BF421-AP Overview
As the DC current gain is the ratio of the collector current to the base current, for this device the DC current gain is 50 @ 25mA 20V.As a result of vce saturation, Ic reaches its maximum value (saturated), and vce saturation(Max) is 600mV @ 5mA, 30mA.Single BJT transistor is possible to achieve a high level of efficiency by maintaining the emSingle BJT transistorter base voltage at 5V.Its current rating is -500mA, which means that it can sustain a maximum current for an indefinite period of time without degrading too much.Single BJT transistor can take a breakdown input voltage of 40V volts.During maximum operation, collector current can be as low as 500mA volts.
BF421-AP Features
the DC current gain for this device is 50 @ 25mA 20V
