Absorption and transfer of heat in surrounding air for stud-mounted diodes occur by the mechanisms of ____________
a. Conduction & Convection
b. Convection & Radiation
c. Conduction & Radiation
d. Conduction, Convection & Radiation
Correct Answer: b. Convection & Radiation
Generally, soldering is the process adopted for mounting the low and high medium current diodes. These diodes generate very less quantity of heat. But, stud- mounted diodes produce maximum amount of heat for which air convection is insufficient.
Therefore, necessity of heat sink arises which plays a cardinal role in absorbing and then transferring it to the surrounding medium by means of convection as well as radiation due to availability of maximum surface area.
