Description

KST42MTF Overview
The DC current gain is the ratio of the base current to the collector current βdc = Ic/Ib and the DC current gain for this device is 40 @ 30mA 10V.With a collector emitter saturation voltage of 500mV, it offers maximum design flexibility.Vce saturation means Ic is at its maximum value(saturated), and the vce saturation(Max) is 500mV @ 2mA, 20mA.If the emitter base voltage is kept at 6V, a high level of efficiency can be achieved.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 500mA.A transition frequency of 50MHz is present in the part.There is a breakdown input voltage of 300V volts that it can take.Collector current can be as low as 500mA volts at its maximum.

KST42MTF Features
the DC current gain for this device is 40 @ 30mA 10V
a collector emitter saturation voltage of 500mV
the vce saturation(Max) is 500mV @ 2mA, 20mA
the emitter base voltage is kept at 6V
the current rating of this device is 500mA
a transition frequency of 50MHz
