NPN Transistor Unit

Product Code : SCL-EE-12408

Quick Answer: The NPN Transistor Unit is a teaching unit for demonstrating NPN transistor operation, in which a small base current controls a larger collector-emitter current in a correctly biased teaching circuit.

Last updated: October 2026

Key Features

Teaches emitter, base and collector identification
Supports lessons on biasing, current gain and switching action
Shows base current controlling collector current
Allows comparison with PNP transistor circuits

About This Product

Students identify the three terminals, connect the unit to the teacher's diagram with resistors to limit base and collector current where required, and add meters if base current, collector current or voltage changes are to be observed. Switching on the low-voltage supply then shows the transistor's response and introduces switching and basic amplifier behaviour. The NPN Transistor Unit is available for supply within India and for export to Guyana, Kazakhstan, South Sudan, Egypt and Georgia.
