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.
Increases efficiency of
photovoltaic arrays
Protects photovoltaic cells from
reverse voltage
MAXIMUM RATINGS @ 25°C (UNLESS OTHERWISE SPECIFIED)
