The 2.2 kOhm base resistor and 10 kOhm emitter-base resistor form a complete bias network inside the S-Mini SOT-23-3 package — no external resistors needed on the base leg. ## What the ratings mean on the bench 800 mA collector current and 200 mW max power mean this part drives small relays, solenoids, or indicator loads without a heatsink. The 200 MHz transition frequency is well above the switching speed of most relay coils or DC loads — the transistor stays in saturation during the on-time, not in the linear region where dissipation climbs. Vce saturation is 250 mV max at 50 mA collector current with 1 mA base drive — the on-state voltage drop is low enough that a 5 V logic rail driving the base through the internal 2.2 kOhm resistor will saturate the output cleanly. DC current gain minimum of 90 at 100 mA and 1 Vce means the transistor has enough beta to stay saturated with modest base current from a microcontroller GPIO pin.","metaTitle":"Toshiba RN2427TE85LF PNP Pre-Biased, 800 mA, S-Mini","metaDescription":"Toshiba RN2427TE85LF PNP pre-biased transistor, 50 V VCEO, 800 mA Ic, 200 mW, S-Mini SOT-23-3.
