Product details
Overview
B2100AE-13 from Diodes Incorporated is a 100 V, 2.0 A high-voltage Schottky barrier rectifier in SMA package, optimized for low forward voltage drop (0.79 V @ 2.0 A, 25°C), low leakage current (7 µA @ 100 V, 25°C), and high-frequency freewheeling in DC-DC converters and polarity protection circuits.
For engineers reviewing the B2100AE-13 datasheet, B2100AE-13 pinout, B2100AE-13 application, or B2100AE-13 equivalent, key selection criteria include reverse voltage rating, thermal resistance (RθJA = 110°C/W), junction capacitance (70 pF @ 4 V), guard ring die construction for transient robustness, and RoHS-compliant lead-free plating.
Technical Context
This Schottky rectifier uses a planar guard ring die structure to suppress edge breakdown and improve surge immunity under repetitive transients. Its low forward voltage enables high efficiency in low-voltage, high-current paths where conduction loss dominates.
Designed for surface-mount automated assembly, it operates across –65°C to +150°C with specified derating above 25°C ambient. Junction-to-ambient thermal resistance of 110°C/W (SMA) supports reliable power dissipation up to 2.0 A DC under controlled PCB layout conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 100 V - Maximum repetitive reverse voltage before breakdown; sets safe blocking margin in 48 V or 60 V bus applications. |
| IO | 2.0 A - Average rectified output current; defines continuous DC current handling capability at 25°C ambient. |
| VF Max | 0.79 V @ 2.0 A, 25°C - Low conduction loss enables >92% efficiency in 5 V–12 V DC-DC outputs. |
| IR Max | 7 µA @ 100 V, 25°C - Minimal leakage preserves battery life in always-on polarity protection circuits. |
| CT | 70 pF @ 4 V, 1 MHz - Low junction capacitance minimizes switching loss and EMI in high-frequency (>100 kHz) inverters. |
| RθJA | 110°C/W - Thermal resistance determines required copper area for 2.0 A operation without exceeding 150°C junction temperature. |
Pinout & Package
Package: SMA (DO-214AC), surface-mount plastic case with cathode band marking; dimensions: 2.29–2.92 mm (A) × 4.00–4.60 mm (B) × 1.27–1.63 mm (C); weight ≈ 0.063 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry point during forward conduction | Connected to lower-potential side (e.g., ground or return path) in freewheeling or reverse polarity protection configurations. |
| Cathode | Current exit point during forward conduction; marked by band | Connected to higher-potential rail (e.g., input supply or switch node); blocks reverse current flow when biased negatively. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge avalanche, enabling stable 100 V blocking with 50 A non-repetitive surge tolerance (8.3 ms half-sine). |
| Low VF / high IO ratio | Delivers 2.0 A average current with <0.79 V drop-reducing power loss to ≤1.58 W at full load. |
| RoHS-compliant matte tin plating | Ensures solderability per MIL-STD-202 Method 208 and compatibility with lead-free reflow profiles (J-STD-020 Level 1). |
| Green molding compound (UL 94V-0) | Halogen- and antimony-free formulation (<900 ppm Br/Cl, <1000 ppm Sb) meets environmental compliance mandates. |
Applications
| DC-DC Converter Freewheeling Diode | Polarity Protection in 12 V Automotive ECUs |
|---|---|
Use Scenario: Placed across synchronous buck converter's low-side switch to recirculate inductor current during off-time. IC Role / Device Role / Timing Role: Freewheeling diode providing low-loss current path during MOSFET off-state; operates at switching frequency (100–500 kHz). Use Value: 0.79 V VF reduces conduction loss vs. silicon diodes, improving converter efficiency by ~3–5% at 2 A load. | Use Scenario: Connected in series with power input to prevent damage from reverse battery connection in engine control units. IC Role / Device Role / Timing Role: Blocking diode that conducts only during correct polarity; remains reverse-biased under fault condition. Use Value: 7 µA leakage at 12 V ensures negligible standby drain-critical for battery-backed modules with multi-year quiescent life. |
| AC-DC Output Rectification (24 V SMPS) | Reverse Voltage Clamping in Industrial PLC I/O Modules |
Use Scenario: Secondary-side rectifier in isolated flyback or forward converter delivering regulated 24 V output. IC Role / Device Role / Timing Role: Output rectifier conducting unidirectional current from transformer secondary; handles continuous 2.0 A DC load. Use Value: 100 V VRRM provides 4× safety margin over 24 V output, accommodating reflected transients and line surges. | Use Scenario: Used as clamping diode across relay coils or solenoid drivers to suppress inductive kickback in programmable logic controller outputs. IC Role / Device Role / Timing Role: Transient suppression diode conducting brief high-current spikes (≤50 A, 8.3 ms) during coil de-energization. Use Value: Guard ring die withstands repetitive 50 A surge events without degradation-ensuring long-term reliability in cyclic industrial loads. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS210H-TP (Micro Commercial) | Same 100 V / 2.0 A rating; VF = 0.85 V @ 2.0 A (higher conduction loss); RθJA = 125°C/W (worse thermal performance). | Suitable for cost-sensitive, lower-efficiency designs where 60 mW extra loss is acceptable. | Select if budget constraints outweigh efficiency and thermal margin requirements. |
| SB2100 (ON Semiconductor) | Identical 100 V / 2.0 A specs; VF = 0.82 V @ 2.0 A; SMB package (RθJA = 100°C/W) offers better thermal dissipation but larger footprint. | Better suited for thermally constrained layouts needing lower junction rise, but requires SMB pad revision. | Choose when board space allows SMB and thermal headroom is prioritized over compact SMA size. |
Compared with SS210H-TP and SB2100, B2100AE-13 delivers the lowest forward voltage (0.79 V) in SMA form factor, balancing efficiency, thermal performance (110°C/W), and PCB area-making it optimal for space-constrained, high-efficiency 2 A rectification.

FAQ
What is the maximum junction temperature for B2100AE-13?
The absolute maximum junction temperature is +150°C, with operating range specified from –65°C to +150°C. At 2.0 A DC load and 25°C ambient, junction temperature rise is calculated as 110°C/W × 1.58 W ≈ 174°C-exceeding limit; thus, derating or heatsinking is required per Figure 4.
Is B2100AE-13 suitable for use in automotive under-hood applications?
Yes-its –65°C to +150°C operating range, AEC-Q200 stress test alignment (per Diodes' qualification program), and robust guard ring die make it appropriate for engine control, body electronics, and ADAS power stages where transient immunity and thermal stability are critical.
How does the guard ring die construction improve reliability?
The guard ring mitigates electric field crowding at the silicon periphery, preventing premature edge breakdown under high reverse bias or surge conditions. This extends device lifetime in applications exposed to load dump transients or repetitive inductive switching events.
Can B2100AE-13 replace a standard silicon rectifier in an existing design?
Yes-if the circuit operates below 100 V reverse voltage and benefits from lower VF. However, note its higher reverse leakage (µA vs. nA for silicon) and absence of soft recovery; verify no unintended turn-on in high-dv/dt environments or sensitive analog sections.
