12V Photo-voltaic Diode Stack

The 14SCT000 is a 12V photo-diode stack with an active clamp circuit. The active clamp circuit keeps a low anode to cathode resistance when light intensity is below a few mW/cm2. When light intensity is above this threshold, the clamp is disconnected and normal photo-voltaic anode – cathode voltage is applied.

The active clamp is very useful in controlling unwanted FET turn-on due to dV/dT at the FET’s drain. The 14SCT000 delivers steady performance across the entire extended temperature range of -55°C to +125°C.
