Integration Tips for Arduino/Raspberry Pi 💡

• Gate drive: The IRF630 is not a logic‑level MOSFET; use a dedicated gate driver or provide ~10–12 V gate drive for low losses. Direct drive from a microcontroller GPIO (3.3/5 V) is not recommended.
• Thermal management: Mount to a suitable heatsink to utilize the TO‑220 thermal capability and maintain reliability at higher currents.
• Inductive loads: Use a flyback diode or snubber across motors, relays, and inductors to protect the MOSFET.
• Layout: Keep high‑current paths short and use low‑impedance returns to reduce ringing and EMI in high‑frequency designs.
