Transient Voltage Suppression (TVS) diodes are devices used to protect vital components from electrical overstress (EOS) damage in circuit designs. These devices are designed to protect from conditions such as electrostatic discharge (ESD), surges, lightning, and other similar phenomena. The 15KP20C is a unidirectional TVS diode that is designed for use in a variety of applications including consumer electronics, automotive, telecom, and industrial applications.

The 15KP20C is a bidirectional, surface-mount device with a small size and low profile. It is a silicon avalanche diode with dynamic resistance in the range of 5-7 ohms. This device is constructed from a pair of silicon diodes in a common anode configuration. It offers a widely varying dynamic resistance from 15.5 volts to 20 volts

The 15KP20C can be used in a variety of applications due to its simplicity and strong protection capabilities. One of its primary uses is in consumer electronics. It can be used to protect critical components from EOS damage due to unexpected power events like lighting surges and ESD events. It can also be used to protect automotive, telecom, and industrial equipment from ESD and EOS damage as well.

The working principle of the 15KP20C is based on its ability to quickly switch from its normal low resistance state to a high resistance state when exposed to over voltage or over current. This process is known as the "avalanche breakdown effect". In its normal state, the device offers very low dynamic resistance in the range of 5-7 ohms. When exposed to an over voltage or over current, the device breaks down, which causes it to enter a high resistance state with a dynamic resistance up to 15.5 volts to 20 volts. This process is designed to protect the circuit components from EOS damage caused by the over voltage or over current.

The 15KP20C is an invaluable device for protecting sensitive and expensive electronic components from EOS damage. With its small size and low profile, it is ideal for a wide variety of applications including consumer electronics, automotive, telecom, and industrial equipment. Its avalanche breakdown effect allows it to precisely switch from its low resistance state to a high resistance state at the right moment to protect the circuit components from damage.
