TVS-Diodes: 1.5KE220CA-TP Application Field and Working Principle

The 1.5KE220CA-TP is a transient voltage suppressor diode, designed to protect electronic systems from lightening, electrostatic shock and other forms of wide voltage transients. It is one of the diodes used in the TVS-Diode technology - Transient Voltage Suppression diode which safely and quickly diverts high surges to ground without causing any circuit damage.

Application Fields of 1.5KE220CA-TP TVS-Diodes

The 1.5KE220CA-TP TVS-Diode is advantageous in a range of applications such as lightning protection and electrostatic discharge protection (ESD) in extremely noise-sensitive equipment and systems. It is used in automotive industries, military, medical and industrial electronics, cellular phones, and telecom systems to protect against voltage transients. It has been widely used in the voltage clamping of power lines and data lines such as USB, HDMI, IEEE1394 and power lines in order to protect electronic devices from lightning strikes.

Working Principle of 1.5KE220CA-TP TVS-Diodes

The 1.5KE220CA-TP TVS-Diode provides consistent voltage clamping regardless of the noise source and voltage amplitude. It uses special double-diffused silicon technology to achieve electrostatic discharge (ESD) withstand voltage up to 22kV. Unlike normal rectifying diodes, the TVS-Diode operates in two ways: clamping and transient absorption. When a transient voltage spike hits the input signal, the 1.5KE220CA-TP acts in a clamping way, suppressing the transient voltage and preventing it from passing to the output. It also works by using avalanche breakdown, a nonlinear process in which an avalanche of minority carriers is produced within the P-N junction of the diode when subjected to a certain level of reverse voltage bias and hence large current flows in the junction. This high current is then rapidly absorbed and safely diverted to ground, acting as a power absorber. This prevents the damage caused by the overvoltage transients.

Conclusion

The 1.5KE220CA-TP TVS-Diodes provide robust overvoltage protection, high current handling capability and fast response time for a range of applications across various industries. The 1.5KE220CA-TP is especially designed to effectively protect electronic systems from lightening, electrostatic shock and other forms of voltage transients, ensuring increased reliability and protection. The diode combines clamping and absorption technologies to quickly disburse voltage spikes, providing robust protection from damage caused by transients.
