TVS (Transient Voltage Suppressor) Diodes are a type of semiconductor component that is designed to handle variations in voltage that occur during normal operation of electrical equipment, and protect such equipment from damage due to abnormal changes in voltage. The SA24CAHE3/54 is a range of relatively cost effective and often space-saving unidirectional TVS Diodes, capable of withstanding transients up to two thousand Volts ([V]) and suppressing transients from 200V to 1000V. It is used for direct ‘Automotive grade’ protection for plastic, ceramic, and printed circuit boards.

SA24CAHE3/54 TVS Diodes work by means of a very simple principle – they have the ability to attenuate transient voltage surges via a high-speed clamping operation. The diode is designed to only conduct current in one direction, meaning that excess current is redirected to ground through the use of a zener diode, avalanche breakdown zone, and a snap-back region. When an overvoltage is detected, the breakdown zone and snap-back region kick in to ensure that only a limited amount of current passes through the diode. This form of voltage clamping will limit the amount of current in an electrical circuit to an acceptable level and protect the equipment from damage.

SA24CAHE3/54 TVS Diodes are suitable for use in a wide range of applications, including automotive electronics, consumer electronics, industrial electronics, telecommunication systems, and medical equipment. They are often used for levels of protection that require tolerance to transients up to two thousand volts. Their purpose is to reduce the possibility of damage from electrostatic discharges, lightning strikes, and other voltage transients.

The SA24CAHE3/54 range of TVS Diodes are available in two operating voltage ranges of 4.53V or 8.35V. They are available in SOT-23 or SOT-323 packages, making them ideal for use in space-constrained applications. They are also renowned for their superior surge capability, with the ability to survive transients up to two thousand volts and reverse leakage current of at most one hundred nanoamperes ([nA]). The typical capacitance of these diodes is only one to three picofarads ([pF]).

With its wide range of features and electrical specifications, the SA24CAHE3/54 TVS Diode is an ideal protection solution for many types of sensitive equipment. Its ease of use and space-saving design make it an excellent choice for those looking for an affordable and reliable surge protection option.
