Overview
The Littelfuse SJ6040L2TP is a high-temperature silicon-controlled rectifier (SCR) from the SJxx40xx series, designed for uni-directional switching applications. It features a 400 V repetitive off-state voltage and a 40 A RMS on-state current rating at a case temperature of 55°C. The device utilizes a low gate trigger current of 15 mA with a maximum gate trigger voltage of 1.5 V. It operates within a junction temperature range of -40°C to 150°C and offers a peak non-repetitive surge current capability of up to 520 A at 60 Hz. The component is housed in an isolated TO-220AB package.
Feature Summary
- Capable of operating at high junction temperatures up to 150°C to manage thermal stress in limited cooling environments
- Offers low gate sensitivity requiring only 15 mA to trigger, facilitating efficient control circuit design
- Features an internally constructed isolated mounting tab for enhanced isolation voltage and simplified heat sinking
Applications
- AC rectifiers and voltage regulators
- Phase control in heating systems
- Motor speed controls
- AC solid-state switches
- Commercial appliances and white goods
Procurement Notes
Verify the specific ordering suffix against the manufacturer's datasheet to confirm the exact voltage rating, gate sensitivity, and package type. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the assembly process.
Selection Notes
Select this component when applications require high thermal stability and reliable switching under moderate load conditions. Ensure the thermal management system maintains the case temperature within limits specified for the desired RMS current rating. Verify that the dv/dt ratings are sufficient for the specific line noise environment.
Part Context
This part belongs to the SJxx40xx series of 40 Amp standard high-temperature SCRs. The '60' indicates a 600V rating in the general series nomenclature, but the 'L2' suffix specifies the 400V variant with 15mA gate sensitivity. The 'TP' suffix denotes tube packaging.
Replacement Considerations
Consult the official Littelfuse product selector table for direct equivalents within the SJxx40xx family. Consider parts with matching voltage and current ratings if different gate sensitivities or packages are required.
