The built-in resistors eliminate the need for external base bias components, saving board space in high-density designs. Each transistor is rated for 50 V collector-emitter breakdown and 100 mA continuous collector current, with a maximum power dissipation of 300 mW for the dual device. The 200 MHz transition frequency supports switching applications up to low-MHz range. ## Bias resistor ratio sets the switching threshold With R1 = R2 = 10 kΩ, the input threshold voltage at the base is approximately half the supply voltage — the transistor turns on when the input exceeds Vbe(on) plus the voltage drop across R2. This symmetrical ratio is commonly used in inverter and logic-level interface circuits where a clean on/off transition is needed without external resistor dividers. The DC current gain is specified at a minimum of 50 at Ic = 10 mA, Vce = 5 V. Saturation voltage is 300 mV maximum at Ib = 250 µA, Ic = 5 mA — the internal resistors supply enough base drive to saturate the transistor at moderate collector currents.","metaTitle":"Toshiba RN2502(TE85L,F) dual PNP pre-biased transistor","metaDescription":"Toshiba RN2502(TE85L,F) dual PNP pre-biased transistor, 50V Vce, 100mA Ic, 300mW, SC-74A (SMV).

The difference is the emitter-base resistor (R2): RN2502 uses 10 kΩ, while RN2507 uses 47 kΩ. This changes the input threshold voltage — RN2502 switches at a lower input voltage than RN2507.
