Transient-Voltage-Suppression (TVS) diodes are special purpose silicon integrated-circuit (IC) protection components used in many different applications. SM5S36A-E3/2D is one such TVS diode featuring Electrostatic Discharge (ESD) protection. This TVS diode applications include industrial, battery systems, and consumer devices.

The SM5S36A-E3/2D has a low leakage current standby mode, with an operating voltage of 5 to 36 V, maximum reverse leakage current of 1 us maximum at 5 V, and a maximum clamping voltage of 5 V. The package size, or footprint, of the SM5S36A-E3/2D is relatively small at a length of 3.30 mm, a width of 3.05 mm, and a height of 1.80 mm, making it suitable for applications with limited space. As an additional feature, the SM5S36A-E3/2D is RoHS compliant.

The SM5S36A-E3/2D provides ESD protection up to 30 kV contact and air discharge according to the IEC 61000-4-2 standard, as certified by independent laboratories. This protection can be used for end-product ESD and electrostatic overshoot protection. It protects critical components from damage caused by high transient voltages, thereby preventing any kind of damage to device or system equipment.

The operating principle of the SM5S36A-E3/2D is relatively straightforward. The device is basically a reverse biased diode that is connected between a power line and ground. When a surge in voltage occurs, the diode switches on and begins conducting current. During this process, the energy absorbed by the device is dissipated in the form of heat. This structure of the device also enables the device to serve as an ESD protection diode.

In addition to its ESD protection capabilities, SM5S36A-E3/2D can also be used for applications such as inductor-less datalines, Ethernet ports, DC-DC converters, and protection of high-speed signals. As it is a surface-mount component, SM5S36A-E3/2D can also be used for high-density printed circuit board (PCB) designs.

By providing ESD protection for up to 30 kV contact and air discharge, the SM5S36A-E3/2D helps to prevent damage to systems and components. It provides protection in applications such as inductor-less datalines, Ethernet ports, DC-DC converters, protection of high-speed signals, industrial, battery systems, and consumer device use, as well as high-density PCB designs. As it is RoHS compliant, it can be used with confidence in applications that require stringent environmental regulations. Moreover, its small size makes it an ideal choice for applications with limited space.
