1SMA22AT3G Description

Short technical summary and product information.

The 1SMA22AT3G is a unidirectional TVS diode manufactured by Littelfuse Inc. It is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge. The device features a reverse standoff voltage of 22V and a clamping voltage of 35.5V, ensuring that downstream components are not exposed to damaging overvoltage conditions.

 

With a peak pulse power dissipation of 400W and a peak pulse current capability of 11.3A, this diode provides robust transient protection for general-purpose applications. The operating temperature range spans from -65°C to 150°C, allowing reliable performance in harsh environments.

 

The 1SMA22AT3G is housed in a DO-214AC (SMA) surface-mount package, making it suitable for automated assembly processes. It is RoHS3 compliant and has an MSL rating of 1 (unlimited), simplifying handling and storage requirements. This component is ideal for use in power supplies, industrial controls, and consumer electronics where space-constrained board layouts demand compact protection solutions.
