The SMBJ78A-H is a high-performance Transient Voltage Suppressor (TVS) diode manufactured by Formosa Microsemi. Supreme Components International, an authorised distributor, provides this essential component for safeguarding electronic circuits. This diode is specifically engineered to protect sensitive devices from voltage transients caused by events such as lightning strikes, inductive load switching, and electrostatic discharge (ESD). With a power dissipation rating of 600W and a standoff voltage of 78V, the SMBJ78A-H effectively clamps transient voltages to safe levels, preventing damage to downstream components. Its SMB package allows for easy surface mounting on printed circuit boards. Ideal for use in telecommunications equipment, industrial controls, and consumer electronics, the SMBJ78A-H ensures reliable overvoltage protection in demanding environments.
