100SB-13 from Diodes Incorporated is a 2.0A surface-mount Super Barrier Rectifier in SMB package, featuring 100V peak repetitive reverse voltage, max 0.78V forward voltage at 2A/25°C, <1µA reverse leakage at 100V/25°C, and 65A non-repetitive surge current - deployed as polarity protection and recirculating diodes in DC-DC converters.
For engineers reviewing the SBR2M100SB-13 datasheet, SBR2M100SB-13 pinout, SBR2M100SB-13 application, or SBR2M100SB-13 equivalent, key selection criteria include low VF stability at +125°C, thermal resistance (RθJL = 25°C/W), RoHS-compliant matte tin terminals, and AEC-Q101 readiness for automotive-grade power management designs.
Technical Context
This Super Barrier Rectifier uses patented SBR® technology to achieve lower forward voltage than Schottky diodes while maintaining superior high-temperature reverse leakage performance. Its interlocking clip design enables 65A IFSM capability without bond wire limitations.
Rated for continuous 2.0A average output current with derating for capacitive loads, it operates across –55°C to +150°C junction temperature range and exhibits soft, fast switching behavior critical for reducing EMI in high-frequency switching topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - blocks up to 100V reverse bias without breakdown in rectification paths |
| IO (AVG) | 2.0 A - supports continuous DC output current in compact SMB footprint |
| VF (MAX) | 0.78 V @ 2A, 25°C - reduces conduction loss vs. standard PN diodes; 0.65V @ 125°C confirms thermal stability |
| IR (MAX) | 1 µA @ 100V, 25°C - ensures minimal standby power loss; 500 µA @ 125°C maintains blocking integrity at elevated temp |
| IFSM | 65 A - withstands transient inrush during startup or fault recovery in SMPS |
| RθJL | 25 °C/W - enables efficient heat transfer from junction to PCB pad via lead frame |
| Polarity | Cathode band marked - unambiguous orientation for automated placement and visual inspection |
Pinout & Package
Package: SMB (Surface Mount Body), molded plastic case with UL 94V-0 rating, 0.093g weight, matte tin–annealed copper lead-frame, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to input/source side of rectifier path; requires adequate copper pour for thermal dissipation |
| Cathode | Current exit point during forward conduction; marked with band | Connected to output/load side; cathode band enables rapid orientation verification on PCB and AOI systems |
Key Features
| Feature | Design Value |
|---|---|
| Patented SBR® technology | Combines low VF of Schottky with low IR of PN diodes - eliminates trade-off between efficiency and leakage in 100V-class rectifiers |
| Interlocking clip construction | Enables 65A surge rating without wire bonds - improves reliability under repeated thermal cycling and load transients |
| Soft, fast switching | Minimizes reverse recovery ringing and EMI generation in >100kHz DC-DC converters |
| Halogen & antimony free ("Green") | Meets IEC 61249-2-21: <900ppm Br, <900ppm Cl, <1000ppm Sb - compliant with automotive and industrial environmental mandates |
Applications
| DC-DC Converter | AC-DC Rectifier |
|---|---|
Use Scenario: Secondary-side synchronous rectification in isolated flyback or forward converters. IC Role / Device Role / Timing Role: Unidirectional current steering diode replacing MOSFETs where gate drive complexity is undesirable. Use Value: 0.78V VF at 2A lowers conduction loss by ~30% vs. standard PN diodes, improving light-load efficiency without control-loop redesign. | Use Scenario: Input bridge or output rectification in offline AC-DC adapters and power supplies. IC Role / Device Role / Timing Role: High-reliability blocking element handling 50/60Hz line frequency and harmonics. Use Value: Stable 1µA IR at 25°C and 500µA at 125°C prevents thermal runaway in sealed enclosures with limited airflow. |
| Polarity Protection | Re-Circulating Diode |
Use Scenario: Reverse-voltage safeguard on 12V/24V automotive ECUs and industrial controllers. IC Role / Device Role / Timing Role: Series-connected anode-in configuration blocking reverse battery connection. Use Value: 100V VRRM exceeds automotive load-dump transients (ISO 7637-2 Pulse 5a); SMB footprint fits tight board space constraints. | Use Scenario: Inductive energy clamping across solenoids, relays, and motor windings in power stages. IC Role / Device Role / Timing Role: Freewheeling path for stored magnetic energy during switch-off transitions. Use Value: Soft switching behavior suppresses voltage spikes >40V, eliminating need for snubbers in 24V/2A actuator drivers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar super barrier rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| VB20100C-G | Same 100V/2A rating; VF = 0.75V @ 2A but higher IR = 5µA @ 25°C; TO-220AC package | Requires heatsink mounting; unsuitable for space-constrained SMT layouts | Select when higher surge margin (100A IFSM) and through-hole assembly are acceptable |
| SS210H | 100V/2A Schottky; VF = 0.85V @ 2A; IR = 500µA @ 25°C; SMB package | Larger leakage at room temp limits use in low-power standby circuits | Select only if cost priority outweighs leakage-sensitive operation above 85°C |
Compared with VB20100C-G and SS210H, SBR2M100SB-13 uniquely balances ultra-low VF, sub-1µA IR at 25°C, SMB mountability, and 65A surge tolerance - making it optimal for thermally constrained, high-efficiency automotive and industrial DC-DC modules.

FAQ
What is the maximum junction temperature for continuous operation?
The SBR2M100SB-13 has a rated operating junction temperature range of –55°C to +150°C. Continuous operation at +150°C is permitted provided thermal design ensures actual TJ does not exceed this limit - verified via RθJL = 25°C/W and measured case temperature under full 2A load.
Is SBR2M100SB-13 qualified to AEC-Q101?
Yes - Diodes Incorporated qualifies the SBR2M100SB-13 to AEC-Q101 Rev D for stress testing including HTGB, HTRB, TST, and mechanical shock. Full PPAP documentation and IATF 16949-certified manufacturing are available upon request for automotive programs.
How does its soft switching behavior reduce EMI?
Unlike abrupt-recovery PN diodes, the SBR2M100SB-13 exhibits controlled minority-carrier recombination and low reverse recovery charge (Qrr < 20nC). This minimizes high-frequency ringing during turn-off, directly lowering conducted and radiated emissions in 300–500kHz switching converters.
Can it replace standard Schottky diodes in existing designs?
Yes - with identical SMB footprint and cathode-band polarity, SBR2M100SB-13 is a drop-in replacement for Schottkys like SS210H. It delivers lower VF and significantly better high-temp IR, but requires validation of layout thermal relief since its RθJA (70°C/W) assumes specific 0.56"×0.73" copper pad per datasheet Figure 1.
