Overview
The Littelfuse SJ6012NTP is a high junction temperature Silicon Controlled Rectifier (SCR) from the SJxx12xx series, housed in a TO-263 (D²Pak) surface-mount package. It features a maximum repetitive peak reverse voltage of 600 V and an RMS on-state current rating of 12 A at a case temperature of 135°C. The device has a peak non-repetitive surge current capability of 120 A at 60 Hz and a maximum gate trigger current of 6 mA. Operating within a junction temperature range of -40°C to 150°C, it includes UL 1557 recognition as an electrically isolated semiconductor device.
Feature Summary
- High thermal performance with a maximum junction temperature of 150°C
- Electrically isolated construction for simplified heat sinking
- Sensitive gate design requiring low trigger current
- Halogen-free and RoHS compliant manufacturing
Applications
- Capacitive discharge systems for strobe lights and gas engine ignition
- Phase control in heating elements and motor speed controls
- Inrush current limiting circuits
- Power tools and home appliance AC to DC converters
Procurement Notes
Verify the specific ordering suffix against the manufacturer's datasheet to confirm the exact package type, voltage rating, and gate sensitivity. Confirm that the component meets the required isolation standards for your application. Check for updated revision notices or agency approvals before finalizing procurement specifications.
Selection Notes
Select this component based on the required blocking voltage and RMS current ratings relative to the expected case temperature. Ensure the circuit design accounts for the critical rate of rise of on-state current and provides adequate dv/dt protection. Verify that the surface-mount footprint matches the TO-263 dimensions provided in the mechanical drawings.
Part Context
This part belongs to the SJxx12xx series of 12 Amp high junction temperature SCRs manufactured by Littelfuse. The series offers various packages including TO-220L, TO-220R, TO-263, TO-251, and TO-252. The 'N' designation specifically identifies the TO-263 D²Pak surface-mount variant within this family.
Replacement Considerations
Consult the official Littelfuse selector guide for direct equivalents within the SV or SRR series that match the 600V, 12A, and TO-263 requirements. Verify pinout compatibility and thermal resistance values when substituting with other manufacturers' devices.
