2SA1287

The 2SA1287 is a silicon PNP epitaxial type transistor. Designed with high voltage, high collector current, dissipation and high hFE. The feature of 2SA1287 are as follows: (1)high hFE hFE = 400 to 800; (2)high voltage VCEO = -50V; (3)low collector to emitter saturation voltage. VCE = -0.2V typ(@IC = -500mA, IB = -10mA); (4)high collector dissipation Pc = 900mW.

The absolute maximum ratings of the 2SA1287 are: (1)collector to base voltage: -50V; (2)emitter to base voltage: -6V; (3)collector to emitter volatge: -50V; (4)peak collector current: -2A; (5)collector current: -1A;(6)collector dissipation: 900mW; (7)junction temperature: +150; (8)storage temperature: -55 to +150.
