概要
Description
The BAS28 is a high-speed switching diode array, commonly used in signal processing, clipping, and protection circuits. It consists of two independent diodes in a single package, offering compact design and matched performance. Key features include:
- Low forward voltage (~0.7V) for efficient switching.
- Fast switching speed (typically 4ns), suitable for high-frequency applications.
- Small signal operation, ideal for logic circuits and RF applications.
Packaged in SOT-23 or similar, it’s widely used in:
- Signal demodulation
- Voltage clamping
- High-speed switching
Its dual-diode configuration saves board space while ensuring reliability. Check datasheets for exact specifications like reverse voltage (often ~75V) and current ratings.
