SRR6012D1TP

Overview

The Littelfuse SRR6012D1TP is a standard Silicon Controlled Rectifier (SCR) from the Teccor SRR60 series, designed for phase control and general switching applications. It features a DPAK-2 (TO-252-2) surface-mount package with glass-passivated junctions. Key electrical parameters include a maximum repetitive peak reverse voltage of 600 V and an average on-state current rating of 12 A. The device supports a non-repetitive surge current of up to 120 A and has a maximum gate trigger current of 6 mA at approximately 1.5 V. It operates within a junction temperature range of -40°C to 150°C.

Feature Summary

• Standard phase control SCR optimized for reliable unidirectional switching in power circuits.
• Sensitive gate design allows triggering with low microampere currents from sense coils or microprocessors.
• Glass-passivated junctions provide enhanced durability and protection against environmental stress.

Applications

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

Procurement Notes

Verify the specific suffix 'TP' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official Littelfuse documentation prior to integration. Ensure the DPAK-2 footprint matches the target PCB layout. Validate thermal management requirements for the TO-252-2 package under expected load conditions.

Selection Notes

Select this component for applications requiring a 12 A RMS current rating and 600 V blocking capability in a compact surface-mount form factor. Compare gate trigger sensitivity against driving circuit capabilities. Consider the 120 A surge rating for transient protection needs. Evaluate thermal dissipation constraints inherent to the DPAK-2 package for high-duty-cycle operations.

Part Context

This part belongs to the Littelfuse Teccor SRR60xx series of 12 Amp Standard SCRs. The series offers voltage capabilities up to 600 V and surge ratings up to 120 A. The SRR6012D1TP specifically denotes the standard gate version in the DPAK-2 package, distinct from sensitive gate variants like the SVxx12x1 series.

Replacement Considerations

Direct replacements must match the 12 A current, 600 V voltage, and TO-252-2 package. Verify gate trigger characteristics (Igt/Vgt) to ensure compatibility with existing drive circuits. Cross-reference with other manufacturers' standard SCRs in the same series family for equivalent performance metrics.
