Overview
The Littelfuse SJ6020NATP 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-263AB (D2-Pak) surface-mount package with a non-isolated mounting tab. The device features a sensitive gate trigger level of 6 mA maximum at approximately 1.5 V. It supports an operating junction temperature range of -40°C to +150°C and offers peak non-repetitive surge current capabilities of up to 300 A at 60 Hz. The component is AEC-Q101 qualified and RoHS compliant.
Feature Summary
- High junction temperature capability up to 150°C for demanding thermal environments
- Sensitive gate design allowing direct interfacing with microprocessors via low trigger current
- Automotive-grade qualification ensuring reliability under rigorous environmental stress tests
Applications
- AC generator rectifiers
- Battery voltage regulators
- Generic converters and inrush current controllers
- Power tool controls
- Home appliance electronics
Procurement Notes
Verify the specific ordering suffix against the manufacturer's datasheet to confirm the exact gate sensitivity and packaging configuration. Ensure that the procurement documentation explicitly states AEC-Q101 qualification if automotive compliance is required. Confirm the package type matches the intended PCB footprint before finalizing orders.
Selection Notes
Select this component when applications require high thermal stability and surface-mount convenience. The 6 mA gate sensitivity allows for efficient drive circuits. Designers must account for the non-isolated tab during heat sinking implementation. Verify that the circuit's dv/dt requirements are met by the device's specified rating to prevent false triggering.
Part Context
This part belongs to the SJxx20xxA family of 20 Amp high junction temperature SCRs manufactured by Littelfuse. The 'N' designation indicates the TO-263 surface-mount package, while '60' specifies the 600V blocking voltage rating. The '1' suffix denotes the 6mA gate sensitivity variant within this product line.
Replacement Considerations
Compatible alternatives within the same series include SJ6020RATP (TO-220 non-isolated) and SJ6020LATP (TO-220 isolated). Cross-package replacements require careful evaluation of thermal resistance differences and mechanical mounting constraints.
