It is an excellent choice for applications requiring a high-reliability and high-voltage tolerant rectifier device. The diode can withstand high transients and is an ideal alternative for applications where an avalanche diode is required.

Working Principle of SK54B-LTP

The SK54B-LTP operates on the principle of avalanche breakdown. When a positive voltage is applied to the anode of the diode, there is a small quantity of minority carriers that are injected into the intrinsic region (the region between the P and N layers) of the diode. This process of minority carrier injection causes lower resistance to the diode and hence resulting in an increase in current.

The increased current further leads to an increase in the electric field across the junction, eventually causing the voltage applied to reach a value at which the electric field becomes strong enough to break down the barriers. This phenomenon is called avalanche breakdown, which allows the diode to pass current even when a high voltage is applied.
