Powersem 3-phase rectifier module 38A / 1600V
equivalent to PSD35-06, PSD35-08, PSD35-12 and PSD35-14. Often used as a drop in replacement of the discontinued IXYS VUO35-16NO7.
The difference between PSD35-16 and PSD35T-16 is the diode chip inside of the rectifier module. "T" is the new type which is still in production. PSD35 was its predecessor and was technically identical to VUO35. That version is out of production meanwhile.
