S6012RTP

Overview

The Littelfuse S6012RTP is a Silicon Controlled Rectifier (SCR) from the Teccor SVxx12xx series, designed for phase control and general switching applications. It features a TO-220L through-hole package with three pins. Key electrical parameters include a repetitive peak reverse voltage of 600 V and an average on-state RMS current rating of 12 A. The device supports a non-repetitive surge current of 120 A. Gate triggering characteristics specify a maximum gate trigger current of 6 mA and a maximum gate trigger voltage of 1.5 V. The component operates within a temperature range of -40°C to +150°C and complies with RoHS standards.

Feature Summary

• Sensitive gate design enabling reliable triggering with low microampere currents from sense coils or microprocessors.
• Glass-passivated junctions providing robust protection against voltage transients and environmental stress.
• High surge current capability suitable for demanding power control and motor drive circuits.

Applications

• Phase control in AC power regulation systems
• General switching applications including heating controls
• Motor control circuits and converters/rectifiers
• Capacitive discharge ignition systems

Procurement Notes

Verify the specific suffix 'RTP' against official Littelfuse documentation to confirm tape-and-reel packaging versus tube configuration. Ensure the selected variant matches the required lead frame finish and compliance certifications for the target assembly process. Cross-reference the manufacturer part number with authorized distributors to confirm current production status and availability.

Selection Notes

Select this component when a 12 A RMS current rating and 600 V blocking voltage are required in a TO-220L package. The 6 mA gate trigger current makes it suitable for standard logic-level driving without excessive gate drive power. Consider thermal management requirements for the TO-220L case, as heat dissipation depends on the mounting surface area and ambient conditions during continuous operation.

Part Context

This SCR belongs to the Littelfuse Teccor SVxx12xx family, which offers standard and sensitive gate options in various packages. The S6012RTP specifically utilizes the TO-220L form factor, distinguishing it from surface-mount variants like the S6012DRP in DPAK packages. This family is engineered for cost-effective power control solutions requiring reliable switching performance.

Replacement Considerations

Direct replacements must match the 12 A / 600 V / TO-220L specification. Equivalent parts from other manufacturers should be verified for identical pinout compatibility and thermal resistance characteristics. Ensure substitute devices meet the same RoHS compliance and glass-passivation requirements for environmental durability.
