BAV99W

BAV99W Description

The BAV99W from Diodes Incorporated is a surface-mount general-purpose diode array configured as 1 pair series connection, designed for high-speed switching and signal processing applications. With a maximum reverse voltage (Vr) of 100V and an average rectified current (Io) of 150mA per diode, it offers reliable performance in compact circuits. The diode features a low forward voltage drop (1.25V @ 150mA) and minimal reverse leakage current (2.5µA @ 75V), ensuring efficient power handling. Its ultra-fast reverse recovery time (4ns) makes it suitable for high-frequency applications. Although marked as obsolete, it remains a robust choice for legacy designs due to its RoHS3 compliance and REACH-unaffected status.
