The SMBJ43CA-H is a Transient Voltage Suppressor (TVS) diode from Formosa Microsemi. Supreme Components International is an authorised distributor of Formosa Microsemi components, ensuring you receive genuine and reliable parts. This diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching. It features a reverse standoff voltage of 43V and a breakdown voltage of 66.4V. The SMBJ43CA-H is packaged in a compact SMB (DO-214AA) package suitable for surface mount technology (SMT). Its fast response time and low clamping voltage make it an excellent choice for protecting I/O interfaces, VCC bus, and other vulnerable circuits. This robust diode enhances the reliability and longevity of your electronic designs. Ideal for industrial, automotive, and consumer electronics applications.
