I have a SMD device that I am am trying to identify. S2 device

Can anyone point me to a manufacturer? Probably a resistor but I am not sure. Any help would be appreciated.

The scale bar in the picture is not correct

  • \$\begingroup\$ Can you get a DMM on diode mode on that thing? \$\endgroup\$ – Voltage Spike Jun 6 at 20:58
  • \$\begingroup\$ There are some varactor diodes in a similar looking package & marking. What's the function of the circuit? \$\endgroup\$ – Spehro Pefhany Jun 6 at 22:38
  • \$\begingroup\$ The circuit board is an LCD driver board. I always thought diodes had a polarity mark of some sort; I'll probe and do some tests. \$\endgroup\$ – Robert Tufts Jun 7 at 22:09
  • \$\begingroup\$ I suspect that vague dotted stripe on the left is intended to be the polarity marking... \$\endgroup\$ – brhans Jun 7 at 22:23

Taiwan Semiconductor makes a 1N4448 diode in a SOD-323F package with 'S2' marking.
Some accurate measurements on the package would help to confirm.

Thanks to all that responded it appears to be a huaban CMS02 M-FLAT Marking S2 Schottky Barrier Diode
