• Power regulation circuits requiring high current capacity
• Motor speed control applications

SCRs - Modules Procurement Notes

Verify the specific D-55 T-Module pinout and mounting torque specifications against the official datasheet before integration. Confirm that the thermal interface material and heatsink design align with the required thermal resistance for the intended operating environment. Ensure gate drive circuitry provides sufficient current to meet the 120 mA maximum trigger requirement reliably under all load conditions.

SCRs - Modules Selection Notes

Select this component when a single-phase SCR solution with a 200 V rating and 90 A continuous current capability is required. The D-55 T-Module form factor is suitable for direct chassis mounting where space constraints allow for larger packages. Consider the 141 A RMS rating for thermal management calculations to ensure long-term operational reliability in high-power environments.

SCRs - Modules Part Context

This part belongs to the T90 series of SCR modules from Vishay, which are engineered for high-power industrial applications. The T-Module packaging technology offers superior thermal performance compared to traditional leaded devices, facilitating efficient heat dissipation directly to the mounting surface. This series is widely used in heavy-duty power electronics where reliability and current handling are critical.

SCRs - Modules Replacement Considerations

Direct replacements must match the 200 V voltage rating, 90 A/141 A current ratings, and D-55 T-Module mechanical footprint. Verify compatibility of gate trigger parameters and thermal characteristics. Cross-reference with other Vishay T90 variants or equivalent industry-standard modules ensuring identical mounting hole patterns and terminal configurations.
