The SMBJ40CA-Q1-H is a high-performance Transient Voltage Suppressor (TVS) diode manufactured by FORMOSA MICROSEMI. This diode is specifically engineered to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a breakdown voltage of 40V and a clamping voltage of 64.5V, the SMBJ40CA-Q1-H effectively diverts surge current away from protected circuits. Its SMB (DO-214AA) package allows for efficient heat dissipation and easy surface mounting. Supreme Components International is an authorized distributor of FORMOSA MICROSEMI components, guaranteeing the authenticity and quality of this TVS diode. This component is suitable for automotive applications and various industrial and consumer electronics where reliable overvoltage protection is crucial.
