BAV70

BAV70 Description

The BAV70 from Taiwan Semiconductor Corporation is a high-performance general-purpose diode array designed for small-signal and switching applications. Packaged in a compact SOT-23 surface-mount form factor, it features a 1 Pair Common Cathode configuration, making it ideal for space-constrained PCB designs. With a 70V DC reverse voltage (Vr) and 200mA average rectified current (Io) per diode, the BAV70 delivers reliable performance in low-power circuits. Its fast reverse recovery time (trr) of 6 ns ensures efficient switching, while the low forward voltage drop (1.25V @ 150mA) minimizes power dissipation.

BAV70 Features

• High-Speed Switching: Optimized for small-signal applications with a trr of 6 ns, enabling rapid response in digital and RF circuits.
• Low Leakage Current: 2.5 µA @ 70V reverse leakage ensures minimal power loss in standby modes.
