The SM4F33CA-MS-H is a high-performance Transient Voltage Suppressor (TVS) Diode manufactured by Formosa Microsemi. As an authorised distributor, Supreme Components International offers this reliable component for your circuit protection needs. This TVS diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). With a breakdown voltage of 33V and a power dissipation of 400W, the SM4F33CA-MS-H effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its DO-214AA package allows for easy surface mounting on printed circuit boards. Ideal for use in telecommunications, industrial control, and consumer electronics applications where robust overvoltage protection is critical.
