    Products Detail

    BD678A Overview


    In this device, the DC current gain is 750 @ 2A 3V, which is the ratio between the base current and the collector current.This system offers maximum design flexibility due to a collector emitter saturation voltage of 2.8V.Single BJT transistor means that Ic is at Single BJT transistors maximum value (saturated), so the vce saturation(Max) is equal to 2.8V @ 40mA, 2A.A 4A continuous collector voltage is necessary to achieve high efficiency.With the emitter base voltage set at 5V, an efficient operation can be achieved.As defined by current rating, the maximum current a fuse can carry without deteriorating too much is -4A for this device.Single BJT transistor contains a transSingle BJT transistorion frequency of 10MHz.Input voltage breakdown is available at 60V volts.Single BJT transistor is possible for the collector current to fall as low as 4A volts at Single BJT transistors maximum.

    BD678A Features


    the DC current gain for this device is 750 @ 2A 3V
