Transistors in Pakistan
Explore a wide range of transistors in Pakistan for electronics repair, circuit design, switching, amplification, motor control, power electronics, Arduino projects, robotics and DIY electronic applications. Transistors are fundamental semiconductor components used to control current, amplify signals and switch electronic circuits.

Our transistor range includes popular NPN, PNP, MOSFET and Darlington transistors suitable for low-power signal circuits, switching applications and higher-current loads. Popular transistor part numbers include 2N2222, BC547, BC548, BC557, BC558, 2N3904, 2N3906, S8050, S8550, TIP31C, TIP32C, TIP41C, TIP42C, TIP122, IRF520 and IRFZ44N.
NPN & PNP Transistors
NPN transistors such as BC547, 2N2222, 2N3904 and S8050 are commonly used for signal amplification, switching, LED control, relay driving and microcontroller interfacing.

PNP transistors such as BC557, 2N3906 and S8550 are useful for high-side switching, complementary amplifier circuits and general-purpose electronic designs.
Power Transistors & MOSFETs
For higher-current applications, power transistors and MOSFETs provide efficient switching and load control. Devices such as TIP31C, TIP41C, TIP122, IRF520 and IRFZ44N are commonly used in motor control, LED drivers, power switching, robotics, battery systems and other electronics projects.

MOSFETs are particularly useful where efficient switching and low conduction losses are required. Select the appropriate device according to drain/source current, voltage rating, gate-drive requirements, power dissipation and package type.
Transistor Applications
