TVS (Transient Voltage Suppressor) is one of the most popular and widely used components in the electronics industry. As such, it has a variety of application fields and working principles across modern electronics. In this article, we will discuss the application field and working principle of the VE17P01750K particular TVS in detail.

VE17P01750K TVS is broadly categorised as a medium voltage radially leaded device, typically designed for transient suppression. It features a reverse standoff voltage of 17VDC and a maximum reverse clamping voltage (9/1000 microseconds pulse) of 950V. Its surge capability (8/20 micro seconds) is up to 50kA (8/20µs) at 600W peak pulse. It has an operating temperature range of -65°C to +150°C, making it suitable for even the harshest of conditions.

The main application of VE17P01750K TVS is as transient suppression device. It is mainly used in various power circuits to protect the system against transient voltage events. These type of events could be caused by a variety of sources such as motor start-up/shutdown, load switching, etc. The VE17P01750K provides excellent protection against these events and safeguards the overall system. It can also be used in a variety of automotive systems (including automotive equipment and injection systems) and consumer appliances where robust protection is required.

The working principle behind the VE17P01750K is based on the avalanche effect. This phenomenon occurs when a voltage threshold is exceeded by an applied voltage, either a DC or an AC voltage. When the voltage exceeds the particular threshold, the transistor or TVS starts to conduct a larger current, which reduces the voltage to prevent damage to the device. This is known as a back-to-back avalanche breakdown and is the key behind transient protection. The VE17P01750K can withstand high-energy transients and is designed to divert the energy away from the protected equipment.

In summary, the VE17P01750K stationary device is mainly used in applications where transient protection is desired. Its working principle is based on the avalanche breakdown, where the circuit is protected against high energy transients and the voltage is limited to a safe threshold. It features a reverse clamping voltage and is suitable for a variety of applications in harsh conditions. Overall, it is an excellent device for protecting sensitive electronic equipment against transient voltage events.
