The SANREX PD70F160 is a high-voltage thyristor/diode module rated at 70A continuous current and 1600V repetitive peak voltage. This combination module integrates a thyristor and freewheeling diode in a single isolated package, reducing board space and simplifying thermal management in power conversion designs. As a discontinued component, the PD70F160 is no longer manufactured, making reliable aftermarket sourcing essential for facilities dependent on legacy equipment. The robust construction and proven SANREX packaging make this module a trusted solution in high-reliability industrial environments.

The PD70F160 is widely used in industrial AC motor drives, soft starters, resistance welding controllers, and phase-controlled rectifier assemblies. Its 1600V voltage class provides adequate margin in 690V AC line applications, and the integrated diode simplifies inductive load commutation in half-controlled bridge topologies. Maintenance engineers servicing legacy CNC equipment, crane drives, injection molding machines, and steel mill auxiliary drives frequently encounter this module as a direct replacement. The single-module format also benefits retrofit designs where replacing discrete thyristor and diode components with a consolidated package improves system reliability.

Key Features of the PD70F160:

• 70A average on-state current (IT(AV)) suitable for medium-power industrial converter stages
• 1600V repetitive peak off-state voltage (VDRM/VRRM) providing margin on 690V AC bus systems
• Integrated freewheeling diode eliminates external discrete component in half-controlled bridge configurations
• Isolated base plate construction simplifies heatsink mounting and meets standard power module footprint requirements
• Low thermal resistance junction-to-case supports high-cycle industrial duty applications with proper heatsink selection
• SANREX-standard screw terminal connections compatible with legacy PCB and busbar wiring layouts

With the PD70F160 carrying an official factory lead time of 99 weeks and classified as obsolete by SANREX, procurement teams cannot rely on standard distribution channels to meet urgent maintenance or production timelines. Unplanned downtime caused by a failed thyristor/diode module in a production drive or rectifier system can cost far more than the component itself. Sourcing from a distributor with verified physical inventory—not broker allocations or unconfirmed stock—is the only dependable path to getting equipment back online quickly. ATI Accurate Technology maintains genuine new OEM inventory of obsolete SANREX modules specifically to support these critical situations.
