The 2SB1166 is a silicon PNP epitaxial planar transistor manufactured by SANYO Semiconductor (U.S.A) Corporation. Designed for audio frequency power amplifier applications and switching circuits, it offers a good balance of voltage, current, and power handling capabilities.

Applications:

• Audio power amplifiers
• Switching circuits
• Motor drivers
• Relay drivers
• DC-DC converters

Features:

• High Collector Current (IC = -3A)
• Low Saturation Voltage (VCE(sat) = -0.5V max)
• Complementary to 2SD1721
• High Power Dissipation (PC = 1.3 W)
• Good Linearity

Benefits:

• Efficient Power Amplification
• Effective Switching Performance
• Reduced Power Loss
• Improved Circuit Stability
• Simplified Circuit Design

Additional Details:

The 2SB1166 is commonly supplied in a TO-126 type package. The Collector-Emitter Breakdown Voltage (VCEO) is -60V. The DC Current Gain (hFE) typically falls between 100 and 320. The operating temperature range is from -55°C to +150°C. It is crucial to use a proper heat sink, particularly when running at high current levels, to avoid exceeding the maximum junction temperature. The 2SD1721 is the complementary NPN transistor, allowing it to be utilized in push-pull amplifier designs for increased power and efficiency.
