The SMA6J43A-H is a unidirectional Transient Voltage Suppressor (TVS) diode manufactured by FORMOSA MICROSEMI. Designed to protect sensitive electronic equipment from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching, this TVS diode offers a robust and reliable solution. With a standoff voltage of 43V and a peak pulse power dissipation of 600W, the SMA6J43A-H effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its unidirectional configuration provides protection against positive polarity transients. The compact SMA (DO-214AC) package allows for easy integration into various circuit designs. Supreme Components International is an authorized distributor of FORMOSA MICROSEMI, guaranteeing the authenticity and quality of this TVS diode. Ideal for use in telecommunications, industrial control, and consumer electronics applications.
