SRJ6018DRP

Scrs Overview

The SRJ6018DRP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse Inc. It features an 18 A RMS on-state current and an 800 V maximum repetitive peak off-state voltage. The device operates within a junction temperature range of -40°C to +125°C. It utilizes a DPAK-2 (TO-252-2) surface-mount package for efficient thermal management. Key electrical characteristics include a gate trigger voltage of 1.5 V and a holding current of 30 mA. The component supports non-repetitive surge currents up to 100 A, ensuring robust performance in high-power switching applications.

Scrs Procurement Notes

Verify the specific Littelfuse datasheet revision to confirm exact electrical tolerances and thermal resistance values before finalizing designs. Ensure that the procurement source provides original manufacturer documentation to validate RoHS compliance status. Cross-reference the part number against official Littelfuse databases to avoid counterfeit components. Confirm that the supplier offers traceability records consistent with industry standards for critical power electronics.

Scrs Selection Notes

Select this component when designing circuits requiring high current density in a compact surface-mount footprint. Evaluate the thermal dissipation requirements based on the TO-252-2 package limitations. Consider the gate trigger characteristics for compatibility with available drive circuitry. Assess the voltage ratings against peak line voltages to ensure adequate safety margins during operation.

Scrs Part Context

This SCR belongs to the broader family of thyristor devices used for power control. It complements other surface-mount SCRs from Littelfuse offering similar current or voltage ratings. The series provides options for various packaging styles to suit different manufacturing constraints. Engineers often choose this type for replacing through-hole equivalents in space-constrained modern electronic assemblies.

Scrs Replacement Considerations

Consult official Littelfuse substitution guides for verified equivalent part numbers. Direct replacements must match the 18 A current and 800 V voltage ratings. Verify pinout compatibility for the TO-252-2 package. Do not assume interchangeability without confirming electrical parameter alignment.
