The base and emitter-base resistors are integrated on-chip — 22 kOhms (R1) and 47 kOhms (R2) — eliminating two external passives per switching node. Collector current is rated 100 mA maximum with a collector-emitter breakdown voltage of 50 V, making this part suitable for low-current load switching, relay drivers, and logic-level interface circuits where board area is tight. ## Last Buy — sourcing window is closing Infineon has placed the BCR142WH6327XTSA1 in Last Buy status. That means the manufacturer has announced a final production run; once that inventory is consumed, no further factory orders will be accepted. For a BOM line that depends on this exact order code, the procurement decision is time-sensitive — secure the required quantity before the last-time-buy window closes.","metaTitle":"BCR142WH6327XTSA1 NPN Pre-Biased Transistor, 100 mA, SC-70","metaDescription":"Infineon BCR142WH6327XTSA1 NPN pre-biased transistor in SC-70 (SOT-323). 100 mA Ic, 50 V Vce, 22 kΩ / 47 kΩ bias resistors.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Power - Max":"250 mW","Mounting Type":"Surface Mount","Package / Case":"SC-70, SOT-323","Product Status":"Last Time Buy","Transistor Type":"NPN - Pre-Biased","lifecycle_stage":"eol_hot","Base Product Number":"BCR142","Resistor - Base (R1)":"22 kOhms","Frequency - Transition":"150 MHz","Supplier Device Package":"PG-SOT323","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":"$0.0618","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/15916323a0294a8799b1bb4314e88a75.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BCR142WH6327XTSA1 obsolete?","answer":"Infineon lists the BCR142WH6327XTSA1 as Last Buy, meaning it is in the final production phase and will become obsolete once the last-time-buy inventory is depleted. It is not yet fully discontinued, but the end-of-life process has begun."},{"question":"What is the replacement for BCR142WH6327XTSA1?","answer":"A pin-compatible alternative would need to be selected from the same pre-biased NPN transistor family with matching 22 kOhms base and 47 kOhms emitter-base resistor values, such as the BCR141WH6327XTSA1 (which uses different resistor ratios). Validate the resistor divider and package footprint before substituting."},{"question":"What is the maximum collector current for BCR142WH6327XTSA1?","answer":"The maximum collector current (Ic) is 100 mA. This is the continuous current rating; for pulsed or high-duty-cycle applications, refer to the power dissipation limit of 250 mW and the thermal characteristics of the SC-70 package."},{"question":"What is the difference between BCR142WH6327XTSA1 and BCR141WH6327XTSA1?","answer":"Both are NPN pre-biased transistors in SC-70 packages, but the BCR142 uses a 22 kOhms base resistor (R1) and 47 kOhms emitter-base resistor (R2), while the BCR141 uses different resistor values. The resistor ratio determines the input threshold and saturation drive — check your base-drive requirements before swapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BCR142WH6327XTSA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BCR142WH6327XTSA1 when reusing this data.
