MMBT2907ALT1G

MMBT2907ALT1G is an onsemi PNP general-purpose transistor in a SOT-23 package, rated at 60 V collector-emitter voltage and 600 mA collector current, with hFE of 100 to 300 and a transition frequency of 200 MHz — the surface-mount 2N2907A-class device for high-side switching, driver stages and complementary pairs in industrial and consumer boards. onsemi's product page lists this exact code as Active. Selection advice: this is the natural complement to the NPN MMBT2222ALT1G also listed here — designing a push-pull or driver stage around the matched pair keeps one vendor's gain and saturation documentation across both halves of the circuit. As with every SOT-23 BJT, the 600 mA figure is a maximum rating, not a continuous design target: check saturation voltage and package dissipation at your actual operating point, and quote the full LT1G code, since the G suffix is the lead-free tape-and-reel ordering form and the non-G base code is not the current orderable. Parameters verified against onsemi documentation.
