Product details
Overview
BAV99Q-7-F from Diodes Incorporated is a dual high-speed switching diode in SOT23 package, rated for 75 V peak repetitive reverse voltage and 300 mA forward current per element, with 4.0 ns reverse recovery time and 2.0 pF junction capacitance at 0 V - used in ESD protection, signal clamping, and logic-level translation circuits in automotive infotainment and body control modules.
For engineers reviewing the BAV99Q-7-F datasheet, BAV99Q-7-F pinout, BAV99Q-7-F application, or BAV99Q-7-F equivalent, key selection criteria include AEC-Q101 qualification, low trr for high-frequency switching, tight VF matching between elements, and SOT23 thermal performance under 357°C/W RθJA conditions.
Technical Context
The BAV99Q-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). It operates across –55°C to +150°C and supports fast transient response due to its low stored charge and sub-4 ns trr.
Designed for automotive-grade reliability, it features IATF 16949 manufacturing, PPAP capability, and halogen/antimony-free "Green" molding compound compliant with RoHS 3. Its 350 mW power dissipation is derated linearly above +25°C ambient per Figure 1.

IC Role / Device Role / Timing Role: Dual clamping diode providing bidirectional overvoltage suppression on TX/RX lines. Use Value: Prevents latch-up in transceivers using 75 V VRWM rating and maintains <2.0 pF loading to avoid signal edge degradation. | Use Scenario: Level-shifting analog sensor outputs (e.g., thermistor bridges) to 3.3 V microcontroller ADC inputs. IC Role / Device Role / Timing Role: Precision forward-biased clamp limiting input voltage to safe range during fault conditions. Use Value: Matches VF within ±5 mV between elements, ensuring consistent offset correction across dual-sensor channels. |
| USB 2.0 Data Line Protection | Smartphone Camera Module ESD Clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99-7-F | Non-automotive grade; lacks AEC-Q101 qualification and PPAP documentation | Suitable only for commercial-grade consumer electronics; not approved for automotive BOMs | Select when cost sensitivity outweighs automotive compliance requirements |
| NSR0230HT1G | Single diode, 30 V VRWM, 0.45 ns trr, 0.45 pF CT - higher speed but lower voltage rating | Better for 3.3 V logic protection; insufficient for 24 V automotive rail clamping | Choose for ultra-high-speed, low-voltage applications where dual-element integration is not required |
Compared with BAV99-7-F, the BAV99Q-7-F adds automotive qualification without sacrificing speed or capacitance; versus NSR0230HT1G, it trades raw speed for dual-channel integration and 2.5× higher reverse voltage - critical for robustness in 12/24 V systems.

FAQ
What is the pin configuration of BAV99Q-7-F?
BAV99Q-7-F uses a standard SOT23-3 pinout: Pin 1 is Anode 1, Pin 2 is the common cathode, and Pin 3 is Anode 2. This dual-common-cathode arrangement allows independent signal routing through each diode while sharing a single return path - confirmed by Diodes' DS12007 Rev. 29 schematic and top-view marking diagram.
Is BAV99Q-7-F compatible with lead-free reflow processes?
Yes. BAV99Q-7-F features matte tin finish annealed over alloy 42 leadframe and is fully RoHS 3 compliant. It meets MIL-STD-202 Method 208 solderability requirements and supports standard Pb-free reflow profiles up to 260°C peak temperature, with moisture sensitivity level 1 per J-STD-020.
How does BAV99Q-7-F differ from BAV99-7-F beyond AEC-Q101 qualification?
Both share identical electrical specs and SOT23 packaging, but BAV99Q-7-F is manufactured in IATF 16949-certified facilities, includes PPAP documentation, and uses halogen/antimony-free "Green" molding compound (Br+Cl <1500 ppm). BAV99-7-F may use non-Green compound in pre-2009 date codes and lacks automotive change-control tracking.
Can BAV99Q-7-F be used for bidirectional ESD protection on differential pairs?
Yes - its dual common-cathode structure supports back-to-back connection (Anode1–Cathode–Anode2) across differential lines, clamping positive and negative transients to VCC and GND. With 2.0 pF CT and matched VF, it preserves signal symmetry and meets IEC 61000-4-2 Level 4 (±8 kV contact) when paired with appropriate series impedance.
