The NIHON PGD100S16 is a 100A, 1600V thyristor module engineered for demanding power control applications where voltage blocking capability and reliable gate-triggered switching are essential. Built to industrial-grade standards, this module delivers stable forward current handling and high repetitive peak off-state voltage (VDRM) performance in a compact, thermally efficient package. Whether used in new equipment designs or as a direct replacement in legacy systems, the PGD100S16 provides the rugged, consistent performance that AC/DC converter and motor drive platforms require in continuous-duty environments.

The PGD100S16 is widely deployed in industrial AC/DC rectification systems, phase-controlled DC motor drives, soft starters, power regulators, and induction heating equipment. Its 1600V voltage class makes it well suited for medium-voltage input applications where transient overvoltages demand robust blocking margin. Utility-scale battery charging systems, crane and hoist drives, and resistance welding controllers are among the common end-use environments. Maintenance engineers replacing failed thyristor modules in installed equipment will find the PGD100S16 a direct fit where equivalent 100A/1600V SCR modules are specified.

Quick Reference: PGD100S16

Key Features of the PGD100S16:

• 1600V repetitive peak off-state voltage (VDRM/VRRM) for high-margin operation in medium-voltage circuits
• 100A average on-state current (IT(AV)) rated for continuous industrial duty cycles
• Low on-state voltage drop (VTM) minimizes conduction losses and reduces heatsink thermal load
• Isolated baseplate construction simplifies multi-module mounting on shared heatsinks without additional insulation hardware
• Gate trigger current and voltage characteristics compatible with standard SCR firing boards and pulse transformer drive circuits
• Compact module footprint enables drop-in replacement in existing drive cabinets and converter assemblies with minimal rework

NIHON thyristor modules are well established in industrial power electronics, but factory lead times for new production of the PGD100S16 currently run 99 weeks — nearly two years. For maintenance operations, that timeline is operationally unacceptable when a failed module is taking a drive or rectifier offline. Procurement teams building safety stock for critical equipment face the same challenge. ATI sources and inventories hard-to-find and long-lead-time devices like the PGD100S16 specifically to bridge this gap, providing new OEM stock when the factory pipeline cannot support urgent demand.

ATI Accurate Technology is a power semiconductor distributor located in Palmetto, Florida, stocking IGBTs, thyristors, diodes, and rectifier modules including obsolete and long-lead-time parts.
