KEY FEATURES
DESCRIPTION
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
Oxide passivated structure for
very low leakage currents
Epitaxial structure minimizes
forward voltage drop
Triangular shape to fit in corner
near flat of photovoltaic cell
Forward voltage decreases with
radiation exposure
Targeted for terrestrial
applications with silicon
photovoltaic cells
Thin construction for fit with
photovoltaic cells
W W W. Microsemi .COM
Large area diode chip for medium current photovoltaic bypass applications, or for higher current hybrid applications.
The device is rated for 1A for applications where the device
will be exposed to substantial radiation flux (space). For
other applications, it may be operated at higher currents. A
version with attached leads is available.
