BAT48JFILM-BAT48ZFILM
Small signal Schottky diodes
T48Small signal Schottky diode
Features Low leakage current losses Negligible switching losses Low forward and reverse recovery times Extremely fast switching Surface mount device Low capacitance diode
DescriptionThe BAT48 series uses 40 V Schottky barrier
diodes packaged in SOD-123, SOD-323 or
DO-35. This series is general purpose and
features very low turn-on voltage and fast
switching.
