Product details
Overview
BAV99QC from Nexperia is a dual-series high-speed switching diode pair in a 3-terminal DFN1412D-3 (SOT8009) leadless SMD package, configured as two diodes sharing a common terminal (A1–K1/A2–K2). It delivers trr ≤ 4 ns reverse recovery time, VR = 100 V, IF = 215 mA per diode, and Cd ≤ 1.5 pF at 1 MHz, enabling compact, high-frequency signal routing in space-constrained DC-DC converters and USB port protection circuits.
For engineers reviewing the BAV99QC datasheet, BAV99QC pinout, BAV99QC application, or BAV99QC equivalent, this page provides verified pin functions, real-world switching performance metrics, AOI-compatible solder joint validation, and direct alternatives for dual-diode polarity control and transient clamping designs.
Technical Context
The BAV99QC integrates two independent high-speed switching diodes in series configuration with shared central terminal (Pin 3 = K1/A2), forming a compact bidirectional path for signal steering or polarity reversal. Its ultra-low trr (≤4 ns) and sub-2 pF capacitance support >100 MHz switching in RF front-end bias networks and fast logic-level translation.
Thermal resistance Rth(j-a) = 375 K/W and Tj(max) = 150 °C enable reliable operation under pulsed forward currents up to 500 mA (IFRM), while side-wettable flanks ensure automated optical inspection compatibility on fine-pitch PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Recovery Time (trr) | ≤4 ns - Enables clean edge transitions in >100 MHz digital signal routing and pulse shaping. |
| Reverse Voltage (VR) | 100 V - Supports input protection in 24 V industrial I/O and 48 V PoE-powered interfaces. |
| Forward Current (IF) | 215 mA per diode - Sustains continuous operation in low-power LED drivers and sensor biasing. |
| Diode Capacitance (Cd) | 1.5 pF at 0 V, 1 MHz - Minimizes signal loading in high-impedance analog switch paths and RF detector inputs. |
| Forward Voltage (VF) | 855 mV at 10 mA - Ensures low conduction loss in battery-powered reverse polarity guards and level shifters. |
| Reverse Leakage (IR) | 0.5 µA at 80 V, 25 °C - Maintains signal integrity in high-Z sample-and-hold and precision reference paths. |
| Package Dimensions | 1.4 mm × 1.2 mm × 0.48 mm - Fits 0402-class footprints with 0.8 mm pitch, reducing board area by 40% vs. SOT-23. |
Pinout & Package
Encapsulated in the DFN1412D-3 (SOT8009) ultra-small leadless package with side-wettable flanks for AOI-compliant reflow soldering and 0.5 mm max profile height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode of Diode 1 (A1) | Input node for first diode's forward conduction path; connects to source in reverse polarity protection. |
| 2 | Cathode of Diode 2 (K2) | Output node for second diode's forward path; ties to load in series-switching configurations. |
| 3 | Cathode of Diode 1 / Anode of Diode 2 (K1/A2) | Shared internal node enabling series connection - critical for bidirectional clamping and voltage doubling topologies. |
Key Features
| Feature | Design Value |
|---|---|
| High-Speed Switching | trr ≤ 4 ns ensures minimal timing skew in clock distribution and data line steering applications. |
| Ultra-Small Footprint | 1.4 mm × 1.2 mm body reduces PCB area by ≥35% versus SOT-23 dual-diode packages. |
| Side-Wettable Flanks | Enables automated optical inspection of solder joints without X-ray, improving manufacturing yield. |
| Low Capacitance | 1.5 pF at zero bias preserves signal rise/fall times in high-speed USB 2.0 and LVDS interface protection. |
| Low Profile | 0.48 mm max height supports stacking under shields and integration into ultra-thin portable devices. |
Applications
| USB Port Protection | DC-DC Converter Snubber |
|---|---|
|
Use Scenario: Protecting USB 2.0 data lines against ESD and overvoltage events during hot-plug insertion. IC Role / Device Role / Timing Role: Dual-diode clamp between D+ and D− lines, with shared center terminal grounded or biased to VBUS. Use Value: 4 ns trr prevents data corruption during 100 Mbps signaling; 1.5 pF capacitance avoids signal integrity degradation. |
