ZTX557 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 @ 50mA 10V.This design offers maximum flexibility with a collector emitter saturation voltage of -300mV.Saturation of VC means the Ic value is at its maximum, so vce saturation (Max) is 300mV @ 5mA, 50mA.In order to achieve high efficiency, the continuous collector voltage should be kept at -500mA.A high level of efficiency can be achieved if the base voltage of the emitter remains at -5V.This device has a current rating of -500mA which corresponds to the maximum current it can carry for an indefinite period without deteriorating too much.Single BJT transistor contains a transSingle BJT transistorion frequency of 75MHz.A maximum collector current of 500mA volts is possible.
