BD544-S Product Details

BD544-S Overview


This device has a DC current gain of 15 @ 5A 4V, which is the ratio between the collector current and the base current.A collector emitter saturation voltage of -1V ensures maximum design flexibility.As a result of vce saturation, Ic reaches its maximum value (saturated), and vce saturation(Max) is 1V @ 1.6A, 8A.Single BJT transistor is possible to achieve a high level of efficiency by maintaining the emSingle BJT transistorter base voltage at 5V.In extreme cases, the collector current can be as low as 8A volts.

BD544-S Features


the DC current gain for this device is 15 @ 5A 4V
a collector emitter saturation voltage of -1V
the vce saturation(Max) is 1V @ 1.6A, 8A
the emitter base voltage is kept at 5V
