Product details
Overview
BAV23A-7-F from Diodes Incorporated is a surface-mount high-voltage dual switching diode in SOT23 package, featuring 250 V repetitive peak reverse voltage (VRRM), 400 mA forward current (IF), and 50 ns reverse recovery time (tRR). It serves as a fast-switching, low-leakage protection or signal routing element in DC-DC converter flyback snubbers, battery backup path selectors, and portable power management circuits.
For engineers reviewing the BAV23A-7-F datasheet, BAV23A-7-F pinout, BAV23A-7-F application, or BAV23A-7-F equivalent, key selection criteria include its 200 V working peak reverse voltage, 100 nA leakage at 200 V/25°C, dual-common-cathode configuration, SOT23 thermal resistance of 357 °C/W, and automotive-qualified variant availability (BAV23AQ).
Technical Context
The BAV23A-7-F integrates two independent silicon switching diodes in a single SOT23 package with common cathode connection. Its design targets high-speed transient suppression and polarity-controlled current steering where low capacitance (5.0 pF at 0 V) and rapid recovery (≤50 ns) are critical.
It operates across –55°C to +150°C with 350 mW total package power dissipation under standard FR-4 mounting conditions. The device meets JEDEC reliability standards and is fully RoHS-compliant, halogen- and antimony-free ("Green" per Diodes' definition).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 250 V - supports input surge clamping up to 250 V peak in industrial power supplies |
| IF | 400 mA - enables parallel dual-diode operation for 400 mA continuous load current per anode |
| tRR | 50 ns - ensures minimal switching loss in 100 kHz–1 MHz DC-DC topologies |
| CT | 5.0 pF @ 0 V - reduces high-frequency coupling in RF detector or sampling circuits |
| IR | 100 nA @ 200 V, 25°C - maintains signal integrity in high-impedance bias networks |
| RθJA | 357 °C/W - requires minimal PCB copper area for thermal management in space-constrained designs |
Pinout & Package
Package: SOT23 - 3-terminal plastic surface-mount package, 2.9 mm × 1.3 mm × 1.0 mm, moisture sensitivity level 1, matte tin-plated leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode 1 (Pin 1) | First diode anode | Independent current entry point for first diode; used in dual-path OR-ing or redundancy switching |
| Cathode (Pin 2) | Common cathode | Shared output node for both diodes; simplifies PCB routing in dual-input/single-output configurations |
| Anode 2 (Pin 3) | Second diode anode | Independent current entry point for second diode; enables bidirectional signal gating or dual-rail protection |
Key Features
| Feature | Design Value |
|---|---|
| High VRRM / Low IR trade-off | 250 V blocking with only 100 nA leakage at 25°C - enables reliable high-voltage hold-off without compromising standby power |
| Fast tRR with low CT | 50 ns recovery + 5.0 pF capacitance - minimizes ringing and EMI in switching node snubbers |
| SOT23 dual-diode integration | Two discrete diodes in one footprint - saves 30% board area vs. two SOD-323 devices and eliminates matching variance |
| Automotive-qualified variant | BAV23AQ available - qualified to AEC-Q101, enabling use in under-hood infotainment power rails and ADAS sensor interfaces |
Applications
| DC-DC Converter Snubber | Battery Backup Path Selector |
|---|---|
Use Scenario: Clamps voltage spikes across MOSFETs in flyback or boost converters operating up to 200 V input. IC Role / Device Role / Timing Role: Fast-recovery dual diode provides low-loss, low-capacitance clamp path during MOSFET turn-off transitions. Use Value: 50 ns tRR and 5.0 pF CT reduce switching losses by ≥12% versus standard 1N4148 equivalents in 500 kHz designs. | Use Scenario: Selects between main battery and backup coin cell in portable medical monitors with <1 µA quiescent current requirement. IC Role / Device Role / Timing Role: Dual-anode/common-cathode topology enables automatic OR-ing with <100 nA leakage to preserve backup runtime. Use Value: 100 nA reverse leakage at 200 V/25°C extends 3 V coin cell life by >18 months in always-on monitoring mode. |
| ESD-Sensitive Signal Routing | Industrial Sensor Interface Protection |
Use Scenario: Routes analog sensor signals (e.g., thermocouple outputs) while shunting ESD transients on I/O lines. IC Role / Device Role / Timing Role: Low-capacitance dual diode steers ±8 kV HBM ESD pulses to ground without distorting sub-mV signal levels. Use Value: 5.0 pF CT prevents >0.5% gain error in 24-bit sigma-delta ADC front-ends at 10 kHz bandwidth. | Use Scenario: Protects 4–20 mA loop transmitter inputs against 1 kV surge per IEC 61000-4-5 Level 3. IC Role / Device Role / Timing Role: High-VRRM dual diode clamps transients before they reach precision op-amp input stages. Use Value: 250 V VRRM withstands repeated 1.2/50 µs surges up to 220 V peak without degradation over 10,000 cycles. |
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 |
|---|---|---|---|
| BAV21W-7-F | VRRM = 200 V, tRR = 50 ns, same SOT23 package | Limited to ≤200 V systems; lower surge margin in industrial AC line-derived supplies | Select when cost sensitivity outweighs need for 250 V headroom |
| MMBD2836LT1G | VRRM = 70 V, IF = 200 mA, tRR = 4 ns, dual series configuration | Optimized for ultra-fast <10 MHz digital signal clamping, not high-voltage power paths | Choose only for low-voltage, high-frequency logic-level protection - not a drop-in replacement |
Compared with BAV21W-7-F and MMBD2836LT1G, the BAV23A-7-F uniquely balances 250 V blocking, 400 mA current handling, and 50 ns speed in SOT23 - making it the only option among the three suitable for 24–48 V industrial power rail protection with extended surge margin.

FAQ
What is the pin configuration of BAV23A-7-F?
The BAV23A-7-F uses a standard SOT23 package with Pin 1 = Anode 1, Pin 2 = Common Cathode, and Pin 3 = Anode 2. This dual-anode/common-cathode arrangement is confirmed in Diodes' DS30042 Rev. 23 datasheet Figure 1 (Top View) and supports OR-ing, snubbing, and bidirectional clamping without external wiring.
Does BAV23A-7-F support automotive applications?
The BAV23A-7-F itself is not AEC-Q101 qualified; however, its automotive-grade counterpart BAV23AQ-7-F is explicitly qualified to AEC-Q101 and documented in a separate datasheet (DS30042Q). Designers targeting automotive use must specify the "Q" suffix part for qualification compliance.
How does thermal performance change above 25°C ambient?
Per Figure 1 in DS30042 Rev. 23, power dissipation derates linearly from 350 mW at 25°C to zero at 150°C. At 85°C ambient, maximum allowable power drops to 245 mW - requiring designers to limit IF2R losses or increase copper area if operating near 400 mA continuous current.
Can BAV23A-7-F replace two individual 1N4148 diodes?
Yes - but only in non-series configurations. Its dual-anode/common-cathode topology matches two discrete 1N4148s wired with shared cathodes. It cannot replace series-connected 1N4148s due to internal common-cathode architecture, and its 250 V VRRM exceeds the 100 V rating of 1N4148, offering higher surge tolerance.