Use Scenario: Suppressing voltage spikes across MOSFET switches in synchronous buck converters operating at 500 kHz–2 MHz. IC Role / Device Role / Timing Role: Fast-recovery snubber diode placed across high-side FET drain-source to absorb inductive kickback. Use Value: 100 V VR rating handles 24 V input transients; 215 mA IF supports continuous snubbing in 3 A output designs. |
| Reverse Polarity Guard | Signal-Level Translation |
|
Use Scenario: Preventing damage from incorrect battery or adapter insertion in portable medical monitors and handheld test equipment. IC Role / Device Role / Timing Role: Series-connected diode pair (A1→K1/A2→K2) inserted in power rail with center terminal tied to load ground. Use Value: 855 mV VF at 10 mA limits voltage drop to <1 V at 100 mA loads; 0.5 µA IR ensures standby current <1 µA. |
Use Scenario: Level-shifting 3.3 V logic signals to 5 V domains in mixed-voltage microcontroller peripherals. IC Role / Device Role / Timing Role: Clamp diode network using shared terminal to define threshold offset between logic families. Use Value: Matched VF characteristics across both diodes (<150 mV spread) ensure consistent translation thresholds; 4 ns trr avoids metastability in 20 MHz clock domains. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-series high-speed switching diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV99W,115 | Same die in SOT-323 package; larger footprint (2.1 mm × 1.25 mm), no side-wettable flanks. | Lacks AOI support; unsuitable for fine-pitch automated assembly but offers easier manual rework. | Select when legacy footprint compatibility or hand-soldering repairability outweighs miniaturization needs. |
| PMEG3010CEAX | Single Schottky diode (30 V, 1 A); lower VF (~350 mV), higher IF, but no dual-series topology. | Cannot replicate shared-terminal series configuration; requires discrete layout for dual-path functions. | Choose only for single-diode forward conduction roles where ultra-low VF dominates over topology fidelity. |
Compared with BAV99W,115, the BAV99QC saves 42% board area and enables AOI; versus PMEG3010CEAX, it retains essential dual-diode series functionality for polarity control and clamping-making it irreplaceable in topologies requiring K1/A2 node access.

FAQ
What is the maximum junction temperature for continuous operation?
The BAV99QC has a rated maximum junction temperature (Tj) of 150 °C, validated under steady-state conditions with FR4 PCB mounting (single-sided 70 μm copper, tin-plated). Derating begins above Tamb = 85 °C, and thermal resistance Rth(j-a) is 375 K/W in free air - design must ensure power dissipation stays below 335 mW at ambient ≤25 °C.
Can Pin 3 be used as a standalone anode or cathode?
No - Pin 3 is internally bonded as the cathode of Diode 1 and anode of Diode 2 (K1/A2). It cannot function independently; its electrical behavior is defined solely by the series-connected diode pair. Using it as a floating node violates the device's internal structure and may cause unpredictable conduction or breakdown.
Is the BAV99QC suitable for automotive applications?
No - per Nexperia's revision history (v.2, July 2023), the BAV99QC is explicitly designated as non-automotive. It lacks AEC-Q200 qualification, automotive-grade process controls, and extended temperature validation. For automotive use, select the -Q qualified variant (e.g., BAV99QC-Q).
How does the side-wettable flank design impact reflow profiling?
The side-wettable flanks require standard lead-free reflow profiles (peak 260 °C, 60 s max above 217 °C) but demand precise stencil aperture design: recommended solder paste volume is 0.1 mm thickness with 0.45 mm × 0.75 mm land pattern (per Fig. 7). Underfill or insufficient paste causes voiding; excess paste bridges Pins 1–2 or 2–3 due to 0.8 mm pitch.
