The standard NPN BJT in SOT-23 package has the following arrangement of pins:

enter image description here

Do you know of any transistor that has pins 1 and 2 reversed? So that 2 is the base while 1 is the emitter (Doesn't matter if NPN or PNP, i.e. Emitter or Collector). I truly can't seem to find such a device.

    \$\begingroup\$ If you are doing manual soldering for a one-off, you could solder it on upside down. \$\endgroup\$ May 2 '17 at 18:45

    \$\begingroup\$ Because I failed at routing and the PCB is already on its way. Also it would look cleaner than soldering upside-down. Just a nitpick. \$\endgroup\$

    \$\begingroup\$ Upside down with bent over pins is hardly distinguishable. Just ask any of my customers that I gave any of my early prototypes from the period 1996 to 2003. (Libraries and being paid well for the time started making a difference at that point). Other than that, there are plenty such, just not as plenty plenty plenty as there are that are as your picture. \$\endgroup\$

  • \$\begingroup\$ Well thanks, I will try the upside down package then :) \$\endgroup\$

the order code typically has a suffix R for Reverse

bc847 and bc847R emitter base swapped.
