BAV74

BAV74 Description

The BAV74 from Siemens is a high-performance general-purpose diode array designed for small-signal applications with a maximum DC reverse voltage (Vr) of 50V and an average rectified current (Io) of 200mA per diode. Packaged in SOT23-3, this surface-mount device features a 1 Pair Common Cathode configuration, making it ideal for compact PCB designs. With a fast reverse recovery time (trr) of just 4ns, the BAV74 excels in high-speed switching applications while maintaining low leakage current (100nA @ 50V). Its forward voltage (Vf) is a maximum of 1.25V @ 100mA, ensuring efficient power handling.

BAV74 Features

• High-Speed Performance: Optimized for <200mA small-signal applications with a 4ns trr, enabling rapid switching.
• Low Leakage: Minimal reverse leakage (100nA @ 50V) enhances energy efficiency.
• Robust Construction: Junction temperature rating of 150°C ensures reliability in demanding environments.
• Compact & Versatile: SOT23-3 package suits space-constrained designs, while common-cathode configuration simplifies circuit layout.
• Compliance & Reliability: REACH Affected, EAR99 (ECCN), and MSL 1 (Unlimited) rated for broad industrial use.

BAV74 Applications
