DATA SHEET
SILICON POWER TRANSISTOR
2SD1481
NPN SILICON EPITAXIAL TRANSISTOR (DARLINGTON CONNECTION)
FOR LOW-FREQUENCY POWER AMPLIFIERS AND LOW-SPEED SWITCHING
FEATURES
• On-chip C-to-B Zener diode for surge voltage absorption
• Low collector saturation voltage: VCE(SAT) = 1.5 V MAX. (at 1 A)
• Ideal for use in a direct drive from IC to the devices such as OA
and FA equipment and motor solenoid relay printer head drivers
