This built-in bias network reduces external component count in switching and interface applications where a single transistor with known turn-on characteristics is needed. ## Last Buy — plan the BOM transition Infineon has placed the BCR135WH6327XTSA1 into Last Buy status. This means the factory has a final order window; after that date, new-issue supply will come only from the independent surplus and broker channel. For a production BOM that depends on this exact order code, the sourcing strategy needs to secure the last-time-buy quantity or qualify a replacement before the window closes. ## Ratings that matter for the design The 50 V collector-emitter breakdown voltage and 100 mA maximum collector current cover low-side switching, level shifting, and signal gating in 3.3 V to 24 V logic and industrial control circuits. The 150 MHz transition frequency means it switches cleanly at moderate speeds — suitable for GPIO-driven loads and low-frequency PWM, not for RF output stages. The 250 mW power dissipation limit in the SOT-323 package is the thermal ceiling: at 5 V and 10 mA the junction stays well within the safe area, but driving a 100 mA load near the Vce saturation voltage of 300 mV at 500 µA base current needs a check against the derating curve.","metaTitle":"Infineon BCR135WH6327XTSA1 NPN Pre-Biased Transistor","metaDescription":"Infineon BCR135WH6327XTSA1 NPN pre-biased transistor, 50 V, 100 mA, 150 MHz fT, SC-70/SOT-323.","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":"BCR135","Resistor - Base (R1)":"10 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":"$0.0501","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/393aee626b2da6d96af91aaeea0af3f8.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BCR135WH6327XTSA1 obsolete?","answer":"Infineon has designated the BCR135WH6327XTSA1 as Last Buy, which is the final phase before discontinuation.
