Overview
The Littelfuse SJ6040NRP is a 40 Amp standard high temperature Silicon Controlled Rectifier (SCR) from the SJxx40xx series. It features a 600 V repetitive peak off-state voltage and a sensitive gate trigger current of 15 mA at approximately 1.5 V. The device is housed in a TO-263 (D²Pak) surface-mount package with an RMS on-state current rating of 40 A and an average on-state current of 25 A. It supports a peak non-repetitive surge current of up to 520 A at 60 Hz and operates within a junction temperature range of -40°C to 150°C.
Feature Summary
- High junction temperature capability for demanding thermal environments
- Sensitive gate trigger levels requiring low control power
- Robust surge current handling for transient protection
- Surface-mount D²Pak package design for automated assembly
Applications
- AC rectifier circuits
- Voltage regulator systems
- Industrial power tools
- Exercise equipment
- White goods and commercial appliances
Procurement Notes
Verify the specific voltage rating suffix, as the SJ6040NRP designation indicates a 600V variant within the broader SJxx40Nx family. Confirm that the embossed carrier packing mode aligns with your manufacturing line's pick-and-place requirements. Ensure the component meets RoHS compliance standards required by your target market regulations before finalizing procurement orders.
Selection Notes
Select this component when a surface-mount SCR with high thermal endurance is required. The 15 mA gate sensitivity allows for direct interfacing with low-power logic controllers. Verify that the PCB layout accommodates the TO-263 footprint and provides adequate copper area for heat dissipation to maintain the rated 40 A RMS current without exceeding thermal limits.
Part Context
This part belongs to the SJxx40xx series of 40 Amp high temperature SCRs manufactured by Littelfuse. The 'N' suffix denotes the TO-263 (D²Pak) surface-mount package, while the 'RP' suffix specifies the embossed carrier tape packaging. This series is engineered for uni-directional switching applications requiring reliable performance under high thermal stress conditions.
Replacement Considerations
Compatible replacements include other parts from the SJxx40Nx family, such as the SJ4040NRP for 400V applications or the SJ6040N2TP if a tube-packaged equivalent is needed. Ensure any substitute maintains the same TO-263 footprint and matches the 15 mA gate trigger sensitivity to preserve circuit control characteristics.
