TVS (Transient Voltage Suppressor) diodes are semiconductor devices designed to protect vulnerable electronics from voltage transients caused by electrostatic discharge (ESD), electrical overstress (EOS) or lightning. At SMC, the SM8S24AHE3_A/I is a bi-directional TVS diode that is specifically designed to protect I/O ports of modern portable electronic equipment against overvoltage transients. It is ideal for use in the latest generations of handheld devices, such as digital audio players and personal digital assistants.

The SM8S24AHE3_A/I TVS diode consists of silicon avalanche junction diodes that are designed to protect sensitive microelectronics from damage caused by overvoltage transients. It is designed so that it can provide robust protection from high-energy attacks. It can protect against a surge of up to 18V with a breakdown voltage of 17V. It can handle currents ranging from several hundred nanoamps to several hundred milliamps, depending on the transient energy. The rated peak pulse power is 8 watts.

The SM8S24AHE3_A/I TVS diode is available in a small SOD-122 package, making it suitable for use in very small or tightly packed electronic devices, including cell phones and modems. It is lead-free and RoHS compliant.

The basic working principle of the SM8S24AHE3_A/I TVS diode is simple. When a transient voltage of sufficient magnitude appears across the devices terminals, it is clamped to a maximum voltage level at the specified breakdown voltage. This limits the voltage across the protected device and prevents it from being damaged by the high voltage.

The SM8S24AHE3_A/I TVS diode has many advantages over traditional protection devices. It is smaller, cheaper and more efficient than traditional overvoltage protection devices. It is also faster at responding to transient voltage spikes and more robust against high-energy transients. Additionally, it requires less board space for installation and can be used for multiple applications.

The SM8S24AHE3_A/I TVS diode is a reliable and cost-effective option for modern portable electronic equipment. With its increased size and high efficiency, it is an ideal choice for protecting I/O ports against transient voltage spikes.
