Continuation of prior question: Logic level mosfet to switch on 3.7v battery
I am a 'mature' entrepeneur Arduino level electronics noob, apologies. Want to build a flashing alert using 3W LEDs in parallel powered from a 3P 18650 (3.7V) battery pack. I think I have crude solutions using LEDs in series and a 3S battery pack, but not appealing due to uneven LED performance in series configuration, and problems with charging a 3S (balancing, access to 5V/USB charging solutions).
The last answers/comments recommended then un-recommended a P-channel MOSFET, specifically the FQP27P06, because the max Vgs(th) was too high at 4V. In 'fun with sparks' websites I found the Fairchild NDP6020P as an alternative. Finally my question. The Vgs(th) for this MOSFET is -0.4 min to -1 max. Seems like this would be exceeded when I'm using 3.7V source. Consequence, could be MOSFET destruction up to small burst of shrapnel, counterproductive for a safety invention. I read about protecting with a Zener diode and series resistor, but that seems complicated and also primarily designed for surges and polarity reverses.
Kinda yes or no, am I going down the right road with the Fairchild NDP6020P? Bonus points for continuing my education, and much appreciated.
