Stk413-430 Circuit Diagram Exclusive Jun 2026

: Do not exceed ±38V DC. Use a 100W to 150VA transformer.

The STK413–430 series are hybrid audio power amplifier modules (commonly produced as STK413/416/418/420/425/430, etc.) used in consumer stereo and AV equipment. Each STK module integrates discrete power transistors, biasing, and protection components into a single package, providing a compact way to build high-power amplifier channels with fewer external parts. Typical use is in bridged or single-ended class-AB audio outputs for home receivers. stk413-430 circuit diagram

Typically 20W + 20W (with variations up to higher peak outputs depending on load). Operating Voltage: Maximum supply voltage of plus or minus 34.5 cap V Total Harmonic Distortion (THD): depending on the specific application. Pin Compatibility: : Do not exceed ±38V DC
