DIP4 VTL5C M1210CLC 5PCS
I have never done anything with Vactrols yet, so it might take a while until I get around to test them properly.
for now I just hooked up my multimeter in resistance mode and used an oldish 3V coin cell to drive the LED for a few seconds.
I measure an OFF resistance well into the 1-10 MOhm range and an ON resistance of 60-100 Ohm, which almost sounds too good to be true to me.
