Stk412530 Datasheet Jun 2026

The absolute maximum rating is 150 W per channel, but this depends on the load impedance and supply voltage. In typical hi‑fi applications with an 8‑ohm speaker and a ±36 V supply, you can expect approximately 90 W to 110 W of clean, continuous power per channel.

If you're interested, I can amplifier (like the STK412-030).

The electrical characteristics of the STK412-530 are as follows: stk412530 datasheet

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.

The is a premier two-channel, high-power audio power amplifier integrated circuit (IC) originally developed by SANYO Electric Co., Ltd. . Engineered specifically for high-fidelity (Hi-Fi) audio systems, professional sound reinforcement, and demanding home theater systems, this discrete hybrid module is widely celebrated for its ability to deliver an impressive 150W + 150W of continuous output power .

A typical circuit using the STK412-530 requires several external components for stable operation: The electrical characteristics of the STK412-530 are as

This is critical. Due to the high power output, the IC requires a large aluminum heatsink to prevent thermal shutdown. Input Capacitors: Used to block DC signals.

Often includes thermal and over-voltage protection to ensure longevity. 2. STK412-530 Specifications and Technical Data
