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 Mini-MELF case with type
designation LL85.
