Stk411-210e Datasheet
STK411-210E
The is a thick-film hybrid integrated circuit primarily used as a Class H audio power amplifier, though it also appears in industrial power control and specific TV applications. Performance Review
STK411-210E
I've been reviewing the datasheet for the – a thick-film hybrid IC from Sanyo (now onsemi). It's designed for use in audio power amplifiers, typically in stereo applications. Stk411-210e Datasheet
- Output Power
- Total Harmonic Distortion
- Supply Voltage
- Number of Channels
Efficiency
: As a Class H module, it utilizes a dual-rail power supply system (often ±40V) to improve efficiency and reduce heat dissipation during lower volume levels. STK411-210E The is a thick-film hybrid integrated circuit
Without the actual datasheet, I can only speculate on the specifics. The "STK" prefix might suggest a product from Sanyo (which is now part of ON Semiconductor), a well-known manufacturer of electronic components. The "411" could indicate a particular series or family of products, while "-210e" might denote a specific model or version within that series.

Sample Schematic Overview (Dual Supply):
Availability:
As an older hybrid module, it is often found as "New Old Stock" (NOS) or original parts from distributors like Jotrin or Veswin . STK-411-210E SANYO INTEGRATED CIRCUIT STK411-210E
Practical advice
: Reuse a heatsink from a vintage amplifier rated for 50W/channel. Mount the STK module with thermal grease directly on the metal backside (no insulator needed).
Class-AB
The STK411-210E is a , dual-channel (stereo) audio power amplifier IC. It is packaged in a compact, isolated SIP (Single Inline Package) that includes built-in power transistors, driver stages, and bias circuitry. The "210E" suffix indicates a specific voltage/power variant within the STK411 series.
