SEMICONDUCTOR
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.
These diodes are also available in the DO-35 case with the type
designation BAT42 to BAT43.
High temperature soldering guaranteed:260℃/10 seconds at terminals
Component in accordance to RoHS 2002/95/EC and WEEE 2002/96/EC
MECHANICAL DATA
Case: MiniMELF glass case(SOD-80 )
Weight: Approx. 0.05 gram
