The 600 mA continuous collector rating sets the steady-state load ceiling; for inductive loads like relays or solenoids, derate to roughly 400 mA to keep the junction below 150°C in a 85°C ambient under the SOT-23 package's thermal resistance. At 500 mA collector current the Vce saturation is 1.6 V maximum with 50 mA base drive — that 1.6 V drop at 500 mA means 800 mW dissipation, which exceeds the 330 mW package limit in continuous operation. For saturated switching above 300 mA, either increase the base drive to lower Vce(sat) or limit the duty cycle to stay within the power budget. ## Gain floor for base-drive calculation The DC current gain (hFE) is guaranteed minimum 100 at 150 mA collector current and 10 V Vce. For a 150 mA load, the base drive needs at least 1.5 mA to guarantee saturation (assuming forced beta of 10). At lower collector voltages (e.g., 1 V to 2 V in deep saturation) the gain drops significantly — the datasheet's typical curves show hFE falling below 50 at Vce = 1 V, so the base drive should be sized for the saturated condition, not the 10 V test point. The 'T1' suffix indicates a specific lead-frame finish variant (tin-plated), and the 'XT' suffix denotes a bulk-pack option — both are current production codes.","metaTitle":"MMBT2907ALT1XT PNP Transistor, 60 V, 600 mA, AEC-Q101","metaDescription":"MMBT2907ALT1XT PNP transistor, 60 V Vce, 600 mA Ic, 200 MHz ft, AEC-Q101 automotive qualified, SOT-23 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"Automotive, AEC-Q101","Package":"Bulk","Power - Max":"330 mW","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","Transistor Type":"PNP","lifecycle_stage":"eol_hot","Operating Temperature":"150°C(TJ)","Frequency - Transition":"200MHz","Supplier Device Package":"PG-SOT23","Vce Saturation (Max) @ Ib, Ic":"1.6V @ 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)":"60 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/790fb154dab81a85ae677eca826417c5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MMBT2907ALT1XT/alternatives.json"},"ai":{"faq":[{"question":"What is the Vce saturation of MMBT2907ALT1XT?","answer":"The Vce saturation is 1.6 V maximum at 500 mA collector current with 50 mA base drive.
