BLF145 HF power MOS transistor Rev. 04 5 January 2007 Product data sheet IMPORTANT NOTICE Dear customer, As from October 1st, 2006 Philips Semiconductors has a new trade name - NXP Semiconductors, which will be used in future data sheets together with new contact details. In data sheets where the previous Philips references remain, please use the new links as shown below. NXP Semiconductors Product specication HF power MOS transistor BLF145 FEATURES PIN CONFIGURATION High power gain Low noise figure handbook, halfpage Good thermal stability 1 4 Withstands full load mismatch. d DESCRIPTION g Silicon N-channel enhancement s MBB072 mode vertical D-MOS transistor designed for SSB transmitter 23 applications in the HF frequency range. The transistor is encapsulated MSB057 in a 4-lead, SOT123A flange package, with a ceramic cap. All Fig.1 Simplified outline and symbol. leads are isolated from the flange. Matched gate-source voltage (V ) GS groups are available on request. CAUTION This product is supplied in anti-static packing to prevent damage caused by PINNING - SOT123A electrostatic discharge during transport and handling. For further information, PIN DESCRIPTION refer to Philips specs.: SNW-EQ-608, SNW-FQ-302A, and SNW-FQ-302B. 1 drain 2 source WARNING 3 gate Product and environmental safety - toxic materials 4 source This product contains beryllium oxide.
