Hello,

Yes, transistor is included in the JEE Main 2026 Physics syllabus .

Topics generally covered are:

• Junction transistor and its working

• Characteristics of a transistor

• Transistor as an amplifier (common-emitter)

• Transistor as a switch

• Basic use of transistor in simple circuits

Hope it helps !

Hello,

No, transistors are not in the JEE Main 2026 syllabus, as the topics of junction transistors, transistor action, and transistors as amplifiers or switches have been removed from the semiconductor and electronics devices chapter. Here in this article you will find more about the JEE Main syllabus.

I hope it will clear your query!!

You can get the syllabus for the JEE examination for all the three subjects present viz Physics, chemistry and mathematics in the updated pdf format from the link given below by careers 360 to get the Idea of deleted and revised syllabus for the session of 2026

Hello

Transistors are not included in the JEE Main 2026 syllabus.
They were part of the deleted Physics topics like the junction transistor and its applications.
So you don’t need to study transistors for JEE Main now. You can find the updated syllabus by visiting the link I am attaching below, so that you can find all the details
