SJ6016NRP

Overview

The Littelfuse SJ6016NRP is a Silicon Controlled Rectifier (SCR) designed for high-temperature phase control applications. It features a rated repetitive off-state voltage of 600 V and an RMS on-state current of 16 A. The device operates within a junction temperature range of -40°C to +150°C, utilizing a TO-220AB package for through-hole mounting. Key electrical characteristics include a maximum holding current of 25 mA, a gate trigger voltage of 1.5 V, and a gate trigger current of 6 mA. The component exhibits a forward voltage drop of 1.6 V at rated current and maintains a low off-state leakage current of 10 µA.

Feature Summary

• High thermal stability with a maximum operating junction temperature of 150°C
• Sensitive gate triggering requiring minimal drive current for reliable switching
• Robust construction suitable for demanding industrial power control environments

Applications

• Industrial motor speed controls
• Resistive heating systems
• Capacitive discharge circuits for ignition systems

Procurement Notes

Verify the specific suffix against official Littelfuse documentation to confirm exact thermal and electrical tolerances. Ensure the procurement channel provides valid traceability and authenticity certificates. Confirm that the TO-220AB package dimensions match the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when applications require a 16 A SCR capable of sustained operation at elevated temperatures up to 150°C. The 600 V rating suits standard AC line voltage applications. Consider the 6 mA gate trigger requirement for driver circuit compatibility. Verify that the through-hole mounting style aligns with the assembly process constraints.

Part Context

This part belongs to the Littelfuse SJ series of high-temperature SCRs. These devices are engineered for robust performance in power electronics where standard temperature ratings are insufficient. The series supports various current ratings while maintaining consistent gate sensitivity and thermal resilience across the product family.

Replacement Considerations

Direct replacements must match the 16 A current, 600 V voltage, and TO-220AB package. Verify equivalent thermal ratings and gate trigger specifications. Cross-reference with other manufacturers' high-temperature SCR lines ensuring identical pinout and mechanical dimensions.
