FEATURES
For general purpose applications.
♦
These diodes feature very low
♦
turn-on voltage an d f a st 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 Mini-MELF
case with type designations LL46.
