SRR6016D1TP

Overview

The Littelfuse SRR6016D1TP is a standard silicon-controlled rectifier (SCR) in the SRR6016xx series, designed for phase control and general switching applications. It features a TO-252AA (D-Package) surface-mount package with glass-passivated junctions. The device supports an RMS on-state current of 16 A at a case temperature of 100°C and offers voltage blocking capabilities up to 600 V. Triggering requires minimal gate current, with a maximum IGT of 6 mA and a maximum VGT of 1.5 V. Peak non-repetitive surge current reaches 160 A at 60 Hz. Operating junction temperatures range from -40°C to 125°C, with storage temperatures spanning -40°C to 150°C.

Feature Summary

• Sensitive gate design allows direct interfacing with microprocessors using low trigger currents.
• Glass-passivated junctions provide durability and reliability under harsh conditions.
• RoHS compliant construction ensures compatibility with lead-free reflow soldering processes.

Applications

• Capacitive discharge ignition systems for motorcycle engines and portable generators
• Strobe lights and pneumatic nailers
• Generic rectifiers, battery voltage regulators, and converters
• Controls for power tools and home appliances

Procurement Notes

Verify the specific ordering suffix against official Littelfuse documentation before procurement. The 'TP' suffix indicates tube packaging, while 'RP' denotes reel packaging; these affect handling but not electrical function. Confirm that the component meets RoHS standards and matches the required thermal management specifications for the target application environment.

Selection Notes

Select this SCR based on its 16 A RMS current rating and 600 V blocking voltage. Ensure the application's peak surge currents remain within the 160 A limit at 60 Hz. Design considerations should include limiting continuous current to 75% of the rated value and implementing adequate heat sinking to manage junction temperatures between -40°C and 125°C.

Part Context

This component belongs to the Littelfuse T eccor brand SRR6016xx Series of 16 Amp Standard SCRs. The series provides unidirectional switching solutions optimized for precise control in low-current circuits. The D1 designation specifically identifies the 600 V voltage rating variant within this family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify pinout compatibility and electrical ratings if considering alternative manufacturers for the TO-252AA package.
