Stk411-210e Datasheet !!link!! Instant

Supports a wide split power supply rail architecture ranging from (with extreme limits reaching up to depending on thermal control).

The STK411-210E appears in various consumer-grade audio systems, including models from:

This is . Such a regulator is a very different class of device. The overwhelming weight of evidence from multiple independent sources—including repair forums, technical specifications, and application notes—consistently and authoritatively identifies the STK411-210E as a 100-watt audio amplifier . Engineers and hobbyists should therefore disregard the regulator specification page if their goal is circuit design or repair.

The is a classic, modestly-powered audio amplifier IC from the golden age of Japanese stereo equipment. While often subject to misinformation regarding its power output, the official datasheet confirms it is a 10W x 2 channel chip. It remains relevant today mostly for restoring vintage audio gear like JVC and Sony mini-systems. When repairing, it is critical to verify the actual IC in the device, check the supply voltages (±17V to ±26V), and use a compatible replacement from the STK4102II series to maintain the intended sound quality and safety.

The ZIP-22 footprint houses 22 inline pins configured in a zig-zag orientation to allow effortless single-layer or double-layer PCB routing. The pin topology separates sensitive low-voltage analog inputs from high-current DC power rails and speaker outputs, minimizing internal electromagnetic crosstalk.

: Integrated into larger audio units for standard and commercial applications.

:

Uses IMST substrates for superior heat dissipation, reducing the risk of thermal runaway.

Confirm balanced positive and negative voltages at the power pins. A asymmetry of more than

The is a high-performance, two-channel thick-film hybrid audio power amplifier integrated circuit designed by SANYO Electric Co., Ltd. Widely integrated into classic home theater systems, midi stereos, and professional audio setups, this monolithic-like component utilizes SANYO’s legendary Insulated Metal Substrate Technology (IMST). This specialized construction method ensures reliable thermal dissipation and stable audio output over extended periods of operation. Supports a wide split power supply rail architecture

The STK411-210E is manufactured by ON Semiconductor (formerly Sanyo).
