Transistor (for high school)
Transistor (for high school) (Product Code: SCL234/037) is an NPN bipolar transistor used to show how a small base current controls a much larger collector current in school electronics and physics practicals. Rated for a maximum allowable collector current of 1 A, it suits switching circuits with LEDs or small lamps as well as the curves plotted with a transistor characteristics kit. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the High School Transistor Used For?
A good starting circuit uses the transistor as a switch: an LED or small lamp sits in the collector circuit, and a resistor feeds the base from a second, weaker path. Touching the base connection on and off turns the load on and off, showing that a tiny control current can govern a larger one. Adding a light dependent resistor to the base divider turns this into an automatic night light, a popular project for class 11 and 12 students.
For quantitative work, students hold the collector-emitter voltage steady, vary the base current and record the collector current, then repeat at other voltages to draw the output characteristics used in common emitter amplifier experiments. Identify the emitter, base and collector leads from the part marking before wiring, always include a base resistor, and keep currents well below the 1 A limit.

Frequently Asked Questions
Is this an NPN or a PNP transistor?
The Transistor (for high school) is an NPN bipolar transistor. If you also want PNP devices so students can compare current directions and biasing, the PNP Transistor listed above can be added to the same order.
What current and voltage can it handle?
The Transistor (for high school) has a maximum allowable collector current of 1 A, and its voltage rating is listed as 300 V. Typical school circuits run far below both limits, which leaves a wide safety margin.
What is the maximum junction temperature?
The junction temperature figure in our source listing for the Transistor (for high school) is unclear, so it is not quoted here. Contact us and we will confirm the rating for the parts supplied with your order.
How do I tell which lead is which?
Use the part marking on the Transistor (for high school) you receive to identify the emitter, base and collector before wiring. If you need the pin arrangement in writing for student worksheets, ask us when you place the order.
Can it be used without a base resistor?
No. The Transistor (for high school) should always be used with a base resistor, which limits the base current and protects the device. Connecting the base straight to a supply can pass excessive current and destroy the transistor.
Who supplies the Transistor (for high school)?
The Transistor (for high school) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. Schools can order it with LEDs, light dependent resistors and multimeters in one enquiry through the contact page.
Can you supply class sets or export orders?
Yes. For class sets of the Transistor (for high school), send the code SCL234/037, the quantity and your delivery location, and we will quote for schools in India or international markets.
