The SMBJ12CA with 19.9V 13.3V 12V SMBG TVS ROHS manufactured by High Diode is a low-capacitance, bi-directional Transient Voltage Suppressor (TVS) diode which provides protection against voltage transients generated by a surge or spike. It is specifically designed to protect sensitive electronic components and ICs during electrical transients such as ESD, as well as lightning, local static discharge, or IEC contact discharge. It meets the RoHS specifications for hazardous substances. It is capable of handling a peak pulse power of up to 600W, with a voltage breakdown of 19.9V, 13.3V, and 12V. The working voltage should not exceed 15V, as this could damage the component.
