Find Green 0603 LED Stock
Thought for 1 min 4 sec
For a 5 V low-side drive through the same 2N7002K MOSFET arrangement, the series-resistor values per color at 20 mA (and their nearest E24 values) are:
Table
| LED Color | Vf_typ (V) | If (mA) | R = (5 V – Vf_typ) / If | Nearest E24 Value |
|---|---|---|---|---|
| Blue / Green | 3.5 | 20 | (5 – 3.5)/0.02 = 75 Ω | 75 Ω |
| Orange | 2.0 | 20 | (5 – 2.0)/0.02 = 150 Ω | 150 Ω |
If you prefer lower currents (10 mA), simply double each:
Table
| LED Color | If (mA) | R = (5 – Vf_typ)/0.01 | Nearest E24 |
|---|---|---|---|
| Blue / Green | 10 | 150 Ω | 150 Ω |
| Orange | 10 | 300 Ω | 300 Ω |
Recommended parts in 0603 to search/add:
- MOSFET
- LED current-limit resistors (0603)
- Gate series resistor
- Gate pull-down
Hook-up reminder:
- LED anode → 5 V → RLED → LED1 → MOSFET D
- MOSFET S → GND
- ESP32 GPIO → 100 Ω → MOSFET G
- MOSFET G → 100 kΩ → GND
