BD678 Overview

This device has a DC current gain of 750 @ 1.5A 3V, which is the ratio between the collector current and the base current.As a result of vce saturation, Ic reaches its maximum value (saturated), and vce saturation(Max) is 2.5V @ 30mA, 1.5A.A 4A continuous collector voltage is necessary to achieve high efficiency.Emitter base voltages of 5V can achieve high levels of efficiency.According to definition, current rating describes the maximum current a fuse can carry indefinitely without deteriorating too much, and this device has no current rating.The product comes in the supplier device package of TO-225AA.The device exhibits a collector-emitter breakdown at 60V.When collector current reaches its maximum, it can reach 4A volts.
