Overview
The Littelfuse SJ6025RATP is a high-temperature Silicon-Controlled Rectifier (SCR) from the SJxx25xxA series, rated for 25 A RMS on-state current and available in 400 V or 600 V blocking voltage configurations. It utilizes a TO-220R non-isolated 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 surge currents up to 350 A at 60 Hz half-cycle and includes AEC-Q101 automotive qualification.
Feature Summary
- High thermal capability with a maximum junction temperature of 150°C
- Sensitive gate trigger levels allowing direct interfacing with microprocessors
- Automotive Level manufacturing control with AEC-Q101 qualification
- Halogen-free and RoHS-compliant construction
Applications
- AC Generator (ACG) rectifiers
- Battery voltage regulators
- Inrush current controllers in AC to DC applications
- Soft starters for low power AC motors
- Controls for power tools and home appliances
Procurement Notes
Verify the specific voltage rating (400V or 600V) and gate sensitivity code (1 for 6mA, 2 for 10mA, or blank/3 for 35mA) required for the application. Confirm the TO-220R non-isolated package type matches the heat sinking design. Ensure compliance with AEC-Q101 standards if used in automotive contexts.
Selection Notes
Select based on the required blocking voltage and gate drive current availability. The TO-220R package requires careful mounting torque management (max 8 in-lbs). Design should limit continuous current to 75% of the component rating to ensure longevity against overheating and surge events.
Part Context
This component belongs to the SJxx25xxA series of 25 Amp high junction temperature SCRs manufactured by Littelfuse. The 'R' suffix indicates the TO-220R non-isolated mounting tab configuration, while 'A' denotes the automotive qualification level. It is designed for uni-directional switching in demanding environments.
Replacement Considerations
Compatible substitutes within the same family include SJ6025LxATP (isolated TO-220L package) and SJ6025NxATP (surface mount TO-263 package), provided the isolation requirements and PCB layout accommodate the physical differences.
