SJ6012R1TP

Overview

The SJ6012R1TP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse, designed for high-temperature applications. It features a 600V repetitive peak off-state voltage and supports an RMS on-state current of 12A with an average on-state current of 7.6A. The device operates within a junction temperature range of -40°C to 150°C. Key electrical parameters include a maximum gate trigger voltage of 1.5V and a maximum gate trigger current of 6mA. It has a maximum on-state voltage of 1.6V and a non-repetitive surge current rating of 100A at 50Hz or 120A at 60Hz. The component utilizes a TO-220AB through-hole package.

Feature Summary

• High junction temperature capability up to 150°C for robust thermal performance
• Low gate trigger current requirement of 6mA maximum for sensitive drive circuits
• Standard recovery type construction suitable for general phase control

Applications

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

Procurement Notes

Verify the specific suffix R1 against official Littelfuse documentation to confirm pinout configuration and exact mechanical dimensions. Ensure the procurement channel provides valid RoHS compliance certificates. Cross-reference the manufacturer part number with authorized distributor databases to confirm authenticity and traceability before finalizing orders.

Selection Notes

Select this component when uni-directional switching is required in high-temperature environments. The 12A RMS rating suits moderate power loads. Verify that the 600V blocking voltage exceeds the circuit's peak reverse voltage. Confirm that the driving circuit can supply the necessary 6mA gate current for reliable triggering under all operating conditions.

Part Context

This SCR belongs to the SVxx12xx series from Littelfuse, which focuses on high junction temperature thyristors. The series is engineered for reliability in demanding industrial applications. The TO-220AB package facilitates efficient heat dissipation through direct mounting to heatsinks, supporting the device's high thermal specifications.

Replacement Considerations

Direct replacements must match the 12A RMS current, 600V voltage, and TO-220AB package. Verify equivalent gate trigger characteristics and thermal resistance values. Consult Littelfuse technical support for validated cross-reference data to ensure functional compatibility.
