Gate-driven 30 V MOSFET for 10 A loads, fast PWM from 3.3 V
The ET-MD14 is built around the NCE3080K N-MOSFET 30V 80A, ~6.5mΩ at 10V gate, low-side. It runs from Gate supply 10–18V (usually the 12V load supply); load supply up to 24V.
Designed in Dubai by ElectroTrical — the full schematic, BOM and design notes are published below.
Good for
- Heaters and LED strips
- Solenoids and pumps
- High-frequency PWM loads
