1SMB70AT3

Transient Voltage Suppressor diodes (TVS diodes) are a combination of an avalanche diode and a clamping diode. TVS diodes are designed to protect sensitive electrical systems from voltage transients caused by electrical overstress (EOS). The 1SMB70AT3 is one such TVS diode that is commonly used in various applications.

The 1SMB70AT3 is an unidirectional diode that is packaged in a low-profile SMA surface mount package with a very small footprint to save board space. It is designed for use in applications ranging from 50V to 1300V and has an operating temperature range from -55°C to 175°C. Additionally, it features a low-clamping voltage of 75V, a low forward voltage drop of 0.6V, and an operating current of 200mA. This makes it ideal for use in high-frequency consumer electronics, such as cell phones, notebook computers, and audio receivers.

The 1SMB70AT3 works by clamping voltage transients to a relatively low level. This allows the device to absorb transient energy without sacrificing circuit performance, which is a common fault of other voltage protection devices. The diode is usually connected in parallel to a device or circuit that needs protection against over-voltage so that when a transient voltage arises, the diode will conduct current and clamp the voltage level. This protects both the device or circuit and any components that are downstream.

The 1SMB70AT3 is able to quickly respond to and protect from voltage transients and yet maintain low levels of parasitic capacitance. This makes it ideal for use in high-speed and low-noise applications. Additionally, the diode\'s integrated terminals make it ideal for reflow soldering to the board and it has a robust standard tape and reel packaging that offers improved board-level performance in automated assembly.

Overall, the 1SMB70AT3 transient voltage suppressor (TVS) diode is an essential part of any electrical system that needs to be protected from voltage transients. Its low-clamping voltage of 75V, low forward voltage drop of 0.6V, wide operating temperature range and low parasitic capacitance make it ideal for high-speed, low-noise applications. The 1SMB70AT3 is available in the SMA package and standard tape & reel packaging. This makes it perfect for automated assembly and easy reflow soldering to the board.
