Product details
Overview
BAV99QAZ from Nexperia is a dual-series high-speed switching diode pair in a DFN1010D-3 (SOT1215) package, configured as two diodes in series with shared cathode/anode terminal (Pin 3/4). It delivers trr ≤ 4 ns reverse recovery time, VR = 90 V maximum reverse voltage, and Cd ≤ 2 pF capacitance-enabling fast signal routing and polarity protection in space-constrained automotive and industrial PCBs.
For engineers reviewing the BAV99QAZ datasheet, BAV99QAZ pinout, BAV99QAZ application, or BAV99QAZ equivalent, this device is selected for high-speed switching nodes requiring AEC-Q101 qualification, low-profile mounting (0.37 mm height), AOI-compatible side pads, and dual-diode series topology for compact reverse polarity or clamping circuits.
Technical Context
The BAV99QAZ integrates two discrete high-speed switching diodes in a single ultra-small DFN1010D-3 package with shared terminal (Pin 3/4 serving as K1 and A2), forming a series-connected pair ideal for bidirectional clamping or cascaded switching paths. Its architecture supports independent forward conduction per diode while enabling common-node biasing.
Thermal performance is defined by Rth(j-a) = 410 K/W (FR4, standard footprint) and Rth(j-sp) = 265 K/W (with 1 cm² cathode pad), supporting operation up to Tj = 150 °C. The device is qualified to AEC-Q101, confirming robustness under automotive thermal cycling, humidity, and mechanical stress conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 90 V - supports 24 V and 48 V automotive bus protection without derating. |
| Reverse Recovery Time (trr) | 4 ns - enables >100 MHz switching in RF front-end clamping and data line protection. |
| Diode Capacitance (Cd) | 2 pF at 0 V, 1 MHz - minimizes signal distortion in high-frequency analog and digital I/O lines. |
| Forward Current (IF) | 290 mA per diode - sufficient for logic-level signal steering and low-power load switching. |
| Leakage Current (IR) | 0.5 µA at VR = 80 V, 25 °C - ensures stable DC blocking in battery-backed and always-on circuits. |
| Package Height | 0.37 mm - enables co-placement with 0201 passives and thin-profile connectors in ultra-dense layouts. |
Pinout & Package
BAV99QAZ uses the DFN1010D-3 (SOT1215) package: 1.1 × 1.0 × 0.37 mm body with visible, solderable side pads and no leads. Thermal pad is absent; heat dissipation relies on copper area under terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode (Diode 1) | Input node for first diode in series chain; connects to source of protected signal or power rail. |
| 2 | Cathode (Diode 2) | Output node of second diode; ties to load or reference point after series conduction path. |
| 3 & 4 | Cathode (Diode 1) / Anode (Diode 2) | Shared internal node-enables series connection without external trace; must be routed as single net. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive underhood and infotainment applications per stress test requirements. |
| AOI-compatible side pads | Enables automated optical inspection of solder joints without X-ray, reducing post-reflow QA cost. |
| Ultra-low profile (0.37 mm) | Permits stacking beneath low-clearance shields or adjacent to tall components like SOD-123 regulators. |
| Low leakage (0.5 µA @ 80 V) | Maintains signal integrity in high-impedance sensor interfaces and battery monitoring circuits. |
| Series diode topology | Reduces board area vs. discrete dual-diode placement; eliminates one interconnect trace in polarity guard paths. |
Applications
| Automotive CAN Transceiver Protection | USB 2.0 Data Line Clamping |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed dual-diode series applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W,115 | Same die, but in SOT323 package (1.7 × 1.3 × 0.95 mm); trr = 4 ns, VR = 70 V. | Larger footprint and 2.5× height limits use in ultra-thin modules; lacks AEC-Q101 certification. | Select when board real estate allows larger package and automotive qualification is not required. |
| NSR0230P2T5G | Single Schottky diode (30 V VR, 200 mA IF); no series topology; Cd = 15 pF; trr not specified (Schottky). | Cannot replicate series-clamp function; higher capacitance degrades >10 MHz signals; unsuitable for 90 V rails. | Only viable for low-voltage (<30 V), low-frequency (<10 MHz) polarity guard where size is secondary. |
Compared with BAV99W,115, BAV99QAZ offers 28% lower profile and AEC-Q101 compliance for automotive use; versus NSR0230P2T5G, it provides true series diode functionality, 90 V rating, and 7× lower capacitance-critical for high-speed signal integrity.

FAQ
What is the maximum continuous forward current per diode in BAV99QAZ?
The BAV99QAZ supports 290 mA per diode when mounted on an FR4 PCB with single-sided copper and standard footprint (per datasheet Table 1). At elevated ambient temperatures, derating applies: at 125 °C, usable current drops to ~120 mA per diode based on Fig. 2's derating curve.
Can Pin 3 and Pin 4 be used independently in PCB layout?
No-Pins 3 and 4 are internally bonded to the same node (K1/A2) and must be connected as a single net on the PCB. Splitting them violates the device's internal construction and risks open-circuit failure in the series diode path.
Is BAV99QAZ compatible with lead-free reflow profiles?
Yes-BAV99QAZ is rated for standard IPC/JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C. Figure 12 provides the recommended solder land pattern for DFN1010D-3, including solder paste coverage and stencil aperture guidance.
Does the 4 ns trr value apply under all operating conditions?
The 4 ns trr is measured under specific test conditions: IF = 10 mA, IR = 10 mA, IR(meas) = 1 mA, RL = 100 Ω, Tamb = 25 °C (Table 1 and Fig. 9). At higher currents or elevated junction temperatures, trr increases-e.g., to ~6 ns at Tj = 125 °C per typical characterization curves.
