> Zener gate to ground:........ I've seen it seldom elsewhere

I notice that Silicon Chip are using it lately, and push-pull drive

Attached is what I'd typically use between a PIC and a FET

Q1 and Q2 can be ordinary BJT, eg BC337, BC327, or low Vsat
fast-switching high-current like Zetex ZTX450, ZTX550. hFE for
either is several hundred so R2 can be anything over 270 ohms,
keeping in mind the PIC pin's 20mA

R3 is 10 ohms, D1 is 12V or 15V
