Description:
The DIG-11-15-30-SM Photovoltaic is a State-of-the-Art, optically-coupled floating power source used primarily to
control MOSFET/IGBT’s when electrical isolation between input and output is required. It is particularly well suited for
Medical implant applications.
In addition to the infrared LED and photovoltaic (PV) diode array, each of the DIG-11-15-30-SM devices contains
circuitry that rapidly discharges the power MOSFET/IGBT gate when the LED is deactivated. The unique rapid discharge
feature of the DIG-11-15-30-SM makes it particularly useful for high side switching of MOSFET/IGBT’s in Medical
applications, DC motor control and switching regulator applications. The rugged design features a hard ceramic top, 2
hard sides and of course a hard ceramic bottom. Therefore, it is ideal for manual and automatic vacuum pencil assembly
methods, with handling damage almost impossible.
The typical input circuit to the LED is a limiting resistor connected in series with the LED. When activated, the LED
emits infrared light towards the photovoltaic diode array, which then responds by generating an open circuit voltage (V
and disabling the turn off circuitry. The self-limiting photovoltaic output of the diode array is floating and therefore, can
be safely applied directly to the MOSFET/IGBT, regardless of the source potential of the MOSFET/IGBT. When the LED
is deactivated, the active turn-off circuit discharges the capacitive input of the MOSFET/IGBT. The active turn-off
circuitry is designed such that the turn-off time of the MOSFET/IGBT is relatively independent of the input capacitance
over a range of 300 to 5000 pF.
