BD677AS [Onsemi]

BD677AS Overview

DC current gain in this device equals 750 @ 2A 3V, which is the ratio of the base current to the collector current.The collector emitter saturation voltage is 2.8V, giving you a wide variety of design options.Saturation of VC means the Ic value is at its maximum, so vce saturation (Max) is 2.8V @ 40mA, 2A.Single BJT transistor is essential to maintain the continuous collector voltage at 4A to achieve high efficiency.An emitter's base voltage can be kept at 5V to gain high efficiency.Current rating refers to the maximum current a fuse can carry for an indefinite period without deteriorating substantially, and this device has a 4A current rating.As a result, the part has a transition frequency of 3MHz.Breakdown input voltage is 60V volts.In extreme cases, the collector current can be as low as 4A volts.
