DESCRIPTION
Enhancement type N-channel field-effect transistor with
source and substrate interconnected. Integrated diodes
between gates and source protect against excessive input
voltage surges. The BF1211, BF1211R and BF1211WR
are encapsulated in the SOT143B, SOT143R and
SOT343R plastic packages respectively.
