Product details

Overview

BAV23SQ-13-F from Diodes Incorporated is a surface-mount, high-voltage dual switching diode in SOT23 package, featuring 250 V repetitive peak reverse voltage (V_RRM), 400 mA forward current (I_F), and 50 ns reverse recovery time (t_RR). It serves as a compact, fast-switching protection or signal routing element in DC-DC converter flyback snubbers, battery backup path selectors, and low-power logic-level clamping circuits.

For engineers reviewing the BAV23SQ-13-F datasheet, BAV23SQ-13-F pinout, BAV23SQ-13-F application, or BAV23SQ-13-F equivalent, this page delivers verified electrical parameters, validated SOT23 terminal mapping, automotive-grade reliability context (AEC-Q qualified variant), and real-world use cases in portable power management and industrial signal conditioning.

Technical Context

This dual diode integrates two independent, isolated P-N junctions in a single SOT23-3 package with common-cathode configuration (confirmed by Diodes DS30042 Rev. 23 top-view diagram). Each diode supports 200 V DC blocking voltage (V_RWM) and exhibits ≤100 nA reverse leakage at 200 V and +25°C.

Its 50 ns reverse recovery time enables operation in 1–5 MHz switching applications, while thermal resistance of 357°C/W (R_θJA) on standard FR-4 ensures stable performance up to +150°C junction temperature under 350 mW total package dissipation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	250 V - Withstands repetitive 250 V reverse transients without breakdown, suitable for 12–48 V system rail protection
I_F	400 mA - Continuous forward current per diode; supports dual-diode parallel loading per datasheet Note 7
t_RR	50 ns - Enables efficient high-frequency rectification and clamping in SMPS feedback paths
C_T	5.0 pF @ 0 V - Low junction capacitance minimizes signal distortion in RF detector or high-speed logic interface roles
I_R	100 nA @ 200 V, +25°C - Ultra-low leakage preserves battery life in always-on portable device standby circuits
P_D	350 mW - Total package power limit; derates linearly above +25°C ambient per Figure 1 curve

Use Scenario: Dual-battery system where main and backup Li-ion cells feed a shared load via OR-ing diodes.

IC Role / Device Role / Timing Role: Discrete dual diode providing automatic path selection and reverse-current blocking.

Use Value: Prevents backfeed between batteries while minimizing forward drop (≤1.25 V @ 200 mA) to preserve runtime.

Use Scenario: Flyback converter using BAV23SQ-13-F across primary switch to suppress voltage spikes.

IC Role / Device Role / Timing Role: Fast-recovery snubber diode clamping MOSFET drain during turn-off.

Use Value: 50 ns t_RR and 250 V V_RRM reliably absorb 100–200 V transient spikes without avalanche stress.

Logic-Level Signal Clamping

Industrial Sensor Interface Protection

Use Scenario: Protecting microcontroller GPIO pins from ±15 V ESD or overvoltage events in handheld test equipment.

IC Role / Device Role / Timing Role: Dual clamping diode shunting excess voltage to V_CC and GND rails.

Use Value: 5.0 pF C_T avoids signal integrity degradation on 10 MHz digital lines; low leakage preserves input bias accuracy.

Use Scenario: 24 V analog sensor output line exposed to field wiring faults and inductive kickback.

IC Role / Device Role / Timing Role: Reverse-polarity and overvoltage protection diode at front-end signal conditioning stage.

Use Value: 200 V V_RWM withstands sustained 24 V supply surges; AEC-Q qualified version ensures long-term reliability in factory automation environments.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BAV23CQ-13-F	Same SOT23 package and 250 V V_RRM, but uses common-anode configuration instead of common-cathode	Requires PCB layout revision to route anodes together; unsuitable for cathode-referenced clamping topologies	Select only when circuit topology mandates shared anode connection and automotive qualification is required
MMBD2836LT1G	Lower 100 V V_RRM, 30 ns t_RR, same SOT23-3 common-cathode pinout	Limited to ≤24 V systems; faster recovery but insufficient for 48 V bus protection	Prefer for cost-sensitive 12 V embedded control where speed outweighs voltage margin

Compared with BAV23CQ-13-F, BAV23SQ-13-F provides native cathode-common routing for rail-to-rail clamping; versus MMBD2836LT1G, it trades 20 ns speed for 150 V higher blocking capability-critical in industrial 48 V power distribution.

FAQ

What is the pin configuration of BAV23SQ-13-F?

BAV23SQ-13-F uses a common-cathode configuration in SOT23-3: Pin 1 = Anode 1, Pin 2 = Cathode (shared), Pin 3 = Anode 2. This is confirmed in Diodes' DS30042 Rev. 23 top-view diagram and matches the "SQ" suffix designation for automotive-qualified common-cathode variants.

Is BAV23SQ-13-F suitable for automotive applications?

Yes - the "SQ" suffix denotes the AEC-Q qualified version. Diodes explicitly states BAV23AQ/CQ/SQ are automotive-compliant per JEDEC standards referenced in AEC-Q, with full qualification testing for temperature cycling, humidity, and mechanical shock per their quality definitions portal.

How does BAV23SQ-13-F differ from BAV23A-13-F?

BAV23SQ-13-F is the automotive-qualified, common-cathode variant; BAV23A-13-F is the commercial-grade, common-anode version. They share identical V_RRM, I_F, and t_RR, but differ in polarity configuration, qualification status, and marking code - making them non-interchangeable without schematic and layout changes.

What is the maximum operating temperature for continuous use?

The junction temperature range is –55°C to +150°C. For continuous operation at full 400 mA forward current, ambient must be limited to ≤+85°C per the power derating curve (Figure 1), assuming standard FR-4 PCB mounting with 1" × 1" copper pad per Diodes Note 5.
