Hi there,

I have a multimeter with a malfunction.

There are at least 2 problems.

PTC "152H"
NPN transistor "8050"

My questions are:

1. What does the "152H" marking code means on the PTC ?
2. Is there any known equivalent P/N for the 8050 transistor ?

May I have some help?

Thank you.

Michael.

I found the equ for the 8050 NPN.

Now my only problem is what the "152H" marking code means for the PTC.

Does anybody can help ?

Do you know the manufacturer of the device. Typically, each manufacturer has their own code and without the manufacturers key for that code, it's anybody's.

I typed PTC 152H into google and the first 4 hits looked good and the 5th hit was your message.

Thank you guys.

George, althought I have some samples of MMBT8050, I used a TH NPN (ZTX851).

I don't know the PTC manufacturer. The component is really burned and I just can see the marking code (I am lucky) which is 152H. It must be 1K5 Ohms.

Thank you all.
