Infineon BAT68-04: High-Performance Schottky Diode for RF and Small Signal Applications

In the realm of RF (Radio Frequency) and small-signal circuitry, component selection is critical to achieving optimal performance. The Infineon BAT68-04 stands out as a premier surface-mount Schottky diode, engineered specifically for high-frequency applications where low loss, fast switching, and minimal noise are paramount.

This diode is part of a series renowned for its very low forward voltage and extremely fast switching speed. Constructed using a sophisticated platinum barrier technique, the BAT68-04 ensures excellent performance in sensitive circuits. Its primary function is signal demodulation, mixing, and switching in devices such as mobile phones, satellite receivers, test equipment, and high-speed data communication systems.

A key advantage of the BAT68-04 is its exceptionally low capacitance, typically around 0.65 pF at 0 V, 1 MHz. This minimal capacitance is crucial for RF applications as it prevents signal loading and preserves signal integrity at high frequencies. Furthermore, its low series resistance contributes to a very small forward voltage drop, enhancing efficiency, especially in low-power or small-signal environments.

The device is housed in a compact SOT-23 package, making it ideal for space-constrained PCB designs. Its robust construction ensures high reliability, while its lead-free and RoHS-compliant design meets modern environmental standards.
