SJ6016N2TP

Overview

The Littelfuse SJ6016N2TP is a high junction temperature silicon-controlled rectifier (SCR) rated for 600 V blocking voltage and 16 A RMS on-state current. It utilizes a TO-263 (D2-Pak) surface-mount package with a sensitivity of 10 mA gate trigger current. The device supports an operating junction temperature range from -40°C to 150°C, enabling reliable performance in demanding thermal environments. Key electrical characteristics include a peak non-repetitive surge current capability of 225 A at 60 Hz and a critical rate of rise of on-state current (di/dt) of 125 A/µs.

Feature Summary

• High junction temperature rating up to 150°C for robust operation
• Surface-mount D2-Pak package design for automated assembly
• Low gate trigger current sensitivity for efficient microprocessor interfacing
• Internally constructed isolated package structure

Applications

• Capacitive discharge systems for strobe lights
• Gas engine ignition circuits
• Inrush current controllers
• Phase control in heating applications
• Motor speed controls

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm the exact package type and packing configuration. Confirm that the component meets RoHS compliance and halogen-free requirements if mandated by your project specifications. Ensure proper handling procedures are followed during storage and installation to maintain device integrity.

Selection Notes

Select this component when a surface-mount SCR is required for high-temperature environments. The 10 mA gate sensitivity allows for direct interfacing with standard logic levels. Designers should ensure adequate heat sinking to manage power dissipation and limit continuous current to 75% of the rated value to extend operational life under worst-case conditions.

Part Context

This part belongs to the SJxx16xx series of 16 Amp high junction temperature SCRs manufactured by Littelfuse. The series provides uni-directional switching solutions designed for phase control and inrush limiting. The 'N' designation indicates the TO-263 surface-mount package variant within this product family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit parameters before considering alternative components from other manufacturers.

FAQ

What is the maximum allowable case temperature for the SJ6016N2TP?

The maximum operating junction temperature is 150°C. The maximum allowable case temperature varies based on the RMS on-state current and must be determined using the derating curves provided in the datasheet.

How does the gate trigger current vary with temperature?

The DC gate trigger current decreases as the junction temperature increases. Normalized graphs in the datasheet show the ratio of IGT at various temperatures relative to the value at 25°C.

Is the mounting tab electrically isolated?

Yes, the N-package (TO-263) offers an internally constructed isolated package structure, providing high isolation voltage between the mounting tab and the internal circuitry.
