TVS diodes, or transient voltage suppressors, are specially designed electronic components capable of protecting other circuit components from transient voltage conditions. Specifically, the SA100HE3/73 is a bi-directional silicon transient voltage suppressor whose key feature is its ability to protect circuits from voltage spikes of up to 500W peak pulse power. It is well suited for a variety of applications, primarily those that require additional reliability, robustness, and longevity.

The SA100HE3/73 provides surge current capability at low power levels; in addition, the device has a low clamping voltage and a tight clamping window, resulting in excellent transient protection.

The SA100HE3/73 is also designed to handle typical operating conditions. The device has a peak reverse voltage (VRWM) of 15V and a peak pulse power rating of 500 W. The maximum clamp current is 1 A, and the device can operate between temperatures of-55°C to 150°C. Additionally, the device has a fast response time, typically only 72 ns from the time a transient voltage is detected, resulting in excellent transient protection.

The SA100HE3/73 is a versatile impulse voltage suppressor that can be used in a variety of applications, such as power supply modules, telecom systems, DC/DC converters, automotive, and other high-voltage applications. The devices can also be used in DC circuits for 12V protection, as well as other high-frequency applications where only low power signals are present.

The working principle of the SA100HE3/73 device is as follows: when the external surge voltage at the outer terminals is greater than the breakdown voltage of the device, a large current will flow through the device, which will cause the protection to begin. When the surge current exceeds the device’s maximum limit, the device will begin to reduce the current and start to clamp the voltage. The device will regulate the surge current as it decreases until the voltage returns back to the operating voltage.

The SA100HE3/73 provides an efficient and reliable solution for protection in a wide range of applications, including transient voltage applications in power supply modules, automotive, telecom systems, DC/DC converters, and high-frequency applications. The device\'s low clamping voltage and wide operating range make it an ideal choice for systems that require robust transient protection.
