The SMCJ19A is a high-performance, unidirectional Transient Voltage Suppressor (TVS) diode manufactured by JCET (JSCJ). Supreme Components International is an authorised distributor of JCET components. This surface-mount TVS diode, housed in an SMC package, offers robust protection against voltage transients. With a power dissipation of 600W and a reverse standoff voltage of 19V, it effectively clamps voltage spikes, preventing damage to sensitive electronic components. Its unidirectional configuration ensures optimal protection for DC circuits. The SMCJ19A is suitable for a wide range of applications, including automotive, industrial, and consumer electronics, where reliable surge protection is crucial. Its compact size and high surge capability make it an excellent choice for protecting against ESD, EFT, and lightning strikes.
