The onsemi SMMBT2907ALT1G is a general-purpose PNP bipolar transistor designed for linear amplification and switching applications. It is housed in a compact SOT-23 / TO-236AB surface-mount package. The S-prefix version is intended for automotive and other applications requiring special site and change-control requirements, and is AEC-Q101 qualified and PPAP capable.
The transistor is rated for 60V collector-emitter voltage, 60V collector-base voltage, and 5V emitter-base voltage. Maximum continuous collector current is 600mA, while peak collector current is 1.2A.
DC current gain is specified at 100 minimum at 1mA, 10mA, and 150mA collector current, with a maximum of 300 at 150mA. At 500mA collector current, hFE remains at least 50 under the specified test condition.
Maximum collector-emitter saturation voltage is 0.4V at 150mA and 1.6V at 500mA under the specified forced-beta conditions. The device offers a 200MHz minimum transition frequency, 8pF maximum output capacitance, 45ns maximum turn-on time, and 100ns maximum turn-off time.
Power dissipation depends on the mounting condition: the datasheet specifies 225mW on an FR-5 board, 300mW on an alumina substrate, and up to 350mW with the specified heat-spreader condition. Junction and storage temperatures range from -55°C to +150°C. The exact SMMBT2907ALT1G is supplied in 3,000-piece tape-and-reel packaging, is MSL Level 1, and is currently listed by onsemi as Active.
