Overview
The Littelfuse SJ6020NARP is a high-temperature Silicon-Controlled Rectifier (SCR) from the SJxx20xxA series, rated for 20 A RMS on-state current and available in 400 V or 600 V blocking voltage configurations. It utilizes a TO-263 (D2-Pak) surface-mount package with a maximum junction temperature of 150°C. The device features sensitive gate triggering options of 6 mA, 10 mA, or 35 mA maximum at approximately 1.5 V. It supports peak non-repetitive surge currents up to 300 A at 60 Hz and includes AEC-Q101 qualification for automotive reliability.
Feature Summary
- High thermal capability with a maximum junction temperature of 150°C
- Sensitive gate trigger levels enabling direct interfacing with microprocessors
- Robust surge handling with capabilities up to 300 A at 60 Hz half-cycle
- Automotive-grade reliability through AEC-Q101 qualification
Applications
- AC generator rectifiers
- Battery voltage regulators
- Inrush current controllers
- Power tool controls
- White goods appliance management
Procurement Notes
Verify the specific voltage rating (400V or 600V) and gate sensitivity suffix required for your design. Confirm the 'RP' designation indicates reel packaging rather than tube packing. Ensure the selected component meets the thermal dissipation requirements for your application's case temperature limits.
Selection Notes
Select based on the required blocking voltage and gate trigger current sensitivity. The N-package offers surface-mount convenience but requires careful thermal management due to its smaller footprint compared to through-hole alternatives. Verify that the circuit can handle the specified di/dt and dv/dt ratings to prevent false triggering or device failure.
Part Context
This component belongs to the SJxx20xxA family of 20 Amp high-temperature SCRs manufactured by Littelfuse. The series provides various voltage and sensitivity combinations across different packages, including isolated and non-isolated through-hole options alongside the surface-mount D2-Pak variant used here.
Replacement Considerations
Direct replacements within the same series include SJ6020N1A and SJ6020N2A, which share the TO-263 package but differ in gate sensitivity. Cross-package substitutes like SJ6020RATP offer similar electrical ratings but utilize a TO-220R through-hole configuration requiring different mounting considerations.
