BD681S Overview
In this device, the DC current gain is 750 @ 1.5A 3V, which is calculated by taking the ratio of the base current to collector current and dividing transistor by two.A collector emitter saturation voltage of 2.5V ensures maximum design flexibility.Saturation of VCE means Ic is at its maximum value (saturated), and VCE saturation (Max) is 2.5V @ 30mA, 1.5A.Maintaining the continuous collector voltage at 4A is essential for high efficiency.Keeping the emitter base voltage at 5V allows for a high level of efficiency.A fuse's current rating indicates how much current it will be able to carry over an indefinite period, and this device has a current rating of (4A).10MHz is present in the transition frequency.Maximum collector currents can be below 4A volts.
