The KMPS8550D is a PNP silicon epitaxial transistor manufactured by KEC (Korea Electronics Co., Ltd.). It is designed for use in various switching and amplification applications.

Applications

• General purpose switching circuits
• Amplifier circuits
• Driver stages in electronic circuits
• Load switch

Features

• High collector current (IC = -1.5A)
• Low saturation voltage (VCE(sat) = -0.4V max @ IC = -1A)
• High hFE, typically 85 - 340
• Complementary to the KMN3904D (NPN transistor)
• Surface Mount Device (SMD) package

Benefits

• Provides efficient switching performance due to low saturation voltage.
• Offers good amplification characteristics with high hFE.
• Reduces board space due to its compact SMD package.
• Easy to design into circuits due to readily available models and datasheets.
• Reliable performance from a reputable manufacturer (KEC).

Additional Details

The KMPS8550D comes in a SOT-89 package. Its absolute maximum ratings include a collector-base voltage (VCBO) of -60V, a collector-emitter voltage (VCEO) of -40V, and an emitter-base voltage (VEBO) of -5V. The maximum collector current (IC) is -1.5A, and the power dissipation is 1W. The operating and storage junction temperature range is -55°C to +150°C. It is commonly used in circuits where a PNP transistor with moderate current and voltage handling capability is required.
