TVS diodes, also known as Transient Voltage Suppressors, are electrical components designed to protect external circuits from high voltage surges. As the name suggests, they are designed to temporarily suppress overvoltage events by clamping the voltage and limiting the current just as fuses do, without breaking the circuit. 5KP20AE3/TR13 is a diode array device, consisting of four separate diodes, that is designed to protect sensitive electronic components from electrostatic discharges (ESDs) and other electrical threats, such as lightning.

Applications

5KP20AE3/TR13 diode array can be used in a variety of electronic devices, mainly in those designed to work in harsh electromagnetic environment. As a result, it is suitable for a wide range of applications, from portable electronic devices to aerospace and automotive systems. Some of the most frequent applications include:

• Protection of sensitive electronic components, such as integrated circuits and microcontrollers from ESDs, electrical overvoltage and other electrical transients.
• Lightning protection for aircrafts, helicopters and other aircrafts.
• Protection of electronic components in automotive applications.
• Lightning protection for military and industrial systems.

Working Principle

The 5KP20AE3/TR13 is a diode array component, and as such its working principle is based on the behavior of standard diodes. When a high voltage is applied to the diode, the diode becomes forward biased, and the majority of the current flows through its body. The diode array protects the system by claming the voltage, limiting its peaks, and dissipating it in the form of transient current pulses. This keeps the voltage within the limits of the device\'s robustness, and prevents any damage.

The diode array has a breakdown voltage of 5.3 kV for unidirectional transients, and 3.75 kV for bidirectional transients. This is typically enough for most applications, and helps to protect the device from electrical overvoltage and other hazardous surges. Additionally, the device is rated for up to 1.2A of maximum peak current and a clamping voltage of less than 15V.

Conclusion

5KP20AE3/TR13 is a diode array device, designed to protect sensitive electronic components from ESDs, electrical overvoltage, and other electrical transients. As such it is suitable for a wide range of applications in both consumer and industrial electronics, aircrafts, helicopters, and automotive systems. The working principle of the device is based on the standard diode behavior, and thus it is able to temporarily suppress overvoltage events and limit the current.
