DO-35
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 Mini-MELF case
with type designation LL42 to LL43and in the SOD-123 case
with the type designation BAT42W to BAT43W,in the Micro-MELF case
with type designation MCL42 to MCL43
