BAT54-HF SMD Schottky Barrier Diodes Comchip Technology BAT54-HF SMD Schottky Barrier Rectifiers combines a fast switching speed, low forward voltage drop, and high current capability. These Schottky Barrier Rectifiers are offered in a surface-mounted SOT-23 package and are RoHS-compliant, halogen-free, and ideal for pick-and-place assembly. These devices feature a 30V maximum repetitive peak reverse voltage (VRRM) and a 21V maximum Root Mean Square (RMS) voltage (VRMS).
