ZTX551STZ Overview

As dc = Ic/Ib, DC current gain is the ratio of base current to collector current, and DC current gain for this device is 50 @ 150mA 10V.A collector emitter saturation voltage of -350mV allows maximum design flexibility.Vce saturation?means Ic is at its maximum value(saturated), and the vce saturation(Max) is 350mV @ 15mA, 150mA.Continuous collector voltages of -1A should be maintained to achieve high efficiency.A high level of efficiency can be achieved if the base voltage of the emitter remains at -5V.According to definition, current rating describes the maximum current a fuse can carry indefinitely without deteriorating too much, and this device has no current rating.In this part, there is a transition frequency of 150MHz.Collector current can be as low as 1A volts at its maximum.
