Stk412530 Datasheet Jun 2026

High-power amplified signal for the left/first speaker.

: The moment a transient peak or loud musical passage demands more headroom, the internal controller switches to the higher voltage rail (

The STK412-530 is engineered using a Class-H topology, which SANYO details as a "two-channel shift power supply". Traditional Class-AB amplifiers continuously run on a high-voltage rail, wasting massive amounts of energy as heat when playing quiet audio signals.

The STK412-530 is part of a pin-compatible series that includes models like STK412-090, STK412-140, STK412-150, STK412-170, and STK412-190. These models cover power ratings from 50W×2 to 180W×2 and can be used as drop-in replacements with the same PCB.

Measure the voltage at the output pins (before the relay). If you see high DC voltage (close to the rail voltage), the IC is blown.
