BD679A Overview

This device has a DC current gain of 750 @ 2A 3V, which is the ratio between the collector current and the base current.With a collector emitter saturation voltage of 2.8V, it offers maximum design flexibility.A VCE saturation (Max) of 2.8V @ 40mA, 2A means Ic has reached its maximum value(saturated).Continuous collector voltages should be kept at 4A to achieve high efficiency.Keeping the emitter base voltage at 5V can result in a high level of efficiency.Fuse current ratings refer to how much current the fuse can carry for an indefinite period without deteriorating too much, and this device has a current rating of 4A.Single BJT transistor contains a transSingle BJT transistorion frequency of 10MHz.Maximum collector currents can be below 4A volts.
