Varo Iso Press-fit 25 Amp 200 Piv Fast Recovery Dual Rectifiers, Nos, Lot Of 4

A lot of 4 NOS VARO dual rectifiers still packed in the original sample packs (2). Type No. VYB200X  common anode configuration, BLACK dot is negative (anodes).  (NOTE --this is opposite my other VY series listings.) 25 A, 200 PIV, 200 ns recovery (fast). Press-fit mounting w/2000 Volt max. isolation between circuit (rectifiers) and case. R(th) 1 deg. C/Watt Junction to case. Full datasheet can be found online. These are the basic VY series press-fit units, mounting hole and press-fit technique must follow manufacture's instructions.  Electrical terminals are 3/16" appliance tab (male) terminals.  At this current level (25 A) I would not recommend 3/16" female mating terminals, BUT if  you want to try it, do the following: Polish the terminals (Dremel job), coat terminals with a light coal of full synthetic oil and use only T & B folded (long spring arm) female terminals.  A sample of the T & B design (in a 1/4" terminal) will be provided.  Use 10 or  12  gauge stranded wire for low loss, flexibility and as a terminal heatsink.  Heatsink the diode and test the terminal loss with (say) 20 Amps DC.  Use sharp probes and a millivolt reading meter.  Terminal losses must be small (say less than 1/10 th) with respect to the diode forward loss (1 diode).   Push-on terminals will reduce the terminal to case clearance -- gap likely too small for 2000 V. My item #213
