Overview
The Littelfuse SJ6020N1ARP is a high junction temperature silicon-controlled rectifier (SCR) from the SJxx20xxA series, rated for 600 V repetitive peak off-state voltage and 20 A RMS on-state current. It utilizes a TO-263AB (D2-Pak) surface-mount package with an operating junction temperature range of -40°C to +150°C. The device features a sensitive gate trigger level of 6 mA maximum at approximately 1.5 V. Electrical characteristics include a maximum forward voltage of 1.6 V at 40 A, a non-repetitive surge current capability of 300 A at 60 Hz, and a critical rate of rise of on-state current (di/dt) of 125 A/µs. It is qualified under AEC-Q101 standards.
Feature Summary
- High thermal performance supporting operation up to 150°C junction temperature
- Sensitive gate design enabling direct interfacing with microprocessors
- Robust surge handling capabilities for demanding switching applications
- Automotive-grade qualification ensuring reliability in harsh environments
Applications
- AC generator rectifiers and battery voltage regulators
- Phase control circuits for heating elements and motor speed controls
- Inrush current controllers in AC to DC converters
- Controls for power tools and home appliances
Procurement Notes
Verify the specific ordering suffix 'RP' corresponds to the embossed carrier reel packaging configuration rather than standard tube packing. Confirm that the component meets RoHS compliance and halogen-free requirements as specified by the manufacturer. Ensure the selected part number aligns with the required 6 mA gate sensitivity and 600 V blocking voltage ratings for the intended circuit design.
Selection Notes
Select this component when a surface-mount SCR with high thermal tolerance is required for uni-directional switching. The TO-263AB package facilitates efficient heat sinking through the mounting tab. Designers should account for the 6 mA maximum gate trigger current to ensure reliable firing from low-power control signals while maintaining compatibility with automotive-level manufacturing controls.
Part Context
This device 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 packages, including isolated and non-isolated options. The SJ6020N1ARP specifically combines the 600 V rating with the sensitive gate characteristic in a D2-Pak surface-mount form factor.
Replacement Considerations
Compatible alternatives within the same family include SJ6020N1TP, which shares identical electrical specifications but utilizes tube packaging instead of the embossed carrier reel format.
