It is the PNP complement to the ubiquitous NPN 2N3904 / MMBT3904, rated for 40 V collector-emitter breakdown and 200 mA continuous collector current, with a transition frequency of 250 MHz. That means Infineon has scheduled the final production window — once that window closes, the part will not be manufactured again. If you have an active BOM line using this order code, you need to secure last-time-buy inventory or qualify a drop-in replacement before the cutoff. ## SOT-23-3 — what swaps in the field The package is TO-236-3 / SC-59 / SOT-23-3, with the supplier device package marked as PG-SOT23. It is a surface-mount part, so no lab bench needed for replacement if you have a fine-tipped iron and steady hands. The 330 mW power dissipation limit means it handles small-signal duty only — do not try to pull continuous load current near 200 mA without checking the thermal derating for your ambient.","metaTitle":"Infineon MMBT3906LT1HTSA1 PNP Transistor, 40 V, 200 mA","metaDescription":"Infineon MMBT3906LT1HTSA1 PNP general-purpose transistor, 40 V Vce, 200 mA Ic, 250 MHz fT, SOT-23-3 package.","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); Cut Tape (CT)","Power - Max":"330 mW","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Last Time Buy","Transistor Type":"PNP","lifecycle_stage":"eol_hot","Base Product Number":"MMBT3906","Operating Temperature":"150°C(TJ)","Frequency - Transition":"250MHz","Supplier Device Package":"PG-SOT23","Vce Saturation (Max) @ Ib, Ic":"400mV @ 5mA, 50mA","Current - Collector (Ic) (Max)":"200 mA","Current - Collector Cutoff (Max)":"50nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"100 @ 10mA, 1V","Voltage - Collector Emitter Breakdown (Max)":"40 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2684bbd1143ba9b8806e568b83f12c42.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MMBT3906LT1HTSA1/alternatives.json"},"ai":{"faq":[{"question":"Is MMBT3906LT1HTSA1 obsolete or end of life?","answer":"Yes, the MMBT3906LT1HTSA1 is in Last Buy status — it is end-of-life and will not be produced after the final order window closes.
