Re: Humax sat receiver HDR - 1100S Help identify part.
Thanks for your reply R J
I found AP133 in DFN2020-6 package but its for 2v to 6v
I need for 12v.
I emailed Diodes to see if they have any alternative for me.
Thanks...

Re: Humax sat receiver HDR - 1100S Help identify part.
Thanks very much for your reply.
This receiver has two of them on the circuit board, same number (PT5RA) on the board marked as U4304 and U4305
I removed U4305 because I shorted pin 1 with pin 2 and it burned hole in it.
On U4305 (removed) voltage is:
Pin1 0.092v
Pin2 12v
Pin3 3.37v
Pin4 about 0.500v when starting measuring voltage drops to 0v
Pin5 Groung
Pin6. 0.035v
On the U4304 (second one on the board)
Pin1 3.51v
Pin2 12v...Last edited by Dumar84; 02-17-2022, 04:47 PM.Leave a comment:

Anyone know what this is, is this some sort of MOSFET?

Humax sat receiver HDR - 1100S Help identify part.
Hello, Im trying myself in electronics repair, with zero knowledge :-)
I have Humax sat receiver HDR - 1100S it won't power on. I found short on part ML5ED been advised that it was dc dc converter SY8113 (ordered on AliExpress and waiting for delivery)
And when been measuring voltages on the board I shorted contacts in another part �� and hoping someone will help me to identify that part. PT5RA its 2mm x 2mm size
