SRR6012R1TP

Overview

The Littelfuse SRR6012R1TP is a standard Silicon Controlled Rectifier (SCR) belonging to the Teccor SRR60 series. It features a 600 V repetitive peak reverse voltage and supports an average on-state current of 12 A with a surge capability of 120 A. The device utilizes a TO-252 (DPAK-2) surface-mount package for efficient PCB integration. Designed as a sensitive gate SCR, it requires minimal gate trigger current, typically in the microampere range, allowing direct interfacing with low-power control logic such as microprocessors or proximity switches.

Feature Summary

• Sensitive gate architecture enables reliable triggering with microampere-level currents from sense coils or microprocessors.
• Glass-passivated junctions provide robust protection against environmental stress and ensure long-term stability.
• Surface-mount DPAK-2 packaging facilitates automated assembly and compact circuit board design.

Applications

• Phase control circuits for AC power regulation
• General switching applications in heating systems
• Motor control interfaces
• Capacitive discharge ignition systems

Procurement Notes

Verify the specific suffix 'R1' against the manufacturer's official documentation to confirm reel quantity and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the datasheet revision date to validate electrical parameters before finalizing procurement orders.

Selection Notes

Select this component when a surface-mount SCR with 12 A continuous current handling is required. The sensitive gate characteristic makes it suitable for applications driven by low-current digital outputs. Verify that the TO-252 thermal dissipation capabilities align with the expected duty cycle and ambient temperature conditions of the design.

Part Context

This part belongs to the Teccor SRR60xx series of 12 Amp Standard SCRs. The series offers voltage ratings up to 600 V and surge capabilities up to 120 A. These devices are engineered as excellent unidirectional switches for phase control and general switching applications requiring high reliability and compact form factors.

Replacement Considerations

Direct replacements within the same family include SRR6012D1RP and SRR6012D1TP. Verify pinout compatibility and thermal resistance values when substituting components from different manufacturers or series.
