SJ6020N2ARP

Scrs Overview

The Littelfuse SJ6020N2ARP is a high-temperature Silicon-Controlled Rectifier (SCR) from the SJxx20xxA series, rated for 20 A RMS on-state current and available in 400 V or 600 V blocking voltage configurations. It utilizes a TO-263AB (D2-Pak) surface-mount package with an embossed carrier reel packing mode. The device features a maximum junction temperature of 150 °C and supports peak non-repetitive surge currents up to 300 A at 60 Hz. Gate trigger characteristics include a maximum gate trigger voltage of 1.5 V and sensitivity options of 6 mA, 10 mA, or 35 mA; this specific model corresponds to the 10 mA sensitivity variant.

Scrs Feature Summary

Scrs Procurement Notes

Verify the exact ordering suffix against the manufacturer's official datasheet to confirm the specific gate sensitivity level and voltage rating required for your circuit design. Ensure that the procurement channel sources components directly from authorized distributors to guarantee authenticity and traceability. Confirm compliance with RoHS and REACH standards as specified in the product documentation before finalizing orders.

Scrs Selection Notes

Select this component based on the required RMS current handling and peak blocking voltage for the target application. Consider the thermal resistance and case temperature limits when designing the heat sinking solution. Verify that the gate drive circuitry can supply the necessary trigger current and voltage levels to ensure reliable turn-on under all operating conditions.

Scrs Part Context

This part belongs to the SJxx20xxA family of 20 Amp high junction temperature SCRs manufactured by Littelfuse. The series offers various voltage ratings and package types, including isolated and non-isolated through-hole options alongside surface-mount variants. The 'N' designation indicates the TO-263AB surface-mount package, while the '2' suffix specifies the 10 mA gate sensitivity characteristic.

Scrs Replacement Considerations

Direct replacements within the same series include SJ6020N1A (6 mA sensitivity) and SJ6020N3A (35 mA sensitivity). Cross-package equivalents such as SJ6020R2A (TO-220R) may be considered if layout changes are permissible. Verify pinout compatibility and thermal performance metrics before substituting.
