It integrates two 47 kOhm resistors — one in series with the base (R1) and one between base and emitter (R2) — which eliminates the need for external bias resistors in switching and driver circuits. With a collector-emitter breakdown voltage of 50 V and a continuous collector current rating of 100 mA, it is suited for low-power switching in industrial controls, relay drivers, and logic-level interface stages where board space is tight. ## Last Buy status — plan your final order The BCR198E6433HTMA1 carries a Last Buy lifecycle status. For new designs or long-running production, a pin-compatible second source or substitution should be qualified now. ## 200 mW power limit — what it drives in the layout The maximum power dissipation of 200 mW sets the thermal budget. In a SOT-23 package without an exposed pad, this limits continuous collector current at elevated ambient temperatures. For a 10 mA load with a 300 mV Vce(sat), dissipation is only 3 mW, leaving ample headroom. But if the part is used near its 100 mA peak, duty cycle and ambient temperature must be derated — the 200 mW ceiling governs the safe operating area more than the current rating alone.","metaTitle":"Infineon BCR198E6433HTMA1 PNP Pre-Biased Transistor, 50 V","metaDescription":"Infineon BCR198E6433HTMA1 PNP pre-biased transistor, 50 V VCEO, 100 mA IC, 47 kOhm bias resistors, 190 MHz fT.
