Procurement Notes

Verify the specific suffix (e.g., LF, TR) against the manufacturer's official datasheet to confirm packaging type and RoHS compliance status. Ensure the ordering part number matches the required tape-and-reel or cut-tape configuration. Confirm availability through authorized distributors as stock levels fluctuate. Cross-reference the manufacturer part number with equivalent listings to avoid counterfeit components.

Selection Notes

Select this component when a single NPN digital transistor with 50V rating and 100mA current capacity is required. The internal 4.7k/47k resistor network suits standard logic interface applications. Compare transition frequency and saturation voltage requirements against alternative models in the RN series. Ensure the SC-70 package footprint aligns with the PCB layout constraints.

Part Context

The RN1307,LF belongs to Toshiba's digital transistor family, which combines bipolar transistors with integrated bias resistors. This series is designed to replace discrete resistor-transistor combinations, reducing board space and assembly costs. It complements other devices in the RN series, offering standardized electrical characteristics for general-purpose switching tasks.
