D1047 or 2SD1047 is a TO-3P package NPN transistor, it is designed to be used as audio and power amplification purposes. This post describes D1047 transistor pinout, features, equivalent, applications and other info.

D1047 Transistor Explained / Description:

D1047 is an NPN transistor manufactured in the TO-3P package. The transistor is mainly designed for audio amplification and power amplification purposes. The transistor has good specs due to which it is not only limited to the above-mentioned purposes and can be used for a variety of other applications. The maximum collector-emitter voltage is 140V due to which it can be used in many different high voltage applications under 140V. The maximum collector-emitter value of 140V doesn’t mean that you cannot use this transistor in low-power and battery-operated circuits the maximum collector-emitter voltage value only describes the maximum voltage load this transistor can withstand.

Moreover, the maximum collector current is 12A which makes it ideal to use as a switch in a variety of applications, the total power dissipation is 100 Watts, the maximum transition frequency is 15MHz and the maximum DC current gain of the transistor is 200.
