Chapter 6: Transistors and Gain
physics.wm.eduBipolar transistors come in two basic types: npn and pnp. The current flow in a npn transistor shown schematically in the accompanying figure 6.2, below. Current (conventional, positive) goes in through the base terminal and out the emitter and the amplified current flows from the collector to …

Insulated Gate Bipolar Transistor (IGBT) Basics
www.ixys.comThe Insulated Gate Bipolar Transistor (IGBT) is a minority-carrier device with high input impedance and large bipolar current-carrying capability. Many designers view IGBT as a device with MOS input characteristics and bipolar output characteristic that is a voltage-controlled bipolar device. To make use of the advantages of both Power
Fundamentals of Gallium Nitride Power Transistors
epc-co.comTransistors have efficient cooling paths to both the top and bottom of the device. Using top side cooling allows for the highest current and power density of these transistors. Mounting a heat spreader to threaded surface mount standoffs around the power FETs controls FET to a heat spreader gap that is inexpensive to manufacture.
