Question

In the construction of tunnnel diode,why is the pellet soldered to anode contact and a tindot to cathode contact via a mesh screen?

(a) for better conduction and reduce inductance respectively

(b) for heat dissipation and increase conduction respectively

(c) for heat dissipation and reduce induction respectively

(d) for better conduction and reduce inductance respectively

This question was posed to me in semester exam.

My question is from Tunnel Diodes and its Characteristics topic in chapter Semiconductor-Diode Characteristics of Electronic Devices & Circuits

Answer 1

Right option is (c) for heat dissipation and reduce induction respectively

The best explanation: Anode goes through better heat dissipation. So the pellet is used for the purpose. The tindot via mesh screen resists inductive effects caused at the cathode. Conduction is an independent factor which can’t be controlled.
