BUL38D Overview

This device has a DC current gain of 10 @ 10mA 5V, 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 1.1V.Saturation of VC means the Ic value is at its maximum, so vce saturation (Max) is 1.1V @ 750mA, 3A.Keeping the emitter base voltage at 9V can result in a high level of efficiency.Current rating refers to the maximum current a fuse can carry for an indefinite period without deteriorating substantially, and this device has a 10A current rating.In extreme cases, the collector current can be as low as 5A volts.
