Features
- Type: Silicon epitaxial planar diode
- Package: SOD-323 (small surface-mount)
- Max Reverse Voltage (VR): 250V
- Max Forward Current (IF): 200mA
- Forward Voltage (VF): ~1V at 10mA
- Reverse Recovery Time (trr): 4ns (fast switching)
- Applications: High-speed switching, rectification, clamping, and protection circuits
It is commonly used in low-power circuits, signal processing, and high-frequency applications due to its fast response and compact size.
Application
1. Signal Demodulation – Extracting signals in RF and communication circuits.
2. Switching Circuits – Fast switching in digital and logic circuits.
3. Protection Circuits – Clamping and transient voltage suppression.
4. Rectification – Low-power AC-to-DC conversion.
5. High-Frequency Applications – Mixers, detectors, and modulators in RF systems.
Its small-signal performance and fast recovery make it suitable for high-speed applications.
