SPHV36-01ETG-C

TVS - Diodes are widely used in applications such as audio, video, automotive, and communication technology. They protect against damage due to electrical overloads, such as lightning and other power surges, and as such, they are an essential part of many electrical systems. The SPHV36-01ETG-C is a popular TVS - Diode that is suitable for a wide range of applications. This article will explore the application field and working principle of the SPHV36-01ETG-C.

The SPHV36-01ETG-C is a unidirectional transient voltage suppressor with a wide operating temperature range of -55 to 125°C. It features low leakage current, fast response time and low static capacitance. Its low capacitance of 305pF makes it suitable for high frequency applications, such as various types of automotive electronics and communications devices. It is also suitable for applications requiring resistance against voltage spikes up to 36V.

The SPHV36-01ETG-C is designed to provide protection against voltage surges in automotive, consumer electronics and communication applications. It can be used to protect against voltage spikes due to lightning, power surges, and other transient events. In addition, it is also suitable for reverse polarity protection in application where the polarity of the supply voltage can change.

The working principle of the SPHV36-01ETG-C is based on the use of a voltage-sensitive gain medium. When a voltage spike or transient event occurs, the gain medium will respond instantly, shutting off or diverting the electrical current and preventing it from damaging the system. This is achieved through the use of avalanche, or "snapback" diodes. These diodes limit the spread of any surges, but several layers of protection are typically incorporated into the circuit design to ensure effective protection.

When a voltage exceed the peak reverse voltage (PRV) rating, the gain medium reacts quickly, leading to avalanche breakdown. This avalanche breakdown shunts the incoming excess voltage, leading to a rapid decline in the voltage across the device. As a result, the voltage across the load is limited to the breakdown voltage rating. This protects the system from damage, even when the incoming voltage exceeds the breakdown voltage.

The SPHV36-01ETG-C is designed for quick reaction to transient events, and its discharge time is less than one microsecond. This makes it suitable for a range of automotive, consumer electronics and communication applications that require fast response and reliable protection. Its wide operating temperature range makes it suitable for use in extreme temperature environments as well.

In summary, the SPHV36-01ETG-C is a popular and reliable transient voltage suppressor that is suitable for automotive, consumer electronics, and communication applications. It is designed to provide fast response and reliable protection against voltage surges, and its wide operating temperature range makes it suitable for a wide range of applications.
