Product details

Overview

BAV23SQ-7-F from Diodes Incorporated is a surface-mount, high-voltage dual switching diode in SOT23 package, rated for 250 V repetitive peak reverse voltage (V_RRM), 400 mA forward current (I_FM), and 50 ns reverse recovery time (t_RR). It serves as a fast-switching, low-leakage protection or signal routing element in DC-DC converter flyback snubbers, battery isolation circuits, and automotive body control modules.

For engineers reviewing the BAV23SQ-7-F datasheet, BAV23SQ-7-F pinout, BAV23SQ-7-F application, or BAV23SQ-7-F equivalent, key selection criteria include its AEC-Q200-qualified reliability, 100 nA reverse leakage at 200 V/25°C, dual-diode configuration with common-cathode topology, and compatibility with lead-free reflow profiles per J-STD-020 Level 1.

Technical Context

This dual diode integrates two independent, high-voltage silicon junction diodes in a single SOT23-3 package with common-cathode connection (Pin 1: Anode 1, Pin 2: Cathode, Pin 3: Anode 2). Its 250 V V_RRM and 141 V RMS rating support use in 100–200 V DC bus conditioning and transient suppression.

The device operates across –55°C to +150°C, features 5.0 pF total capacitance at 0 V, and delivers 1.0 V forward voltage at 100 mA - optimized for low-loss switching in portable power management where thermal resistance (R_θJA = 357°C/W) and leakage (<100 nA @ 200 V/25°C) are critical.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	250 V - supports clamping of transients up to 250 V peak without breakdown
I_FM	400 mA - enables continuous conduction in low-power DC-DC feedback paths and signal-level switching
t_RR	50 ns - ensures minimal switching loss in 100–500 kHz SMPS applications
I_R @ 200 V / 25°C	≤100 nA - reduces standby power drain in battery-backed systems
C_T @ 0 V / 1 MHz	≤5.0 pF - maintains signal integrity in high-frequency sensing and RF detector front-ends
P_D	350 mW - defines maximum dissipation on standard FR-4 PCB with 1"×1" copper pad
T_J Range	–55°C to +150°C - qualified for under-hood automotive and industrial control environments

Pinout & Package

Package: SOT23-3, surface-mount plastic package with matte tin-plated alloy 42 leadframe, UL 94V-0 rated, moisture sensitivity level 1.

Applications

Automotive Body Control Module (BCM)

USB Port Power Switching

Use Scenario: Isolating 12 V supply domains between lighting, wiper, and door lock subsystems.

IC Role / Device Role / Timing Role: Dual-anode, common-cathode diode provides reverse-polarity protection and load-dump clamping per channel.

Use Value: Prevents cross-conduction during hot-swap events while maintaining <100 nA leakage to preserve battery life over 10-year vehicle service life.

Use Scenario: Enabling/disabling VBUS power delivery to downstream USB peripherals in portable docking stations.

IC Role / Device Role / Timing Role: Fast-switching dual diode routes or blocks 5 V power with sub-50 ns turn-off to meet USB 2.0 timing constraints.

Use Value: Eliminates need for discrete MOSFET gate drivers by leveraging low t_RR and 1.0 V V_F at 100 mA for efficient 5 V switching.

Industrial Sensor Signal Conditioning

AC-DC Adapter Flyback Snubber

Use Scenario: Protecting analog front-end inputs of 4–20 mA loop-powered sensors from ESD and overvoltage transients.

IC Role / Device Role / Timing Role: Dual diode clamps positive/negative excursions to rail using common-cathode architecture tied to reference ground.

Use Value: 250 V V_RRM withstands IEC 61000-4-5 surge tests; 5.0 pF C_T avoids loading high-impedance sensor outputs.

Use Scenario: Suppressing voltage spikes across primary-side MOSFETs in 12–24 V output AC-DC adapters.

IC Role / Device Role / Timing Role: Fast-recovery dual diode forms part of RCD snubber network, absorbing energy during MOSFET turn-off.

Use Value: 50 ns t_RR ensures full energy transfer before secondary conduction begins, improving efficiency by >2% vs. slower diodes.

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-voltage dual switching diode applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BAV23CQ-7-F	Same package and ratings, but configured as common-anode (Pin 1: Cathode 1, Pin 2: Anode, Pin 3: Cathode 2)	Required where dual-input, single-output topology is needed (e.g., dual-rail OR-ing into shared load)	Select when circuit requires common-anode instead of common-cathode polarity
MBR0520L-7-F	Lower V_RRM (20 V), Schottky construction, 0.35 V V_F, no reverse recovery (t_RR ≈ 0 ns)	Suitable only for ≤20 V systems; cannot replace BAV23SQ-7-F in 100+ V applications	Choose only for low-voltage, ultra-low-V_F needs - not a drop-in replacement

Compared with BAV23CQ-7-F, the BAV23SQ-7-F enables common-cathode configurations essential for dual-rail clamping to ground; versus MBR0520L-7-F, it trades higher forward voltage for 12.5× higher voltage capability and robust junction-isolation in harsh environments.

FAQ

What is the pin configuration of BAV23SQ-7-F?

BAV23SQ-7-F uses a common-cathode configuration in SOT23-3: Pin 1 is Anode 1, Pin 2 is the shared Cathode, and Pin 3 is Anode 2. This layout allows independent anode routing while referencing both diodes to a single return path - confirmed in Diodes' DS30042 Rev. 23, page 4 top-view diagram.

Is BAV23SQ-7-F suitable for automotive applications?

Yes - BAV23SQ-7-F is AEC-Q200 qualified per Diodes' product definitions and meets JEDEC stress test requirements for temperature cycling, high-temperature reverse bias, and humidity testing. It is explicitly designated for automotive use, unlike the non-Q BAV23S variants.

How does BAV23SQ-7-F differ from BAV23A-7-F?

BAV23SQ-7-F is the automotive-grade version of the BAV23S-7-F, with identical electrical specs and SOT23 package but certified to AEC-Q200. BAV23A-7-F is a different variant - common-anode configuration, also automotive-qualified, and marked separately in Diodes' ordering table (DS30042 p.1).

What is the maximum operating temperature for continuous use?

The BAV23SQ-7-F has a specified operating junction temperature range of –55°C to +150°C. For continuous operation at ambient temperatures above 75°C, derating per Figure 1 (power derating curve) applies: power dissipation must be reduced linearly from 350 mW at 25°C to zero at 150°C ambient on standard FR-4 board.
