SS34A with Schottky Barrier Diodes (SBD)SMA (DO-214AC) RoHS is a surface mount diode manufactured by Hottech. It has a metal semiconductor junction, also known as a Schottky Barrier, which allows the diode to have low forward voltage drop and high surge capability. The SS34A has a reverse voltage of 30V and a low forward voltage drop of 0.35V @ 10mA, which helps to keep power dissipation low. The SMA package has a maximum power dissipation of 350mW. This diode is compliant to RoHS guidelines and is widely used in telecommunication, consumer electronics, automotive, and industrial applications.
