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
