Temperature Effects<br />
As temperature increases it adds energy to <strong>th</strong>e diode.<br />
• It reduces <strong>th</strong>e required forward bias voltage for forwardbias<br />
conduction.<br />
• It increases <strong>th</strong>e amount of reverse current in <strong>th</strong>e reversebias<br />
condition.<br />
• It increases maximum reverse bias avalanche voltage.<br />
Germanium diodes are more sensitive to temperature<br />
variations <strong>th</strong>an silicon or gallium arsenide diodes.<br />
