Overview
The Littelfuse SJ6020N2ATP is a high-temperature Silicon-Controlled Rectifier (SCR) from the SJxx20xxA series, rated for 20 A RMS on-state current and 600 V blocking voltage. It utilizes a TO-263 (D2-Pak) surface-mount package with a maximum junction temperature of 150°C. The device features a sensitive gate trigger level of 10 mA maximum at approximately 1.5 V. Electrical characteristics include a peak non-repetitive surge current of 300 A at 60 Hz and a thermal resistance from junction to case of 1.0 °C/W. It is AEC-Q101 qualified and RoHS compliant.
Feature Summary
- High junction temperature capability up to 150°C for demanding environments
- Sensitive gate triggering allows direct interfacing with microprocessors
- Automotive-grade qualification ensures reliability in vehicle applications
- Surface-mount D2-Pak package facilitates automated assembly
Applications

Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm the exact package type, sensitivity rating, and packing configuration. Ensure that the procurement documentation explicitly states compliance with the required environmental standards and automotive quality certifications before finalizing orders.
Selection Notes
Select this component based on the required RMS current handling and voltage blocking capabilities relative to the circuit design. Consider the thermal management requirements associated with the TO-263 package and the specified junction-to-case thermal resistance. Verify that the gate drive circuitry can supply the necessary trigger current and voltage levels for reliable switching under all operating temperatures.
Part Context
This part belongs to the SJxx20xxA series of 20 Amp high junction temperature SCRs manufactured by Littelfuse. The series offers various voltage ratings and gate sensitivities across different package options, including through-hole and surface-mount configurations. The 'N' designation indicates the TO-263 surface-mount package, while '2' specifies the 10 mA gate sensitivity variant.
Replacement Considerations
Consult the official Littelfuse datasheet for confirmed substitute part numbers within the same family or alternative manufacturers offering equivalent electrical specifications and package dimensions.
