Product details
Overview
B220AE-13 from Diodes Incorporated is a 20 V, 2 A surface-mount Schottky barrier rectifier in SMA package with maximum forward voltage of 0.50 V at 2 A and reverse leakage current of 0.1 mA at 20 V and +25°C, optimized for boost, blocking, and recirculating diode roles in DC-DC converters and power supplies.
For engineers reviewing the B220AE-13 datasheet, B220AE-13 pinout, B220AE-13 application, or B220AE-13 equivalent, key selection criteria include low VF for efficiency, high-temperature IR stability, SMA thermal resistance (95°C/W), RoHS/Green compliance, and 50 A surge rating-critical for compact, thermally constrained power designs.
Technical Context
This Schottky rectifier uses a planar metal-semiconductor junction to achieve low forward voltage drop and fast switching with no minority-carrier storage delay. Its 20 V VRRM rating targets low-voltage DC-DC stages where conduction loss dominates over reverse recovery losses.
Thermal design is enabled by its SMA package with 95°C/W junction-to-ambient resistance and 45°C/W junction-to-case resistance. Reverse leakage remains stable up to +150°C, supporting operation in automotive under-hood and industrial power modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 20 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for input/output voltage rails in buck/boost topologies. |
| IO(AV) | 2 A - Average rectified output current at TA = +25°C; derates to ~1.2 A at +100°C per Figure 4. |
| VF(MAX) | 0.50 V @ 2 A, +25°C - Low conduction loss enables >95% efficiency in 3.3–5 V output converters. |
| IR(MAX) | 0.1 mA @ 20 V, +25°C - Minimal leakage preserves standby power in always-on systems. |
| IFSM | 50 A - Non-repetitive surge rating supports inrush current handling during cold start or load transients. |
| RθJA | 95 °C/W - Thermal resistance on FR-4 board defines minimum copper area needed for thermal management. |
Pinout & Package
SMA (DO-214AC) surface-mount package: molded plastic body, cathode band marking, matte tin-plated copper leadframe, UL 94V-0 rated, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Input current terminal | Connected to source-side node (e.g., switch node in boost, input rail in blocking configuration). |
| Cathode | Output current terminal | Connected to output rail or return path; marked by band; carries full IO current with minimal voltage drop. |
Key Features
| Feature | Design Value |
|---|---|
| Low VF at high current | 0.50 V max @ 2 A ensures <1 W conduction loss in 5 V/2 A applications, reducing heatsink need. |
| Stable high-temp IR | Leakage stays ≤0.1 mA at +25°C and remains controlled up to +150°C, preventing thermal runaway in sealed enclosures. |
| RoHS & Green compliant | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb); meets EU directives and automotive material requirements. |
| SMA mechanical robustness | 0.063 g weight and 94V-0 flammability rating support reliability in vibration-prone industrial PCBs. |
Applications
| Boost Diode | Blocking Diode |
|---|---|
Use Scenario: Step-up converter in USB PD power banks delivering 9–20 V from 3.7 V Li-ion battery. IC Role / Device Role / Timing Role: Unidirectional current path from switch node to output capacitor; blocks reverse current during low-side FET conduction. Use Value: 0.5 V VF minimizes voltage headroom loss, enabling higher output regulation accuracy and efficiency above 92%. |
Use Scenario: Solar charge controller isolating PV panel from battery during nighttime or low-light conditions. IC Role / Device Role / Timing Role: Prevents battery discharge through panel; operates continuously at ambient temperatures up to +85°C. Use Value: 0.1 mA IR at +25°C and stable leakage at elevated temperature reduce parasitic night-time drain by >95% vs. standard PN diodes. |
| Recirculating Diode | OR-ing Diode |
Use Scenario: Flyback energy recovery in brushed DC motor drivers controlling industrial actuators. IC Role / Device Role / Timing Role: Provides low-loss path for inductive kickback current when H-bridge low-side switches turn off. Use Value: Fast recovery (no stored charge) and 50 A IFSM withstand repeated 10 A transient surges without degradation. |
Use Scenario: Dual-input power redundancy in telecom base station backplane with 5 V and 3.3 V rails. IC Role / Device Role / Timing Role: Enables seamless switchover between sources while minimizing forward drop and cross-conduction risk. Use Value: Low VF ensures <50 mV voltage difference between inputs, simplifying control logic and improving system uptime. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS22 (Micro Commercial) | Same 20 V/2 A rating, but VF = 0.55 V max @ 2 A; RθJA = 100°C/W; SMB package only. | Larger footprint and higher thermal resistance limit use in space-constrained layouts. | Select if SMB compatibility required and 50 mV VF penalty acceptable for cost-sensitive designs. |
| SB220 (ON Semiconductor) | Identical SMA package and 20 V/2 A rating; VF = 0.52 V max @ 2 A; IR = 0.2 mA @ 20 V, +25°C. | Higher leakage reduces suitability for ultra-low-power standby circuits. | Prefer for legacy designs already qualified with ON Semi's SB220; verify leakage impact in battery-backed systems. |
Compared with SS22 and SB220, B220AE-13 delivers the lowest VF (0.50 V) and tightest IR (0.1 mA), making it optimal for thermally limited, high-efficiency, and low-standby-power applications where SMA fit is mandatory.

FAQ
What is the maximum operating temperature for B220AE-13?
The B220AE-13 has an operating junction temperature range of –55°C to +150°C. Its reverse leakage remains stable up to +150°C, and thermal resistance (RθJA = 95°C/W) allows safe operation at full 2 A current with adequate PCB copper area at ambient temperatures up to +85°C.
Is B220AE-13 compatible with lead-free reflow soldering?
Yes. B220AE-13 features a matte tin annealed finish over copper leadframe and is rated for lead-free reflow per JEDEC J-STD-020. It meets IPC/JEDEC J-STD-020 moisture sensitivity level 1, requiring no baking prior to assembly.
How does B220AE-13 differ from B220BE-13?
B220AE-13 uses the SMA (DO-214AC) package (2.29–2.92 mm width), while B220BE-13 uses the larger SMB (DO-214AA) package (3.30–3.94 mm width). Both share identical electrical specs, but SMA offers lower profile and slightly higher RθJA (95 vs. 90°C/W), favoring height-constrained designs.
Can B220AE-13 replace a standard PN rectifier like 1N4001?
No. B220AE-13 is a Schottky device with 20 V VRRM and no reverse recovery time, whereas 1N4001 is a 50 V PN rectifier with slow recovery and higher VF (~1.1 V). Substitution requires verifying voltage margin, thermal design, and circuit timing-B220AE-13 is unsuitable for AC line rectification.
