     SM5S24AHE3/2D is one of the most popular TVS-Diodes products. It is a unidirectional transient-voltage protection device in a standard 5SOD-123 package with a space-saving profile. This device is designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events.This device is commonly used to protect power lines in automotive applications, datacom and telecom equipment, machines, and industrial instruments. It has the features needed for high-efficiency voltage transient protection, such as low clamping voltage, fast (less than 1ns) response time, low capacitive switching elements, and a wide operating temperature range.Working PrincipleThe SM5S24AHE3/2D device is designed to protect sensitive electronic equipment from voltage transients caused by electrical disturbances, such as those induced by lightning strikes or other transient voltage events. The device works by clamping the input voltage to a safe level that will not damage sensitive components.The SM5S24AHE3/2D is designed with a fast-acting Zener Diode that is connected to the input power supply. When a transient voltage occurs, the Zener Diode begins to conduct current, lowering the voltage on the power supply. The voltage is then limited to a safe voltage level, usually 15V, by a series of metal-oxide varistors (MOVs) connected across the diode. The MOVs absorb the excess energy, preventing it from reaching the circuits and protecting them from damage. ConclusionThe SM5S24AHE3/2D is one of the most popular TVS-Diodes devices and is designed to provide unidirectional protection from voltage transients. It is most commonly used in automotive applications, datacom and telecom equipment, machines, and industrial instruments. Its fast-acting Zener Diode combined with series of metal-oxide varistors efficiently clamps the input voltage to a safe level, protecting sensitive components from damage.
