BD438S Overview

This device has a DC current gain of 30 @ 10mA 5V, which is the ratio between the collector current and the base current.The collector emitter saturation voltage is -200mV, giving you a wide variety of design options.VCE saturation indicates Ic is at maximum level (saturated), whereas vce saturation (Max) indicates there is no saturation.The emitter base voltage can be kept at -5V for high efficiency.Its current rating is -4A, which means that it can sustain a maximum current for an indefinite period of time without degrading too much.In this part, there is a transition frequency of 3MHz.Maximum collector currents can be below 4A volts.
