Title: Marking code H1A sot-23
Post by: Johnny on 15 March 2016, 03:06:29

Hello friends,

I'm trying to a repair a satt board and have a faulty smd transistor marking code H1A
With Google search, I come to the SST4416 (SOT-23) [H1A]
But I have my doubts.

Possible that someone knows this transistor, or a replacement.
Thanks in advance.

Hello.
For some Chinese manufacturers:

H1A - MMBT3904
H2A - MMBT3906

Thanks for the great support,

It was a question of finding the MMBT3904 (marking code 7A with p, t or w) on my parts motherboards , but found him.
Placed and works as usual.

Thank you very much.
This SHD-8900 receiver is working good now.
