NPN SILICON EPITAXIAL TRANSISTOR
FOR SWITCHING

The 2SC4554 is a power transistor designed especially for low
collector saturation voltage and features large current switching at a
low power dissipation.
In addition, a high hFE enables alleviation of the driver load.

FEATURES
• High hFE and low VCE(sat):
hFE ≅ 800 (VCE = 2 V, IC = 5 A)
VCE(sat) ≅ 0.12 V (IC = 5 A, IB = 0.05 A)
• On-chip C to E damper diode
• Mold package that does not require an insulating board or
insulation bushing
