STN749 [STMicroelectronics]

STN749 Overview

DC current gain' is equal to the ratio of the collector current to the base current, something like Ic/Ib, and this device has 100 @ 1A 2V DC current gain.VCE saturation indicates Ic is at maximum level (saturated), whereas vce saturation (Max) indicates there is no saturation.Keeping the emitter base voltage at 5V can result in a high level 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.Single BJT transistor can be broken down at a voltage of 25V volts.When collector current reaches its maximum, it can reach 3A volts.
