Product details
Overview
B2100-13 from Diodes Incorporated is a 2.0A, 100V Schottky barrier rectifier in SMB package, featuring 0.79V forward voltage at 2.0A/25°C, 50A non-repetitive surge rating, and guard ring die construction for transient protection. It serves as a low-loss freewheeling or polarity protection diode in DC-DC converters, automotive auxiliary power supplies, and high-frequency inverters.
For engineers reviewing the B2100-13 datasheet, B2100-13 pinout, B2100-13 application, or B2100-13 equivalent, this page delivers verified electrical parameters, thermal derating behavior, SMB terminal layout, and direct alternatives with documented voltage/current/thermal trade-offs.
Technical Context
This Schottky rectifier uses a planar guard ring die structure to suppress edge breakdown and improve surge robustness without compromising low VF. Its 15°C/W junction-to-terminal thermal resistance enables 2.0A continuous conduction at 125°C terminal temperature when properly heatsunk.
Designed for high-frequency switching (e.g., 100–500 kHz DC-DC stages), it exhibits 75 pF capacitance at 4V reverse bias and maintains leakage below 7.0 µA at 100V/25°C - critical for standby efficiency in energy-sensitive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before avalanche; sets upper limit for input rail clamping in 48V systems. |
| IF(AV) | 2.0 A - Average forward current at TT = +125°C; defines continuous DC output capability in thermally constrained PCB layouts. |
| VF | 0.79 V @ 2.0A, 25°C - Low conduction loss enabling >92% efficiency in 12V→5V buck converters at full load. |
| IFSM | 50 A - Single half-sine surge rating at 8.3 ms; withstands inrush into capacitive loads or motor startup transients. |
| IR | 7.0 µA @ 100V, 25°C - Minimal leakage preserves battery life in always-on automotive modules. |
| CT | 75 pF @ 4V, 1MHz - Low junction capacitance minimizes switching losses and EMI in high-frequency SMPS. |
| RθJT | 15 °C/W - Junction-to-terminal thermal resistance; enables direct thermal coupling to copper pour or heatsink tab. |
Pinout & Package
Package: SMB (Surface Mount Small Outline) - molded plastic body, UL 94V-0 rated, 0.093 g mass, lead-free matte tin terminals, cathode band polarity marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential node (e.g., switch node in buck converter); requires adequate copper area for thermal dissipation. |
| Cathode | Forward current exit / reverse blocking terminal | Marked by band or notch; ties to higher-potential rail (e.g., output capacitor positive); must maintain clearance from adjacent traces at full VRRM. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Prevents premature edge breakdown under high dv/dt, improving reliability in fast-switching flyback and LLC topologies. |
| Low VF at high temperature | 0.69 V @ 2.0A, 100°C - maintains conduction efficiency even under sustained thermal stress in enclosed enclosures. |
| High-temp solder compatibility | Rated for 260°C/10 sec reflow - compatible with standard Pb-free SMT processes without delamination risk. |
| Halogen & antimony free | Meets <900 ppm Br, <900 ppm Cl, <1000 ppm Sb - satisfies strict environmental compliance for automotive and industrial OEMs. |
Applications
| Automotive Body Control Module (BCM) | Industrial 48V DC-DC Converter |
|---|---|
Use Scenario: Reverse polarity protection on 12V/24V supply input to microcontroller-based lighting control units. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed upstream of LDOs and CAN transceivers. Use Value: 0.79V VF limits voltage drop to <0.8V at 2A, preserving headroom for downstream 3.3V logic while surviving jump-start surges. | Use Scenario: Freewheeling path in synchronous buck converter converting 48V bus to 12V for fan and pump drivers. IC Role / Device Role / Timing Role: Low-loss续流 path during high-side FET off-time; operates at ~200 kHz switching frequency. Use Value: 75 pF capacitance and 0.79V VF reduce switching losses and improve light-load efficiency over silicon PN alternatives. |
| USB-C Power Delivery Adapter | Telecom Remote Radio Unit (RRU) |
Use Scenario: Output rectification in 20V/3A GaN-based flyback stage feeding secondary-side controller. IC Role / Device Role / Timing Role: High-frequency output diode replacing synchronous rectifier where gate drive complexity is prohibitive. Use Value: 50A IFSM handles peak currents during short-circuit recovery; 100V VRRM accommodates reflected voltage spikes. | Use Scenario: Polarity protection on -48V DC backup supply input to FPGA and RF front-end ICs. IC Role / Device Role / Timing Role: Input protection diode ensuring safe hot-swap insertion and lightning-induced transient suppression. Use Value: Guard ring die withstands 50A surge without degradation; 7.0 µA IR prevents battery drain in standby mode. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SS210HE3/5AT | Same SMB package, 100V VRRM, but 0.85V VF @ 2A/25°C and 100 µA IR @ 100V/25°C. | Higher VF increases conduction loss; higher IR reduces battery hold-up time in always-on telecom modules. | Select if cost sensitivity outweighs 60 mW extra loss per diode at 2A. |
| ON Semiconductor SB2100-E3/54 | Identical 100V/2A rating, but RθJT = 18°C/W and no guard ring; 0.82V VF @ 2A/25°C. | Lower thermal performance limits continuous current to 1.7A at 125°C; reduced surge margin due to absence of guard ring. | Choose only for non-critical consumer applications with ample thermal margin and no surge exposure. |
Compared with SS210HE3/5AT and SB2100-E3/54, B2100-13 delivers superior thermal resistance (15 vs. 18°C/W), lower leakage (7 µA vs. 100 µA), and proven transient robustness via guard ring - making it preferred for automotive and industrial designs demanding long-term reliability under thermal and electrical stress.

FAQ
What is the maximum allowable junction temperature for B2100-13?
The absolute maximum junction temperature is +150°C, but continuous operation at that level is not recommended. The device is rated for 2.0A average forward current only when the terminal temperature (TT) is held at +125°C - implying a practical max junction temperature of ~140°C under typical PCB thermal conditions with 15°C/W RθJT.
Can B2100-13 be used in place of a silicon PN rectifier in a 100 kHz flyback converter?
Yes - its 75 pF capacitance and lack of reverse recovery charge make it suitable for 100 kHz flyback output rectification. Unlike PN diodes, it avoids reverse recovery losses and associated EMI, improving efficiency by 1–2% and reducing snubber requirements. Ensure layout minimizes parasitic inductance to preserve low-noise performance.
Is B2100-13 qualified to AEC-Q101 for automotive use?
No - the standard B2100-13 is not AEC-Q101 qualified. Diodes offers the automotive-grade variant B2100Q-13-F, which undergoes additional stress testing (HTOL, TCT, ESD) and is documented in a separate datasheet (DS30021Q). For automotive applications, B2100Q-13-F must be specified.
How does the guard ring die construction improve reliability?
The guard ring mitigates electric field crowding at the silicon periphery, preventing premature avalanche breakdown during high dv/dt transients. This extends operational life under repeated surge events (e.g., load dump in automotive systems) and improves consistency in high-humidity or contaminated environments where surface leakage paths could otherwise trigger failure.
