Part of a series (50W to 180W) that shares the same pin layout, allowing one PCB design to support multiple power grades.

If you are repairing an audio amplifier, home theater system, or high-end stereo receiver, you may have encountered the . This component is a specific model within the popular STK series of hybrid integrated circuits manufactured by Sanyo (now part of ON Semiconductor).

The STK412-530 consists of a long row of pins. While the exact pin numbers should be verified on the official datasheet for the specific suffix (e.g., STK412-530-E), the general layout includes:

Typically Vcc+ and Ground (varies by specific series design) Left and Right Channel Outputs Input Pins Requires a bipolar (symmetrical) power supply : The pin arrangement is unified across the

Since Sanyo discontinued many of these modules years ago, many "new" STK412-530 chips on the market are clones. Look for reputable sellers to ensure the internal components meet the original power handling specs. Conclusion

The datasheet provides a standard application circuit featuring:

The is a high-performance, two-channel (stereo) thick-film hybrid integrated circuit (IC) designed for Class H audio power amplification. It is characterized by its high-efficiency "shift power supply" system, which adjusts the operating voltage based on the audio signal level to minimize heat and maximize power. Key Specifications

generates significant heat. You mount it to a substantial heatsink. The most common version is from October 1991

Tip: Always verify pin numbers against the diagram printed on the device itself or the service manual of the unit you are repairing.
