CS19-08HO1S-TUB

Scrs Overview

The CS19-08HO1S-TUB is a Silicon Controlled Rectifier (SCR) manufactured by IXYS, belonging to the CS19-08ho1S series. It features an 800 V rated repetitive off-state voltage and supports a maximum RMS on-state current of 31 A. The device has a non-repetitive peak surge current rating of 195 A and a forward voltage drop of 1.65 V. Gate triggering requires a maximum voltage of 1.5 V and current of 28 mA. It operates within a temperature range of -40°C to +125°C and is housed in a D2PAK-2 (TO-263-2) surface-mount package.

Scrs Feature Summary

• Surface-mount construction in a D2PAK-2 package for automated PCB assembly
• High thermal stability with a maximum operating junction temperature of 125°C
• Defined gate sensitivity with specified trigger voltage and current limits

Scrs Applications

• Industrial power control systems
• AC motor speed regulation circuits
• Solid-state relay implementations

Scrs Procurement Notes

Verify component authenticity through authorized IXYS distributors or certified suppliers. Confirm RoHS compliance status via official documentation before integration. Check for obsolescence notices as availability may be restricted. Ensure storage conditions meet semiconductor handling standards to prevent moisture damage prior to soldering.

Scrs Selection Notes

Select this SCR for applications requiring 800V blocking capability and up to 31A continuous current in a compact surface-mount form factor. Compare gate trigger requirements against driver circuit capabilities. Evaluate thermal management needs given the TO-263-2 package constraints. Consider alternative packages if higher current ratings or through-hole mounting are required.

Scrs Part Context

This component is part of the IXYS CS19 series of silicon controlled rectifiers designed for general-purpose power switching. The series offers various voltage and current ratings across different package types. The CS19-08 variant specifically targets medium-power applications needing reliable phase control and high-voltage isolation in a standardized SMD footprint.

Scrs Replacement Considerations

Consult IXYS datasheets for direct pin-compatible alternatives within the CS19 family. Verify electrical parameters match or exceed original specifications when sourcing substitutes from other manufacturers.
