SRR6012L1TP

Overview

The Littelfuse SRR6012L1TP is a standard Silicon Controlled Rectifier (SCR) from the Teccor SVxx12xx series, rated for 600 V repetitive peak reverse voltage and 12 A average on-state current. It utilizes a TO-252 (D²Pak) surface-mount package with glass-passivated junctions. The device features a sensitive gate requiring a maximum trigger current of 6 mA at approximately 1.5 V. It supports a non-repetitive surge current of up to 120 A and operates within a junction temperature range of -40°C to 150°C.

Feature Summary

• Sensitive gate design enables triggering with low microampere currents from sense coils or microprocessors.
• Glass-passivated junctions provide robust protection against voltage transients.
• High junction temperature rating ensures reliability in demanding thermal environments.

Applications

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

Procurement Notes

Verify the specific suffix 'L1TP' against official Littelfuse documentation to confirm the exact tape-and-reel packaging configuration and pinout orientation. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability. Cross-reference the RoHS compliance status with the latest manufacturer declarations prior to final ordering.

Selection Notes

Select this component when a surface-mount SCR with high thermal tolerance is required for phase control applications. The 6 mA gate sensitivity allows for direct interfacing with low-power logic circuits without additional driver stages. Consider the TO-252 package constraints for PCB layout and thermal dissipation requirements relative to the 12 A continuous current rating.

Part Context

This part belongs to the Littelfuse Teccor SVxx12xx series of 12 Amp SCRs. The series is engineered for uni-directional switching applications requiring high junction temperatures. Similar parts in the family include variants with different voltage ratings or package types, such as the through-hole SV6012L1TP or the D²Pak SV6012N1TP.

Replacement Considerations

Direct replacements must match the 600 V / 12 A / TO-252 specifications. Verify that substitute SCRs maintain compatible gate trigger characteristics and thermal performance. Consult Littelfuse datasheets for equivalent parts within the SVxx12xx series or comparable offerings from other manufacturers ensuring identical pinouts and electrical limits.
