THYRISTOR,Part No: T1503N80T-S34.

1. Basic information:
Device type: Light Triggered PCT Thyristor (formerly EUPEC Upac product line, now Infineon);
Brand: Infineon (Infineon, originally from Germany);
Packaging: Circular ceramic pressure bonded disc, diameter 150mm, thickness 40mm (DO-200AE standard packaging);
Suffix description: T=Light triggered type; The suffix ‘934’ is for original factory process/packaging matching, and the electrical core parameters are consistent with the T1503N80TOH reference model.
2. Temperature and thermal performance:
Junction temperature range: -40 ℃~+120 ℃ (maximum allowable junction temperature Tjmax=120 ℃);
Storage temperature: -55 ℃~+175 ℃;
Shell junction thermal resistance Rth (jc): about 0.04K/W (large diameter flat plate has strong heat dissipation advantages)
3. Structure and triggering characteristics:
Fiber optic trigger: Built in laser receiving window, no need for high-voltage isolation gate drive, no EMI electromagnetic interference risk;
Equipped with an integrated protection diode to suppress reverse overvoltage;
Sealed ceramic all metal shell, earthquake resistant, water pressure resistant, and no risk of shell bursting;
Supporting accessories: Special trigger laser diode SPL-PL90A, matching fiber LWL R10-LR87
4. Typical application scenarios:
HVDC converter valve for high-voltage direct current transmission;
High power electrolytic rectification (electrolytic aluminum, chlor alkali chemical industry);
High voltage static reactive power compensation SVC/STATCOM;
High power industrial DC drive, intermediate frequency power supply;
Large capacity soft start and fault current limiting device for power grid
