Product details
Overview
B220A-13 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 freewheeling paths and polarity protection circuits.
For engineers reviewing the B220A-13 datasheet, B220A-13 pinout, B220A-13 application, or B220A-13 equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance (25 °C/W junction-to-lead), peak repetitive reverse voltage (20 V), surge capability (50 A), and RoHS/Green compliance status for high-volume PCB assembly.
Technical Context
This Schottky diode employs guard ring die construction to suppress transient-induced avalanche failure and supports automated SMT placement with lead-free matte tin plating solderable per MIL-STD-202 Method 208. Its low VF enables high-efficiency operation in 3.3 V–12 V power rails.
Thermal performance is defined by RθJL = 25 °C/W (SMA), enabling 2.0 A continuous conduction at ≤125 °C ambient when mounted on FR-4 with minimum recommended pad layout. Reverse leakage remains ≤0.5 mA at 20 V and 25 °C, critical for standby power integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 20 V - Maximum repetitive reverse blocking voltage; sets upper limit for input rail protection in 12 V systems. |
| IF(AV) | 2.0 A - Continuous average forward current; supports sustained output in compact DC/DC converters. |
| VF @ 2.0 A | 0.50 V - Low conduction loss; reduces power dissipation to ≤1.0 W at full load. |
| IFSM | 50 A - Peak surge rating for 8.3 ms half-sine; handles inrush and fault transients without failure. |
| RθJL | 25 °C/W - Junction-to-lead thermal resistance; enables direct thermal coupling to PCB copper for passive cooling. |
| IR @ 20 V | 0.5 mA - Reverse leakage at rated VR and 25 °C; minimizes quiescent current in battery-backed circuits. |
| Package | SMA - Standard surface-mount outline (4.00–4.60 mm × 2.29–2.92 mm); compatible with IPC-7351B footprint. |

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, 2.0 A IF, but SMB package (RθJL = 20 °C/W); VF = 0.52 V @ 2.0 A. | Higher thermal conductivity suits higher ambient temp designs; larger footprint may conflict with dense layouts. | Select when board-level thermal management prioritizes junction cooling over space constraints. |
| SS22 | 20 V VRRM, 2.0 A IF, SMA package, but VF = 0.55 V @ 2.0 A; no AEC-Q101 qualification. | Lacks automotive qualification; suitable only for commercial-grade consumer or industrial applications. | Choose for cost-sensitive non-automotive designs where AEC-Q101 is not mandated. |
Compared with SB220-E3/52T and SS22, B220A-13 uniquely combines AEC-Q101 qualification, SMA footprint, and lowest VF (0.50 V) in its class-making it optimal for space-constrained automotive power rails requiring both reliability and efficiency.

FAQ
What is the maximum junction temperature for continuous operation of B220A-13?
The B220A-13 has an operating junction temperature range of –65 °C to +150 °C. For continuous 2.0 A conduction, thermal design must ensure TJ does not exceed 150 °C-achievable with RθJL = 25 °C/W and ≤125 °C ambient using standard FR-4 PCB copper area per Diodes' AP02001 pad layout.
Is B220A-13 suitable for use in synchronous rectification topologies?
No-B220A-13 is a passive Schottky rectifier, not a synchronous MOSFET driver or controlled switch. It functions only as a unidirectional freewheeling or clamping device. Synchronous rectification requires actively gated MOSFETs with timing control circuitry external to this component.
Does B220A-13 require derating at elevated ambient temperatures?
Yes-per Figure 4 in DS13004, the average forward current must be linearly derated above 75 °C ambient. At 125 °C ambient, IO is reduced to approximately 1.2 A. Derating is enforced by thermal resistance and junction temperature limits, not electrical parameter drift.
How does the guard ring construction improve reliability in automotive applications?
The guard ring mitigates edge breakdown during fast transients like load dump or ISO 7637-2 pulses by redistributing electric field stress away from the silicon periphery. This prevents localized avalanche multiplication and subsequent thermal runaway-extending lifetime in under-hood environments where voltage spikes exceed nominal ratings.
