Overview of SMAJ12A by Littelfuse Inc.
The SMAJ12A is a transient voltage suppressor (TVS) diode, rated for 400W and designed to protect sensitive electronics from voltage spikes and surges by clamping excess voltage to a safe level. It has a reverse standoff voltage of 12V, with a maximum clamping voltage of 19.9V when subjected to a peak pulse current. This component is unidirectional, making it suitable for protecting circuits that experience voltage transients in one direction. Fabricated from silicon, the SMAJ12A features a DO-214AC (SMA) surface mount package that is halogen-free and RoHS compliant, aligning with environmental and health standards regarding the restriction of hazardous substances in electronic components.
A notable attribute of the SMAJ12A is its capability to offer excellent clamping performance with low inductance. This characteristic is critical for protecting sensitive components by quickly suppressing voltage spikes before they can cause damage. With a breakdown voltage range between 13.3V and 14.7V, this TVS diode ensures precise triggering at the intended voltage levels. Other significant specifications include a maximum forward voltage of 3.5V, a peak reverse voltage of 12V, and a minimal reverse current of 1µA, underlining its efficiency in power dissipation and leakage current control.
