Tp view 1 2 MAM39 s,b DESCRIPTION Depletin type field-effect transistr in a plastic micrminiature SOT143 r SOT143R package. The transistrs are prtected against excessive input vltage surges by integrated back-t-back dides between gates and surce. CAUTION The device is supplied in an antistatic package. The gate-surce input must be prtected against static discharge during transprt r handling. BF98 marking cde: %M1.
