Overview
The Littelfuse SJ6020R1ATP is a high-temperature Silicon-Controlled Rectifier (SCR) from the SJxx20xxA series, rated for 600 V repetitive off-state voltage and 20 A RMS on-state current. It utilizes a TO-220AB non-isolated package with a maximum junction temperature of 150 °C. The device features a sensitive gate trigger requiring a maximum IGT of 6 mA at approximately 1.5 V. Electrical characteristics include a peak non-repetitive surge current of 300 A at 60 Hz, a maximum holding current of 15 mA, and an on-state voltage drop of 1.6 V at 40 A. It is AEC-Q101 qualified and RoHS compliant.
Feature Summary
- High thermal capability supporting operation up to 150°C junction temperature
- Sensitive gate design enabling direct interfacing with microprocessors
- Robust surge handling with 300 A peak non-repetitive current rating
- Automotive-grade qualification ensuring reliability in demanding environments
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 the manufacturer's datasheet to confirm the exact package type and packing mode. The 'TP' suffix indicates tube packaging, while other suffixes may denote reel configurations. Confirm that the component meets the required AEC-Q101 automotive standards if intended for vehicle applications. Ensure the gate sensitivity matches the driver circuit capabilities before finalizing procurement.
Selection Notes
Select this component when designing circuits requiring high junction temperature tolerance and sensitive gate triggering. The 6 mA gate current requirement allows for efficient drive from low-power logic. Consider the thermal resistance of 1.0 °C/W for heat sinking calculations. Verify that the application voltage does not exceed the 600 V rating under worst-case transient conditions to prevent device failure.
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 packages including TO-220L, TO-220R, and TO-263. The SJ6020R1ATP specifically combines the 600 V blocking capability with the 6 mA sensitive gate option in a standard non-isolated TO-220R configuration.
Replacement Considerations
Compatible substitutes within the same family include SJ6020R2ATP (10 mA gate sensitivity) and SJ6020R3ATP (35 mA gate sensitivity). For isolated mounting requirements, consider the SJ6020L1ATP variant which uses the TO-220L package. Surface mount alternatives are available in the D2-Pak format, such as the SJ6020N1ATP.
