Philips BFQ135 NPN Transistor Datasheet
This document is a product specification datasheet for the Philips BFQ135, an NPN wideband transistor designed for frequencies up to 6.5 GHz. The device features emitter-ballasting resistors and gold sandwich metallization to ensure optimum temperature profiles and reliability. It is housed in a 4-lead dual-emitter SOT172A2 package with a ceramic cap.
The datasheet provides comprehensive electrical characteristics, including limiting values for voltage and current, thermal resistance data, and performance metrics such as transition frequency (fT) and maximum unilateral power gain (Gum). It also includes application information suggesting use in MATV and microwave amplifiers, radar systems, and oscilloscopes.
