You need a transistor that actually handles current — not a little signal device that cooks at 100mA. The TIP31 is your answer. TO-220 package, 40W dissipation, 3A collector current, 40V Vcb. Silicon construction in a matt black case. Hfe range of 20 to 100 at 1A bias, 25°C. Drive your motor, switch your relay, run your amplifier. Get it sorted
