BD678AG Overview

As explained above, DC current gain takes into account the rate at which the base current flows through the collector current; therefore, DC current gain for this device is 750 @ 2A 3V.A collector emitter saturation voltage of 2.8V allows maximum design flexibility.VCE saturation indicates Ic is at maximum level (saturated), whereas vce saturation (Max) indicates there is no saturation.The emitter base voltage can be kept at 5V for high efficiency.As defined by current rating, the maximum current a fuse can carry without deteriorating too much is 4A for this device.The breakdown input voltage is 450V volts.During maximum operation, collector current can be as low as 4A volts.
