Stk412530 Datasheet Jun 2026

: Maximum operating IC substrate temperature of 125°C . Package : Compact SIP-ZIP (Single Inline Package). Functional Features

This construction allows the device to handle higher power levels and dissipate heat more effectively than a standard plastic IC package. The STK412530 is typically used in audio amplifier circuits found in consumer electronics.

The STK412530 is a designed for audio power amplification. Unlike a standard silicon chip, a "Hybrid" IC contains a ceramic substrate with thick-film printed resistors and capacitors, onto which discrete semiconductor chips (transistors and diodes) are bonded.

Designed for high-end consumer audio, the chip maintains minimal total harmonic distortion (THD) across the human hearing frequency spectrum. Absolute Maximum Ratings

that has earned its stripes among audiophiles and DIY builders alike. stk412530 datasheet

The module is designed for "Class H" (shifted power supply) operation, which improves efficiency by switching between high and low voltage rails based on the audio signal level. SeekIC.com Output Power : Typically delivers 120W to 150W per channel

Exceeding any of the following may cause permanent damage to the STK412‑530. These limits are stress ratings only; functional operation at or near these values is not implied and should be avoided.

The is a two-channel, high-power hybrid audio frequency power amplifier integrated circuit (IC) originally developed by Sanyo Semiconductor . Widely known in the audiophile and repair community as a "thick-film" module, it is engineered to deliver clean, dual-channel power to demanding audio loads.

STK412-150 SANYO Original Audio Integrated Circuit + HEAT SINK COMPOUND : Maximum operating IC substrate temperature of 125°C

The STK412-530 features a multi-pin single in-line layout. Accurate tracking of these pins is vital during troubleshooting or PCB trace routing.

The STK412-530 uses an 18-pin SIP (Single Inline Package). The following table lists the typical pin assignment for the STK412 series:
