Description
A diode is a device which allows current flow through only one direction. That is the current should always flow from the Anode to cathode. The cathode terminal can be identified by using a grey bar as shown in the picture above.
For IN4148 Diode, the maximum current carrying capacity is 300mA, it can withstand peaks up to 2A. The speciality of this diode is its fast recovery time of 8ns at a forward current of 10mA, hence this diode is used in places where fast switching are involved.
Applications of Diodes
- Can be used to prevent reverse polarity problem
- Protect Power electronic switches that are operating with high switching frequency.
- Half Wave and Full Wave rectifiers
- Used as a protection device
- Current flow regulators
