USB Mains Charger - schottky equivalent?

[gregmcc]

I've got a USB mains (100-240VAC) travel charger (Model ST-099A20) that has stopped working.

I've opened it up and traced it down to a faulty shottky diode. Or at least I think it's a schottky diode from the info I can find.

Its the 2 black SMD diodes by the white paste in the pic. I've removed them and one of them is shorted.
On the diode is
JF
SS36

From the info I can find here:
https://www.electro-tech-online.com/custompdfs/2013/01/88751.pdf

Its Maximum repetitive peak reverse voltage = 60V
Maximum RMS voltage = 42V
Maximum DC blocking voltage = 60V
Maximum average forward rectified current = 3A
Peak forward surge current 8.3 ms single half sine-wave superimposed on rated load = 100A

I've checked out the local electronics shop and cant find the same smd device.

My question is can I use something like a 1N5822 in its place?

Max. Recurring Peak Reverse Voltage: 40V
Max. RMS Voltage: 28V
Max. DC Blocking Voltage: 40V
Max. Average Forward Rectified Current at 95°C: 3A
Max. Instantaneous Forward Voltage at 3A DC: 0.525V
Max. Forward Voltage at 9.4A: 0.95V
Max. Average Reverse Current at 40V DC: 2mA

If this is not suitable, can someone please recommend something I could use. It doesnt have to be a SMD.

What is the ouput current rating of that charger?

 

[gregmcc]

5V, 2 Amps

I would guess the 3A rating of the 1N5822 makes it a suitable candidate (even if the voltage rating isn't as high as the original).

Great - thanks. I'll try that and see how it goes.

Update: 1N5822 works like a bomb. As good as new
