5KP18AE3/TR13

Transient Voltage Suppressor (TVS) diodes are widely used in all sorts of applications that require protection from voltage transients. The 5KP18AE3/TR13 is one such device used primarily for Automotive Electronics applications, though it can be used for a variety of other applications.

The 5KP18AE3/TR13 is a bi-directional/bidirectional TVS diode that is composed of two diodes connected in a series array to form a so-called avalanche effect. It is used to protect systems from a variety of transient voltage conditions such as transient electrical noise, over-voltage surges, electrostatic discharge (ESD), and other types of electrical transients. It can prevent damage to sensitive electronic components as it diverts large transient currents away from them.

The 5KP18AE3/TR13 has an operating voltage of 18 Volts and a reverse stand-off voltage of 12 Volts, making it an ideal choice for protecting automotive electronics, such as ECU’s, and other systems in vehicles. It has a voltage rating of 5 Kilovolts (KV) and a power rating of 18 Watts, making it more than capable of handling typical spike surges up to 4 Kilovolts and 250 Amps.

The structure of the 5KP18AE3/TR13 consists of two silicon diodes embedded in a single package. This design provides a higher level of pulse protection and surge protection in comparison to standard diode structures. The 5KP18AE3/TR13 also features a wide tolerance of clamping voltage, allowing it to provide greater protection over a wide range of transient voltage conditions.

In terms of working principle, the 5KP18AE3/TR13 operates by having two stacked diodes that have a different breakdown voltage. When a transient voltage surge occurs, the forward-biased diode transitions to a reverse-biased state, forming an avalanche effect. This creates a low-resistance pathway, which causes the voltage to be “clamped” at the breakdown voltage of the reverse-biased diode. This reduces the amount of current that passes through, thus preventing damage to sensitive electronic components.

The 5KP18AE3/TR13 is a great choice for protecting a wide range of automotive electronics and systems, thanks to its high breakdown voltage rating, fast response time, and wide tolerance of clamping voltage. It is also useful in industrial and consumer electronics applications due to its low leakage current and high reliability. Furthermore, the 5KP18AE3/TR13 has a high surge rating, allowing it to provide greater protection against high voltage and current transients.

In conclusion, the 5KP18AE3/TR13 is an ideal choice for applications requiring protection from voltage transients. It offers fast response times, wide voltage clamping tolerance, high surge and power ratings, and is suitable for use in automotive electronics, industrial electronics, and consumer electronics.
