5KP18

TVS-Diodes

Transient Voltage Suppressor (TVS) diodes, also known as surge-protective diodes, are widely used in a variety of electronic circuits. In these circuits, the diodes act as a switch that open and close during over-voltage conditions, thereby protecting components from electrical over-voltage or short circuits. The 5KP18, specifically, is a popular TVS diode used to protect systems against electromagnetic interference in industries dealing with transportation, communications and consumer electronics.

Application Field of 5KP18

• Circuits with low capacitance.
• Wireless charging platforms.
• Electronics used in harsh weather conditions.
• Power management and control circuitry.
• Data transmission and receiving circuitry.

The 5KP18 device is typically used in automotive systems to protect wiring against short circuits and over-voltage conditions. This is important in situations where the system is exposed to impact, vibration, and water, as it helps protect the system against any short-term overvoltage events that may occur.

Working Principle of 5KP18

The 5KP18 device is a zener diode with a reverse breakdown voltage rating of 18 volts. When the voltage rating is exceeded, the diode will open, and current will stop flowing through it. This helps to protect the circuit from short circuits and over-voltage surges.

In addition to using the 5KP18 as a switch, it can also function as a voltage regulator. When voltage in the circuit drops below its threshold, the diode will close and current will begin to flow. This helps to maintain a stable voltage across the circuit.

In applications such as automotive use, the 5KP18 can help protect against electrical interference by limiting the current passing through it during an over-voltage event. This can help to prevent interference from adversely affecting the performance of the system.
