Product Overview
The 2SD1047 is an NPN bipolar power transistor designed for audio-frequency power amplification and high-current driver applications. It features a 140V collector-emitter voltage rating, 12A maximum collector current, and up to 120W power dissipation. Its relatively high current capability and 15MHz transition frequency make it suitable for power amplifier output stages and other medium-speed power-control circuits.
Packaged in a TO-3PN through-hole package, the 2SD1047 is suited to heatsink-mounted designs requiring substantial thermal handling. It can be used in audio power amplifiers, high-current driver stages, load-control circuits, and other power applications requiring a combination of voltage headroom and current capability.
