Product details

Pre-biased PNP switch — built-in resistors save board space

The Toshiba RN2402,LF is a PNP pre-biased transistor in a surface-mount S-Mini (SOT-23-3) package. It integrates two 10 kΩ resistors — one in series with the base (R1) and one between base and emitter (R2) — eliminating the need for external bias components in low-side switching and interface circuits. Collector-emitter breakdown is rated at 50 V, continuous collector current at 100 mA, and the transition frequency reaches 200 MHz.

50 V, 100 mA — where it fits the BOM

The 50 V VCEO and 100 mA Ic(max) cover most 12 V and 24 V logic-level loads: relay coils, small solenoids, LED strings, and level shifting. The 200 MHz fT means switching losses stay low well into the low-MHz range.

For a pre-biased PNP in the SOT-23-3 footprint, this part is a straightforward BOM line to qualify into production without obsolescence watch.

Frequently asked questions

What is the hFE (DC current gain) of RN2402 at 10 mA?

At 10 mA collector current and 5 V VCE, the minimum DC current gain (hFE) is 50. Typical gain will be higher, but the datasheet guarantees at least 50 at that bias point.

Is RN2402 equivalent to any other transistor?

The RN1417(TE85L,F) is a close functional peer — same 50 V, 100 mA rating and 0.2 W power dissipation, but it is an NPN pre-biased type with a 10 kΩ base resistor and 4.7 kΩ base-emitter resistor. The RN2402 is PNP, so polarity differs; they are not direct drop-in replacements.
