NPN SILICON EPITAXIAL TRANSISTOR

FOR HIGH-SPEED SWITCHING

The 2SC4551 is a power transistor developed for high-speed

switching and features low VCE(sat) and high hFE. This transistor is

ideal for use in drivers such as DC/DC converters and actuators.

In addition, a small resin-molded insulation type package

contributes to high-density mounting and reduction of mounting cost.

FEATURES

• High hFE and low VCE(sat):

hFE ≥ 100 (VCE = 2 V, IC = 2 A)

VCE(sat) ≤ 0.3 V (IC = 6 A, IB = 0.3 A)

• Mold package that does not require an insulating board or

insulation bushing
