Product details

Overview

B220Q-13-F from Diodes Incorporated is a 2.0A, 20V peak repetitive reverse voltage (V_RRM) surface-mount Schottky barrier rectifier in SMB package, with maximum forward voltage of 0.50 V at 2.0 A and reverse leakage current ≤0.5 mA at 25°C, designed for polarity protection and freewheeling in low-voltage DC/DC converters and automotive power rails.

For engineers reviewing the B220Q-13-F datasheet, B220Q-13-F pinout, B220Q-13-F application, or B220Q-13-F equivalent, key selection criteria include its 20 V blocking rating, low 0.50 V forward drop at rated current, AEC-Q101 qualification, SMB thermal resistance (R_θJA = 80 °C/W), and 50 A non-repetitive surge capability - all critical for high-efficiency, space-constrained 12 V system designs.

Technical Context

This Schottky rectifier uses guard ring die construction to enhance transient immunity and suppress avalanche-induced failure during inductive switching events. Its low forward voltage and fast recovery (inherently <10 ns due to majority-carrier conduction) minimize conduction and switching losses in high-frequency (<1 MHz) topologies.

The device operates across –65 °C to +150 °C junction temperature, with thermal resistance from junction to ambient (80 °C/W on FR-4) and junction to lead (20 °C/W), enabling reliable operation under sustained 2.0 A DC load with appropriate PCB copper area.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	20 V - Maximum DC or peak AC reverse voltage the diode blocks without breakdown; sets usable input range in 12 V systems.
I_O	2.0 A - Continuous average forward current at +25°C ambient; derates to ~1.2 A at +100°C per Fig. 4.
V_F max	0.50 V @ 2.0 A - Low conduction loss enables >92% efficiency in 5–12 V buck converter outputs.
I_R max	0.5 mA @ 20 V, 25°C - Minimal leakage preserves battery standby time in always-on automotive modules.
I_FSM	50 A @ 8.3 ms - Withstands motor startup surges and relay coil de-energization transients.
C_T	200 pF @ 40 V, 1 MHz - Low junction capacitance limits high-frequency switching noise and EMI generation.

Pinout & Package

SMB (DO-214AA) surface-mount package: molded plastic case, UL 94V-0 rated, cathode indicated by band on body; terminals are matte tin-plated for RoHS-compliant solderability.

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.
Cathode	Forward current exit point / reverse-blocking terminal	Connected to positive rail; blocks reverse current flow when input polarity is inverted.

Key Features

Feature	Design Value

Applications

Automotive Body Control Module (BCM)

USB-C Power Delivery Input Protection

Use Scenario: Reverse polarity protection on 12 V supply input to BCM microcontroller and CAN transceiver circuitry.

IC Role / Device Role / Timing Role: Unidirectional blocking diode placed in series with main power rail to prevent damage from battery misconnection.

Use Value: 0.50 V forward drop minimizes voltage loss at 2.0 A peak load, preserving brown-out margin for 5 V LDOs downstream.

Use Scenario: Input-side freewheeling diode in 20 V/3 A USB PD buck-boost front-end stage.

IC Role / Device Role / Timing Role: Freewheel path for inductor current during high-side switch off-time in synchronous rectification.

Use Value: 200 pF capacitance and fast majority-carrier response reduce switching node ringing and EMI emissions at 300–500 kHz.

Industrial PLC I/O Power Rail

LED Driver Return Path Protection

Use Scenario: Polarity protection for 24 V DC field power inputs to digital input modules subject to wiring errors.

IC Role / Device Role / Timing Role: Series-connected blocking diode ensuring safe operation even if field wiring is reversed.

Use Value: 50 A surge rating withstands accidental short-circuit transients during hot-plug connector mating.

Use Scenario: Reverse-current blocking in constant-current LED string return path to prevent backfeed into auxiliary supplies.

IC Role / Device Role / Timing Role: Blocking diode isolating LED sink driver output from shared ground return paths.

Use Value: 0.5 mA max leakage at 25°C prevents unintended LED glow during standby mode in multi-string lighting arrays.

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 (Vishay)	Same SMB package, 20 V V_RRM, but VF = 0.55 V @ 2.0 A and IR = 1.0 mA @ 25°C.	Higher leakage may impact ultra-low-power sleep modes; slightly higher conduction loss reduces efficiency by ~0.3% at full load.	Select if Vishay's qualification documentation or long-term supply agreement is required.
SS22 (ON Semiconductor)	SMB package, 20 V V_RRM, VF = 0.52 V @ 2.0 A, IR = 0.5 mA @ 25°C, but not AEC-Q101 qualified.	Lacks automotive stress validation; unsuitable for under-hood or safety-critical modules requiring PPAP.	Acceptable for industrial or consumer-grade 12 V supplies where automotive qualification is not mandated.

Compared with SB220-E3/52T and SS22, B220Q-13-F delivers tighter leakage control and automotive-grade reliability at identical V_RRM/I_O, making it the preferred choice for AEC-Q101–compliant designs where low standby loss and surge robustness are prioritized.

FAQ

What is the maximum junction temperature for continuous operation of B220Q-13-F?

The specified operating junction temperature range is –65 °C to +150 °C. For continuous 2.0 A DC operation, thermal design must ensure junction temperature remains ≤150 °C using the R_θJA = 80 °C/W rating and actual board layout; typical derated current at +100 °C ambient is ~1.2 A per Fig. 4.

Is B220Q-13-F compatible with lead-free reflow soldering profiles?

Yes - B220Q-13-F features matte tin-plated terminals and is qualified to JEDEC J-STD-020 Level 1 moisture sensitivity. It supports standard lead-free reflow profiles up to 260 °C peak, with no pre-bake required, per Diodes Incorporated packaging specifications.

Does B220Q-13-F have a defined reverse recovery time (t_rr)?

No - as a Schottky barrier rectifier, B220Q-13-F conducts via majority carriers only and exhibits no minority-carrier storage delay. Its effective switching is limited only by junction capacitance (200 pF) and package inductance, enabling sub-nanosecond turn-off behavior in practical circuits.

Can B220Q-13-F be used in parallel for higher current handling?

Not recommended without external balancing - Schottky forward voltage has negative temperature coefficient, causing current hogging. Parallel operation requires matched V_F bins and individual series resistors (≥50 mΩ) to ensure thermal stability and current sharing under load.
