TDA2030 18W Hi-Fi Audio Power Amplifier IC (TO-220-5)

Where the LM386 is built for tiny battery-powered speaker projects, the TDA2030 targets a meaningfully higher power class, delivering up to 18W into a standard speaker load for projects that actually need room-filling volume rather than a quiet notification beep. Its TO-220-5 package is designed to bolt onto a heatsink, which matters at this power level since sustained high-volume output generates real heat that a bare chip alone couldn't dissipate. It is a common choice for DIY stereo amplifier builds, powered speaker projects, and hi-fi mod circuits where the goal is genuinely good sound reproduction at a usable listening volume rather than just basic audio output.
