Overview
The Littelfuse SJ4016N2TP is a Silicon Controlled Rectifier (SCR) designed for high-temperature applications. It features a rated repetitive peak off-state voltage of 400 V and an on-state RMS current of 16 A. The device operates within a junction temperature range of -40°C to +150°C. Key electrical parameters include a forward voltage of 1.6 V, a gate trigger voltage of 1.5 V, and a gate trigger current of 35 mA. The non-repetitive on-state current is 225 A, with a maximum holding current of 35 mA. It utilizes a TO-263 (D2PAK) surface mount package.
Feature Summary
- Engineered for high junction temperature operation up to 150°C
- Surface mount construction in a TO-263 package for automated assembly
- Standard recovery characteristics suitable for general switching applications
Applications
- Industrial motor control systems
- High-temperature power supply circuits
- General purpose AC/DC switching applications
Procurement Notes
Verify the specific suffix 'N2' against the manufacturer's latest datasheet to confirm pinout and thermal specifications. Ensure the selected component meets the required RoHS compliance standards for the target market. Cross-reference the package outline dimensions with the PCB footprint design to guarantee mechanical compatibility during assembly.
Selection Notes
Select this component when a surface mount SCR is required for high-temperature environments exceeding standard ratings. Compare the 16 A RMS current capability against the circuit's continuous load requirements. Evaluate the 400 V blocking voltage against peak line voltages to ensure adequate safety margins for the intended application.
Part Context
This part belongs to the SJ series of SCRs from Littelfuse, which are characterized by their ability to operate at elevated temperatures. The series offers various current ratings and packages, with the SJ4016N2TP providing a 16 A solution in a D2PAK form factor. It serves as a robust alternative to through-hole devices in space-constrained designs.
Replacement Considerations
Consult official Littelfuse documentation for direct cross-reference data. Verify that any substitute maintains the same TO-263 package and 400V/16A ratings. Confirm thermal performance matches the original specification.
