Product details

Overview

BAV23S-7-F from Diodes Incorporated is a surface-mount dual high-voltage 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 and signal routing element in DC-DC converter flyback snubbers, battery backup path selectors, and portable device power management circuits.

For engineers reviewing the BAV23S-7-F datasheet, BAV23S-7-F pinout, BAV23S-7-F application, or BAV23S-7-F equivalent, key selection criteria include its dual-common-cathode configuration, low 100 nA reverse leakage at 200 V/25°C, 350 mW power dissipation, JEDEC-qualified reliability, and RoHS-compliant lead-free plating - all critical for space-constrained, high-reliability portable and industrial power designs.

Technical Context

The BAV23S-7-F integrates two independent silicon switching diodes in a single SOT23-3 package with common cathode connection (Pin 2 = Cathode, Pins 1 & 3 = Anodes). Its fast recovery (t_RR ≤ 50 ns) enables efficient operation in 100–500 kHz switching power supplies and transient suppression circuits.

Designed for high-voltage tolerance, it sustains 250 V V_RRM and exhibits low junction capacitance (C_T ≤ 5.0 pF at 0 V), supporting minimal signal distortion in RF detector and clamp applications while maintaining thermal stability across –55°C to +150°C operating range.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	250 V - Withstands repetitive reverse transients up to 250 V without breakdown, suitable for 24–48 V system rail clamping
I_F	400 mA - Continuous forward current per diode; supports dual-path 200 mA load sharing when paralleled
t_RR	50 ns - Fast recovery enables use in <500 kHz SMPS output rectification and snubber networks
I_R @ 200 V	100 nA @ 25°C - Ultra-low leakage preserves battery life in always-on portable backup paths
C_T	5.0 pF @ 0 V - Low junction capacitance minimizes RF signal loading in detector/clamp stages
P_D	350 mW - Power limit at T_A = 25°C; derates linearly to zero at 150°C ambient
R_θJA	357 °C/W - Thermal resistance defines junction-to-ambient rise under standard FR-4 PCB layout

Pinout & Package

Package: SOT23-3, surface-mount plastic package with matte tin-plated Alloy 42 leadframe; moisture sensitivity level 1 (J-STD-020); weight ≈ 0.008 g.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1	Anode of Diode 1	Input node for first diode path; connects to source in high-side OR-ing or clamp
Pin 2	Common Cathode	Shared output node; ties both diodes to ground or return rail in dual-path design
Pin 3	Anode of Diode 2	Input node for second diode path; enables redundant input selection or dual-rail sensing

Key Features

Feature	Design Value
Dual common-cathode configuration	Enables compact OR-ing of two independent power sources (e.g., main + battery) with single-point return
250 V V_RRM rating	Supports direct interface with 200 V DC bus rails and flyback transformer secondary spikes
50 ns t_RR	Reduces switching loss and EMI in high-frequency DC-DC converters versus general-purpose diodes
100 nA I_R @ 200 V / 25°C	Minimizes standby current drain in battery-backed real-time clock and memory retention circuits
JEDEC-qualified reliability	Validated per AEC-Q stress tests for extended lifetime in automotive and industrial control modules

Applications

Battery Backup Path Selection

DC-DC Converter Snubber

Use Scenario: Dual-input power system where main supply and coin-cell battery feed same rail via automatic switchover.

IC Role / Device Role / Timing Role: Dual diode provides passive OR-ing with minimal forward drop and no control logic required.

Use Value: Eliminates need for dedicated power-path IC; 1.0 V V_F @ 100 mA ensures <2% voltage loss during battery fallback.

Use Scenario: RCD snubber network across flyback transformer primary to suppress voltage spikes during MOSFET turn-off.

IC Role / Device Role / Timing Role: Fast-recovery diode clamps transient energy into capacitor with minimal ringback.

Use Value: 50 ns t_RR prevents reverse conduction during critical dead-time, improving snubber efficiency by >15% vs. 1N4148.

Portable Device Power Rail Clamping

Signal-Level Voltage Clamp

Use Scenario: Protecting 3.3 V microcontroller I/O pins from accidental 12–24 V misconnection in handheld test equipment.

IC Role / Device Role / Timing Role: Reverse-biased diode limits positive overvoltage to V_CC + 0.7 V using internal rail as reference.

Use Value: 250 V V_RRM provides large safety margin; 100 nA leakage avoids measurable bias current error.

Use Scenario: AC-coupled audio or sensor signal conditioning where peak voltage must be limited to ±5 V.

IC Role / Device Role / Timing Role: Dual diode forms bidirectional clamp to rails using external resistors and shared cathode.

Use Value: 5.0 pF C_T ensures <0.1 dB insertion loss at 10 MHz; matched dual structure simplifies layout symmetry.

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
BAV23C-7-F	Same package and ratings, but common-anode configuration (Pins 1 & 3 = Cathodes, Pin 2 = Anode)	Suitable for dual-sink (e.g., LED driver cathode switching) rather than dual-source OR-ing	Select BAV23C-7-F only when circuit requires sinking current from two loads to one node
MMBD2836LT1G	Lower V_RRM (100 V), higher t_RR (75 ns), same SOT23-3 common-cathode pinout	Limited to ≤48 V systems; less effective in high-dV/dt snubbers	Choose only if cost sensitivity outweighs 150 V headroom and 25 ns speed penalty

Compared with BAV23C-7-F and MMBD2836LT1G, the BAV23S-7-F uniquely delivers 250 V blocking with 50 ns recovery in common-cathode topology - making it irreplaceable for high-voltage dual-source OR-ing and fast transient clamping where both voltage margin and timing precision are non-negotiable.

FAQ

What is the pin configuration of BAV23S-7-F?

BAV23S-7-F uses a common-cathode SOT23-3 arrangement: Pin 1 = Anode 1, Pin 2 = Common Cathode, Pin 3 = Anode 2. This allows independent anode inputs feeding a shared return path - ideal for dual-power-source OR-ing and bidirectional clamping circuits.

Is BAV23S-7-F suitable for automotive applications?

BAV23S-7-F itself is not AEC-Q200 qualified; however, the automotive-grade variant BAV23SQ-7-F is available and certified to AEC-Q200 standards. For non-automotive industrial or consumer designs, BAV23S-7-F meets JEDEC reliability requirements and operates from –55°C to +150°C.

How does BAV23S-7-F differ from BAV23A-7-F?

BAV23A-7-F has isolated diodes (no shared terminal), while BAV23S-7-F features common-cathode connection and BAV23C-7-F uses common-anode. The "S" suffix explicitly denotes shared cathode - critical for circuit topologies requiring dual anodes tied to one output node.

What is the maximum continuous forward current per diode?

The datasheet specifies 400 mA I_F for the BAV23S-7-F when both diodes are operated in parallel. When used individually, each diode supports 400 mA continuously; when loaded in series, the rating drops to 200 mA per diode due to thermal coupling and voltage sharing constraints.
