The BLF278,112 is a VHF push-pull power MOS transistor from Ampleon, designed for broadcast transmitter applications in the VHF frequency range. It features a dual N-channel enhancement mode vertical D-MOS structure in a 4-lead SOT262A1 balanced flange package with two ceramic caps, providing common source connection through the mounting flange.
Key electrical specifications include a maximum drain-source voltage of 125 V, drain current rating of 18 A, and power dissipation of 300 W. At 108 MHz in Class-B operation, it delivers typical output power of 300 W with a minimum power gain of 20 dB and minimum drain efficiency of 60%. In Class-C operation at the same frequency, typical drain efficiency reaches 80%.
The device is chassis mount and uses gold metallization for excellent reliability. The package contains beryllium oxide (BeO) discs; safe handling is required if the discs are not damaged.
