Dual pre-biased NPN in SOT-553
The Toshiba RN1710JE(TE85L,F) integrates two NPN transistors with internal bias resistors in a single SOT-553 package, each with a base resistor of 4.7 kΩ. The emitter-coupled pair shares a common emitter node, simplifying layout for differential or cascode stages where two matched transistors are needed.
250 MHz transition frequency
With a transition frequency of 250 MHz, this part can handle fast switching in signal conditioning, level translation, or oscillator circuits. The integrated bias resistors eliminate two external resistors per transistor, cutting BOM count and board area.
