Product Summary

The blf1043 is a Silicon N-channel enhancement mode lateral D-MOS transistor encapsulated in a 2-lead flange package (SOT467C) with a ceramic cap. The common source is connected to the mounting flange. The blf1043 is used for Communication transmitter applications in the UHF frequency range.

Parametrics

blf1043 absolute maximum ratings: (1)drain-source voltage: 65 V; (2)VGS gate-source voltage: ±20 V; (3)ID drain current (DC): 4.5 A; (4)Tstg storage temperature: − 65 to +150 °C; (5)Tj junction temperature: 200 °C.

Features

blf1043 features: (1)High power gain; (2)Easy power control; (3)Excellent ruggedness; (4)Source on underside eliminates DC isolators, reducing common mode inductance; (5)Designed for broadband operation (HF to 1 GHz).
