The SMF48A is a high-performance Transient Voltage Suppressor (TVS) Diode manufactured by SMC Diodes. Supreme Components International is an authorised distributor, ensuring you receive authentic components directly from the source. This TVS diode is specifically designed to protect sensitive electronic equipment from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). Featuring a standoff voltage of 48V and a power dissipation of 400W, the SMF48A effectively clamps transient voltages to safe levels, preventing damage to downstream circuitry. Its DO-219AB package allows for easy surface mounting and efficient heat dissipation. Ideal for use in telecommunications, industrial control, and consumer electronics applications where reliable overvoltage protection is critical. Choose the SMF48A for superior circuit protection.
