Product details

Overview

BAV23A-7 from Diodes Incorporated is a surface-mount high-voltage dual switching diode in SOT23 package, featuring 250 V repetitive peak reverse voltage (V_RRM), 50 ns reverse recovery time (t_RR), and 400 mA forward current (I_F). It serves as a fast-switching, low-leakage voltage-clamping or signal routing element in DC-DC converter flyback snubbers, battery protection circuits, and portable power management systems.

For engineers reviewing the BAV23A-7 datasheet, BAV23A-7 pinout, BAV23A-7 application, or BAV23A-7 equivalent, key selection criteria include its 200 V working peak reverse voltage, 100 nA leakage at 200 V/25°C, dual-diode configuration with common-cathode topology, and JEDEC-qualified reliability for industrial and automotive-adjacent designs.

Technical Context

The BAV23A-7 integrates two independent silicon switching diodes in a single SOT23 package with common-cathode connection. Its fast recovery (t_RR ≤ 50 ns) and low capacitance (C_T ≤ 5.0 pF at 0 V) support high-frequency operation up to several MHz in snubber networks and signal demultiplexing paths.

Thermal performance is defined by 357 °C/W junction-to-ambient resistance on standard FR-4 PCB, enabling 350 mW total power dissipation at 25°C ambient. The device operates across –55°C to +150°C, with leakage rising to 100 µA at 150°C - critical for thermal design in compact, unventilated enclosures.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	250 V - supports input transient suppression in 12–48 V industrial bus systems without breakdown
t_RR	50 ns - enables clean switching in PWM frequencies up to 2 MHz without tail current losses
I_F	400 mA - sufficient for dual-diode parallel load sharing in low-power DC-DC feedback paths
I_R @ 200 V, 25°C	100 nA - ensures minimal standby current drain in battery-backed real-time clock circuits
C_T @ 0 V, 1 MHz	5.0 pF - maintains signal integrity in RF detector or high-speed logic clamping applications
P_D	350 mW - defines maximum continuous dissipation on standard 1" × 1" FR-4 board with 2 oz copper
T_J Range	–55°C to +150°C - qualifies for under-hood or industrial control cabinet deployment

Pinout & Package

High reverse breakdown voltage	250 V V_RRM provides 25% margin over 200 V DC bus rails in telecom and industrial power supplies
Low leakage current	100 nA I_R at 200 V/25°C minimizes quiescent current in always-on battery monitoring circuits
JEDEC-qualified reliability	Qualified per AEC-Q standards - suitable for extended-life embedded systems where field failure risk must be minimized
Lead-free & green construction	Matte tin-plated terminals, halogen/antimony-free mold compound - meets RoHS 3 and automotive environmental compliance

Applications

DC-DC Converter Snubber

Battery Protection Circuit

Use Scenario: Clamps voltage spikes across MOSFETs in flyback or boost converter primary switches.

IC Role / Device Role / Timing Role: Dual-diode clamp with common cathode tied to controller ground; each anode connected to separate switching node.

Use Value: 50 ns t_RR and 250 V V_RRM suppress transients faster than standard rectifiers, reducing EMI and MOSFET stress.

Use Scenario: Prevents reverse current flow from main battery to backup cell or auxiliary rail during fault conditions.

IC Role / Device Role / Timing Role: Dual-anode, common-cathode diode pair isolates two battery domains while sharing ground reference.

Use Value: 100 nA leakage at 25°C preserves shelf life; 400 mA I_F handles peak load surges during hot-swap events.

Portable Device Power Routing

Industrial Sensor Signal Clamping

Use Scenario: Selects between USB and battery power sources in handheld medical or test equipment.

IC Role / Device Role / Timing Role: Each diode anode accepts one input source; common cathode feeds system PMIC input rail.

Use Value: Low forward voltage (≤1.25 V @ 200 mA) minimizes dropout; SOT23 footprint saves space in tight PCB layouts.

Use Scenario: Limits analog sensor output voltage to ADC input range (e.g., ±10 V) in PLC I/O modules.

IC Role / Device Role / Timing Role: Configured as back-to-back clamp with external resistors; one diode conducts positive overvoltage, the other negative.

Use Value: 5.0 pF C_T avoids loading high-impedance sensor outputs; 150°C T_J rating supports operation near motor drives.

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
BAV23C-7-F	Same package and ratings, but common-anode configuration instead of common-cathode	Requires inverted PCB layout and reversed biasing in clamping or OR-ing circuits	Select when cathode-referenced grounding is impractical or when sourcing from positive rails dominates system architecture
MMBD231C-7-F	Lower V_RRM (100 V), higher leakage (500 nA), same SOT23 package and dual-diode topology	Suitable only for ≤48 V systems; not recommended for 200 V bus protection or flyback snubbing	Choose for cost-sensitive, low-voltage portable designs where 250 V margin is unnecessary and leakage tolerance is relaxed

Compared with BAV23C-7-F and MMBD231C-7-F, the BAV23A-7 uniquely delivers 250 V standoff with common-cathode polarity in a qualified industrial-grade package - making it optimal for high-reliability, high-voltage dual-path clamping where ground-referenced cathodes simplify layout and reduce noise coupling.

FAQ

What is the pin configuration of BAV23A-7?

BAV23A-7 uses a standard SOT23 package with Pin 1 = Anode 1, Pin 2 = Common Cathode, Pin 3 = Anode 2. This common-cathode arrangement allows both diodes to share a grounded or reference-rail return path, simplifying PCB routing in dual-input power OR-ing and bidirectional clamping applications.

Is BAV23A-7 suitable for automotive applications?

The BAV23A-7 is not automotive-qualified; however, its AEC-Q–referenced qualification (per Diodes' internal reliability testing) supports use in industrial and commercial applications with extended temperature and lifetime requirements. For automotive systems, the pin-compatible BAV23AQ-7-F variant - explicitly qualified to AEC-Q101 - must be selected.

How does thermal derating affect BAV23A-7's power handling?

BAV23A-7's 350 mW maximum power dissipation applies only at 25°C ambient. Above that, power must be linearly reduced per the published derating curve: at 100°C ambient, usable power drops to ~175 mW. This requires careful thermal layout - including adequate copper pour and via stitching - in enclosed or high-temperature environments.

Can BAV23A-7 replace single-diode packages like 1N4148 in dual-path designs?

Yes - BAV23A-7 replaces two 1N4148 diodes in a single SOT23 footprint, offering identical fast switching (50 ns vs. 4 ns for 1N4148) but with higher V_RRM (250 V vs. 100 V) and lower leakage. However, its dual-diode interconnection (common cathode) mandates circuit-level redesign versus discrete placement, especially in non-common-reference topologies.
