TVS (Transient Voltage Suppressor) Diodes are used for lightning and surge protection in electronics. The 5KP45E3/TR13, specifically, is designed for line-to-ground overvoltages protection and is suitable for applications like embedded industrial and telecom/datacom power supplies, as well as chargers and adapters. Its low clamping voltage makes it ideal for protecting consumer and industrial products against overvoltage transients.

The 5KP45E3/TR13 consists of two elements - a thyristor and a diode - that work together to protect the system from overvoltage transients. When the thyristor is triggered, it triggers the diode, which limits the voltage on the protected line to clamping voltage. This mechanism is explained in more detail below.

Application Field

The 5KP45E3/TR13 is suitable for protecting industrial, telecom/datacom, consumer and automotive electronics and microprocessors. Specifically, the 5KP45E3/TR13 is designed for protecting a variety of embedded industrial and telecom/datacom power supplies, including chargers, adapters, supplies and other applications. The 5KP45E3/TR13 is also suitable for applications such as TV receivers, HD receivers, set-top boxes, broadcast receivers, cellular phones, interface buses, etc. This diode is designed to protect equipment against overvoltage transients. It is especially well suited for protecting equipment from lightning surges.

Working Principle

The 5KP45E3/TR13 is made up of two elements - a thyristor and a diode - that work together to protect the system from overvoltage transients. The thyristor is triggered when the voltage on the input line rises above a certain level (the trigger voltage). The thyristor then turns on and the voltage on the input line is clamped to the clamping voltage. In this state, current flows both ways through the thyristor, allowing any remaining overvoltage transient to be dissipated safely.

The diode acts as a short circuit, preventing any further voltage increase on the input line. This limits the voltage on the protected line to the clamping voltage, thus protecting the system from overvoltage transients. The current then flows in the opposite direction through the diode, which prevents any further voltage rise. The thyristor then turns off, returning the system to its normal state.

The 5KP45E3/TR13 is designed to dissipate both thermal and overvoltage energy. The low clamping voltage makes it ideal for protecting consumer and industrial products against overvoltage transients. This diode is engineered with excellent surge current capability, fast transient response and superior clamping performance.

In conclusion, the 5KP45E3/TR13 is a robust TVS diode that is designed for protecting industrial, telecom/datacom, consumer and automotive electronics and microprocessors against transient voltages. It is equipped with two elements - a thyristor and a diode - that work together to limit the voltage on the protected line to clamping voltage and dissipate any remaining overvoltage transients.
