It integrates two 47 kΩ resistors — one in series with the base (R1), one from base to emitter (R2) — so you can drive it directly from a logic output without external bias components. The 50 V collector-emitter breakdown and 100 mA collector current rating suit low-power switching loads like relay drivers, LED indicators, or level shifters in industrial and consumer boards. The 190 MHz transition frequency gives it enough bandwidth for moderate-speed switching up to a few megahertz. ## 50 V / 100 mA — sizing the switching load With a VCE(max) of 50 V and IC(max) of 100 mA, this transistor handles typical 12 V or 24 V relay coils, small solenoids, and indicator LEDs. The saturation voltage is 300 mV at 500 µA base current and 10 mA collector current, so it stays cool in lightly loaded switching. For loads above 80 mA, check the power dissipation ceiling of 200 mW — at 50 V and 100 mA you'd exceed that, so derate the current or voltage accordingly. ## Obsolete — sourcing reality Infineon lists the BCR198B6327HTLA1 as obsolete. If you are designing a new board, look at current Infineon pre-biased PNP families in SOT-23 with similar resistor values; the pinout is standard across the series, so a drop-in replacement may exist with a different base resistor ratio.","metaTitle":"BCR198B6327HTLA1 PNP Pre-Biased Transistor, 50 V, 100 mA","metaDescription":"Infineon BCR198B6327HTLA1 PNP pre-biased transistor, 50 V VCEO, 100 mA IC, 190 MHz fT, PG-SOT23 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Power - Max":"200 mW","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Obsolete","Transistor Type":"PNP - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR198","Resistor - Base (R1)":"47 kOhms","Frequency - Transition":"190 MHz","Supplier Device Package":"PG-SOT23","Resistor - Emitter Base (R2)":"47 kOhms","Vce Saturation (Max) @ Ib, Ic":"300mV @ 500µA, 10mA","Current - Collector (Ic) (Max)":"100 mA","Current - Collector Cutoff (Max)":"100nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"70 @ 5mA, 5V","Voltage - Collector Emitter Breakdown (Max)":"50 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a076d8f34ecd766117d4342d668fd756.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BCR198B6327HTLA1?","answer":"The BCR198 family shares a standard SOT-23 pinout with other Infineon pre-biased PNP types.
