Product details
Overview
BAV99-QVL from Nexperia is a dual high-speed switching diode in SOT23 package, configured as two independent diodes sharing a common terminal (anode of D1 and cathode of D2 tied to pin 3). It delivers trr ≤ 4 ns reverse recovery time, Cd ≤ 1.5 pF capacitance, and VR = 100 V, enabling use in automotive-grade polarity protection and signal routing circuits.
For engineers reviewing the BAV99-QVL datasheet, BAV99-QVL pinout, BAV99-QVL application, or BAV99-QVL equivalent, this dual diode supports high-frequency switching up to 100 MHz, meets AEC-Q101 qualification, and provides low-leakage operation (IR ≤ 0.5 µA at 80 V) for robust ECU input conditioning and USB port protection designs.
Technical Context
The BAV99-QVL integrates two discrete high-speed diodes in a single SOT23-3 package with shared terminal architecture (pin 3 = K1/A2), enabling compact dual-path clamping or steering without external interconnects. Its silicon epitaxial construction ensures consistent trr ≤ 4 ns under IF = 10 mA / IR = 10 mA test conditions and maintains VF ≤ 855 mV at 10 mA.
Thermal resistance Rth(j-a) = 500 K/W (free air) and Rth(j-sp) = 360 K/W support reliable operation up to Tj = 150 °C. The device is rated for IF = 215 mA per diode and Ptot = 250 mW at Tamb ≤ 25 °C on FR4 PCB with standard footprint.

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 | SOT323 package (smaller footprint: 2.1 mm × 1.25 mm), identical electrical specs | Better suited for space-constrained portable electronics; lower thermal mass affects pulse-current derating | Select when board area is critical and thermal cycling is limited to ≤ 10⁴ cycles |
| MMBD7000LT1G | trr = 4 ns (same), but VR = 70 V and IR = 1 µA at 50 V - lower voltage rating and higher leakage | Not AEC-Q101 qualified; suitable only for consumer-grade 5 V/12 V systems | Choose only for cost-sensitive non-automotive designs where 100 V standoff is not required |
Compared with BAV99-QVL, BAV99W-Q offers identical performance in a smaller footprint but reduced thermal margin, while MMBD7000LT1G trades automotive qualification and 100 V rating for lower unit cost in non-critical applications.

FAQ
What is the maximum junction temperature for continuous operation of BAV99-QVL?
The BAV99-QVL has a maximum junction temperature (Tj) of 150 °C, validated under steady-state conditions with Ptot = 250 mW at Tamb ≤ 25 °C on FR4 PCB. Derating is required above 25 °C ambient per Rth(j-a) = 500 K/W, reaching zero power at 150 °C ambient.
Can BAV99-QVL be used in bidirectional TVS configurations?
No - BAV99-QVL is not a TVS diode. It lacks avalanche breakdown capability and is rated only for 100 V repetitive reverse voltage. For bidirectional transient suppression, use dedicated AEC-Q101 TVS arrays like PESD5V0S1BA.
Is pin 3 truly electrically isolated between the two diodes?
No - pin 3 is internally connected to both the cathode of diode 1 and anode of diode 2. This shared terminal defines the dual-diode topology and must be treated as a single net; it cannot serve as an isolated reference point for independent biasing.
Does the 4 ns trr specification apply across the full operating temperature range?
The 4 ns trr is specified at Tamb = 25 °C. At 150 °C junction temperature, trr increases to ≤ 6 ns per characterization data in Figure 4 of the datasheet, due to carrier lifetime extension at elevated temperatures.
