Product details
Overview
B2100-13-F from Diodes Incorporated is a 2.0A, 100V peak repetitive reverse voltage Schottky barrier rectifier in SMB package, featuring 0.79V max forward voltage at 2.0A/25°C, 50A non-repetitive surge rating, and guard ring die construction for transient protection-used in low-voltage, high-frequency inverters and polarity protection circuits.
For engineers reviewing the B2100-13-F datasheet, B2100-13-F pinout, B2100-13-F application, or B2100-13-F equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance (15°C/W junction-to-terminal), reverse leakage (7.0µA @ 100V/25°C), and SMB package compatibility with automated SMT assembly.
Technical Context
This Schottky rectifier uses a planar guard ring die structure to enhance transient voltage immunity without compromising low forward conduction loss. Its low VF (≤0.79V @ 2.0A) and low CT (75pF @ 4V) support high-efficiency, high-frequency switching in DC-DC converters and freewheeling paths.
Thermal performance is defined by RθJT = 15°C/W under terminal-heatsink conditions, enabling 2.0A average output at TJ = +125°C. The device operates across –65°C to +150°C and meets J-STD-020 Level 1 moisture sensitivity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe operating limit in polarity protection and flyback clamp applications |
| IO | 2.0 A - Average rectified current at TT = +125°C; sets continuous power handling in 12V/24V DC systems |
| VF | 0.79 V max @ 2.0A/25°C - Directly determines conduction loss (1.58W max per diode); critical for thermal budget in compact layouts |
| IFSM | 50 A - Non-repetitive surge rating (8.3ms half-sine); supports inrush and fault-current tolerance in motor drives |
| IR | 7.0 µA @ 100V/25°C - Reverse leakage magnitude affects standby power in battery-backed systems and sensing accuracy |
| RθJT | 15 °C/W - Junction-to-terminal thermal resistance; enables direct heatsinking via PCB copper or metalized pads |
| CT | 75 pF @ 4V/1MHz - Low junction capacitance minimizes switching losses and EMI in >100kHz SMPS designs |
Pinout & Package
Package: SMB (Surface-Mount Small Outline), molded plastic body with UL 94V-0 flammability rating, matte tin-plated terminals, cathode band polarity marking, and 0.093g mass.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry | Connected to lower-potential side (e.g., ground or return path) in rectification; requires low-impedance trace for surge current |
| Cathode | Forward current exit / reverse blocking node | Marked with band; ties to positive rail in polarity protection; must withstand full VRRM during reverse bias |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Improves transient voltage immunity without increasing VF-enables reliable operation in noisy industrial environments |
| Lead-free, halogen-free "Green" compliance | Meets RoHS 3 (2015/863/EU), <900ppm Br/Cl, <1000ppm Sb-supports eco-design and export compliance |
| High-temperature soldering tolerance | Rated for +260°C/10s at terminal-compatible with standard lead-free reflow profiles without degradation |
| Low thermal resistance | RθJT = 15°C/W allows direct thermal coupling to PCB copper pour or heatsink pad-reduces need for external cooling |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB2100-E3/52 (Vishay) | Same SMB package, 100V VRRM, but VF = 0.85V max @ 2A/25°C; RθJT = 18°C/W | Higher conduction loss and thermal resistance reduce efficiency in thermally constrained layouts | Prefer B2100-13-F where board space limits heatsinking or ambient exceeds +85°C |
| SS210H (ON Semiconductor) | SMB package, 100V VRRM, VF = 0.75V typ @ 2A/25°C, but IR = 10µA @ 100V/25°C (vs. 7µA) | Lower VF improves light-load efficiency, but higher leakage may impact battery-cutoff accuracy | Prefer B2100-13-F in always-on systems requiring ultra-low standby leakage |
Compared with SB2100-E3/52 and SS210H, B2100-13-F delivers the optimal balance of low VF (0.79V), low IR (7.0µA), and low RθJT (15°C/W) for thermally demanding, high-reliability 2A rectification tasks.

FAQ
What is the maximum junction temperature for continuous operation?
The B2100-13-F has an operating temperature range of –65°C to +150°C. Continuous operation at full 2.0A average current is rated at terminal temperature (TT) = +125°C, not junction temperature-actual TJ depends on PCB thermal design and ambient conditions, with RθJT = 15°C/W defining the thermal path from junction to terminal.
Is B2100-13-F suitable for automotive applications?
Yes-the B2100-13-F meets AEC-Q101 stress test requirements when used within its rated electrical and thermal limits. An automotive-qualified variant (B2100Q) is also available under a separate datasheet with full PPAP documentation and extended temperature validation.
How does the guard ring die construction improve reliability?
The guard ring structure surrounds the active Schottky junction to suppress edge breakdown under high dv/dt or transient overvoltage. This prevents localized avalanche and premature failure during load dump or ESD events-verified by Diodes' internal transient immunity testing per IEC 61000-4-5.
Can B2100-13-F be used in parallel for higher current?
Parallel operation is not recommended without individual current-sharing resistors due to VF mismatch between units. At 25°C, typical VF variation is ±5%, leading to uneven current distribution; for >2A applications, select a single higher-rated part (e.g., B3100) or verify matching with binning data from Diodes' factory.
