BAT54HT1
SURFACE MOUNT SCHOTTKY BARRIER DIODES Reverse Breakdown Voltage - 30 Volts
SOD-323
Peak Forward Current - 200mA
These Schottky barrier diodes are designed for high speed switching applications,circuit protection,and voltage clamping. Extremely low forward voltage reduces conduction loss. Miniature surface mount package is excellent for hand held and portable applications where space is limited. * Extremely Fast Switching Speed * Low Forward Voltage - 0.35 Volts (Typ) @ IF = 10mAdc * Device Marking : JV
