Overview
The Littelfuse SJ6004DS2TP is a 4 Amp high-temperature sensitive silicon-controlled rectifier (SCR) in the SJxx04xSx series. It features a TO-252AA (D-PAK) surface-mount package and offers voltage ratings of 400V or 600V, with this specific model rated at 600V. The device has a maximum junction temperature of 150°C and a low gate trigger current of 200 μA maximum at approximately 0.8V. It supports an RMS on-state current of 4 A and peak non-repetitive surge currents up to 30 A at 60 Hz.
Feature Summary
- Sensitive gate design enabling reliable triggering with minimal control power
- High thermal stability supporting operation up to 150°C junction temperature
- Halogen-free and RoHS compliant construction for environmental safety
Applications
- Capacitive discharge ignition systems for motorcycle engines
- Portable generator engine ignition circuits
- Strobe lights and nailers
- Generic rectifiers and battery voltage regulators
- Power tool controls and home appliance converters
Procurement Notes
Verify the component marking matches the datasheet specification exactly. Confirm the package type corresponds to the required PCB layout. Ensure the voltage rating meets the circuit requirements. Check for compliance with relevant environmental standards if applicable.
Selection Notes
Select based on the required blocking voltage and current handling capabilities. Consider the thermal management needs given the 150°C junction limit. Evaluate the gate sensitivity requirements for the driving circuit. Ensure the package style fits the assembly process constraints.
Part Context
This part belongs to the SJxx04xSx series of 4 Amp high-temperature sensitive SCRs from Littelfuse. The series is designed for uni-directional switch applications requiring robust performance in demanding environments. The 'S2' suffix indicates the specific gate sensitivity level of 0.2 mA.
Replacement Considerations
Consult official Littelfuse documentation for verified substitute part numbers. Ensure any replacement maintains the same voltage, current, and package specifications.
