WebA typical value of β for a standard bipolar transistor may be in the range of 50 to 200 and varies even between transistors of the same part number. In some cases where the current gain of a single transistor is too low to directly drive a load, one way to increase the gain is to use a Darlington pair. Webvalue specified as an absolute maximum rating is a voltage at the specified current. The maximum V(BR)CBOvalue is smaller than VB. The temperature coefficient of VBis positive because it is related to carrier mobility. Since ICBOincreases with temperature, the V(BR)CBOvalue may become smaller in the low-current region at high temperature.

WebA transistor works by feeding a current into the base of the transistor. The base current is then amplified by h FE to yield its amplified current. The formula is below: I C = h FE I B =βI B So if 1mA is fed into the base of a transistor and it has a h FE of 100, the collector current will be 100mA. Every transistor has its own unique h FE. http://www.ee.nmt.edu/~anders/courses/ee321f11/hw06.pdf
