FEATURES
MiniMELF
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 DO-35 case with type designation BAT47.
