41W x 4 Class AB amplifier for multi-channel audio
The STMicroelectronics TDA7387EP is a Class AB audio amplifier delivering 41 watts per channel into 4-ohm loads across four channels. That power level suits aftermarket car radio head units, powered subwoofer modules, and compact multi-room audio systems where a single IC drives a full speaker set.
Flexiwatt package and thermal integration
Housed in a 25-Flexiwatt package with formed leads, the TDA7387EP mounts vertically through-hole on a PCB — the metal tab on the back of the package is designed to be bolted directly to a heatsink or chassis. This vertical orientation keeps the hot surface away from the board and lets the heatsink sit in the airflow path, which is standard for automotive audio modules where space above the PCB is tight. The operating temperature range of -30°C to 85°C covers the cabin environment of a parked car in winter or summer, but it does not extend to under-hood or engine-bay duty — the amplifier is designed for the passenger compartment.
