Product Overview
The MMBTA06 is an NPN bipolar junction transistor designed for general-purpose switching, driver, and small-signal amplification applications. It features an 80V collector-emitter voltage rating, 500mA maximum collector current, and a minimum DC current gain of 100 at 100mA collector current. Its combination of moderate voltage capability and low saturation voltage makes it suitable for compact control and interface circuits.
Packaged in a SOT-23 surface-mount package, the MMBTA06 is well suited to space-constrained PCB designs. It can be used in transistor driver stages, low-current load switching, signal amplification, and discrete control circuits where higher voltage capability than typical low-voltage small-signal BJTs is required.
