BC640BU 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 40 @ 150mA 2V.As it features a collector emitter saturation voltage of -500mV, it allows for maximum design flexibility.When VCE saturation is 500mV @ 50mA, 500mA, transistor means Ic has reached transistors maximum value (saturated).An emitter's base voltage can be kept at 5V to gain high 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 (-1A).The maximum collector current is 1A volts.
