Additional Details

The 2SA1012L-Y-TN3-R features a collector-emitter voltage (VCEO) typically around -50V, a collector current (IC) of around -150mA, and a power dissipation (PD) of approximately 250mW, these values should be verified by consulting the UTC datasheet for the specific part. The "L" likely refers to a specific gain ranking. The "Y" designates a specific hFE classification (typically yellow). The "TN3" refers to the package type, often SOT-23. The "-R" at the end denotes tape and reel packaging. It's optimized for low distortion audio amplification and efficient switching performance. Designers should consult the datasheet for safe operating area (SOA) curves and derating factors. The low output capacitance helps to maintain signal integrity in high-frequency applications. Proper biasing is crucial to ensure stable and linear operation.
