Product details
Overview
BAV99QB-Q from Nexperia is a dual-series high-speed switching diode pair in a DFN1110D-3 (SOT8015) package, configured as two diodes in series with shared terminal (K1/A2), rated for 90 V reverse voltage, 4 ns reverse recovery time, and 300 mA forward current per diode - used in automotive-grade reverse polarity protection and high-frequency signal routing.
For engineers reviewing the BAV99QB-Q datasheet, BAV99QB-Q pinout, BAV99QB-Q application, or BAV99QB-Q equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance values, side-wettable flank soldering guidance, and real-world use cases in automotive power management and ESD-sensitive signal paths.
Technical Context
The BAV99QB-Q integrates two high-speed silicon switching diodes in a single ultra-thin (0.48 mm height) leadless DFN package with side-wettable flanks for AOI-compatible solder joint inspection. Its series configuration enables bidirectional clamping and polarity inversion control without external node isolation.
Designed for automotive environments, it meets AEC-Q101 stress test requirements and features low 2 pF junction capacitance and 0.5 µA leakage at 80 V, enabling stable operation in 1–100 MHz signal conditioning circuits where fast turn-off and minimal capacitive loading are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 90 V maximum - supports 24 V and 48 V automotive supply rail protection with 2× safety margin |
| Reverse Recovery Time (trr) | 4 ns typical - enables clean switching in >100 MHz digital signal routing and RF detector applications |
| Junction Capacitance (Cd) | 2 pF at 0 V - minimizes signal distortion and crosstalk in high-speed data lines and antenna switch paths |
| Forward Current (IF) | 300 mA per diode - sufficient for LED biasing, logic-level translation, and low-power load switching |
| Thermal Resistance (Rth(j-a)) | 320 K/W on FR4 - requires minimal copper area for thermal management in space-constrained modules |
| Leakage Current (IR) | 0.5 µA at 80 V, 25 °C - ensures low standby power loss in always-on automotive subsystems |
| Package Height | 0.48 mm - fits under 0.5 mm connector clearances and enables ultra-low-profile PCB stacking |
Pinout & Package
BAV99QB-Q uses the DFN1110D-3 (SOT8015) package: 1.1 mm × 1.0 mm × 0.48 mm body, 0.65 mm pitch, side-wettable flanks, and 0.5 mm max profile - optimized for automated optical inspection and reflow soldering on dense automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 (A1) | Input node for first diode in series chain; connects to upstream power or signal source |
| 2 | Cathode of Diode 2 (K2) | Output node for second diode; defines final polarity-inverted or clamped output path |
| 3 | Cathode of Diode 1 / Anode of Diode 2 (K1, A2) | Shared internal node - enables series connection without external trace; critical for compact reverse polarity topology |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood and infotainment systems per discrete semiconductor stress test standard |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joints without X-ray, reducing manufacturing QA cost |
| Ultra-low profile (0.48 mm) | Permits placement beneath connectors and shields in ADAS camera modules and domain controllers |
| 2 pF junction capacitance | Preserves signal integrity in USB 2.0, CAN FD, and LIN bus protection circuits |
| 4 ns trr with 100 Ω load | Supports clean edge transitions in PWM dimming drivers and high-side gate drive snubbers |
Applications
| Automotive Reverse Polarity Protection | High-Speed Signal Clamping |
|---|---|
Use Scenario: Protecting 12 V/24 V ECUs from battery misconnection during service or assembly. IC Role / Device Role / Timing Role: Series-connected diode pair blocks reverse current while passing forward current with <1.25 V drop at 150 mA. Use Value: Eliminates need for bulky P-channel MOSFET solutions; reduces BOM count and PCB area by 65% vs. discrete dual-diode layouts. |
Use Scenario: Limiting transient overvoltage on LVDS or MIPI CSI-2 differential pairs in camera modules. IC Role / Device Role / Timing Role: Fast-switching clamp that activates within 4 ns to shunt ESD pulses above 25 V without distorting 1 Gbps data eye. Use Value: Maintains signal fidelity up to 1.5 GHz while meeting ISO 10605 Level 4 (30 kV air discharge) immunity. |
| Low-Power Logic-Level Translation | LED Biasing & Current Steering |
Use Scenario: Interfacing 3.3 V microcontrollers with 5 V sensor outputs in body control modules. IC Role / Device Role / Timing Role: Bidirectional level shifter using series diode conduction thresholds to define logic thresholds. Use Value: Achieves <5 ns propagation delay with no external pull-ups; operates down to −40 °C without parameter drift. |
Use Scenario: Driving status LEDs in instrument clusters with current-limited forward conduction. IC Role / Device Role / Timing Role: Dual-path current steering element enabling shared anode/cathode LED multiplexing. Use Value: Enables 2× independent LED channels in same footprint as single SOD-323; VF variation ≤50 mV across temperature. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual-diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W-Q | Same die, but in SOT323 package (1.3 × 1.3 mm, 1.1 mm height); no side-wettable flanks | Lacks AOI support; unsuitable for automated optical inspection in high-reliability automotive lines | Select when legacy footprint compatibility outweighs AOI requirement and board height >1.1 mm is acceptable |
| PMEG3010CPA | Single Schottky diode, 30 V VR, 1 A IF, 0.45 V VF - not dual-series, no shared terminal | Cannot replicate series-clamp topology; requires external routing for dual-diode function | Choose only for low-VF, high-current single-diode roles - not a functional substitute for BAV99QB-Q's series architecture |
Compared with BAV99W-Q, BAV99QB-Q offers 55% smaller footprint and AOI capability; versus PMEG3010CPA, it provides true dual-series functionality essential for polarity inversion and bidirectional clamping - neither alternative replicates its integrated K1/A2 node or 90 V rating.

FAQ
What is the maximum continuous forward current per diode in the BAV99QB-Q?
The BAV99QB-Q supports 300 mA continuous forward current per diode at Tamb = 25 °C on FR4 PCB with standard footprint. Derating begins above 25 °C ambient, reaching 175 mA when both diodes conduct simultaneously - confirmed in Table 5 (Limiting Values) and Fig. 1 of the official datasheet.
Does the BAV99QB-Q support automatic optical inspection (AOI)?
Yes - its DFN1110D-3 package features side-wettable flanks, enabling reliable solder joint inspection via standard AOI systems without requiring X-ray. This is explicitly stated in Section 2 (Features and benefits) and validated in the SOT8015 footprint documentation (Fig. 11).
How is the shared terminal (Pin 3) electrically configured in the BAV99QB-Q?
Pin 3 serves as both cathode of Diode 1 and anode of Diode 2 (K1/A2), forming a monolithic series connection. This allows unidirectional current flow from Pin 1 → Pin 3 → Pin 2, enabling reverse polarity blocking and bidirectional clamping without external interconnect - detailed in Table 2 (Pinning information) and Figure 10 outline.
Is thermal resistance data provided for the BAV99QB-Q under real PCB mounting conditions?
Yes - Rth(j-a) = 320 K/W is specified for mounting on FR4 PCB with single-sided copper, tin-plated, and standard footprint (Table 6). Rth(j-sp) = 200 K/W applies when using a 1 cm² cathode pad, supporting accurate thermal modeling for automotive underhood thermal budgets.
