For the applications I have in mind the higher Ron value alone disqualifies the fake part instantly.

I bought these modules from Amazon to use in the tail light of my infiniti qx60 2017 damaged due to sloppy installation, which resulted in water flooding the leds and shorted it. I used a couple of 2.2v leds and power from this module. It has been a couple of yrs, and it is still working.

That's why when i'm shopping on aliexpress i search for the product i need and not by the IC. This tends to give more real results, because you're not searching for an product, but for an solution. If they sold it as a 1A output modulo would still be cheap and worth it, there's is no reason to lie. Well, capitalism in it's finest hahaha

I worked at HP/Agilent in the late 90's for the Semiconductor Test division in Santa Clara site as a firmware engineer. I worked on the Versatest V3300 tester and designed firmware to run the tester to create a 3D Schmoo plot code that ran the tester to characterize DUT... Those were good times!

Interesting! I bought 4 of these! I used one for charging my car battery! At the input of this module, I have a 220v-18v AC transformer followed by a 3amp bridge rectifier and 2x470 mfd capacitors. I run it at 2amps because of the overheating! I adjust it's output to 13.5 v needed by my car battery. I think it gives me peace of mind because of short circuit protection! And the fact it will stop charging automatically at peak car battery voltage!

Hoo lee Fuk, curve tracer that poops out complete data sheet. And I'm stuck with Tek 7CT1N and a Telequipment CT71... Went through the whole fake/useable process a while ago, too. Needed to repair/upgrade some welding machines. Only checked Rds and breakdown voltgage, Rds is easy with like Keithley 2010 and 5Amp power supply. Breakdown voltage was done wtth IM6 Megohmmeter, other parameters are mostly irrelevant for 500Hz DC/AC converter on a TIG machine.

I've soldered a bunch of 0201 PCBs for drones. It's quite boring and exhausting activity. According to my experience, I'd wouldn't use the tip like yours's one. Apply a constant pressure from top to the 0201 element. <1% boards were faulted. Fix your wrists on the table.

That's the Chinese amps. To get the real one, you need to divide them by 2 or 3. In some cases additional airflow or\and radiator is required. It's not perfect for mission critical stuff, but I never had any issues with this type of module.
