BAV99L-AQ by Diotec Semiconductor: Small Diode - Big Difference in Timing

In modern vehicles, not every electronic fault announces itself loudly. Some show up as barely noticeable delays - a dashboard light that blinks a moment late or a control loop that feels slightly out of rhythm. These small drifts often originate in the silicon, where switching speed decides signal integrity.

Diotec's BAV99L-AQ small-signal diode addresses this challenge by keeping automotive electronics precise and predictable. This dual high-speed device provides < 4 ns switching 100 V / 2 × 125 mA capability. It is fully AEC-Q101 qualified, ensuring that it meets stringent automotive reliability standards.

Already used across dashboards - from comfort controls to infotainment and lighting systems - the component keeps logic transitions sharp and predictable. Even when temperature or load or lifetime would slow lesser parts down.

In an era where automotive precision increasingly depends on quiet, flawless timing, the BAV99L-AQ aims to ensure every switch happens exactly when it should.
