Hello Guys! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to BD136. BD136 is a medium power general-purpose transistor mainly used for switching and audio amplification purposes. It belongs to the PNP transistor family and comes with collector current 1.5A, indicating it can drive loads under 1.5A. The amplification factor ranges from 40 to 250, which means it can amplify the input signal up to 250 times. Both collector-emitter and collector-base voltages are 45V while the emitter-base voltage is 5V, indicating only 5V is required to bias this transistor. I suggest you read this entire post, as I’ll be detailing complete introduction to BD140 covering pinout, working principle, power ratings, applications, and physical dimensions ...
