The Toshiba RN1706,LF packs two NPN pre-biased transistors into a single 5-pin USV package (5-TSSOP / SC-70-5 / SOT-353). Each transistor integrates a 4.7 kΩ base resistor (R1) and a 47 kΩ emitter-base resistor (R2), eliminating the need for external biasing resistors in switching and inverter applications. The 250 MHz transition frequency keeps switching edges clean for signals up to a few megahertz.
Each of the two NPN pre-biased transistors has a base resistor (R1) of 4.7 kΩ and an emitter-base resistor (R2) of 47 kΩ. These are integrated on-chip, so no external bias resistors are needed.
The RN1706 and RN1705 are both dual NPN pre-biased transistors in the same USV package, but they differ in the integrated resistor values. The RN1706 uses a 4.7 kΩ base resistor and a 47 kΩ emitter-base resistor; the RN1705 uses different resistor values. Check the respective datasheets for the exact RN1705 resistor values.
