The SOT-883 (PG-TSLP-3-4) package handles collector currents up to 100 mA and blocks 50 V, with a transition frequency of 150 MHz. ## Active production — no obsolescence headache Infineon lists the BCR 135L3 as Active. ## Package and mounting Saturation voltage is specified at 300 mV maximum with 500 µA base current and 10 mA collector current — well within the Vce(sat) budget for a typical low-side switch driving a relay coil or an LED string. The 100 nA collector cutoff keeps leakage negligible at high temperature, which matters if the load is a high-impedance input.","metaTitle":"Infineon BCR 135L3 E6327 NPN Pre-Biased Transistor, 150 MHz","metaDescription":"Infineon BCR 135L3 E6327 NPN pre-biased transistor, 50 V, 100 mA, 150 MHz, 10 kΩ base resistor, 47 kΩ emitter-base resistor, SOT-883 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Power - Max":"250 mW","Mounting Type":"Surface Mount","Package / Case":"SC-101, SOT-883","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR 135","Resistor - Base (R1)":"10 kOhms","Frequency - Transition":"150 MHz","Supplier Device Package":"PG-TSLP-3-4","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://www.infineon.com/dgdl/Infineon-BCR135SERIES-DS-v01_01-en.pdf?fileId=db3a30431428a37301143f8b054a0289","sourceUrl":null},"ai":{"faq":[{"question":"Can BCR 135L3 replace BC848?","answer":"Not directly — the BC848 is a standard NPN transistor with no internal bias resistors. The BCR 135L3 includes a 10 kΩ base resistor and a 47 kΩ emitter-base resistor, so the circuit would need to be designed for those bias conditions. If the original design used external resistors, the BCR 135L3 can replace the BC848 plus those two passives, saving board space."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR-135L3-E6327","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR-135L3-E6327 when reusing this data.
