BAT47
SMALL SIGNAL SCHOTTKY DIODES
FEATURES
For general purpose applications
These diodes features very low turn-on voltage and fast switching.
These devices are protected by a PN junction guard ring against
excessive voltage, such as electrostatic discharges.
This diode is also available in the MiniMELF case with the type designation Ll47.
High temperature soldering guaranteed:260℃/10 seconds at terminals
Component in accordance to RoHS 2002/95/EC and WEEE 2002/96/EC
