I am looking to spec in this part in my design where I'm using it in a battery powered app, where the battery sits on the input side unused for up to 2 years, then when the device is powered the battery gets used. Previously I have used a regulator that has very low leakage in the off state (2nA over temp), but I need this switch now because I use a 100uf capacitor in parallel with the battery -- upstream of the regulator, and this capacitor is too leaky (the previous ceramic capacitor had issues with board flexing and would fail, so I now need to use a tantalum polymer). I'm trying to isolate this capacitor with the switch by putting it downstream, but I need low leakage on the switch during the storage time. I have tested a few of the parts and the leakage is ~10-20nA for the ones I tested which is consistent with the datasheet, but I would like to get the production distribution for the off-state leakage so I can know what to expect in large volumes. The datasheet shows max of 1uA, but that would be too large for my application, and I know based on the typical numbers that the parts will likely be closer to typical. If I could get the production test distribution for this part (histogram) for the leakage in the off-state then I could confidently spec this part in. Please help!
