Product details
Overview
B220AQ-13-F from Diodes Incorporated is a 20 V, 2.0 A surface-mount Schottky barrier rectifier in SMA package, with maximum forward voltage of 0.50 V at 2.0 A and reverse leakage current ≤0.5 mA at 20 V, designed for polarity protection and freewheeling in low-voltage DC/DC converters and automotive body electronics.
For engineers reviewing the B220AQ-13-F datasheet, B220AQ-13-F pinout, B220AQ-13-F application, or B220AQ-13-F equivalent, key selection criteria include its 20 V VRRM rating, 0.50 V VF at full load, AEC-Q101 qualification, RoHS-compliant lead-free plating, and thermal resistance of 25 °C/W (junction-to-lead).
Technical Context
This Schottky rectifier uses guard ring die construction to suppress transient-induced failure and supports high-frequency switching up to several MHz due to low junction capacitance (200 pF at 40 V). Its low forward voltage drop directly reduces conduction loss in 3.3 V–12 V power rails.
The device operates across –65 °C to +150 °C and sustains non-repetitive surge currents up to 50 A (8.3 ms half-sine), enabling robustness in inductive load switching and automotive load-dump scenarios where peak energy absorption is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 20 V - Maximum repetitive reverse voltage before breakdown; sets upper limit for blocking capability in 12 V automotive systems. |
| IO (AV) | 2.0 A - Continuous average forward current at TA = +25°C; defines steady-state power delivery capacity in compact layouts. |
| VF (max) | 0.50 V @ 2.0 A - Forward voltage at rated current; determines conduction loss (1.0 W dissipation) and thermal design margin. |
| IR (max) | 0.5 mA @ 20 V - Reverse leakage at rated VR and +25°C; impacts standby power in always-on circuits. |
| RθJL | 25 °C/W - Junction-to-lead thermal resistance; enables direct heatsinking via PCB copper pour for sustained 2 A operation. |
| IFSM | 50 A - Non-repetitive peak forward surge current; withstands inrush and flyback energy in motor drivers and solenoid controls. |
| CT | 200 pF @ 40 V - Total junction capacitance at 1 MHz; limits high-frequency switching speed but suits <500 kHz DC/DC topologies. |
Pinout & Package
Package: SMA (DO-214AC), molded plastic case with UL 94V-0 flammability rating, cathode indicated by band on body, weight ≈0.064 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward current entry point | Connected to lower-potential side (e.g., ground or return path) in reverse-polarity protection configurations. |
| Cathode | Forward current exit point | Connected to input supply rail; cathode band identifies polarity for automated placement and manual inspection. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring die construction | Enhances ESD and transient immunity without external TVS, reducing board area and BOM count in harsh environments. |
| AEC-Q101 qualification | Validated for automotive under-hood and body control modules requiring reliability over temperature cycling and vibration. |
| Lead-free, halogen-free "Green" finish | Meets RoHS 3 and JEDEC J-STD-020 Level 1 moisture sensitivity, enabling standard reflow without baking. |
| Low VF and high efficiency | Delivers >92% efficiency at 2 A in 5 V output buck converters, minimizing thermal stress on adjacent components. |
Applications
| Automotive Body Control Module | USB-C Power Delivery Input Protection |
|---|---|
Use Scenario: Polarity reversal protection on 12 V battery-fed microcontroller power rails in door modules and seat controllers. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed between battery input and LDO/regulator input. Use Value: Prevents damage during jump-start misconnection; 0.50 V VF ensures minimal dropout and no thermal derating at ambient +85°C. | Use Scenario: Reverse-current blocking at the input of 5 V/3 A USB-C PD sink circuits. IC Role / Device Role / Timing Role: Freewheel diode preventing backfeed from output capacitors into upstream power switches during fault conditions. Use Value: 50 A IFSM handles hot-plug inrush transients; 0.5 mA IR avoids excessive standby drain in battery-powered portable devices. |
| Industrial PLC I/O Terminal | Low-Voltage DC/DC Converter Output Rectification |
Use Scenario: Re-circulating diode across 24 V solenoid coils in programmable logic controller output stages. IC Role / Device Role / Timing Role: Freewheel path for inductive kickback during switch-off of N-channel MOSFET drivers. Use Value: 25 °C/W RθJL allows direct thermal coupling to PCB copper, sustaining repeated 50 A surges without solder joint fatigue. | Use Scenario: Synchronous rectifier replacement in 3.3 V/2 A isolated flyback secondary-side rectification. IC Role / Device Role / Timing Role: Low-loss output rectifier in non-synchronous flyback or forward converter designs. Use Value: 0.50 V VF cuts conduction loss by ~40% vs. silicon diodes, improving full-load efficiency from 85% to 89% in 5 W adapters. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB220-E3/54 (Vishay) | Same 20 V VRRM, 2.0 A IO, but VF = 0.52 V (typ), RθJA = 85 °C/W (vs. 25 °C/W junction-to-lead). | Lacks AEC-Q101 qualification; not approved for automotive production. | Prefer B220AQ-13-F where automotive qualification or lower thermal resistance is required. |
| SS22 (ON Semiconductor) | 20 V VRRM, 2.0 A IO, VF = 0.55 V (max), IR = 0.2 mA (typ), but only qualified to industrial temp range (–55 °C to +125 °C). | No PPAP capability; unsuitable for Tier-1 automotive programs requiring traceable process control. | Select B220AQ-13-F when PPAP documentation, extended temperature support, or higher surge rating (50 A vs. 30 A) is mandatory. |
Compared with SB220-E3/54 and SS22, B220AQ-13-F delivers superior thermal performance (25 °C/W RθJL), certified automotive reliability (AEC-Q101 + PPAP), and higher surge tolerance-making it the preferred choice for safety-critical 12 V systems where long-term field stability is non-negotiable.

FAQ
What is the maximum operating temperature for B220AQ-13-F?
The B220AQ-13-F is rated for junction temperatures from –65 °C to +150 °C. Its thermal resistance of 25 °C/W (junction-to-lead) allows continuous 2.0 A operation at ambient temperatures up to +100 °C when mounted on ≥1 cm² of 2 oz copper, per Diodes' recommended pad layout.
Is B220AQ-13-F suitable for synchronous rectification?
No-B220AQ-13-F is a passive Schottky rectifier, not a synchronous rectifier IC. It lacks gate drive circuitry or control logic. It serves as a freewheel or blocking diode in non-synchronous topologies like flyback or buck converters where simplicity and cost outweigh efficiency gains from active switching.
Does B220AQ-13-F have a cathode notch or band marking?
Yes-the SMA package uses a cathode band marking on the body, consistent with industry-standard polarity identification. The band aligns with the cathode terminal, verified in Diodes' package outline DS38433 Rev. 3–2, page 4, and confirmed in top-view mechanical drawings.
Can B220AQ-13-F replace B230AQ-13-F in a 30 V circuit?
No-B220AQ-13-F has a 20 V VRRM rating and is not rated for 30 V reverse blocking. Using it in a 30 V system risks avalanche breakdown and premature failure. For 30 V applications, B230AQ-13-F (30 V VRRM) or B240AQ-13-F (40 V VRRM) must be selected per the voltage derating guidelines in DS38433.
