1N6819

(MSASC75W45F)

Features

• Tungsten schottky barrier

• Oxide passivated structure for very low leakage currents

• Guard ring protection for increased reverse energy capability

• Epitaxial structure minimizes forward voltage drop

• Hermetically sealed, low profile ceramic surface mount power package

• Low package inductance

• Very low thermal resistance

• Available as standard polarity (strap is anode: 1N6819) and reverse

polarity (strap is cathode: 1N6819R)
