Its 1.8 kV off-state voltage and 844 A average on-state current place it squarely in medium-voltage motor drives, large UPS bypass switches, and DC power supplies that need a press-pack or stud-style chassis-mount device. The 1500 A RMS rating is the continuous current the bus bar and heatsink must carry; the 14500 A non-repetitive surge at 50 Hz drives fuse sizing and fault coordination — the SCR must survive the clearing time of the upstream semiconductor fuse. The package is DO-200AB, B-PUK, a ceramic-housed, stud-base chassis-mount package common in high-power thyristor assemblies. Chassis mounting means the thermal path goes through the base into a heatsink or cold plate — no PCB footprint, no soldering. ## Gate drive and trigger requirements The gate trigger voltage maximum is 1.5 V, and the gate trigger current maximum is 250 mA. That is a substantial gate drive — a standard 5 V logic-level pulse from a microcontroller or small-signal transistor will not reliably turn this SCR on. A dedicated pulse transformer or isolated gate driver with a 1 A peak capability is typical. The hold current of 300 mA means the SCR will drop out of conduction if the load current falls below that threshold; in a phase-control circuit with a highly inductive load, the commutation margin needs checking against this value. The T830N12TOFXPSA1 is marked obsolete. If your design is still in the prototype or pre-production phase, evaluating a current-production SCR from the same voltage and current class is the lower-risk path for a new build.","metaTitle":"T830N12TOFXPSA1 SCR, 1.8 kV 844 A, DO-200AB","metaDescription":"T830N12TOFXPSA1 single SCR rated 1.8 kV off-state, 844 A average, 1500 A RMS.
