Stk412530 Datasheet Jun 2026

You can perform a basic "diode check" using a multimeter:

This device is part of the STK410-XXX series, which includes lower and higher power variants (e.g., STK412-020, STK412-170). The "530" suffix typically indicates a specific gain and output power configuration optimized for 6-ohm speakers, making it ideal for mini and midi audio systems from the 1990s and early 2000s.

At least 1.5°C/W thermal resistance (e.g., 100x100x40mm extruded aluminum finned heatsink). Apply thermal grease and use insulating washers if the heatsink is grounded.

Exceeding any of the following may cause permanent damage to the STK412‑530. These limits are stress ratings only; functional operation at or near these values is not implied and should be avoided.
