Product details
Overview
B220A-13-F from Diodes Incorporated is a 20 V, 2.0 A surface-mount Schottky barrier rectifier in SMA package, featuring 0.50 V forward voltage at 2.0 A, 50 A non-repetitive surge rating, and AEC-Q101 qualification for automotive-grade reliability-used in low-voltage DC/DC converter output rectification and reverse-polarity protection circuits.
For engineers reviewing the B220A-13-F datasheet, B220A-13-F pinout, B220A-13-F application, or B220A-13-F equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance (25 °C/W junction-to-lead), peak repetitive reverse voltage margin, and RoHS-compliant lead-free plating compatibility with automated SMT assembly.
Technical Context
This Schottky diode employs guard ring die construction to suppress transient-induced avalanche breakdown and supports high-frequency switching up to several MHz due to low junction capacitance (200 pF at 40 V). Its low VF enables reduced conduction loss in 3.3 V and 5 V power rails.
Designed for operation from –65 °C to +150 °C, it maintains stable leakage current (<0.5 mA at 20 V, 25 °C) and derates linearly above 75 °C ambient per Fig. 4-enabling use in under-hood automotive modules and industrial power supplies without forced cooling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 20 V - Maximum allowable reverse voltage before breakdown; sets safe operating limit for 12 V system input clamping and 5 V rail freewheeling. |
| IF(AV) | 2.0 A - Continuous DC forward current capability at TA = 25 °C; defines minimum trace width and copper area needed on PCB. |
| VF @ 2.0 A | 0.50 V - Forward voltage drop at full rated current; determines 1.0 W conduction loss per diode in parallel-output configurations. |
| IFSM | 50 A - Single half-sine surge rating (8.3 ms); withstands inrush into capacitive loads without failure. |
| RθJL | 25 °C/W - Junction-to-lead thermal resistance; enables direct heatsinking via PCB copper pour under cathode pad. |
| IR @ 20 V | 0.5 mA max - Reverse leakage at rated VR and 25 °C; ensures minimal standby power loss in battery-backed systems. |
| CT @ 40 V | 200 pF - Junction capacitance at 40 V bias; limits high-frequency switching noise and EMI in >100 kHz SMPS designs. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with UL 94V-0 flammability rating, matte tin-plated terminals, cathode band polarity marking, and 0.064 g typical weight.
| 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; ties to output rail or ground return; serves as primary thermal path to PCB via exposed metal pad. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Suppresses edge avalanche during voltage transients-eliminates need for external TVS in 12 V automotive load-dump protection. |
| Lead-free, RoHS-compliant finish | Matte tin plating meets MIL-STD-202 solderability requirements and supports Pb-free reflow profiles up to 260 °C/10 s. |
| AEC-Q101 qualification | Validated for automotive under-hood applications including engine control units and body electronics modules. |
| Low thermal resistance (RθJL = 25 °C/W) | Enables >1.5 W power dissipation with 75 °C temperature rise over ambient using standard 1 oz copper pad. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Adapter |
|---|---|
Use Scenario: Reverse-polarity input protection on 12 V supply rail feeding microcontroller and CAN transceiver. IC Role / Device Role / Timing Role: Unidirectional blocking diode preventing damage from incorrect battery connection.

IC Role / Device Role / Timing Role: Clamping diode absorbing inductive kickback energy during relay coil de-energization. Use Value: 50 A IFSM rating handles repeated 30 A surges without degradation-extending field service life beyond 10 years. | Use Scenario: Secondary-side rectification in constant-current LED driver powering 12 V string of 3× high-brightness LEDs. IC Role / Device Role / Timing Role: Main output rectifier in quasi-resonant flyback topology operating at 65 kHz. Use Value: <0.5 mA IR at 20 V ensures <10 µW standby leakage-critical for meeting Energy Star Tier 2 no-load power requirements. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB220-E3/52T | Same 20 V VRRM and 2.0 A IF(AV), but SMB package (RθJL = 20 °C/W) and higher VF (0.52 V typ). | Slightly better thermal performance but larger footprint; less suitable for space-constrained SMA layouts. | Select when board layout allows SMB and junction temperature margin is critical over footprint size. |
| SS22 | 20 V VRRM, 2.0 A IF(AV), but VF = 0.55 V max at 2 A and no AEC-Q101 qualification. | Not qualified for automotive use; acceptable only in commercial-grade consumer power adapters. | Choose only for cost-sensitive non-automotive applications where AEC-Q101 compliance is not required. |
Compared with SB220-E3/52T and SS22, B220A-13-F delivers the lowest VF in SMA form factor with automotive qualification-making it optimal for compact, thermally constrained, and safety-critical 12 V systems where every millivolt of conduction loss matters.

FAQ
What is the maximum junction temperature for continuous operation?
The B220A-13-F has an operating junction temperature range of –65 °C to +150 °C. For continuous DC operation at 2.0 A, thermal design must ensure TJ does not exceed 150 °C-achievable with RθJL = 25 °C/W and ≤75 °C ambient when using recommended pad layout per AP02001.
Is B220A-13-F compatible with lead-free reflow processes?
Yes-B220A-13-F features matte tin plating qualified to MIL-STD-202, Method 208, and supports lead-free reflow profiles up to 260 °C for 10 seconds, matching IPC/JEDEC J-STD-020 moisture sensitivity Level 1 requirements.
Does this part have automotive qualification documentation available?
Yes-B220A-13-F is AEC-Q101 qualified. Full PPAP documentation, test reports, and qualification summary are available upon request through Aetrix Electronics' technical support team for qualified OEM accounts.
How does its leakage current compare at elevated temperatures?
At 100 °C and rated 20 V reverse voltage, IR is specified ≤20 mA-significantly higher than the 0.5 mA max at 25 °C. This increase is inherent to Schottky physics and must be accounted for in battery-powered systems operating near thermal limits.
