The PGH100N16 is a high-voltage thyristor module manufactured by Nihon, rated for 100A continuous current and 1600V repetitive peak off-state voltage. Thyristor modules in this class are engineered for reliable phase control and switching in high-power industrial circuits, offering robust thermal performance through a compact, industry-standard module package. The PGH100N16 is built to withstand the demanding electrical stresses found in heavy industrial environments, making it a dependable solution for engineers specifying or replacing SCR-based power control assemblies.

The PGH100N16 sees widespread use across industrial motor drives, AC power regulators, soft starters, resistance heating controllers, and DC power supplies where controlled rectification at high voltage and current is required. It is also commonly found in crane and hoist drive systems, electrochemical processing equipment, UPS systems, and traction power converters. Maintenance engineers replacing failed thyristor modules in legacy equipment frequently encounter this Nihon part, and its 1600V voltage class makes it suitable for demanding 690V AC line applications with adequate safety margin.

Quick Reference: PGH100N16

Key Features of the PGH100N16:

• 1600V repetitive peak off-state voltage (VDRM/VRRM) providing ample margin for 690V AC bus applications
• 100A average on-state current (IT(AV)) suitable for high-power phase control and rectifier circuits
• Isolated baseplate construction for simplified heatsink mounting and electrical isolation in multi-module assemblies
• Low on-state voltage drop minimizing conduction losses and reducing thermal load on the heatsink
• Gate trigger characteristics compatible with standard SCR firing boards and phase control ICs
• Compact module footprint enabling direct replacement in existing drive and rectifier assemblies without mechanical modification

With a current factory lead time of 99 weeks for new production of the PGH100N16, procurement teams and MRO buyers cannot afford to wait on a manufacturer queue when equipment goes down or scheduled maintenance demands a replacement. Nihon thyristor modules of this voltage and current class have increasingly long production cycles, and the risk of extended downtime is real for facilities that rely on this part. Sourcing from a distributor with confirmed in-stock inventory eliminates that exposure entirely and protects both production schedules and maintenance windows.
