1N6818
(MSASC75H45F)
Features
• Tungsten/Platinum schottky barrier for very low VF
• 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: 1N6818) and reverse
polarity (strap is cathode: 1N6818R)
