Hi all, finally got around to testing these LND150's back to back (in series) as input protection. After playing with my signal generator, I plugged this into the AC wall outlet.
Does someone make them as single piece units? (two terminal devices.) And if so what are they called?
Trolling DK I found a few others that would work at V=0 GS. (not using the resistor trick... See AoE3 Fig 5.80, 5.81) BSS126 ~ 300 ohms till ~8V and then limits at ~23 mA. BSS139 maybe 10 ohms and limits at 1V to 70 mA.
Any others?
Finally has anyone looked at the noise? (In the linear region, not where the current clips.) Are they really like a resistor with a diode in series?
Thanks
