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)
