Product Overview
The MMBT2907 is a PNP bipolar junction transistor designed for general-purpose switching and amplification. It features a 40V collector-emitter voltage rating, 800mA maximum collector current, and a minimum DC current gain of 100 at 150mA collector current. Its moderate current capability makes it suitable for low-voltage load switching, driver stages, and complementary transistor circuits.
Packaged in a compact SOT-23 surface-mount package, the MMBT2907 is well suited to space-constrained PCB designs. It can be used in PNP high-side switching, signal amplification, LED control, and other low-power discrete control applications.
