FDP20N50 TO-220 FDP 20N50 MOSFET Power Transistors in Pakistan

The bipolar NPN Transistor is an age-old Japanese Bipolar audio frequency NPN transistor. 2SC945 50V NPN transistor has a decent gain value (have) of maximum 700 and is highly linear. Hence this bipolar transistor was widely used in amplifier applications for pre-amplifying purposes, in high-frequency circuits. This NPN junction transistor is also used as an oscillator with its complementary A733 PNP transistor.

The BT136 is TRIAC with 4A maximum terminal current. The gate threshold voltage of the BT136 is also very less so can be driven by digital circuits. Since TRIACs are bi-directional switching devices they are commonly used for switching AC applications. So if you looking to switch control (dim, speed control) to an AC load that consumes less than 6A with a digital device like a microcontroller or microprocessor then BT136 might be the right for you.
