Designed for replacement and integration in power electronics where TO220F mounting is required. Why this set is useful Ready replacement parts: Five identical TO220F parts make and maintenance faster by keeping spares on hand for power boards and controllers. Standard mounting and cooling: TO220F insulated tab simplifies panel or heatsink mounting and helps manage thermal performance in compact assemblies. Broad compatibility: Multiple model numbers included in the listing enable selection of the correct device for a range of power designs that require these specific parts. Consistent function: Intended for voltage power switching and control functions in power supplies, converters, inverters, and motor drives. Key attributes Function: Power switching transistor suitable for use in switching regulators, inverter stages, motor control circuits, and other power management applications. Package: TO220F insulated package for secure mounting and improved electrical isolation between tab and heatsink. Quantity: 5 pieces per set for bulk replacement or smallscale builds. Models included: SPA20N60C3, 20N60C3, SPA20N60, SPA16N50C3, 16N50C3, SPA17N80C3, 17N80C3, SPA20N65C3, 20N65C3, SPA21N50C3, 21N50C3, allowing selection of the correct part number for the target circuit. Package dimensions and pinout follow standard TO220F conventions for compatibility with existing PCB footprints and heatsinks. Performance and reliability Designed for repetitive switching use in power circuits where thermal management and reliable turn on and turn off are required. TO220F insulation reduces the need for insulating hardware when mounting to conductive heatsinks. Practical applications and scenarios Power supply : failed switching transistors in offline and DC power supplies to restore regulator and converter function. Motor controller maintenance: Use as dropin replacements during service of motor driver boards in industrial equipment or hobby motor controllers. Prototype and small production builds: Keep a set of five identical TO220F devices for testing and short production runs where the specified models are required. What to check before use Confirm that the selected model number matches the original component on the circuit board. Verify mounting orientation and pinout against the PCB design and heatsink arrangement. Ensure appropriate thermal management is applied for the intended operating conditions. This set provides a practical selection of TO220F power switching transistors for , prototyping, and maintenance tasks where the listed model numbers are specified.
