SJ6016L1TP

Overview

The Littelfuse SJ6016L1TP is a high junction temperature Silicon Controlled Rectifier (SCR) rated for 600 V repetitive peak reverse voltage and 16 A RMS on-state current. It utilizes a TO-220L isolated package with a maximum junction temperature of 150°C. The device features a low gate trigger current of 6 mA maximum at 1.5 V, enabling efficient control in phase firing circuits. Peak non-repetitive surge current reaches 225 A at 60 Hz, while the critical rate of rise of on-state current is specified at 125 A/µs.

Feature Summary

• Electrically isolated mounting tab design for simplified heat sinking
• High thermal tolerance supporting operation up to 150°C junction temperature
• Low gate sensitivity requiring minimal drive power for triggering

Applications

• Phase control in heating systems
• Motor speed controls
• Converters and rectifiers
• Inrush current controllers
• Capacitive discharge systems for strobe lights and gas engine ignition

Procurement Notes

Verify component authenticity by checking the manufacturer's official datasheet specifications against the physical marking code. Confirm that the part number suffix matches the required voltage rating and gate sensitivity. Ensure the package type aligns with the intended isolation requirements before finalizing procurement orders.

Selection Notes

Select this component when an electrically isolated SCR is required for high-temperature environments. The 6 mA gate sensitivity suits applications needing low-power driver interfaces. Verify that the 600 V blocking voltage meets the circuit's peak line-to-line or transient voltage requirements. Ensure adequate heatsinking is provided to maintain the junction temperature within the 150°C limit during continuous operation.

Part Context

This device belongs to the SJxx16xx series of high junction temperature SCRs manufactured by Littelfuse. The series offers various voltage ratings and package options, including isolated and non-isolated configurations. The specific model denotes a 600 V rating with 6 mA gate sensitivity housed in a TO-220L package.

Replacement Considerations

Direct replacements must match the 600 V rating, 16 A current capacity, and TO-220L isolated package. Verify that substitute parts offer equivalent or superior gate trigger currents and thermal resistance characteristics to ensure reliable circuit performance.
