The SMB-W-1SMB5926B~1SMB5956B-3W is a series of surface mount Zener voltage regulators designed for voltage regulation applications. These devices offer a wide zener reverse voltage range from 3.3V to 200V and a total power dissipation of up to 3W. Their small plastic SMB package is suitable for surface-mounted designs, making them ideal for space-constrained electronic circuits.
