The Sanken SE-B2 is a NPN silicon power transistor with a TO-220 package.
It is designed for use in switching power supplies, inverters, and motor control circuits.

High breakdown voltage: VCEO = 800V
High collector current: IC = 10A
Low collector-emitter saturation voltage: VCE(sat) = 0.2V
Low collector-emitter saturation voltage: VBE(sat) = 0.9V
Low thermal resistance: Rth(j-c) = 0.8°C/W
