Transient Voltage Suppressor (TVS) diodes, Metal-Oxide Varistors (MOVs) and other lateral devices provide effective protection for the complete system against lightning and electrical transients and interference.

The B72220T2231K101 transient voltage suppressor is a bi-directional surge protection device that can be used in a wide variety of applications from alternate or DC power systems to lighting control. It is designed for effective protection against transients and overvoltage in personal electronic consumption goods and telecommunications equipment.

The B72220T2231K101 provides surge protection for printed circuit boards, data transmitters, small electronic controllers, GSM/GPRS receivers and transceivers, outdoor antennas, as well as other small consumer devices. Its bidirectional, low-capacitance technology also makes it suitable for use in automotive and industrial applications.

The B72220T2231K101 has a low capacitance of 0.25 pF between the two pins and a high peak surge current of 2200A (8/20 µs). The device is designed to withstand a repetitive peak power of greater than 1500W. It also has a low reverse leakage current and high peak surge current capability with excellent bandwidth characteristics from transient events.

The B72220T2231K101 can be applied across a DC or AC line to provide protection against transients and overvoltages. When an overvoltage condition occurs, the B72220T2231K101 acts as a clamping mechanism to divert the excess voltage away from the protected device. When normal voltage return, the device stops clamping and returns to its normal state.

In addition to providing protection against transients and overvoltages, the B72220T2231K101 also functions as a temperature-dependent surge limiter. In applications where space is at a premium, the device can also be used as a low-noise alternative to MOVs. The device has an operating temperature range of -55ºC to 125ºC, making it suitable for industrial and automotive applications.

The B72220T2231K101 is UL recognized and compliant with current RoHS regulations. Its exceptionally high surge response makes it well suited for use in a wide variety of applications, from general consumer goods and industrial applications to automotive electronics. The device is easy to install and requires minimal circuit board space, making it the ideal choice for protecting sensitive electronic components against transient and overvoltage events.
