Temperature Effects on performance of diode

Posted by AJ On Tuesday, 9 July 2013 0 comments

• As temperature increases it adds energy to the diode.

• It reduces the required Forward bias voltage in Forward Bias condition

• It increases the amount of Reverse current in Reverse Bias condition

• It increases maximum Reverse Bias Avalanche Voltage

• Germanium diodes are more sensitive to temperature variations than Silicon Diodes.

Resistance Levels

• Semiconductors act differently to DC and AC currents.

There are 3 types of resistances.

• DC or Static Resistance

• AC or Dynamic Resistance

• Average AC Resistance
