Trying to figure out what this is, and suitable replacements. Markings are "1 Wt 77" Cannot seem to find anything.

enter image description here

Edit: I removed and sized it today, looks like 2.04 mm square package, exactly like the one on the below spec sheet... but not that part. Still cannot find those markings...

SiA936EDJ (not a 1Wt)

  • \$\begingroup\$ Hmm, 1Wt = SOT-323 Philips (NXP) BF822W NPN transistor. Is that a SOT-6 package? \$\endgroup\$

  • \$\begingroup\$ Hi thank you! it's smaller than the SOT-6 package size... from what I can tell it's closer to this package size: 6-WDFN \$\endgroup\$

  • \$\begingroup\$ It was 6 pins and I believe is a dual fet chip... not sure if its dual N, dual P or N and P though... \$\endgroup\$

  • \$\begingroup\$ Hmm, could it be a SOT-666 package? May have to measure it. \$\endgroup\$
