30 - 60 VOLTS , 1 AMP , 6.25 WATTS

D40D is a power transistor designed for various specific and general purpose applications, such as: output and driver stages of amplifiers operating at frequencies from DC to greater than 1.0 MHz; series, shunt and switching regulators; low and high frequency inverters/converters; and many others.

FEATUREs:
• High free-air power dissipation
• NPN complement to D41D PNP
• Low collector saturation voltage (0.5V typ. @ 1.0A lc)
• Excellent linearity
• Fast Switching
