Switching Diode
witching diodes are optimized for high-speed on/off operation. Typical types: 2AK, 2DK, 1N4148, used in computers, pulse and switching circuits.
**Key Features**:
1. Low on-resistance, extremely high off-resistance, close to ideal electronic switch.
2. Small junction capacitance, excellent high-frequency switching performance.
3. Fast switching; reverse recovery time is several ns for silicon, hundreds of ns for germanium.
4. Small size, long life, high reliability, used in switching, detection, high-frequency rectification, automatic control.
