BF421ZL1 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.Single BJT transistor has a collector emSingle BJT transistorter saturation voltage of -500mV, which allows maximum flexibilSingle BJT transistory in design.As a result of vce saturation, Ic reaches its maximum value (saturated), and vce saturation(Max) is 500mV @ 2mA, 20mA.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 -50mA, which means that it can sustain a maximum current for an indefinite period of time without degrading too much.Parts of this part have transition frequencies of 60MHz.During maximum operation, collector current can be as low as 50mA volts.
