NPN SILICON EPITAXIAL TRANSISTOR

FOR LOW-FREQUENCY POWER AMPLIFIERS

The 2SD1581 is a single type super high hFE transistor and low

collector saturation voltage and low power loss. This transistor is

ideal for use in high current drives such as mortars, relays, and

ramps.

FEATURES

• Ultra high hFE

hFE = 800 to 3200 (@ VCE = 5.0 V, IC = 500 mA)

• Low collector saturation voltage

VCE(sat) = 0.18 V TYP. (@ IC = 1.0 A, IB = 10 mA)
