Product details
Overview
BAV99QC-Q from Nexperia is a dual-series high-speed switching diode pair in a 3-terminal DFN1412D-3 (SOT8009) leadless SMD package, featuring trr ≤ 4 ns, VR = 100 V, Cd ≤ 1.5 pF, IF = 215 mA per diode, and AEC-Q101 qualification for automotive use - deployed in reverse polarity protection and space-constrained DC/DC converter bias networks.
For engineers reviewing the BAV99QC-Q datasheet, BAV99QC-Q pinout, BAV99QC-Q application, or BAV99QC-Q equivalent, key selection criteria include ultra-fast recovery time, side-wettable flank compatibility with AOI, low-profile 0.48 mm body height, and dual-diode series configuration enabling compact bidirectional clamping or level-shifting functions.
Technical Context
This dual-series diode integrates two discrete high-speed switching diodes sharing a common terminal (Pin 3 = K1/A2), forming a back-to-back anode-cathode-anode chain ideal for signal steering and transient suppression without external interconnects. Its architecture eliminates parasitic inductance between diodes found in discrete solutions.
Designed for operation up to 150 °C junction temperature and qualified per AEC-Q101, it delivers stable trr ≤ 4 ns under IF = 10 mA / IR = 10 mA test conditions and maintains IR ≤ 0.5 µA at VR = 80 V and 25 °C - critical for low-leakage hold-off in always-on automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 100 V - supports 48 V automotive bus transients and 24 V industrial supply rail clamping. |
| Reverse Recovery Time (trr) | 4 ns - enables >100 MHz switching in snubberless flyback controllers and high-frequency signal routing. |
| Forward Current (IF) | 215 mA per diode - sufficient for LED bias, logic-level translation, and low-power gate driving. |
| Diode Capacitance (Cd) | 1.5 pF at 0 V - minimizes signal distortion in RF detector and high-speed data line protection. |
| Package Dimensions | 1.4 mm × 1.2 mm × 0.48 mm - reduces PCB area by >50% vs. SOT-23 while enabling AOI-compatible solder joint inspection. |
| Junction Temperature (Tj) | 150 °C - ensures reliability in engine control unit (ECU) and ADAS camera module ambient environments. |
Pinout & Package
Encapsulated in the DFN1412D-3 (SOT8009) leadless plastic package with side-wettable flanks, 0.8 mm pitch, and 0.48 mm profile - optimized for reflow soldering and automated optical inspection 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 source of protected signal or power rail. |
| 2 | Cathode of Diode 2 (K2) | Output node of second diode; ties to load or reference ground in polarity protection configurations. |
| 3 | Cathode of Diode 1 / Anode of Diode 2 (K1, A2) | Shared internal node enabling series connection - eliminates trace inductance and saves board space. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - suitable for under-hood and infotainment systems. |
| Side-wettable flanks (SWF) | Enables automated optical inspection of solder fillets on all three terminals - improves yield in high-volume automotive SMT lines. |
| Ultra-low profile (0.48 mm) | Permits placement beneath connectors or near heat sinks where Z-height is constrained - e.g., in compact telematics modules. |
| Low leakage (IR ≤ 0.5 µA @ 80 V) | Maintains signal integrity in always-on wake-up circuits and battery-monitoring paths with minimal standby current drain. |
Applications
| Reverse Polarity Protection | High-Speed Signal Clamping |
|---|---|
|
Use Scenario: Protecting 12 V/24 V automotive ECUs from incorrect battery connection during service or assembly. IC Role / Device Role / Timing Role: Series-connected diode pair acts as low-loss forward conduction path while blocking reverse voltage above −100 V. Use Value: Eliminates need for external MOSFET-based protection ICs; achieves <1.25 V forward drop at 150 mA with no gate drive complexity. |
Use Scenario: Limiting analog sensor output swing (e.g., Hall-effect or IMU signals) to microcontroller ADC input range. IC Role / Device Role / Timing Role: Dual-diode clamp referenced to VDD and GND, leveraging shared terminal for symmetrical clipping. Use Value: 4 ns trr prevents signal overshoot distortion; 1.5 pF capacitance avoids loading high-impedance sensor outputs. |
| Space-Constrained DC/DC Bias Networks | Automotive CAN Transceiver Protection |
|
Use Scenario: Providing bootstrap and auxiliary bias paths in compact buck-boost converters for ADAS camera modules. IC Role / Device Role / Timing Role: High-speed switching diode pair supplies isolated gate drive charge and feedback path rectification. Use Value: 215 mA per diode rating supports 3 W converter operation; 0.48 mm height fits beneath inductor footprints. |
Use Scenario: Transient voltage suppression on CAN_H/CAN_L lines in junction box and gateway ECUs. IC Role / Device Role / Timing Role: Paired diodes configured as low-capacitance TVS front-end to absorb ISO 7637-2 pulse 1/2a/5a energy. Use Value: 100 V VR withstands load dump events; AEC-Q101 qualification ensures immunity to automotive thermal and vibration stress. |
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-Q | Same die, but in SOT-323 package (2.1 mm × 1.25 mm × 1.1 mm); no side-wettable flanks. | Larger footprint and 2.3× taller - unsuitable for AOI or ultra-thin modules; higher Rth(j-a) = 450 K/W. | Select when legacy SMT lines lack SWF inspection capability or board stack height allows ≥1.1 mm clearance. |
| PMEG3010CPA | Single Schottky diode (30 V, 1 A, VF = 0.38 V), not dual-series; no shared terminal architecture. | Cannot replicate series-clamp or reverse-polarity topology; lower VR limits use to 12 V systems only. | Choose only for unidirectional low-VF rectification where dual-diode functionality is unnecessary. |
Compared with BAV99W-Q and PMEG3010CPA, the BAV99QC-Q uniquely combines AEC-Q101 compliance, 0.48 mm Z-height, side-wettable flanks, and integrated dual-series topology - making it the only option supporting AOI-verified reverse polarity protection in sub-1 mm automotive modules.

FAQ
What is the maximum continuous forward current rating per diode in the BAV99QC-Q?
The BAV99QC-Q supports 215 mA continuous forward current per diode at Tamb = 25 °C on FR4 PCB with standard footprint and single-sided 70 μm copper. Derating applies above 25 °C ambient, reaching 125 mA when both diodes conduct simultaneously.
Does the BAV99QC-Q support Automated Optical Inspection (AOI)?
Yes - its DFN1412D-3 (SOT8009) package features side-wettable flanks (SWF), allowing AOI systems to inspect solder fillet quality on all three terminals. This is confirmed in Section 2 of the official datasheet and supported by Nexperia's reflow footprint guidelines.
How is the shared terminal (Pin 3) electrically configured inside the BAV99QC-Q?
Pin 3 is internally connected to both the cathode of Diode 1 and the anode of Diode 2, forming a true series configuration (A1–K1/A2–K2). This eliminates external trace inductance between diodes and enables compact bidirectional clamping or polarity protection topologies.
Is the BAV99QC-Q suitable for 48 V automotive systems?
Yes - with VR = 100 V and AEC-Q101 qualification, it withstands ISO 7637-2 load dump pulses and operates reliably from −40 °C to +150 °C junction temperature, meeting requirements for 48 V mild-hybrid vehicle power distribution and control modules.
