Scrs Procurement Notes
Verify the specific datasheet version when sourcing, as manufacturing site transfers have occurred. Confirm compliance with RoHS3 specifications and ensure the package marking aligns with the TOP3 or TO-220AB variant requirements for your assembly process. Cross-reference the DigiKey part number 497-TYN840RG-ND for accurate distributor identification.
Scrs Selection Notes
Select this component for applications requiring high current handling in a through-hole configuration. The 800 V rating provides sufficient margin for standard AC line voltages. Consider the 35 mA gate trigger requirement when designing the drive circuitry to ensure reliable turn-on without excessive driver power dissipation.
Scrs Part Context
This SCR belongs to STMicroelectronics' family of high-current thyristors designed for robust industrial environments. The TYN series specifically emphasizes durability through its clip assembly construction, distinguishing it from wire-bonded alternatives. It serves as a fundamental discrete power switch for managing significant loads in AC systems.
Scrs Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and thermal resistance characteristics if considering alternative manufacturers for direct replacement.
