BAV99

BAV99 Description

The BAV99 from Panasonic Electronic Components is a general-purpose diode array configured as 1 pair series connection, housed in a compact SOT23-3 surface-mount package. Designed for small-signal applications with currents up to 200mA (DC), it offers a reverse voltage (Vr) of 80V and a low forward voltage (Vf) of 1.25V at 150mA, ensuring efficient performance in low-power circuits. With a fast reverse recovery time (trr) of 3ns, it is suitable for high-speed switching applications. The device operates within a junction temperature range of up to 150°C and exhibits minimal reverse leakage current (100nA @ 80V), enhancing reliability.

BAV99 Features

• High-Speed Switching: 3ns trr enables rapid response in digital and RF circuits.
• Low Power Loss: 1.25V Vf (max) reduces energy dissipation in low-voltage applications.
• Robust Voltage Handling: 80V reverse voltage rating ensures durability in transient-prone environments.
• Compact & Reliable: SOT23-3 package with MSL 1 (Unlimited) moisture sensitivity, ideal for automated assembly.
• Low Leakage: 100nA @ 80V minimizes standby power consumption.

BAV99 Applications

The BAV99 excels in:

• Signal Clipping & Protection: Used in TVS diode arrays for ESD protection in communication interfaces (USB, HDMI).
• High-Speed Logic Circuits: Ideal for Schottky diode alternatives in TTL/CMOS level-shifting applications.
• RF & Switching Systems: Fast recovery suits mixers, detectors, and pulse shaping in RF modules.
• Power Management: Efficient reverse polarity protection in battery-powered devices.

Conclusion of BAV99

The BAV99 stands out for its balance of speed, low forward voltage, and high reverse voltage tolerance, making it a versatile choice for small-signal and high-frequency designs. Its SMT compatibility and low leakage further enhance its suitability for modern portable electronics, automotive systems, and industrial controls. While marked obsolete, it remains a reliable option for legacy or cost-sensitive projects requiring proven performance.
