SV6020R1TP

Overview

The Littelfuse SV6020R1TP is a Silicon-Controlled Rectifier (SCR) from the SVxx20xx series, designed for high-temperature uni-directional switching applications. It features a TO-220R non-isolated package with a maximum repetitive peak reverse voltage of 600 V and an RMS on-state current rating of 20 A at a case temperature of 130 °C. The device supports a peak non-repetitive surge current of 300 A at 60 Hz and operates within a junction temperature range of -40 °C to 150 °C. Gate triggering characteristics include a maximum gate trigger current of 6 mA and a maximum gate trigger voltage of 1.5 V.

Feature Summary

• High junction temperature capability up to 150 °C for robust thermal performance
• Sensitive gate design allowing direct interfacing with microprocessors via low trigger current
• High dv/dt performance to minimize false triggering risks in demanding environments
• RoHS compliant and halogen-free construction

Applications

• AC generator rectifiers and battery voltage regulators
• Phase control in heating systems and motor speed controls
• Inrush current controllers for AC to DC converters
• Controls for power tools and home appliances

Procurement Notes

Verify the specific ordering suffix against official Littelfuse documentation to confirm the exact package type and sensitivity level. Confirm RoHS compliance status and agency approvals such as UL recognition before finalizing procurement specifications. Ensure that the selected component meets the required isolation or non-isolation requirements for the intended circuit design.

Selection Notes

Select this component based on its 600 V blocking voltage and 20 A RMS current capacity suitable for phase control applications. Consider the TO-220R non-isolated mounting tab configuration for heat sinking requirements. Evaluate the 6 mA gate sensitivity for compatibility with available drive circuits and ensure the operating environment stays within the specified -40 °C to 150 °C junction temperature limits.

Part Context

This part belongs to the SVxx20xx series of 20 Amp High Junction Temperature SCRs manufactured by Littelfuse. The series includes variants with different voltage ratings, gate sensitivities, and package types such as TO-220L, TO-220R, and TO-263. These devices are engineered for reliable performance in high-temperature industrial and consumer electronic applications requiring efficient switching capabilities.

Replacement Considerations

Direct replacements within the same series include SV6020L1TP (TO-220L isolated) and SV6020N1TP (TO-263 surface mount). Verify pinout compatibility and thermal resistance differences when substituting between package types. Ensure the alternative part maintains the same 600 V rating and 6 mA gate sensitivity for equivalent electrical performance.
