1. Type PNP (Positive-Negative-Positive) transistor: This means the current flows from the emitter to the collector. Small, low-power, and versatile: Ideal for various electronic circuits. 2. Ratings and characteristics Collector-Emitter Voltage (Vce): Typically -25V. Collector-Base Voltage (VCBO): Typically -40V. Emitter-Base Voltage (VEBO): Typically -5V to -6V. Collector Current (Ic): Varies depending on the manufacturer and specific model, ranging from -0.5A to -1.5A. Some sources mention a typical maximum of 700mA. Power Dissipation (Pd): Varies, with some sources listing 300mW and others stating around 625mW. Some variants like the SS8550 can dissipate 1W. DC Current Gain (hFE): Ranges from 85 to 400 depending on the variant and conditions, with typical values between 110 and 300. Transition Frequency (ft): Typically around 150MHz or 200MHz. Operating Temperature Range: Broad, from -55°C to 150°C.
