The BC107 is an NPN small-signal BJT available in different variants like; BC107A, BC107B, & BC107C where each has slightly special specifications. The main variation between these three variants is their hFE (current gain) range. So, BC107A transistor hFE ranges from 110 to 220, BC107B transistor has 200 to 450 ranges and BC107C transistor has 420 to 800 ranges. Based on the requirements of your application, a suitable variant is selected. This transistor is well-known in various circuit … [Read more...]

The transistor is a three-terminal semiconductor electronic device, used as a switch or an amplifier. Generally, transistors can be available in either PNP/NPN polarity with different switching and power speed ratings. If a transistor handles >1 Amps of collector current, then it is considered generally as a power transistor. These transistors must have less output resistance to deliver huge load currents and good junction insulation to oppose high voltages. These transistors can also … [Read more...]
