BAV99

BAV99 Description

The BAV99 from Nexperia is a dual series high-speed switching diode designed for precision applications requiring fast switching and low power dissipation. Encased in a compact SOT23 (TO-236AB) SMD plastic package, it offers excellent performance in space-constrained designs. With a maximum DC reverse voltage of 100V, peak forward voltage of 1.25V at 0.15A, and ultra-fast reverse recovery time of 4ns, this diode ensures efficient signal processing and minimal energy loss. Its low peak reverse current (0.5µA at 80V) and low capacitance (1.5pF max) make it ideal for high-frequency circuits. Compliant with EU RoHS and rated for 150°C maximum operating temperature, the BAV99 is engineered for reliability in demanding environments.
