The Sanrex PD70FG160 is a hybrid thyristor/diode power module engineered for demanding industrial switching and rectification environments. Combining thyristor and diode elements within a single ruggedized package, this module simplifies circuit design while delivering reliable performance in high-current, high-voltage DC bus applications. Its compact topology is well-suited for integration into drive cabinets and power conversion assemblies where board space and thermal management are critical design constraints. As an obsolete component, the PD70FG160 represents Sanrex's legacy of precision power semiconductor engineering trusted across global industrial installations.

The PD70FG160 sees continued demand in legacy AC/DC motor drives, variable frequency drive front-end rectifier stages, UPS systems, welding power supplies, and industrial heating controllers. Maintenance engineers servicing older capital equipment—where replacing entire drive assemblies is cost-prohibitive—rely on exact module replacements to restore uptime quickly. The module's combined thyristor/diode construction makes it a direct fit for half-controlled and fully controlled bridge configurations commonly found in installed base machinery throughout manufacturing, oil and gas, marine, and utility industries.

Quick Reference: PD70FG160

Key Features of the PD70FG160:

• Integrated thyristor and diode elements in a single isolated base module, reducing component count and simplifying thermal interface design
• 70A average on-state current rating suitable for medium-power industrial drive and rectifier stages
• 1600V repetitive peak off-state voltage (VDRM/VRRM) providing robust margin in 690VAC line-connected applications
• Isolated copper baseplate construction for direct heatsink mounting, enabling predictable junction-to-case thermal resistance management
• Gate trigger characteristics optimized for compatibility with standard thyristor firing circuits and phase-angle control boards
• Designed to Sanrex's high-reliability manufacturing standards, consistent with modules deployed in continuous-duty industrial power systems

The PD70FG160 has been discontinued by Sanrex, and new factory production carries a 99-week lead time—making open-market procurement the only practical path for unplanned maintenance or emergency repair scenarios. Engineers managing aging drives and power conversion equipment cannot afford extended downtime waiting on factory orders. Sourcing from a stocking distributor with verified new OEM inventory is the fastest and most reliable solution. ATI Accurate Technology specializes in exactly this scenario: obsolete and long-lead-time power semiconductors held in stock and ready for immediate deployment.

ATI Accurate Technology is located in Palmetto, Florida and ships same-day on orders received before 5PM EST. We stock IGBTs, thyristors, diodes, and rectifier modules including hard-to-find and obsolete parts like the PD70FG160. Volume pricing is available for MRO stocking orders and OEM procurement.
