For ESD purposes, the “K” and “B” suffixes in part names have the same meaning. A “K” or "B" in the suffix of an op amp denotes an HBM ESD rating of 2 kV. For example, LM324K, LM324KA, LM324B, LM2902K, LM2902KA, LM2902B, LM2902KAV, LM2904B and LM358B all have a 2-kV HBM rating.
When greater ESD protection is desired, incorporate system-level ESD solutions into the design.
