TVS - Diodes

A Transient Voltage Suppression Diode, or TVS-Diodes, is a special purpose diode which is used to protect sensitive electronic components for high energy transient overvoltages. The 15KP120A-TP is a silicon bidirectional unidirectional application diode specifically designed to protect sensitive equipment such as computers, workstations, printers, monitors, memory and communication circuits from destructive high energy transients.

Applications of 15KP120A-TP

The 15KP120A-TP application diode family is designed for continuous protection circuits in industries like telecom, automotive, medical, home appliance, and industrial control etc. It integrates a multilayer element with optimized ESD protection and over-voltage protection for numerous applications. It provides ESD protection up to 15KV contact and is specifically designed to protect against high transverse voltage transients even in very high ESD disturbance fields. Its bidirectional structures provide reliable protection for both the positive and negative lines, making it suitable for use in a wide variety of electronic circuits.

Working Principle of 15KP120A-TP

When transient voltage overvoltages occur, the TVS-diode provides a low impedance path between the protected line and ground, thus preventing the protected components from getting damaged by the transients. The 15KP120A-TP is designed so that the avalanche breakdown voltage is about 30 volts above the supply voltage in normal operation. This ensures fast and reliable protection of the protected components from destructive high-voltage transients.When an overvoltage-induced transient occurs, the avalanche ratio of the diode causes a rapid current flow from the protection line to the ground, thus absorbing the destructive energy from the transients within a very short time. The 15KP120A-TP Diodes are designed to reduce the clamping voltage over the standard operating temperature range. This allows the protected components to remain in the normal operating voltage range while still providing secure protection.

Conclusion

The 15KP120A-TP application diode is a reliable transient voltage suppressor specifically designed to protect sensitive electronic components from destructive high voltage transients. It provides ESD protection up to 15KV contact as well as a wide range of built-in features and remedies that can be utilized to protect industrial control systems, telecoms equipment, computer systems, and other sensitive electronic devices. The working principle of this diode is based on its avalanche breakdown voltage, which causes a rapid current flow between the protection line and ground, effectively absorbing the destructive energy from the transients within a very short period of time. This makes the 15KP120A-TP diode an ideal solution for protecting sensitive components from voltage transients.
