SMAJ28CA with TVS SMA RoHS manufactured by TWGMC is a surface mount unidirectional transient voltage suppression (TVS) diode device. It is designed to protect components, cables, and other sensitive equipment from overvoltage transients. Its array configuration is an SMAJ series packaged type with a common anode that provides unidirectional protection from the Cathode to the Anode. The SMAJ28CA has a maximum peak pulse power of 500 Watts, a maximum reverse clamping voltage rating of 28 Volts, and it is RoHS compliant (Restriction of Hazardous Substances), meaning that it does not contain a significant number of hazardous substances. The TWGMC part also has a stand-off voltage rating of 10 Volts, a reverse mAV of 28 Amps, and an IEC-610004-2 air gap discharge rating of 5 Amps.
