TVS - Diodes

A transient voltage suppression (TVS) diode is a general term for protective devices used in a wide range of applications where power spikes or other forms of over-voltage protection is required. In general, these devices are used to absorb and divert voltage and to protect other components from transient over-voltage conditions, such as spike voltages, caused by electrostatic discharge (ESD), lightning, inductive switching, and other high-energy surges that could damage or destroy other components.

824520241 Application Field and Working Principle

The 824520241 is a type of TVS diode and is designed to protect sensitive electronic systems from voltage and current spikes. The 824520241 is a bi-directional, unidirectional diode with a maximum voltage rating of 8.2 V and 20 A current carrying capability. The device features a low on-state resistance and zero reverse leakage current, providing superior protection and reliable operation.

The working principle of a TVS diode is simple. In normal operation, the diode allows current to flow in one direction only, usually from anode to cathode. When the voltage across the diode exceeds a certain level, known as the Peak Inverse Voltage (PIV), the PN junction of the diode will break down, allowing current to flow in the opposite direction. This allows the device to absorb and divert the extra voltage and protect other components from the over-voltage condition.

The 824520241 is widely used in automotive applications, such as airbags, crash sensors, and powertrain control units, as well as industrial, medical, and communication systems. It is also suitable for use in consumer electronics devices such as mobile phones, tablets, and computers.

The device features built-in overvoltage protection that is triggered when the device’s voltage rating is exceeded. The diode’s current-limiting feature helps prevent the device from burning out and damaging connected components or systems. Additionally, it offers excellent surge absorption capability and has a low clamping voltage which helps minimize power dissipation.

The 824520241 can also be used to protect low-voltage circuits from overcurrent and short-circuit conditions. The device is designed to sense a current overload and then clamp the voltage at a predetermined level, safely diverting the current flow away from critical components.

The 824520241 is designed for use in environments where power spikes and electrostatic discharges occur frequently. It is an effective and economical option for protecting sensitive electronic circuits and devices from high-energy transients.
