BAT42 and BAT43
Small-Signal Diode
Schottky Diodes
Features
ꢀ For general purpose applications.
ꢀ These diodes feature very low turn-on voltage and fast
switching. These devices are protected by a PN junction guard
ring against excessive voltage, such as electrostatic dis-
charges
ꢀ This diode is also available in the MiniMELF case with type
designation LL42 to LL43.
Mechanical Data
ꢀ Case: DO-35 Glass Case
ꢀ Weight: approx. 0.13g
