While it's easy to find ESD ratings for ICs (bipolar, CMOS, and any mix) and to some extent for MOS transistors (for the inherent reasons), I don't find ESD rating for many common diodes (left apart TVS and Zener devices, given their use).
Let's say I'm looking for ESD rating of an S1J or S1M diode: no manufacturer seems to detail it. Is it because being massive, high-voltage parts (operating up to 1kV DC) they already are over an "interesting" value?
Again, if I look for the same rating of a BAS21 part, just a 250V diode, I can't find it from common suppliers.
Even going down to an humble BC847 bipolar NPN, no details on ESD rating, looking in a few data sheets.
If any of these parts is handled wrong, or connected to the outside port of a device, could easily come in contact with dangerous voltages. I'd like to know more on these ratings and why they aren't listed.
