Overview
The Littelfuse SJ6040R2TP is a standard high-temperature Silicon-Controlled Rectifier (SCR) from the SJxx40xx series. It features a TO-220AB non-isolated package with a rated repetitive off-state voltage of 600 V and an RMS on-state current of 40 A at a case temperature of 115°C. The device has a sensitive gate trigger requiring a maximum IGT of 15 mA at approximately 1.5 V. It supports peak non-repetitive surge currents of 430 A at 50 Hz and 520 A at 60 Hz. Operating junction temperatures range from -40°C to 150°C, with a maximum average on-state current of 25 A.
Feature Summary
- High thermal capability supporting operation up to 150°C junction temperature
- Sensitive gate design enabling direct interfacing with microprocessors
- Robust surge handling for demanding switching applications
Applications
- Phase control in heating systems
- Motor speed controls
- AC rectifiers and voltage regulators
- Industrial power tools
- Exercise equipment and commercial appliances
Procurement Notes
Verify the specific ordering suffix against the manufacturer's datasheet to confirm package isolation type and gate sensitivity. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the selected component matches the required voltage rating and thermal management specifications for the target application environment.
Selection Notes
Select this component for uni-directional switching applications requiring high temperature tolerance. Consider the 15 mA gate sensitivity for low-power drive circuits. Evaluate thermal resistance values and derating curves to ensure adequate heat sinking for continuous operation. Verify that the non-isolated mounting tab configuration fits the mechanical constraints of the design.
Part Context
This part belongs to the SJxx40xx series of 40 Amp Standard High Temperature SCRs manufactured by Littelfuse. The series includes variants with different voltage ratings (400V or 600V), gate sensitivities (15mA or 40mA), and packages (TO-220L, TO-220R, TO-263). The 'R' designation indicates a TO-220 non-isolated package, while '2' denotes 15mA gate sensitivity.
Replacement Considerations
Compatible substitutes within the same family include SJ6040L2TP (isolated package) and SJ6040RTP (40mA gate sensitivity). Verify pinout compatibility and thermal characteristics when substituting.
