SJ6012NRP

Overview

The Littelfuse SJ6012NRP is a Silicon-Controlled Rectifier (SCR) designed for high-temperature applications. It features a 600 V repetitive peak off-state voltage and an RMS on-state current rating of 12 A. The device operates within a junction temperature range of -40°C to 150°C. Key electrical parameters include a maximum non-repetitive surge current of 100 A at 50 Hz and 120 A at 60 Hz, a holding current maximum of 15 mA, and a gate trigger voltage maximum of 1.5 V. The component utilizes a TO-220R package for through-hole mounting.

Feature Summary

• High junction temperature capability up to 150°C for robust thermal performance
• Sensitive gate design allowing direct interfacing with microprocessors
• Glass-passivated junctions for enhanced durability and reliability

Applications

• Phase control in heating systems
• Motor speed controls
• Capacitive discharge ignitions

Procurement Notes

Verify the exact suffix against official Littelfuse documentation to confirm pinout and packaging variations. Ensure the selected variant matches the required thermal management specifications for the target application environment.

Selection Notes

Select this component for uni-directional switching applications requiring high surge tolerance. Confirm that the 12 A RMS rating and 600 V blocking voltage align with the circuit's operational limits and transient requirements.

Part Context

This SCR belongs to the Littelfuse SJ series, which focuses on high-temperature silicon-controlled rectifiers. The series is engineered for demanding electronic controls where standard components may fail due to thermal stress or harsh operating conditions.

Replacement Considerations

Consult Littelfuse datasheets for cross-reference options. Verify compatibility of gate trigger characteristics and package dimensions before substituting with other manufacturers' SCRs.
