This eliminates two external resistor pairs per channel, shrinking the footprint for level translation, driver, or inverter stages on dense PCBs. Each transistor is rated for 50 V collector-emitter breakdown and 100 mA continuous collector current, with a total package dissipation of 100 mW. The 250 MHz transition frequency supports switching up to low-MHz range in logic-level interface or relay driver circuits. ## Active lifecycle and RoHS3 compliance The supplier device package is designated ES6. ## Bias resistor network and saturation performance Both R1 (base resistor) and R2 (base-emitter resistor) are 22 kOhms, giving a fixed input threshold that turns the transistor fully on at standard logic levels without external biasing. Collector cutoff current is 100 nA maximum, which keeps off-state leakage below the threshold for high-impedance inputs.","metaTitle":"Toshiba RN4983FE,LF(CT Dual Pre-Biased Transistor, 100mW","metaDescription":"Toshiba RN4983FE,LF(CT dual NPN/PNP pre-biased transistor in SOT-563. 50V Vce, 100mA Ic, 250MHz ft.
