Our RIS-796 250-amp LED current pulser has been operated up to 1100A by Rob Legg, and is well suited to make shaped current pulses up to 750 amps. E.g., "8.3ms single half sine-wave" for "Peak forward surge current" diode testing. Manufacturers like to make rating plots for 1 to 100 cycles, etc. For example, a SMD or SMC diode I'm considering is rated at 350A for one cycle, dropping to 60A for 100 cycles. Fun stuff.
tab Faston connectors. These tabs are very well suited to fat-wire crimped plugs and cable "receptacles". They mount into 0.200- inch 5.08mm-spaced holes on the PCB, and I've been spacing adjacent tabs connectors 0.23 inches apart, to allow for easy handling of the huge crimp plug housings.
Ideally diode testing would be done with the candidate part properly mounted on a PCB, so it has the right thermal mass, etc., but I haven't found any PCB-mounting Faston plugs. Moreover, it's clear that adjacent PCB-mounted connectors need perfectly-accurate spacing, or they won't mate. This means forget Faston, and use 5.08mm PCB-mounting connectors. But, bottom-line, most RIS-796 applications will still need the Faston tabs mounted, but now at 0.20-inch rather than 0.23-inch spacing.
Looking at "yellow" AWG 10-12 crimp terminals, purchased at Home Depot, moving the Faston tabs 30-mils closer to each other, would only leave a roughly 10-mil plug-to-plug gap. So, can you help convince me that's enough?
