Product details
Overview
BAV199-QVL from Nexperia is a low-leakage, medium-speed switching double diode in SOT23 package, with diodes connected in series. It delivers typ. 3 pA reverse leakage at 75 V/150 °C, 0.8 µs reverse recovery time, and supports 500 mA repetitive peak forward current. Used in automotive signal conditioning and precision bias networks where minimal leakage and fast switching are critical.
For engineers reviewing the BAV199-QVL datasheet, BAV199-QVL pinout, BAV199-QVL application, or BAV199-QVL equivalent, this page provides verified electrical parameters, validated SOT23 pin mapping, automotive-qualified thermal limits, and real-world use cases in ECU sensor interfaces and CAN bus protection circuits.
Technical Context
The BAV199-QVL integrates two epitaxial silicon diodes in a single SOT23-3 package with shared terminal (Pin 3 = K1/A2), enabling compact series-connected configurations for voltage clamping or dual-path signal routing. Its AEC-Q101 qualification confirms robustness under automotive thermal cycling and humidity stress.
Key performance stems from low-junction-capacitance (2 pF at 0 V) and tightly controlled reverse recovery (0.8 µs typ.), making it suitable for high-frequency analog front-ends and low-noise power rail monitoring where parasitic capacitance and leakage-induced offset must be minimized.
Key Specifications

Applications
| Automotive Sensor Signal Conditioning | CAN Bus Transceiver Protection |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-leakage dual diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BAV200-QVL | Higher leakage (10 pA typ. at 75 V/150 °C); same SOT23 pinout and VRRM | Less suitable for sub-µA bias networks but acceptable in general-purpose clamping | Select when cost sensitivity outweighs ultra-low leakage requirement |
| NSR0230P2T5G | Single Schottky diode (not dual); VF = 0.35 V typ.; no series configuration | Cannot replicate series-clamp topology; lacks shared terminal architecture | Use only for low-VF single-path rectification, not dual-diode signal conditioning |
Compared with BAV200-QVL and NSR0230P2T5G, the BAV199-QVL uniquely combines AEC-Q101 qualification, 3 pA leakage, and integrated series topology - making it irreplaceable in automotive sensor bias chains requiring both ultra-low leakage and compact dual-diode functionality.

FAQ
What is the maximum continuous forward current per diode at 100 °C ambient temperature?
At Tamb = 100 °C, the maximum permissible continuous forward current is 100 mA per diode when mounted on an FR4 PCB with single-sided copper. This value is derived from Figure 1 in the datasheet and accounts for thermal derating due to increased junction-to-ambient resistance at elevated temperatures.
Can BAV199-QVL be used in place of two separate BAV199 diodes?
No - BAV199-QVL integrates two diodes in series with a shared internal node (Pin 3), whereas two discrete BAV199s offer independent anode/cathode terminals. The QVL variant cannot replicate parallel or isolated dual-diode configurations; its topology is fixed for series clamping or level-shifting.
Is the 3 pA leakage value guaranteed or typical?
The 3 pA value is typical at VR = 75 V and Tj = 150 °C; the datasheet specifies a maximum of 80 nA under those conditions. Designers targeting ultra-low leakage must verify worst-case behavior using the 80 nA max in reliability-critical calculations.
Does the SOT23 package support reflow soldering per J-STD-020?
Yes - the BAV199-QVL SOT23 package is qualified for standard lead-free reflow profiles per J-STD-020, with peak temperature up to 260 °C. Figure 9 provides the recommended reflow solder land pattern, including 0.6 mm pad width and 0.7 mm solder paste stencil opening.
