Additional Details:
The 1N4148W-A2-L diode typically has a forward voltage drop of around 0.7V at a forward current of 10mA, a reverse breakdown voltage of at least 75V, and a reverse recovery time of typically 4ns. It has a maximum forward current rating of 200mA. It is available in a small surface mount package (SOD-123 or similar). The 1N4148 is one of the most commonly used diodes due to its fast switching speed and general-purpose characteristics. Its relatively low capacitance makes it useful in high-frequency applications. The 'A2' marking may indicate specific electrical characteristics or quality control measures applied during manufacturing by Panjit.
