Working Principle

The CDBMT1100-HF works by using a PN junction between two semiconductor layers of n-type and p-type material. When a voltage is applied, the PN junction induces a weak electric field. This weak electric field enables the diode to conduct current in only one direction, forming a rectified current. This rectified current is used in a variety of applications, such as power supplies, audio electronics, and automotive electronics.

When a reverse voltage is applied to the diode, the electric field is reversed and no current can pass. This feature, known as reverse leakage current, helps to protect the circuit from accidental reverse voltage. The reverse leakage current of the CDBMT1100-HF is MAX.5 mA, which is extremely low and can provide the desired level of protection.
