An avalanche diode conducts 0.5mA with a forward voltage drop of 0.7V. What is its saturation current I(s) ? a) What current will flow in the diode if the forward voltage bias is raised to 0.8V? b) What current will flow in the diode if the forward voltage bias is lowered to 0.6V? c) What change in forward bias voltage will increase the diode current by a factor of 10?
