Overview
The Littelfuse SJ6025R1ATP is a high-temperature silicon-controlled rectifier (SCR) from the SJxx25xxA series, rated for 25 A RMS on-state current and 600 V repetitive peak off-state voltage. It features a sensitive gate with a maximum trigger current of 6 mA at approximately 1.5 V. The device supports a junction temperature range of -40°C to 150°C and withstands surge currents up to 350 A at 60 Hz. Packaged in a non-isolated TO-220AB (R-package), it is AEC-Q101 qualified for automotive applications.
Feature Summary
- High junction temperature capability up to 150°C
- Sensitive gate design allowing direct microprocessor interfacing
- AEC-Q101 qualification for automotive reliability
- Halogen-free and RoHS-compliant construction
Applications
- AC generator rectifiers
- Battery voltage regulators
- Inrush current controllers
- Soft starters for low power AC motors
Procurement Notes
Verify the specific ordering suffix against the manufacturer's official datasheet to confirm package type and sensitivity level. Ensure the component meets the required AEC-Q101 automotive standards if used in vehicle systems. Cross-reference the part number with Littelfuse documentation to validate availability and compliance status before procurement.
Selection Notes
Select this component for uni-directional switching applications requiring high thermal stability. The 6 mA gate sensitivity facilitates control via low-power logic circuits. Ensure the circuit design limits continuous current to 75% of the rating and provides adequate heat sinking to maintain junction temperatures within the specified operating range.
Part Context
This SCR belongs to the SJxx25xxA family, designed for robust performance in demanding environments. The 'R' designation indicates a non-isolated TO-220AB package, while '1' specifies the 6 mA gate sensitivity. The 'A' suffix denotes AEC-Q101 qualification, distinguishing it from standard industrial variants.
Replacement Considerations
Compatible replacements include other parts within the SJxx25xxA series with matching voltage and current ratings. Verify that substitute components share the same TO-220R package and 6 mA gate sensitivity to ensure electrical compatibility without redesigning the drive circuitry.
FAQ
What is the maximum gate trigger current for the SJ6025R1ATP?
The maximum DC gate trigger current (IGT) is 6 mA.
Is the mounting tab electrically isolated?
No, the R-package variant has a non-isolated mounting tab common with the center lead.
What is the peak non-repetitive surge current rating?
The device can withstand a peak non-repetitive surge current of 350 A at 60 Hz for a single half cycle.
