TPAL0220F7R50K9 from RESI, in a TO-220. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | Resistor terminal 1 (non-polarized, 0.5Ω to 10KΩ series, 35W with heatsink and flange at or below 25°C, 500V max working voltage). |
| 2 | 2 | passive | Resistor terminal 2 (non-polarized, 5.08mm lead pitch, 2000VAC isolation between terminals and flange). |
| 3 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
