BF421ZL1 Overview
In this device, the DC current gain is 50 @ 25mA 20V, which is calculated by taking the ratio of the base current to collector current and dividing transistor by two.With a collector emitter saturation voltage of -500mV, it offers maximum design flexibility.In VCE saturation, Ic is at its maximum value (saturated), and the vce saturation (Max) is 500mV @ 2mA, 20mA.The emitter base voltage can be kept at 5V for high efficiency.In definition, current rating refers to the maximum current a fuse can carry for an indefinite period without deteriorating too much, and the current rating of this device is -50mA.In the part, the transition frequency is 60MHz.Maximum collector currents can be below 50mA volts.
