SolutionsThe SMAJ18A is an SMC Diode Solutions-manufactured Transient Voltage Suppressor (TVS) and is made up of a Surface Mounted Avalanche Diode (SMA) in a DO-214AC package. It is RoHS-compliant and is designed to handle pulse voltage ratings of 29.2V, 20V, and 18V. This component is used to protect against transient voltage changes and is typically placed in between a DC power source and the device it is protecting in order to absorb and dissipate certain levels of energy.
