S8012DRP

Scrs Overview

The Littelfuse S8012DRP is a silicon-controlled rectifier (SCR) rated for 12 A RMS on-state current and an 800 V repetitive peak off-state voltage. It features a maximum non-repetitive surge current of 120 A and a holding current of up to 40 mA. The device operates within a temperature range of -40 °C to +125 °C and utilizes a TO-252-3 surface-mount package. Key electrical characteristics include a forward voltage of 1.6 V, a gate trigger voltage of 1.5 V, and a gate trigger current of 20 mA.

Scrs Feature Summary

• Sensitive gate structure allows direct interfacing with microprocessors using minimal gate current.
• Glass passivated junction design ensures durability against environmental stressors.
• Compatible with lead-free reflow soldering processes for modern manufacturing requirements.

Scrs Applications

• Capacitive-discharge ignition systems
• Fluid level sensors
• Strobe light control circuits

Scrs Procurement Notes

Verify the specific suffix DRP indicates reel packaging when ordering. Confirm RoHS compliance status through official Littelfuse documentation prior to integration. Ensure the procurement channel provides valid traceability for the component batch. Cross-reference the manufacturer part number with distributor listings to confirm availability and authenticity before finalizing purchase orders.

Scrs Selection Notes

Select this component for applications requiring high-voltage blocking capability in a compact surface-mount form factor. The 800 V rating suits medium-voltage switching tasks where smaller packages are preferred over axial leads. Verify that the 12 A RMS current capacity meets the load requirements and that the sensitive gate drive specifications align with the control circuit capabilities.

Scrs Part Context

This SCR belongs to the Sxx12x series from Littelfuse, designed for efficient switching in low-current circuits. The series offers various voltage ratings while maintaining consistent current handling and package dimensions. This specific model provides an 800 V option within the family, bridging the gap between lower voltage SCRs and higher voltage modules.

Scrs Replacement Considerations

The S8012DTP serves as a tube-packaged alternative within the same electrical specification family. Both parts share identical electrical ratings and package footprint, differing primarily in shipping configuration. Verify pinout compatibility and thermal performance similarities before substituting one for the other in existing designs.
