The SM4F14CA-MS-Q1-H is a surface-mount Transient Voltage Suppressor (TVS) diode manufactured by Formosa Microsemi. Supreme Components International is an authorised distributor of Formosa Microsemi components, ensuring you receive genuine and reliable parts. This TVS diode is designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). It features a peak pulse power dissipation of 400W and a reverse standoff voltage of 14V. The SM4F14CA-MS-Q1-H comes in a compact DO-214AA (SMB) package, making it suitable for space-constrained applications. Its fast response time and low clamping voltage provide excellent protection against transient threats. This diode is ideal for use in automotive, industrial, and telecommunications equipment.
