Transient Voltage Suppressors (TVSs) are semiconductor devices used to protect electrical systems from transient overvoltages caused by electrostatic discharges (ESD), electrical fast transients (EFT) and surge events. The TVS diode, also known as a protector, is the most common type of TVS device, designed for bidirectional protection, meaning it blocks both positive and negative transient voltages.

The 15KPA280ATR is a diode designed to protect against transient overvoltages that exceeds the required breakdown voltage, also known as the clamping or protection voltage. It allows normal levels of static current, up to 5amps, to pass through, but effectively blocks higher levels. The device has a breakdown voltage of 28 volts, a low working voltage of 6 volts, and is capable of passing up to 5 amps of continuous current.

The 15KPA280ATR’s application field includes telecomms, industrial control, consumer electronics and automotive electronics. It can provide very effective protection capability for circuits which need to meet stringent regulatory requirements, while being immune to false triggering due to EMI/EMC.

The 15KPA280ATR is designed for bidirectional protection, which means it offers the same level of protection regardless of the polarity of the transient voltage. The device works by clamping or limiting the voltage to its lower breakdown voltage. The lower breakdown voltage is achieved through a combination of semiconductor junctions and resistance in the structure. The resistance creates a slight voltage drop, which helps to reduce the peak voltage, while the semiconductor junction provides the majority of the voltage drop, resulting in a significantly reduced peak voltage.

Using TVS devices such as the 15KPA280ATR helps to protect electronics from damaging transient voltage surges. The device works by clamping the voltage to its breakdown voltage, thus limiting the voltage to a safe level. This prevents the circuit from suffering damage due to overvoltage. The device has a low working voltage and can handle up to 5 amps of continuous current, which makes it suitable for various applications in telecomms, industrial control, consumer electronics and automotive electronics.
