Transient voltage suppressors, also known as TVS diodes, are used for the protection of systems subjected to potentially large voltage transients (spikes). A common example of this is the protection of sensitive electronics from damage that can occur when several leads of power cables are disconnected. The SA15HE3/73 TVS diode is a zener diode with a standoff voltage of 15V and a break down current of 720mA.

The construction of the SA15HE3/73 includes a junction between p-type and n-type material in the same way as a conventional diode. The addition of an n-type area in the p-type material adds an extra area of charge build-up and prevents normal breakdown. This is the basis of TVS diodes, which can absorb much higher transients of energy than conventional diodes at no risk to the electrical equipment.

The SA15HE3/73 is an unidirectional TVS diode, meaning that it can only conduct when current is applied in one direction. The device can protect sensitive equipment from transients exceeding the diode\'s forward voltage, which is 15V (maximum). Any voltage over this will cause the element to conduct and reduce the supply voltage until it returns to normal. The device is designed to dissipate up to 7.2W and can handle pulse currents up to 720mA.

The SA15HE3/73 has a wide range of applications where it can prove valuable in protecting electronics from transient over-voltage damage. These include automotive applications, industrial equipment, LED lighting systems, medical devices and other systems where large voltage spikes could damage the circuit or devices. The device can also be used to dissipate and regulate the voltage during system start-up, preventing large over-voltage transients.

The SA15HE3/73 is a reliable and cost-effective device that is perfect for protecting sensitive electronic systems from damage caused by over-voltage transients. The device is easy to install and requires minimal maintenance, making it an ideal solution for applications where reliable protection is critical. The device is also RoHS-compliant, making it suitable for many different applications and environments.
