QST7TR Overview

This device has a DC current gain of 270 @ 100mA 2V, which is the ratio between the collector current and the base current.The collector emitter saturation voltage is -200mV, giving you a wide variety of design options.VCE saturation indicates Ic is at maximum level (saturated), whereas vce saturation (Max) indicates there is no saturation.A -1.5A continuous collector voltage is necessary to achieve high efficiency.With the emitter base voltage set at -6V, an efficient operation can be achieved.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.Parts of this part have transition frequencies of 280MHz.An input voltage of 30V volts is the breakdown voltage.The maximum collector current is 1.5A volts.
