BF421ZL1G Overview

DC current gain' is equal to the ratio of the collector current to the base current, something like Ic/Ib, and this device has 50 @ 25mA 20V DC current gain.Single BJT transistor offers maximum design flexibilSingle BJT transistory wSingle BJT transistorh a collector emSingle BJT transistorter saturation voltage of -500mV.Vce saturation?means Ic is at its maximum value(saturated), and the vce saturation(Max) is 500mV @ 2mA, 20mA.With the emitter base voltage set at 5V, an efficient operation can be achieved.Current rating refers to the maximum current a fuse can carry for an indefinite period without deteriorating substantially, and this device has a -50mA current rating.Single BJT transistor contains a transSingle BJT transistorion frequency of 60MHz.Maximum collector currents can be below 50mA volts.
