While changing a motor I notice I had lost one of the diodes. It was missing. That motor stops more quickly but otherwise it appears to work ok. Not sure if I am wasting power or if the gate is being spiked with high voltage without the diode.

I found these on ebay will they do the job? Not 100% sure which bit of the code is which. I went for SOD-323 and BAT54 and this is what popped up.

5 X DIODE, SCHOTTKY, 40V, 300MA, SOD-323 Part # STMICROELECTRONICS BAT54JFILM.

It works without the diode but there might be a risk of damaging the MOSFET and generating more noise which could interfere with the radio.

That is the correct diode you are pointing at.

Thanks it worked fine. The two digit ident code was the same too. I didn't loose any so I have four spare.
