It handles a collector current up to 600 mA with a collector-emitter breakdown voltage of 40 V, and switches at a transition frequency of 300 MHz. Typical applications include low-power switching, driver stages, and signal amplification in industrial controls, consumer electronics, and telecom modules where board space is tight. The 600 mA collector current rating covers most small-signal switching and driver needs, but it is not a power transistor — the 330 mW power dissipation limit means the junction temperature climbs fast above 150 mA continuous in a SOT-23 at 25°C ambient. For loads over 200 mA, check the thermal derating. The 300 MHz transition frequency is fine for switching up to a few megahertz; for higher-speed logic-level translation, look at a dedicated level shifter. The saturation voltage is 1 V maximum at 50 mA base current and 500 mA collector current — budget that drop when calculating the on-state voltage in a switching circuit. ## Last Buy — what it means for procurement If you have an existing BOM that uses this transistor, now is the time to secure your last order or qualify a pin-compatible replacement. We source it through independent distribution and can quote current availability against an RFQ.","metaTitle":"Infineon MMBT2222ALT1HTSA1 NPN Transistor, 600 mA, 40 V","metaDescription":"Infineon MMBT2222ALT1HTSA1 NPN switching transistor: 600 mA Ic, 40 V Vce, 300 MHz ft, SOT-23.","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":"NPN","lifecycle_stage":"eol_hot","Base Product Number":"MBT2222A","Operating Temperature":"150°C(TJ)","Frequency - Transition":"300MHz","Supplier Device Package":"PG-SOT23","Vce Saturation (Max) @ Ib, Ic":"1V @ 50mA, 500mA","Current - Collector (Ic) (Max)":"600 mA","Current - Collector Cutoff (Max)":"10nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"100 @ 150mA, 10V","Voltage - Collector Emitter Breakdown (Max)":"40 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3687a05c1c57e42dedf924e6c22a9825.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MMBT2222ALT1HTSA1/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy MMBT2222ALT1HTSA1?","answer":"Submit a request for current pricing and availability — we confirm both at quote time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/MMBT2222ALT1HTSA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/MMBT2222ALT1HTSA1 when reusing this data.
