S8055R67

Scrs Overview

The Littelfuse S8055R67 is a Teccor brand SCR rated for 800V repetitive peak off-state voltage and 55A RMS on-state current. It utilizes a TO-220 Non-Isolated Tab package with a maximum junction temperature of 150°C. The device features a non-repetitive surge current capability of 100A, a gate trigger voltage of 1.5V, and a holding current of 60mA. It operates within a temperature range of -40°C to +150°C.

Scrs Feature Summary

• Electrically isolated package design
• High thermal stability up to 150°C junction temperature
• Standard phase control triggering characteristics

Scrs Applications

• Phase control applications
• Heating controls
• Motor speed controls

Scrs Procurement Notes

Verify the specific suffix 'R67' against the official Littelfuse datasheet to confirm it denotes the TO-220 Non-Isolated Tab package variant. Ensure the required 150°C thermal rating aligns with system constraints. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement specifications.

Scrs Selection Notes

Select this component for applications requiring high thermal endurance and standard phase control functionality. The 150°C rating offers superior performance compared to standard 125°C devices. Verify that the 800V blocking voltage and 55A RMS current meet the circuit's electrical demands without exceeding the 100A surge limit.

Scrs Part Context

This part belongs to the Teccor Sxx55x series of 55 Amp Standard SCRs manufactured by Littelfuse. The series provides robust thyristor solutions for power electronics. The S8055R67 specifically represents the 800V voltage class within this lineup, designed for reliable operation in demanding industrial environments.

Scrs Replacement Considerations

Consult the Littelfuse Sxx55x series cross-reference guide for verified substitutes. Ensure any replacement maintains the 800V VDRM, 55A IT(RMS), and TO-220 Non-Isolated Tab form factor.
