SV6020L2QTP

Overview

The Littelfuse SV6020L2QTP is a Silicon Controlled Rectifier (SCR) belonging to the SVxx20xx series. It features a TO-220L package with three leads for through-hole mounting. The device supports a repetitive peak reverse voltage of 600 V and an average on-state current of 20 A. It withstands a surge current of 300 A. Key gate parameters include a maximum gate trigger current of 6 mA and a maximum gate trigger voltage of 1.5 V. The holding current is rated at 22 mA. The component operates within a temperature range from -40°C to 150°C.

Feature Summary

• High thermal stability with a maximum junction temperature rating of 150°C
• Robust surge handling capability rated at 300 A
• Low gate drive requirement with a maximum trigger current of 6 mA

Applications

• Industrial motor control systems
• Power supply circuits requiring high current switching
• General purpose rectification in industrial equipment

Procurement Notes

Verify the specific suffix 'L2' against official Littelfuse documentation to confirm pinout configuration and thermal characteristics, as suffixes often denote distinct mechanical or electrical variants within the same series. Ensure the procurement channel provides traceable datasheets matching the exact part number to avoid receiving functionally different equivalents.

Selection Notes

Select this component when a 600 V blocking voltage and 20 A continuous current capacity are required in a TO-220L form factor. Confirm that the application's thermal management can sustain the 150°C junction limit under expected load conditions. Verify that the gate drive circuitry can reliably supply the specified 6 mA trigger current without exceeding the 1.5 V threshold.

Part Context

This SCR is part of the SVxx20xx family, which shares common electrical ratings such as the 20 A current and 600 V voltage specifications. The SV6020L2QTP variant specifically utilizes the TO-220L package style. Other members in this series may differ in packaging type or specific thermal resistance values while maintaining identical core electrical performance metrics.

Replacement Considerations

Cross-reference with SV6020L1TP for alternative packaging options within the same electrical specification set. Verify compatibility with SV6020L1QTP if tube packaging is preferred over the standard bulk format. Always validate pinout alignment before substitution.
