The SMF12A-MS-H is a high-performance 12V Unidirectional 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 peak pulse power dissipation of 400W, the SMF12A-MS-H effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its DO-219AB (SMF) package offers a compact footprint for space-constrained applications. As an authorized distributor of FORMOSA MICROSEMI, Supreme Components International guarantees the authenticity and quality of this TVS diode. This robust component is suitable for a wide range of applications, including automotive, industrial, and consumer electronics.
