TVS - Diodes

Transient Voltage Suppression (TVS) diodes are a type of semiconductor used to protect equipment from electrical transients. They are commonly used in applications where transients can cause damage to sensitive equipment, such as communications, power supplies, and microcontrollers. The TP6KE62CA is a TVS diode designed to protect against voltage transients in applications that require a low capacitance and a fast response time. This article outlines the application field and working principle of the TP6KE62CA.

Application field

The TP6KE62CA is a bi-directional television signal surge protector. It is designed to protect sensitive equipment from voltage surges caused by lightning, line transients, and electrostatic discharge. It is suitable for both digital and analog broadcast television applications, such as coaxial cable and antenna connections. It is UL recognized and RoHS compliant. The TVS diode can handle transient voltages up to 6kV peak.

Working principle

The TP6KE62CA is a unidirectional diode array. It is comprised of two independent diodes, each connected in a reverse-biased (clamped) state. The two diodes are connected in a series configuration and together form a junction. The TVS diode is operated in a reverse polarity mode, meaning when a transient voltage is detected, the diode’s junction will act as a short to ground. This prevents the voltage from reaching the protected equipment. The device has low clamping voltage and fast response time.

Conclusion

The TP6KE62CA is an efficient TVS diode designed to provide protection from voltage transients. It is suitable for applications that require low capacitance and fast response time. The device is UL recognized and RoHS compliant and can handle transient voltages up to 6kV peak. The diode is operated in a reverse polarity mode, meaning it acts as a short to ground when a transient voltage is present. This prevents the voltage from reaching the protected equipment.
