Note on data consistency. The dominant technical identity of the 5SHY35L4510 across datasheet-aggregator and component-supply sources is an asymmetric IGCT with a 4500 V blocking voltage class, RMS on-state current in the ~2670 A range, and a 4000 A snubberless turn-off rating. Two notable inconsistencies appear in secondary listings: (1) one reseller page describes the part as a symmetric IGCT with 3500 V bidirectional blocking and 4500 A continuous current, values that conflict with the asymmetric / 4500 V classification supported by the majority of sources and ABB’s 5SHY asymmetric series context; (2) a small number of pages misstate the package as TO-247AB, whereas datasheet metadata explicitly specifies a DISK BUTTON / ceramic-metal sealed press-pack housing, consistent with IGCT construction. A minority listing also categorizes the device as a gate-drive unit or a low-current processor module, which does not align with the power-semiconductor ratings reported elsewhere. For design, replacement, or procurement-critical use, the definitive electrical, thermal, and mechanical ratings should be verified against the official ABB / Hitachi Energy datasheet for the exact order code.
