SJ6016R1TP

Scrs Overview

The Littelfuse SJ6016R1TP is a high junction temperature Silicon-Controlled Rectifier (SCR) rated for 600V and 16A RMS on-state current. It utilizes a TO-220R non-isolated package with a maximum operating junction temperature of 150°C. The device features a sensitive gate trigger requiring a maximum IGT of 6 mA at approximately 1.5 V. Electrical characteristics include a peak non-repetitive surge current of 225 A at 60 Hz, a critical rate of rise of on-state current (di/dt) of 125 A/µs, and a maximum on-state voltage of 1.6 V. Thermal resistance from junction to case is specified at 1.0 °C/W.

Scrs Feature Summary

• Capable of operation at elevated junction temperatures up to 150°C
• Sensitive gate design allows direct interfacing with low-power control circuits
• High surge current capability supports demanding switching loads
• Non-isolated mounting tab facilitates efficient heat sinking

Scrs Applications

• Phase control in heating systems
• Motor speed controls
• Converters and rectifiers
• Inrush current controllers
• Capacitive discharge ignition systems

Scrs Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm the exact package type and gate sensitivity parameters. Ensure that thermal management designs account for the 1.0 °C/W junction-to-case resistance rating under continuous load conditions. Confirm compliance with RoHS and REACH directives prior to integration into final assemblies.

Scrs Selection Notes

Select this component when applications require high thermal stability and robust surge handling capabilities. The 6 mA gate sensitivity makes it suitable for microprocessor-driven control interfaces without additional amplification. Evaluate the non-isolated tab configuration to ensure proper electrical isolation strategies are implemented within the system chassis or heatsink assembly.

Scrs Part Context

This part belongs to the SJxx16xx series of 16 Amp high junction temperature SCRs manufactured by Littelfuse. The series offers various voltage ratings and package options, including isolated and non-isolated configurations. The R-package designation specifically indicates a standard TO-220 form factor with a common anode mounting tab.

Scrs Replacement Considerations

Consult the official Littelfuse product selector for equivalent parts within the SJxx16xx family. Verify that any substitute maintains the 600V blocking voltage, 16A RMS current rating, and compatible TO-220 footprint dimensions.
