TVS (transient voltage suppressors) diodes are widely used in circuit protection due to their fast response. SM8S16AHE3/2D from Littelfuse is a TVS diode that can protect circuits from high-energy transients (HETs) or high-voltage spikes, such as those caused by lightning or from switching inductive loads. The SM8S16AHE3/2D also known as the "Glacier" TVS diode is suitable for a variety of applications, including automotive, industrial, and medical applications. The device features 8V operating voltage, 16A surge capability, and low leakage current.

The most common use for the SM8S16AHE3/2D is to protect electronic circuits from voltage spikes. TVS diodes absorb transients caused by outside disturbances, such as lightning or electromagnetic interference, by clamping the voltage to a safe level. This protects sensitive electronics from damage, reduces the risk of component failure and minimizes downtime. The SM8S16AHE3/2D has a rated breakdown voltage of 8V and a unidirectional clamping voltage of 10.5V for positive transients. This means that any voltage spike greater than 8V will be clamped at 10.5V, which is below the breakdown voltage of many integrated circuits and other sensitive components.

In addition to voltage protection, the SM8S16AHE3/2D provides current protection. The device has a peak surge capability of 16A, and an 8/20us waveform that can protect against high-energy transients. The device also has a low leakage current of 3µA, which helps protect against high-frequency transients. This makes the device suitable for a variety of applications, including automotive and industrial applications, as well as medical devices.

The SM8S16AHE3/2D is a Zener diode-style TVS diode. It works by clamping the voltage to a safe level, and for this reason it is often referred to as a clamping diode. When the device is exposed to a voltage spike, the diode absorbs the energy and shunts it to ground. This prevents the voltage from rising above a certain level, protecting sensitive electronics from damage.

The SM8S16AHE3/2D is a robust and reliable device for protecting sensitive electronics from voltage transients. It offers 8V operating voltage, 16A surge capability, low leakage current, and its 8/20us waveform can protect against high-energy transients. The device is suitable for a wide range of applications, including automotive, industrial, and medical applications.
