Product details
Overview
BAV23CQ-13-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, automotive-grade protection and signal routing device in DC-DC converter flyback snubbers and battery isolation circuits.
For engineers reviewing the BAV23CQ-13-F datasheet, BAV23CQ-13-F pinout, BAV23CQ-13-F application, or BAV23CQ-13-F equivalent, key selection criteria include reverse breakdown voltage (250 V), low leakage (100 nA at 200 V/25°C), fast tRR (50 ns), thermal resistance (357 °C/W), and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This dual common-cathode diode integrates two independent silicon junctions in one SOT23 package, enabling parallel or series-connected configurations. Its 250 V VRRM rating supports high-side switching in 24 V and 48 V automotive power rails, while the 50 ns tRR ensures minimal switching loss in PWM-controlled flyback and boost converters.
The device operates across –65°C to +150°C and maintains <100 nA IR at 200 V and 25°C, critical for low-power wake-up circuitry. Its 350 mW power dissipation and 357 °C/W RθJA are validated on standard FR-4 PCB with 1" × 1", 2 oz copper pads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 250 V - Withstands transient spikes up to 250 V in automotive load-dump conditions without breakdown. |
| IFM (per diode) | 400 mA - Supports continuous current in low-power auxiliary rails and sensor bias networks. |
| tRR | 50 ns - Enables efficient operation at switching frequencies up to ~2 MHz in DC-DC controllers. |
| IR @ 200 V, 25°C | 100 nA - Ensures negligible standby current in always-on vehicle modules (e.g., CAN transceiver keep-alive). |
| RθJA | 357 °C/W - Requires minimal PCB copper area for thermal management in space-constrained ECUs. |
| CT @ 0 V, 1 MHz | 5.0 pF - Minimizes capacitive loading in high-speed signal clamping and ESD protection paths. |
Pinout & Package
Package: SOT23 - Surface-mount plastic case (UL 94V-0), 0.008 g weight, moisture sensitivity level 1, lead-free matte tin plating over Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Input terminal for first diode; connects to switched node in clamp or OR-ing configuration. |
| Pin 2 | Cathode (common) | Shared cathode node; ties both diodes to reference rail (e.g., VCC or GND) in common-cathode topology. |
| Pin 3 | Anode 2 | Input terminal for second diode; enables dual-path routing (e.g., redundant power inputs or dual-sensor protection). |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood applications including engine control, body electronics, and ADAS sensors. |
| Common-cathode dual configuration | Reduces component count and board area vs. discrete diodes in OR-ing, polarity protection, and snubber circuits. |
| Low IR (100 nA @ 200 V, 25°C) | Preserves battery life in always-on modules such as telematics and remote keyless entry receivers. |
| Fast tRR = 50 ns | Minimizes reverse conduction loss during hard-switching transitions in buck-boost and flyback topologies. |
Applications
| Automotive Body Control Module (BCM) | Industrial PLC Input Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-voltage dual diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV23S-7-F | Same die, SOT23-3L package, but not AEC-Q101 qualified; 100 µA IR max at 200 V/25°C (vs. 100 nA for BAV23CQ). | Restricted to non-automotive industrial or consumer use; unsuitable for PPAP or IATF16949 production environments. | Select only when AEC-Q101 and ultra-low leakage are not required. |
| MMBD2836LT1G | Common-anode dual diode; 100 V VRRM; 200 mA IFM; 4 ns tRR; no AEC-Q101 certification. | Optimized for low-voltage, high-speed digital logic clamping-not for 24/48 V automotive power rails. | Choose only for sub-12 V logic-level signal steering where speed outweighs voltage rating. |
Compared with BAV23S-7-F and MMBD2836LT1G, BAV23CQ-13-F uniquely combines AEC-Q101 qualification, 250 V blocking, 100 nA leakage, and common-cathode topology-making it the sole fit for automotive power-rail protection where reliability, voltage margin, and low standby current are jointly mandatory.

FAQ
What is the pin configuration of BAV23CQ-13-F?
BAV23CQ-13-F uses a standard SOT23-3L package with Pin 1 = Anode 1, Pin 2 = Common Cathode, Pin 3 = Anode 2. This common-cathode arrangement allows simultaneous connection of both diodes to a single reference rail, simplifying PCB layout in dual-path protection schemes.
Is BAV23CQ-13-F suitable for 48 V automotive systems?
Yes - its 250 V VRRM rating provides 5× safety margin above nominal 48 V system peaks, and its AEC-Q101 qualification covers temperature cycling, humidity testing, and mechanical shock requirements defined for under-hood deployment in 48 V mild-hybrid architectures.
How does BAV23CQ-13-F differ from BAV23AQ-13-F?
Both share identical electrical specs and package, but BAV23AQ-13-F carries additional PPAP documentation and change-control tracking per customer-specific automotive program requirements, whereas BAV23CQ-13-F meets full AEC-Q101 and IATF16949 standards without program-specific PPAP deliverables.
Can BAV23CQ-13-F replace single-diode SOD-123 devices in existing designs?
Yes, with layout adaptation: its common-cathode dual structure replaces two SOD-123 diodes, reducing footprint by ~40%. Designers must verify that shared cathode routing doesn't introduce ground-loop noise and that combined thermal load remains within 350 mW total package limit.
