I need to build a circuit where the trigger voltage of a SCR is corrected for a temperature range using a thermistor, so that the voltage at which the scr triggers remains the same over a range of temperatures.
I'm guessing I need to match the V/T ratio of the gate to the r/t ratio of the thermistor. Is there a standard table or method for selecting components?
For example I'd be using a BT151 series sct and a 100R thermistor.
