Transient Voltage Suppressors (TVS) diodes are widely used in circuit protection as they provide an efficient and cost-effective way to protect electronic components from voltage spikes. The SA43HE3/54 TVS diode is a cost-effective device that offers robust overvoltage protection against a wide range of power line transients.

The SA43HE3/54 TVS diode is a two-terminal unidirectional device that is designed to protect sensitive electronics from voltage spikes by clamping the voltage. It is rated at a peak pulse power of 400W and a peak surge current of 1.5kA. The device can be used in applications ranging from power lines to communication systems, and is especially useful in lightning protection applications.

The SA43HE3/54 TVS diode is constructed using a proprietary silicon chip technology, which helps to protect its sensitive components against damage caused by voltage spikes. The device has a high-voltage capacity and can easily absorb high-voltage spikes up to 400V. It also has a fast response time and can absorb the voltage spikes within nanoseconds.

The SA43HE3/54 TVS diode uses a Zener diode to start the clamping action. The Zener diode is connected in series with a Transient Voltage Suppressor (TVS) diode. When the voltage exceeds the breakdown voltage of the Zener diode, the TVS diode starts to clamp the voltage. The voltage is then clamped to the clamp voltage of the TVS diode. This clamping action is what makes the device so effective at protecting sensitive electronic components from harmful voltage spikes.

The SA43HE3/54 TVS diode is designed for use in a variety of applications, including power line protection, lightning protection, and communication systems. It is also suitable for use in a number of other systems that require voltage protection. The device is relatively inexpensive and is easy to install and maintain. The device has a RoHS-compliant package and is also available with an optional mounting clip.

Overall, the SA43HE3/54 TVS diode is an efficient and cost-effective device that offers robust overvoltage protection. It can be used in a variety of applications and is relatively easy to install and maintain. Its Zener diode-TVS diode combination provides fast response times and can easily absorb high-voltage spikes.
