BF862 - low-noise N-Channel JFET (counterfeit?) : weekend die-shot

Designed for AM radio preamps, but found much wider use in low-noise amplifiers. SOT-23 marking 2Ap 48.
Identified by Jeroen Ponte as probably counterfeit - which is especially likely as NXP stopped production of the original part.
Die size 426x399 ┬Ám.
