Product Overview
The MMBT5401 is a PNP bipolar junction transistor designed for high-voltage switching and small-signal amplification. It features a 150V collector-emitter voltage rating, 600mA maximum collector current, and a minimum DC current gain of 60 at 10mA collector current. Its relatively high voltage capability makes it suitable for discrete analog, level-shifting, and control circuits that operate above the range of typical low-voltage PNP transistors.
Packaged in a compact SOT-23 surface-mount package, the MMBT5401 is well suited to space-constrained PCB designs. Its 300MHz transition frequency also supports signal amplification, interface stages, and complementary transistor circuits requiring both higher voltage tolerance and small package size.
