A Transient Voltage Suppressor (TVS) is a device designed for the protection of electrical systems from voltage surges above normal system voltage levels. The most common type of TVS is the diode-based TVS, which also includes the 15KPA20AE3/TR13. This device is a diode designed for use in applications requiring low clamping voltage, high surge capability and low capacitance.

The 15KPA20AE3/TR13 is a unidirectional diode that protects against ac/dc transients when placed across power supply lines or individual IC circuits. It features a low-clamping voltage of 13V and high surge capability of 20A. The device is available in an ultra-small SOD-323FL package and is ideal for space-constrained applications such as automotive, avionics and test and measurement equipment.

Working Principle of 15KPA20AE3/TR13

The working principle of the 15KPA20AE3/TR13 is based on two main processes. The first process is called breakdown. This is when the device\'s reverse bias voltage reaches the breakdown voltage (Vb), at which point the device\'s current increases exponentially. The second process is called clamping. This is when the current reaches the peak rating (IP) of the device, at which point it reduces to a steady-state current which is determined by the device\'s clamping voltage. This is also known as the device\'s zener voltage.

The 15KPA20AE3/TR13 has a breakdown voltage of 5 V and a zener voltage of 13 V. When reverse biased, a voltage of 5 V or higher applied across the device will cause a current to flow through it, causing it to breakdown. At this point, the device\'s current will start to increase exponentially. When this current reaches the peak rating of 20 A, the device will go into clamping mode, reducing the current to a steady-state level determined by its zener voltage of 13V. This current can be as high as 20A.

Applications of 15KPA20AE3/TR13

The 15KPA20AE3/TR13 is suitable for applications requiring low clamping voltage, high surge capability and low capacitance. It is widely used in automotive, avionics, test and measurement equipment, computers and peripherals, communications equipment, consumer electronics, and industrial control systems. Other common applications include power supplies, signal conditioning networks, EMI protection, ESD protection, and RFID applications.

In automotive, for example, the 15KPA20AE3/TR13 is used to protect automotive systems from voltage surges due to EMI, ESD, or other environmental factors. In avionics, it is used to provide surge and ESD protection for sensitive navigation and control systems. In industrial control systems, it is used to protect circuits from power surges due to power line transients. The device also has a variety of other applications such as in consumer electronics, computers and peripherals, and communications equipment.

Conclusion

In conclusion, the 15KPA20AE3/TR13 is a diode-based transient voltage suppression device that offers low clamping voltage, high surge capability, and low capacitance. It is suitable for a range of applications, including automotive, avionics, test and measurement equipment, computers and peripherals, communications equipment, consumer electronics, and industrial control systems. The device provides protection against EMI, ESD, and power line transients across power supply lines or individual IC circuits.
