MBT3946DW1T1
The MBT3904DW1T1, MBT3906DW1T1, and MBT3946DW1T1 devices are
spinoffs of our popular SOT23/SOT323 threeleaded devices. They are designed
for general purpose amplifier applications and are housed in the SOT363 sixleaded
surface mount package. By putting two discrete devices in one package, these devices
are ideal for lowpower surface mount applications where board space is at a premium.
