For devices below approximately 200 V, this region becomes less significant. Advanced high voltage devices utilize a technique called “charge balance” which is used to reduce conduction loss in the epitaxial region. With power MOSFETs, the conduction channel resistance is determined by the channel length, the distance through which carriers must flow, and channel width, is the amount of transistor channel that is constructed in parallel. Lower resistance is achieved by increasing the channel width for a given silicon area.

This, as any resistance in an emitter, produces an amplified resistance as seen from the base. In fact staying with this numeric example, an emitter current of 1 mA, in addition to a 26 mV drop in the emitter-base voltage, will produce a base current Transistors 29 variation of approximately 10 pA ( 1 mA divided by an amplification of + 1 o r 101). 6 kL2 Naturally such transfer of resistance from low in the emitter to high in the base is the property that gives the name transistor or, transfer resistor to the electrical component.

Ongoing changes to these technologies will further enhance both the conduction and switching performance of the existing trench MOSFETs. As a result, the improvements will deliver increasingly better performance. , ohmic resistance, wire inductance) packages. Figure 2-14 shows a power Ball Grid Array (BGA) package capable of delivering unprecedented levels of power thanks to the substitution of the wire bonds solder balls. A surrounding drain frame structure, which dramatically reduces the package resistance and inductance parasitics, is another important benefit of BGA packaging.
