TVS devices are used in many applications, ranging from consumer electronics to industrial and military applications. The B72590T7050S160 is a thermoset TVS (Transient Voltage Suppressor) that provides protection to circuits, devices, and components from damaging transient overvoltage events. It has a rated voltage of 160Vdc, a capacitance of 70pF, and 80mA peak pulse current rating.

The B72590T7050S160 is ideal for use in applications requiring a high voltage transient voltage suppression device, such as in automotive, telecommunications, industrial control, white goods, and consumer electronics. It is designed to protect sensitive electronic circuits and components against high voltage transients, such as those caused by electrostatic discharge (ESD), inductive load switching, and other transient events.

Working Principle

TVS devices, such as the B72590T7050S160, use a Zener diode to protect a sensitive electrical circuit from damage due to high voltage transients. The Zener diode acts as a kind of voltage regulator by providing a path for the transient current to be conducted away from the circuit. It does this by allowing current to flow in one direction only, thus preventing it from going into sensitive parts or devices.

When a transient voltage event occurs, the Zener diode “breaks down” and diverts the current to ground. This process is known as “clamping” and is what protects the circuit from damage due to the transient voltage event. The diode’s breakdown voltage, or clamping voltage, is determined by the type and size of the Zener diode used in the device. The higher the clamping voltage, the more effective the protection provided by the device.

The B72590T7050S160 provides superior protection due to its high rated voltage of 160Vdc and high capacitance of 70pF. The device is also able to handle up to 80mA of peak pulse current without damage, making it ideal for use in applications that require a high degree of transient voltage protection.
