Stk411-210e Datasheet

In summary – The STK411-210E datasheet “story” is a ghost: a once-common part lost to time, where only the base STK411-210 specs survive. If you need to service an old stereo using that module, treat it as an STK411-210 and verify with a curve tracer or low-voltage test before powering up.

The STK411-210E is a high-performance 2-channel audio power amplifier hybrid integrated circuit (IC) manufactured by Sanyo. Designed primarily for home theater systems, professional sound equipment, and high-fidelity stereo applications, it is part of the renowned STK series known for robust output and consistent audio quality. Key Technical Specifications

According to technical summaries from Alibaba and other electronic component databases, the STK411-210E features:

Output Power: Approximately 105 watts per channel (into an 8-ohm load).

Operating Voltage: Typically operates with a supply voltage around ±40V, providing high dynamic range and headroom.

Package Type: Housed in a ZIP-22 (Zig-Zag In-line Package) or DIP-22P module, which facilitates easy mounting on a heatsink.

Temperature Range: Specified for operation from -40°C to 105°C (TA).

Total Harmonic Distortion (THD): Typically remains below 0.1% to preserve audio signal integrity. Pinout and Internal Architecture

The STK411-210E is a thick-film hybrid IC, meaning it integrates discrete transistors and resistors on a ceramic substrate to optimize heat dissipation.

Integrated Functions: The module includes internal driver stages, biasing circuits, and muting capabilities to eliminate "pop" noise during power-up.

Protection Features: Built-in thermal shutdown protection prevents damage by disabling the amplifier if internal temperatures exceed safe limits (often around 125°C substrate temperature).

BTL Support: It supports Bridge-Tied Load (BTL) configurations, allowing the two channels to be combined for high-power mono output (potentially up to 400W depending on the setup). Application and Sourcing Guide

The STK411-210E was a staple in 1990s and early 2000s audio equipment but has since been discontinued by Sanyo/Panasonic.

Repairs and DIY: It remains highly sought after for repairing vintage AV receivers and for DIY audio enthusiasts who prefer its "warm, musical" analog sound profile over modern Class-D alternatives. Stk411-210e Datasheet

Sourcing: You can still find "New Old Stock" (NOS) or refurbished units through specialized distributors like Veswin Electronics or Jotrin Electronics.

Installation Tip: Always use high-quality thermal paste and an appropriately sized heatsink. Operating the IC without a heatsink will cause immediate and permanent failure. Ic Stk411 210e(968) - Alibaba
