Analysis:
| Parameter | 2SK3564 | SVF5N80F | Match? |
|---|---|---|---|
| V<sub>DS</sub> | 800V | 800V | ✅ Yes |
| I<sub>D</sub> | 5A | 5A | ✅ Yes |
| R<sub>DS(on)</sub> | ~2.5Ω | ~1.9Ω | ✅ Better |
| Package | TO-220 | TO-220F (Insulated) | ⚠️ Slightly different |
| Power Dissipation | ~60W | ~70W | ✅ Yes |
| Gate Threshold Voltage | ~2 – 4V | ~2 – 4V | ✅ Yes |
⚠️ Caution:
The TO-220F package is fully insulated, unlike the TO-220 package of K3564 which may require a mica insulator when mounted on a heatsink.
Ensure thermal dissipation is managed accordingly.
Check PCB pinout compatibility, though most TO-220 variants follow the same pin configuration (G-D-S).
✅ Conclusion:
Yes, SVF5N80F is a suitable substitute for K3564 (2SK3564) in the power supply section of the HP M1005 printer as long as:
The thermal design accommodates the slightly different package.
The pinout is confirmed to be the same.
