Stk411-210e Datasheet
Specified to operate between -40°C and 105°C . Features & Protection
Includes power transistors, driver stages, and thermal protection.
Designed for split (dual) power supplies, typically operating between $\pm$15V and $\pm$54V.
The STK411-210E is a reliable and efficient power amplifier IC, designed for high-quality audio applications. Its high power output, low distortion, and wide operating voltage range make it an excellent choice for a variety of audio equipment designs.
The STK411-210E belongs to Sanyo’s famous STK series of hybrid ICs, which utilize insulated metal substrate technology (IMST). This construction technique places discrete transistors, resistors, and capacitors onto a single thermal-conducting substrate, ensuring excellent thermal stability, matched component aging, and a highly compact footprint compared to fully discrete amplifier builds. Key Features: Stk411-210e Datasheet
Contains necessary peripheral components to simplify PCB design.
Designed to withstand high temperatures, though external heat dissipation is mandatory. Compact Design:
: Despite its efficiency, a high-quality aluminum heatsink with thermal paste is essential. Poor thermal dissipation is a primary cause of failure for these modules.
The following table summarizes the key specifications of the STK411-210E: Specified to operate between -40°C and 105°C
If you meant (or a variant with an “E” suffix for lead-free/export version), here’s the likely narrative:
The module must be mounted on a large, high-efficiency aluminum heatsink.
A: Yes, generally. The STK400 series (including 210E, 200E, 220E, 240E) uses standard pinouts across similar power ranges, but verification of the specific circuit diagram is essential.
Since Sanyo discontinued these modules, many "new" units on the market are clones. Genuine units usually have sharper laser-etched text and better weight due to the metal substrate. What is the supply voltage of your transformer? The STK411-210E is a reliable and efficient power
Yes, with some considerations, as the STK411-210E is part of a larger interchangeable series. Electronics repair forums document that this is a common technique:
