SCRs - Modules Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct pinout and electrical tolerances. Confirm that the D-55 mounting interface matches the heatsink specifications in the target design. Check for recent Product Change Notifications regarding manufacturing site updates or material composition changes before finalizing procurement orders.

SCRs - Modules Selection Notes

Select this component when a single-phase SCR with high current handling is required for phase-controlled applications. Ensure the system voltage does not exceed the 1000 V rating and that the thermal design can dissipate heat effectively given the 70 A continuous current rating. Consider the gate drive requirements, specifically the 2.5 V and 120 mA limits, when designing the triggering circuitry.

SCRs - Modules Part Context

This part belongs to the TzzRIA series of single-phase SCR modules from Vishay. These modules are engineered for high-power industrial applications requiring reliable phase control. The D-55 package provides a standardized mechanical footprint for easy integration into existing power electronics architectures.

SCRs - Modules Replacement Considerations

Consult the official Vishay cross-reference documentation for verified substitutes. Potential alternatives may include other D-55 packaged SCRs from Vishay or competitors, provided they match the 1000 V voltage rating and 70 A current capacity.
