BAT54HT1

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 0.106(2.70) 0.091(2.30) 0.071(1.80) 0.063(1.60) 1 2 0.016(0.40) 0.010(0.25) 0.053(1.35) 0.045(1.15) 0.006(0.150) REF. 1 2 2 ANODE NOTE 3 0.007(0.18) 0.004(0.09) NOTES: 0.004(0.10) 0.000(0.00) 0.039(1.00) 0.031(0.80) 1 CATHODE Soldering Footprint 1.
