Stk412-230 Datasheet Pdf Jun 2026
Before soldering the new chip in place, test the external emitter resistors (usually large, white ceramic block resistors rated at 0.22 to 0.47 ohms). If the original IC shorted out, it may have blown these resistors open. Installing a new IC with open emitter resistors will prevent the amplifier from working or damage the new chip.

The is a two-channel, high-efficiency Class H audio power amplifier hybrid integrated circuit (IC) originally developed by Sanyo (now part of Panasonic ) . It is widely used in high-fidelity (Hi-Fi) audio systems, home theaters, and professional sound reinforcement equipment due to its ability to deliver high output power with minimal thermal loss. Key Technical Specifications
: Provides 150W + 150W (two channels) at low total harmonic distortion (THD).
This component is considered an older or "obsolete" part but remains available through specialized distributors and marketplaces: Before soldering the new chip in place, test
Before designing a PCB or troubleshooting, always consult the for stress limits. Exceeding these values will destroy the IC.

If the exact STK412-230 is unavailable, you might search for a substitute. The STK412 family is largely pin-compatible across different power levels. This means that a higher-powered chip like the or a lower-powered one like the STK412-210 could potentially be used in its place with appropriate heatsinking and power supply considerations. The key difference is the number of pins, so always verify compatibility before attempting a replacement. Some online discussions indicate the STK412-440 could also be a substitute for the STK412-230 and STK412-240.
