Part identification help :)
« on: October 23, 2017, 03:16:59 am »
Hey guys!

i need some help identifying an SMD component,

this is part of a PWM charging controller UC3843BN, when i check other components, i can see following with same 44

issue is, i've see few version of L44's, last 2 digits are different, above is L44 1/3 but I've seen L44 0/7 as well, since the burn part has the 7 on it.
the L44 marking mostly refer to BAT54S (PLANAR SCHOTTKY DIODES)

but what does the last 2 digits mean ?

The last 2 digits are probably the date code of when it was manufactured ..
