Description

The T508N is a silicon mains frequency thyristor made by IPRS Băneasa [1].

The I.P.R.S. Băneasa Full Line Condensed Catalog (1990) lists the T508N400…T508N1800 (9 codes) among the „Mains frequency thyristors ( ITAVM > 100 A )” of its „Thyristors” section [1]. Their values are under Variants [1]. In this table VT (at the IT given), ID = IR, IGT and VGT are maximum values, tq is a maximum, i²t is printed in kA²s and IT in kA, dv/dt is given with the footnote „Different dv/dt groups: C = 400, F = 1000 V/µs” and RthJ-C = 0.053 °C/W [1].
