SM5S17ATHE3/I Circuit Protection

SM5S17ATHE3/I is a TVS – Diode having Axial Lead and Glass-passivated body. It is designed to protect multiple lines such as USB, HDMI, networking, telecom and automotive applications against transients caused by electrostatic discharge (ESD) and electro-conductive particles. This device is capable of handling up to 17A peak pulse current and provides high level of protection against high energy transients.

In terms of applications, the SM5S17ATHE3/I is mainly used in circuit protection where it can protect against electrostatic discharge, electro-conductive particles, and high energy transients. The SM5S17ATHE3/I\'s cost-effective design with axial lead and glass-passivated body makes it most suitable for consumer electronics, gaming, automotive and industrial applications, just to name a few.

In terms of working principle, the SM5S17ATHE3/I integrates two different mechanisms for protection. The first is an electrostatic discharge mechanism, which is a fast-acting ESD protection. This mechanism is used to protect against sudden static discharges and is triggered by electrostatic potentials of up to 8kV on the I/O pin.

The second protection mechanism is a self-protection mechanism that provides longer-term protection. This mechanism is activated when a high-current glitch occurs on the I/O lines. The protection kicks in and limits the current flow to a safe level, reducing the risk of damage to the device.

The SM5S17ATHE3/I is also designed for reverse-bias standoff capabilities. This means that it can effectively suppress transients generated from mis-wiring and reverse polarity protection. It also features an ultra-low leakage current so that the power loss in the device is minimized.

In summary, the SM5S17ATHE3/I is a cost-effective and reliable device that is suitable for multiple lines such as USB, HDMI, networking, telecom and automotive applications. It integrates two different types of protection mechanisms – ESD and self-protection – and has reverse-bias standoff and low leakage current capabilities. It is the most suitable choice in terms of value, performance, and reliability for a variety of applications.
