2SA2151 and 2SC601: Allegro Announces Two New Single Transistors For Audio Amplifiers

2SA2151
Audio Amplification Transistor

Features

• Small package (TO-3P)
• High power handling capacity, 160 W
• Improved sound output by reduced on-chip impedance
• For professional audio (PA) applications, V_CEO = –200 V versions available
• Complementary to 2SC6011
• Recommended output driver: 2SA1668

Applications

• Single transistors for audio amplifiers
• Home audio amplifiers
• Professional audio amplifiers
• Automobile audio amplifiers
• Audio market
• Single transistors for general purpose

Description

By adapting the Sanken unique wafer-thinner technique, these PNP power transistors achieve power-up by decreasing thermal resistance, and provide higher voltage avalanche breakdown rating. The high power-handling capacity of the TO-3P package allows a smaller footprint on the circuit board design. This series of transistors is very well suited to not only multichannel applications for AV (audio-visual) amplifiers and receivers, but also parallel connection applications for PA (professional audio system) amplifiers.
