Additional Details:

The STS9014 is typically available in a TO-92 package, which is suitable for through-hole mounting. Key specifications include collector-emitter voltage (VCEO), collector current (IC), power dissipation (PD), and current gain (hFE). It is important to consult the datasheet for the specific values and operating conditions. This transistor is designed to operate within a specified temperature range, typically from -55°C to +150°C. The DC Current Gain (hFE) is a critical parameter for amplification applications, indicating the transistor's ability to amplify a small base current into a larger collector current.
