Title: Trying to identify two smd components
Post by: octavez on March 29, 2023, 01:48:26 am
Hi,

I'm trying to identify two smd components one SOD-323 diode (DE 9) and a SOT-23 transistor (1BW 19), photos attached.

My guess is the diode might be a zener.

Thank you in advance!

Octave

1WB = SOT-323    BC846BW   NXP   NPN transistor

BE 5 = TVS diode  ?

In SOD123 package with top marking DE：MMSZ4697T1G

Yes I think that's correct!

I think the package is SOD-323 (not SOD-123) and so it could be a BZX384-C16:

What do you think?

Thank you!

Sorry, I think you are wrong. Find a ruler and measure the size of it and you'll believe me.  :)

Sorry you were correct! MMSZ4697T1G it is!
