The SMBJ17CA-H is a high-performance 17V unidirectional Transient Voltage Suppressor (TVS) diode manufactured by Formosa Microsemi. Supreme Components International is an authorised distributor of Formosa Microsemi, ensuring you receive genuine components. This TVS diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a power dissipation rating of 600W, it effectively clamps transient voltages to safe levels. The SMB package allows for efficient surface mount assembly. Ideal for use in telecommunications, industrial control, and consumer electronics applications where reliable overvoltage protection is critical. Its unidirectional configuration provides optimal protection for DC circuits.
