Technical Details & Description

Pre-biased NPN – what the integrated resistors save you

The Toshiba RN1417(TE85L,F) is an NPN pre-biased transistor in a three-pin S-Mini (SOT-23-3) surface-mount package. It integrates a 10 kΩ base resistor (R1) and a 4.7 kΩ emitter-base resistor (R2) on-chip, so you can drive the base directly from a logic output without adding external bias components. That cuts the placement count and shrinks the board area for high-density designs.

The 250 MHz transition frequency keeps switching edges clean for PWM up to a few megahertz. Saturation voltage is 300 mV at 5 mA collector current with 250 µA base drive, so the on-state loss stays low in saturated switching.

Toshiba lists the RN1417(TE85L,F) as Active with RoHS compliance.

Frequently asked questions

How does the RN1417(TE85L,F) compare to the RN1414?

Both are pre-biased NPN transistors in the same S-Mini package family. The RN1417 uses a 10 kΩ base resistor and 4.7 kΩ emitter-base resistor; the RN1414 uses different resistor values. Check the specific bias resistor ratio for your base-drive design — the RN1417 is suited for logic-level outputs that need a higher base current than the RN1414 provides.
