BD677A Overview
This device has a DC current gain of 750 @ 2A 3V, which is the ratio between the collector current and the base current.The collector emitter saturation voltage is 2.8V, which allows for maximum design flexibility.VCE saturation indicates Ic is at maximum level (saturated), whereas vce saturation (Max) indicates there is no saturation.Continuous collector voltage should be kept at 4A for high efficiency.An emitter's base voltage can be kept at 5V to gain high efficiency.Its current rating is 4A, which means that it can sustain a maximum current for an indefinite period of time without degrading too much.In the part, the transition frequency is 10MHz.The maximum collector current is 4A volts.
