Part Number : BF981
Function : 20V, 20mA, DUAL GATE MOSFET
Package : SOT-103 Type
Manufactures : Philips Semiconductors
This is 20V, 20mA, Silicon N-Channel Dual Gate MOSFET.
Depletion type field-effect transistor in a plastic X-package with source and substrate interconnected, intended for v.h.f. applications, such as v.h.f. television tuners, f.m. tuners and professional communication equiment. This MOSFET tetrode is protected against excessive input voltage surges by integrated back-to-back didodes between gates and source.
1. Drain-source voltage : Vds = max. 20V
2. Drain current : Id = max. 20mA
3. Total power dissipation up to Tamb = 75’C : Ptot = max. 225mW
