The 2SA984KE is a silicon PNP epitaxial planar transistor manufactured by NEC. It's primarily designed for audio amplifier applications, particularly in the output stages where linearity and power handling are crucial. The 'KE' suffix often indicates specific gain or performance characteristics within the 2SA984 family.

Applications:

• Audio power amplifiers
• Output stages of audio amplifiers
• Hi-Fi audio equipment
• General-purpose amplification

Features:

• PNP silicon epitaxial planar transistor
• High collector current capability
• Low distortion characteristics
• Excellent linearity
• High power dissipation

Benefits:

• Delivers high-quality audio amplification with minimal distortion
• Provides sufficient power to drive speakers effectively
• Ensures clean and accurate signal reproduction
