1N4148WS-7-F FAQ
What is the green molding compound molded plastic case?
UL94V-0.
What is the method 208 standard?
MIL-STD-202.
What denotes cathode end polarity?
Color band.
What us a switching diode?
A switching diode is suitable for switching a small signal of up to 100 mA, acting as a rectifier. In contrast, a rectifier diode is used for AC line rectification (from alternating current to direct current). Switching diodes are designed to handle a voltage of less than tens of volts.
What are fast switching diodes used for?
The switching diode has the characteristics of fast switching speed, small size, long life, and high reliability. It is widely used in switching circuits, detection circuits, high-frequency and pulse rectification circuits, and automatic control circuits of electronic equipment.
