Overview
The Littelfuse SJ6040NATP is a Silicon Controlled Rectifier (SCR) from the SJxx40xx series, rated for 600 V repetitive off-state voltage and 40 A RMS on-state current. It utilizes a TO-263AB (D2PAK) surface-mount package with an isolated tab. Key electrical parameters include a maximum gate trigger current of 15 mA, a maximum gate trigger voltage of 1.5 V, and a maximum on-state voltage of 1.7 V. The device supports non-repetitive surge currents of 430 A at 50 Hz and 520 A at 60 Hz. It operates within a junction temperature range of -40°C to 150°C and features standard recovery characteristics.
Feature Summary
- Surface-mount construction in a thermally efficient D2PAK package with electrically isolated mounting tab
- High thermal stability supporting operation up to 150°C junction temperature
- Robust surge handling capability for industrial power control environments
Applications
- Industrial motor speed controls
- Solid-state relays
- Power regulation circuits
Procurement Notes
Verify the specific suffix 'NATP' against the official Littelfuse datasheet to confirm pinout orientation and isolation specifications. Ensure the ordering quantity aligns with manufacturer tube packaging standards. Confirm RoHS compliance status matches current regulatory requirements before finalizing procurement orders.
Selection Notes
Select this component when a surface-mount SCR with high current capacity is required. Compare the 40 A RMS rating against load requirements. Verify that the TO-263AB footprint fits the PCB layout. Consider the 600 V blocking voltage relative to peak line voltages in the target application circuit design.
Part Context
This part belongs to the SJxx40xx family of thyristors designed for general-purpose power switching. It shares core electrical ratings with through-hole variants like the SJ6040R2TP but offers surface-mount convenience. The series is engineered for reliability in industrial power conversion and control applications requiring robust semiconductor switching.
Replacement Considerations
The SJ6040R2TP serves as a direct functional equivalent with identical electrical ratings but uses a TO-220AB through-hole package. Substitution requires PCB redesign to accommodate the different physical footprint and mounting method.
