Overview
The Littelfuse SJ6020RATP is a high-temperature Silicon Controlled Rectifier (SCR) from the SJxx20xxA series, rated for 20 A RMS on-state current at a case temperature of 130 °C. It features a peak non-repetitive blocking voltage of 600 V and supports an average on-state current of 12.8 A under the same thermal conditions. The device operates within a junction temperature range of -40 °C to 150 °C and withstands a peak surge current of 300 A at 60 Hz. It utilizes a TO-220AB non-isolated package with a junction-to-case thermal resistance of 1.0 °C/W.
Feature Summary
- AEC-Q101 qualified for automotive Level manufacture control
- Halogen-free and RoHS compliant construction
- High junction temperature capability up to 150 °C
- Surge current capability up to 300 A at 60 Hz half cycle
Applications
- AC Generator (ACG) rectifiers
- Battery voltage regulators
- Generic converters in AC to DC applications
- Inrush current controllers
- Controls for power tools and home appliances
Procurement Notes
Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and gate sensitivity. The 'TP' suffix indicates tube packing with a base quantity of 500 units. Ensure the selected voltage rating matches the circuit requirements, as the '60' designation corresponds to 600 V blocking capability. Confirm compliance with RoHS and halogen-free standards if required by the assembly process.
Selection Notes
Select this component for uni-directional switching applications requiring high thermal stability. The non-isolated TO-220R package requires careful mounting to ensure proper heat sinking while maintaining electrical isolation from the heatsink if necessary. Consider the 6 mA maximum gate trigger current for low-power drive circuits. Evaluate the di/dt rating of 125 A/μs to prevent turn-on failures during rapid current transitions.
Part Context
This part belongs to the SJxx20xxA series of 20 Amp high junction temperature SCRs manufactured by Littelfuse Inc. The series includes variants with different voltage ratings (400 V or 600 V) and gate sensitivities (6 mA, 10 mA, or 35 mA). The SJ6020RATP specifically denotes the 600 V version in the non-isolated TO-220R package with tube packaging.
Replacement Considerations
Direct substitutes within the same family include SJ6020L1A, SJ6020N1A, SJ6020R2A, and SJ6020N2A, depending on the required package and gate sensitivity. Verify that any replacement maintains the 600 V blocking voltage and 20 A current rating.
