Power dissipation is limited to 200 mW total — in a 25 °C ambient the US6 package's thermal resistance means each transistor should stay below 100 mW continuous when both are on simultaneously, or the junction temperature climbs past the safe operating area. ## What the 10 kOhm base resistor means for the BOM The 10 kOhm R1 sets the base current when the drive voltage is applied — at 5 V logic, the base sees roughly (5 V - 0.7 V) / 10 kOhm ≈ 430 µA, which with a minimum hFE of 80 supports a collector current of about 34 mA, well within the 100 mA rating. The 47 kOhm R2 across base-emitter provides a guaranteed off-state: with the drive at 0 V, the resistor pulls the base to emitter, keeping collector cutoff below 500 nA — critical for preventing leakage-driven loads in battery-powered or high-impedance circuits.","metaTitle":"Toshiba RN2907,LF(CT Dual PNP Pre-Biased, 10k/47k","metaDescription":"Toshiba RN2907,LF(CT dual PNP pre-biased transistor, 50V, 100mA, 200mW, US6 package, active production, ROHS3.

Both share the same 47 kOhm base-emitter resistor (R2), 50 V rating, 100 mA collector current, and US6 package. The higher R1 in the RN2907 draws less base current from the drive source, suiting it for lower-drive logic outputs."},{"question":"What is the closest functional second-source to RN2907,LF(CT?","answer":"The RN2967(TE85L,F) is functionally equivalent — same dual PNP pre-biased topology, same 10 kOhm / 47 kOhm resistor divider, same 50 V / 100 mA ratings and US6 footprint.
