It is a B-graded variant of the BC846 family, meaning the DC current gain is specified with a minimum hFE of 200 at 2 mA collector current and 5 V VCE — tighter and higher than the A-grade floor. Collector-emitter breakdown is rated at 65 V, maximum collector current 100 mA, and power dissipation 330 mW, which covers general-purpose switching and amplifier duty in low-power analog and digital circuits. This part carries an obsolete product status. Infineon no longer manufactures the BC 846B as a current-production line item. For a BOM that needs this exact order code, the supply channel is independent distribution — surplus, new-old-stock, or broker inventory. ## 250 MHz transition frequency — switching and bandwidth With a transition frequency of 250 MHz, the BC 846B can handle moderate-speed switching up into the low VHF range. It is not a high-speed RF transistor, but it will comfortably switch at a few megahertz or amplify audio and low-frequency signals without gain roll-off concerns. ## VCE(sat) and cutoff — drive margin and leakage Saturation voltage is specified at 600 mV maximum with a 5 mA base drive into 100 mA collector current — a typical ratio for a general-purpose NPN. Collector cutoff current is 15 nA maximum (ICBO), which is low enough for battery-powered circuits where off-state leakage matters.","metaTitle":"BC 846B E6327 NPN Transistor, 65 V, 100 mA, SOT-23","metaDescription":"Infineon BC 846B E6327 NPN general-purpose transistor, 65 V VCEO, 100 mA Ic, hFE 200 min, 250 MHz fT, SOT-23.

The B grade is preferred when you need consistent gain across a production batch for analog bias or current mirror circuits."},{"question":"What is the replacement for BC 846B E6327?","answer":"Infineon does not list a direct successor for this order code. A functionally equivalent NPN in SOT-23 with similar ratings (65 V, 100 mA, hFE ≥ 200) would be the BC846B from other manufacturers — verify pin compatibility and gain grade before substituting. For a drop-in from Infineon, check the BC 847B or BC 848B series if the voltage rating allows."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BC-846B-E6327","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BC-846B-E6327 when reusing this data.
