SBJ18x SMD Schottky Barrier Rectifier Diodes Diotec Semiconductor SBJ18x SMD Schottky Barrier Rectifier Diodes offer high-power dissipation, low forward voltage drop, and an isolated heat flange. SBJ18x diodes feature a 280A to 320A peak forward surge current, 950pF typical junction capacitance, and an 18A maximum average forward rectified current in a -50°C to +150°C junction temperature range. The ITO-220AC packaged SBJ18x SMD Schottky Barrier Rectifier Diodes are ideal for output rectification in DC-DC converters/power supplies, polarity protection, free-wheeling diodes, solar bypass diodes, and commercial-grade applications.
