Datasheet _top_ | Stk412530
According to the official Sanyo documentation, the STK412-530 is a designed specifically for surround sound systems of the late 1990s and early 2000s. It is essentially a multi-channel workhorse.
The is a legendary, high-performance two-channel thick-film hybrid audio power amplifier integrated circuit (IC) originally engineered by Sanyo (now part of ON Semiconductor). Highly praised by audiophiles and hardware repair engineers, this module is widely used in high-fidelity (Hi-Fi) home theater receivers, professional sound gear, and custom audio setups. Operating on an efficient Class H topology with dynamic high/low dual power supply rail shifting, it delivers up to 120W to 150W per channel of clean analog power into a 6-ohm load while drastically cutting down on thermal waste.
: The series is pin-compatible across different power ratings (50W to 180W), allowing a common PCB design for various output classes.

The STK412-000 series features a unified pin layout. Designers can use the exact same printed circuit board (PCB) for amplifiers ranging anywhere from 50W × 2 channels up to 180W × 2 channels. Absolute Maximum Ratings
, a high-performance audio power amplifier IC known for its reliability and "thick-film" hybrid design. What is the STK412-530 STK412-530
The STK412530 is a class AB audio power amplifier IC designed by SANYO Electric Co. (now part of ON Semiconductor). It is a dual-channel (stereo) amplifier capable of delivering 30 watts per channel into a 6-ohm load (or 25W into 8 ohms) with low distortion. It is built using SANYO’s proprietary thick-film hybrid technology, which combines discrete transistors, resistors, and capacitors on a ceramic substrate, all encapsulated in a plastic package. Highly praised by audiophiles and hardware repair engineers,
Whether you’re repairing a classic or building a custom rig that can wake the neighbors, here is why the STK412-530 is still a heavyweight in the audio world. 1. Raw Power Meets High Efficiency STK412-530 Go to product viewer dialog for this item.
