Product details
Overview
BAV23AQ-7-F from Diodes Incorporated is an AEC-Q101 qualified dual high-voltage switching diode in SOT23 package, featuring 250 V repetitive peak reverse voltage, 400 mA forward current per diode, and 50 ns reverse recovery time. It serves as a compact, low-leakage rectifier or signal clamping element in automotive power management and battery protection circuits.
For engineers reviewing the BAV23AQ-7-F datasheet, BAV23AQ-7-F pinout, BAV23AQ-7-F application, or BAV23AQ-7-F equivalent, this device is selected for high-reliability 12 V/24 V automotive subsystems requiring fast switching, thermal stability up to +150°C, and RoHS-compliant lead-free construction.
Technical Context
The BAV23AQ-7-F integrates two independent silicon switching diodes in a single SOT23-3 package with common cathode configuration (Pin 1: Anode 1, Pin 2: Cathode, Pin 3: Anode 2). Its 250 V VRRM and 100 nA IR at 200 V enable robust blocking in transient-prone automotive environments.
With 50 ns tRR at 30 mA and 1.0 V VF at 100 mA, it supports efficient high-frequency rectification and clamping in DC-DC converters and ECU input protection stages, while its 357 °C/W RθJA reflects thermal performance on standard FR-4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 250 V - Withstands repetitive 250 V reverse transients without breakdown, suitable for 24 V automotive supply rail protection. |
| IF | 400 mA - Continuous forward current per diode; supports dual-path 200 mA loads when paralleled per datasheet Note 7. |
| tRR | 50 ns - Fast recovery enables use in >100 kHz switching applications without excessive switching loss. |
| IR | 100 nA @ 200 V, 25°C - Ultra-low leakage preserves battery life in always-on vehicle modules. |
| CT | 5.0 pF @ 0 V - Low junction capacitance minimizes signal distortion in RF detection or high-speed clamping. |
| PD | 350 mW - Power dissipation limit on standard FR-4 board; derates linearly above +25°C ambient. |
Pinout & Package
Package: SOT23-3, surface-mount plastic case (UL 94V-0), 0.008 g weight, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode of Diode 1 | Input node for first diode path; connects to source-side of clamp or rectifier leg. |
| Pin 2 | Common Cathode | Shared output node; ties both diodes' cathodes for dual-anode, single-cathode topology. |
| Pin 3 | Anode of Diode 2 | Input node for second diode path; enables independent routing of two signal/power paths. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive underhood and cabin applications with full PPAP capability and IATF16949 manufacturing. |
| Lead-free & Green compliance | Meets RoHS 3 (2015/863/EU) and halogen/antimony-free requirements (<900 ppm Br+Cl, <1000 ppm Sb). |
| High VRRM/low IR ratio | 250 V blocking with only 100 nA leakage at 25°C ensures long-term reliability in 12–24 V systems. |
| Fast tRR with low CT | 50 ns recovery and 5.0 pF capacitance support clean edge handling in CAN/LIN bus protection and sensor interface clamping. |
Applications

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-7-F | Same package and ratings, but optimized for general industrial use (non-AEC-Q101 certified). | Lacks PPAP documentation and automotive change control; not approved for safety-critical vehicle functions. | Select when AEC-Q101 compliance is unnecessary and cost optimization is prioritized. |
| NSR20F25NXT5G | 250 V VRRM, 200 mA IF, 35 ns tRR, SOD-523 package - smaller footprint, lower current rating. | Better suited for space-constrained portable electronics; insufficient for 400 mA automotive loads. | Choose only for ultra-compact designs where 200 mA per diode suffices and thermal margin allows. |
Compared with BAV23CQ-7-F, the BAV23AQ-7-F adds automotive qualification and traceability; versus NSR20F25NXT5G, it trades size for higher current capacity and automotive readiness-critical for under-hood deployment.

FAQ
What is the pin configuration of BAV23AQ-7-F?
The BAV23AQ-7-F uses a SOT23-3 package with Pin 1 as Anode 1, Pin 2 as Common Cathode, and Pin 3 as Anode 2. This dual-anode, single-cathode arrangement supports independent forward conduction paths sharing one output node, confirmed by Diodes Incorporated's top-view marking diagram and DS42143 Rev. 2 schematic.
Is BAV23AQ-7-F suitable for 24 V commercial vehicle applications?
Yes. Its 250 V VRRM, AEC-Q101 qualification, and operation from –65°C to +150°C meet ISO 16750-2 requirements for commercial truck ECUs. The 100 nA reverse leakage at 200 V ensures minimal standby drain on 24 V batteries during ignition-off states.
How does thermal derating work for BAV23AQ-7-F?
Per Figure 1 in DS42143 Rev. 2, the 350 mW maximum power dissipation linearly derates from +25°C ambient at 3.5 mW/°C. At +100°C ambient, usable power drops to 93.75 mW. This requires careful layout with thermal vias and copper pour when operating near IF limits in high-temp environments.
Can BAV23AQ-7-F replace single-diode packages like 1N4148W in automotive designs?
No. While electrically similar in speed and VF, the BAV23AQ-7-F is a dual-diode device with common cathode topology-not a drop-in replacement for single-diode SOD-123 or SOD-323 packages. Its pinout and dual functionality require circuit-level redesign, not board-level substitution.
