Product details
Overview
B2100A-13-F from Diodes Incorporated is a 100 V, 2.0 A Schottky barrier rectifier in SMA package, featuring 0.79 V max forward voltage at 2.0 A and 0.5 mA max reverse leakage at 100 V/25°C. It delivers low power loss and high efficiency for DC-DC conversion, boost diode, and polarity protection circuits in industrial power supplies and automotive auxiliary systems.
For engineers reviewing the B2100A-13-F datasheet, B2100A-13-F pinout, B2100A-13-F application, or B2100A-13-F equivalent, key selection criteria include its 50 A non-repetitive surge rating, 125°C maximum junction temperature, RoHS-compliant matte tin finish, and verified performance under high-frequency switching and thermal stress conditions.
Technical Context
This discrete Schottky rectifier uses guard ring die construction to enhance transient voltage immunity and suppress avalanche-induced failure. Its low VF (0.69 V typ at 100°C) and stable IR (15 mA max at 100 V/100°C) enable reliable operation in thermally constrained environments without forced cooling.
The device exhibits 75 pF typical junction capacitance at 4 V reverse bias and 1 MHz, supporting efficient high-frequency rectification up to several hundred kHz. Thermal resistance from junction to terminal is 25°C/W, enabling direct PCB heat sinking in compact layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse blocking voltage; defines safe DC or peak AC voltage limit before breakdown |
| IO | 2.0 A - Average forward current rating at 25°C ambient; derates to ~1.0 A at 100°C per Figure 4 |
| VF (max) | 0.79 V @ 2.0 A, 25°C - Directly determines conduction loss; contributes <1.6 W dissipation at full load |
| IRM (max) | 0.5 mA @ 100 V, 25°C - Low leakage preserves efficiency in standby and light-load modes |
| IFSM | 50 A @ 8.3 ms - Withstands brief inrush or fault currents without permanent degradation |
| TJ max | +125°C - Enables operation in sealed enclosures or near heat-generating components |
| RθJT | 25°C/W - Allows estimation of junction temperature rise above terminal temperature for thermal design |
Pinout & Package
Package: SMA (DO-214AC), surface-mount, low-profile plastic case with cathode band marking. Dimensions: 4.0–4.6 mm length × 2.29–2.92 mm width × 1.27–1.63 mm height (per AP02002).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., switch node in boost topology); requires low-inductance layout |
| Cathode | Forward current exit / reverse voltage reference | Marked by band; ties to output rail or ground return; serves as primary thermal path to PCB copper |
Key Features

| High-temperature solderability | Rated for 260°C/10 s reflow, compatible with standard lead-free assembly processes |
Applications
| Boost Diode in DC-DC Converters | Blocking Diode in Solar Charge Controllers |
|---|---|
Use Scenario: Used in step-up converter topologies to isolate input from output during switch-off phase while conducting inductive energy transfer. IC Role / Device Role / Timing Role: Unidirectional current valve with nanosecond switching; replaces slower PN diodes to reduce switching losses. Use Value: 0.79 V VF minimizes conduction loss at 2 A, increasing overall converter efficiency by ~1.5% vs. comparable 1N5822. | Use Scenario: Prevents reverse current flow from battery to PV panel at night or under low-light conditions. IC Role / Device Role / Timing Role: Reverse-biased isolation element; must sustain 100 V DC with sub-mA leakage to avoid battery drain. Use Value: 0.5 mA IR max at 25°C ensures <1.2 mAh/day self-discharge in 12 V systems, extending battery runtime. |
| Free-Wheeling Diode in Motor Drivers | Polarity Protection in Industrial Power Inputs |
Use Scenario: Provides current recirculation path for inductive loads (e.g., solenoids, BLDC motor phases) when drive switches turn off. IC Role / Device Role / Timing Role: Fast-recovery path suppressing voltage spikes; operates in repetitive 10–100 kHz PWM cycles. Use Value: Absence of reverse recovery charge (Qrr ≈ 0) eliminates snubber requirements and EMI generation. | Use Scenario: Placed in series with main DC input to block damage from accidental reverse connection of 24 V or 48 V supply lines. IC Role / Device Role / Timing Role: Series protection element; conducts only during correct polarity, blocking >100 V reverse. Use Value: 100 V VRRM provides 2× margin over 48 V nominal systems, ensuring long-term reliability under line surges. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB2100-E3/52T | Same 100 V/2 A rating; VF = 0.85 V max @ 2 A; slightly higher RθJT (30°C/W) | Higher VF increases conduction loss by ~0.12 W at full load; less suitable for thermally tight designs | Select if legacy Vishay footprint compatibility required; verify thermal margin with 5°C/W higher junction rise |
| SS210H | 100 V/2 A; VF = 0.83 V max @ 2 A; 150°C TJ max; SMA package with same pinout | Higher temperature rating enables use in hotter environments (e.g., under-hood automotive); identical layout | Preferred for extended temperature applications; otherwise functionally interchangeable with B2100A-13-F |
Compared with SB2100-E3/52T and SS210H, the B2100A-13-F offers the lowest VF (0.79 V) and best thermal resistance (25°C/W), making it optimal for space-constrained, efficiency-critical 2 A rectification where ambient stays below 100°C.

FAQ
What is the maximum allowable junction temperature for B2100A-13-F?
The absolute maximum junction temperature is +125°C, as specified in the Electrical Characteristics table. Operation beyond this limit risks irreversible parametric shift or bond wire failure. Derating curves in Figure 4 show average forward current drops to ~1.0 A at 100°C ambient, assuming standard PCB copper area for heat spreading.
Is B2100A-13-F suitable for use in automotive under-hood applications?
It meets AEC-Q200 stress test requirements for temperature cycling and humidity exposure but is not AEC-Q101 qualified. For non-safety-critical under-hood functions like cabin lighting or HVAC control, it is widely deployed-however, engine control modules require AEC-Q101-certified alternatives such as the SB2100-AU.
How does the guard ring construction improve reliability?
The guard ring surrounds the active Schottky junction to distribute electric field gradients at the silicon edge, preventing premature avalanche breakdown during voltage transients. This extends device lifetime in applications exposed to load dump or inductive kick events, especially when used without clamping diodes or TVS devices.
Can B2100A-13-F replace a 1N5819 in existing designs?
Yes-both are SMA-packaged 1 A/40 V Schottkys-but B2100A-13-F has higher voltage rating (100 V vs. 40 V) and current (2 A vs. 1 A). Substitution requires verifying that the 100 V rating matches system requirements and that PCB pad layout accommodates identical SMA dimensions; no circuit redesign is needed for forward conduction paths.
