SANTA ANA DIVISION
Photovoltaic By-Pass Diode
50 Volts, 1.0 Amps
PRODUCT PREVIEW
DESCRIPTION
Large area diode chip for medium current photovoltaic by-
pass 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.
KEY FEATURES
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
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
APPLICATIONS/BENEFITS
Increases efficiency of
photovoltaic arrays
Protects photovoltaic cells from
reverse voltage
