1.5KE20AE3/TR13

TVS diodes, or transient voltage suppression diodes, are an important component for the safeguarding of electrical circuits from damaging voltage transients. The 1.5KE20AE3/TR13 is one example of a TVS diode aimed at providing surge protection for a connected device. This guide will cover the general application field of the 1.5KE20AE3/TR13, as well as its working principle.

Application Field

The 1.5KE20AE3/TR13 is designed to protect circuits from overvoltage transients originating from lightning strikes and other sources. It is typically used in AC power lines, interfaces, computer peripheral cards, and long wave data systems. The 1.5KE20AE3/TR13 can also be used in applications where an on-chip surge-suppression diode is not needed.

Working Principle

TVS diodes like the 1.5KE20AE3/TR13 are made up of two components: a voltage-variable, semi-conductor diode and a shunt breakdown. The diode is designed to limit the voltage surge by clamping the voltage and preventing the voltage from rising above a specific level. The shunt breakdown also helps to limit the voltage surge by providing an alternate path for current to flow, relieving the voltage stress. When a voltage surge is detected, the TVS diode will activate, limiting the voltage at a safe level.

Conclusion

The 1.5KE20AE3/TR13 is an important component for any electronic device that needs protection from overvoltage transients such as lightning strikes. This TVS diode is capable of limiting the voltage surge in order to protect the connected device. Its application field includes AC power lines, interfaces, and more, providing much-needed surge protection.
