Types of Transistors

Types of Transistors Points : Types of Transistors, npn - Transistor, pnp - Transistor Transistors are of following two types.
1. npn—type
2. pnp—typc 1. npn - Transistor The npn transistor has a thin piece of p — type material sandwiched between two pieces of n—type material. 2. pnp - Transistor The pnp transistor has a thin piece of n — type material sandwiched between two pieces of p—type material.
