Product details
Overview
BAV23AQ-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 clamping and signal routing device in DC-DC converter flyback snubbers and ESD-protected sensor interfaces.
For engineers reviewing the BAV23AQ-13-F datasheet, BAV23AQ-13-F pinout, BAV23AQ-13-F application, or BAV23AQ-13-F equivalent, key selection criteria include reverse breakdown margin at elevated temperature, low leakage (<100 nA @ 200 V, 25°C), fast tRR for high-frequency switching, and dual-diode integration in space-constrained automotive modules.
Technical Context
This dual discrete diode integrates two independent silicon PN junctions 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 rating enables use in 24 V and 48 V automotive power rails where transient suppression exceeds ISO 7637-2 Pulse 1/2b requirements.
The 50 ns tRR and 1.25 V VF max @ 200 mA support operation up to 1 MHz in synchronous rectifier auxiliary paths and bidirectional signal clamping circuits. Thermal resistance of 357 °C/W (RθJA) on FR-4 mandates derating above 70°C ambient per Figure 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 250 V - Withstands repetitive transients up to 250 V reverse bias without avalanche conduction |
| IFM | 400 mA - Maximum continuous forward current per diode at 25°C ambient |
| tRR | 50 ns - Enables reliable commutation in 1 MHz switching applications |
| IR @ 200 V, 25°C | ≤100 nA - Ensures minimal leakage in high-impedance bias networks |
| VF @ 200 mA | ≤1.25 V - Limits forward power loss to ≤250 mW per diode at rated current |
| CT @ 0 V, 1 MHz | ≤5.0 pF - Minimizes capacitive loading on high-speed digital or RF signal lines |
| Pd | 350 mW - Total package power dissipation limit on standard FR-4 PCB |

Applications
| Automotive Body Control Module (BCM) | Industrial PLC Input Protection |
|---|---|
Use Scenario: Clamping inductive kickback from door lock actuators and mirror motors. IC Role / Device Role / Timing Role: Dual diode provides independent flyback paths for two 12 V solenoid drivers sharing common ground. Use Value: Prevents >100 V transients from damaging MCU GPIOs and driver ICs while occupying minimal PCB area. | Use Scenario: Protecting 24 V digital input channels against field-wiring reversals and surge events. IC Role / Device Role / Timing Role: Each diode routes reverse polarity or surge current to system ground before TVS activation. Use Value: Adds pre-TVС current limiting with <100 nA leakage, preserving input threshold accuracy over temperature. |
| Automotive Camera Power Sequencing | USB-C Port ESD Clamp |
Use Scenario: Controlling power-up sequence between image sensor core and I/O supply domains. IC Role / Device Role / Timing Role: Dual diode steers enable signals with controlled forward drop and isolation during state transitions. Use Value: Eliminates cross-conduction risk between 1.2 V and 2.8 V rails while supporting AEC-Q100 Grade 2 temperature range. | Use Scenario: Low-capacitance clamping on USB-C CC and SBU lines prior to controller IC. IC Role / Device Role / Timing Role: Fast-switching diode shunts ESD pulses (IEC 61000-4-2) to ground before reaching PHY pins. Use Value: 5.0 pF CT ensures <0.1 dB insertion loss at 10 MHz; 50 ns tRR avoids signal distortion on 5 Gbps lanes. |

FAQ
What is the pin configuration of BAV23AQ-13-F?
BAV23AQ-13-F uses a SOT23-3 package with Pin 1 as Anode 1, Pin 2 as Common Cathode, and Pin 3 as Anode 2. This common-cathode dual-diode arrangement allows independent forward conduction paths sharing one return terminal, verified in Diodes Incorporated's DS42143 Rev. 2 schematic diagram and top-view marking layout.
Is BAV23AQ-13-F suitable for 48 V automotive applications?
Yes. With 250 V VRRM and AEC-Q101 qualification, BAV23AQ-13-F supports 48 V battery systems including load dump protection (ISO 7637-2 Pulse 5a), where it withstands transients up to 120 V for 400 ms. Derating curves in DS42143 confirm stable operation up to +125°C junction temperature in under-hood environments.
How does BAV23AQ-13-F differ from BAV23CQ-13-F?
BAV23AQ-13-F and BAV23CQ-13-F share identical electrical specifications, thermal performance, package dimensions, and AEC-Q101 qualification. The only distinction is internal product family coding: AQ uses KT7 marking, CQ uses KT6. Both are manufactured in the same IATF16949 facility and meet identical PPAP documentation requirements.
What is the maximum operating temperature for continuous use?
The BAV23AQ-13-F has an operating temperature range of –65°C to +150°C. For continuous operation at full 400 mA forward current, ambient temperature must not exceed +70°C per the power derating curve (Figure 1 in DS42143), where PD drops linearly to zero at +150°C ambient on standard FR-4 PCB.
