SMAJ13CA with TVS SMA RoHS is an electronic component manufactured by Shikues. It is a TVS (Transient Voltage Suppressor) - SMA (Surface Mount Assembly), ESD (Electrostatic Discharge) device, also known as a surge protector. This component is designed to protect against voltage transients in low voltage and medium voltage circuits. It is a two-terminal, ultra-low capacitance, fast response element with very low clamping voltage. It is RoHS compliant (Restriction of Hazardous Substances) and has a standoff voltage of 13 volts. This component is suitable for high-density, portable electronic device applications, such as portable phones, MP3 players, PDAs, and digital cameras.
