Stk412530 Datasheet Jun 2026

For accurate integration and to avoid damage, it is for the exact pin numbering and function. The datasheet provides a detailed pinout diagram, electrical characteristics per pin, and recommended external component values for the desired application. As noted in the literature, “designers and engineers must refer to the datasheet provided by the manufacturer to get accurate information regarding each pin's function and electrical characteristics”.

The recommended operating range is ±18 V to ±36 V . For a 4‑ohm load, it is safest to stay at the lower end (e.g., ±24 V to ±28 V) to avoid exceeding the IC’s current limits. For 8‑ohm loads, ±28 V to ±36 V provides an excellent balance of power and reliability.

Sometimes you will see part numbers like STK412-530 or STK412530-S. Often, the 'S' indicates a slightly different internal thermal shutdown characteristic or pin configuration. Always try to match the number exactly as printed on your original unit. If you cannot find an exact match, consult a cross-reference guide, as some STK series are interchangeable.
