S6006DTP

Overview

The Littelfuse S6006DTP is a silicon-controlled rectifier (SCR) designed for surface-mount applications. It features a rated repetitive off-state voltage of 600 V and an RMS on-state current of 6 A. The device utilizes a sensitive gate architecture, requiring a maximum gate trigger current of 200 µA at a maximum voltage of 800 mV. It operates within a junction temperature range of -40°C to 110°C and is housed in a TO-252-3 (DPAK) package. Key electrical parameters include a maximum on-state voltage of 1.6 V, a holding current of 6 mA, and a non-repetitive surge current capability of up to 100 A.

Feature Summary

• Sensitive gate design enables direct interfacing with microprocessors and low-power control circuits.
• Glass-passivated junctions provide enhanced durability against environmental stressors.
• Surface-mount DPAK packaging facilitates automated assembly and compact board layouts.

Applications

• Capacitive discharge ignition systems for power tools and gas engines.
• Phase control and heating regulation in consumer appliances.
• Motor speed control circuits for industrial and household equipment.

Procurement Notes

Verify the specific suffix 'DTP' against official Littelfuse documentation to confirm tape-and-reel packaging and exact lot traceability. Ensure the component meets RoHS3 compliance requirements for the target market. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and avoid counterfeit components during sourcing.

Selection Notes

Select this component when a 600 V blocking voltage and 6 A continuous current are required in a surface-mount form factor. The sensitive gate characteristic makes it suitable for applications driven by low-current logic outputs or sense coils. Consider thermal management constraints associated with the TO-252 package for high-duty-cycle operations.

Part Context

This SCR belongs to the Littelfuse Sxx06x series, which offers various voltage ratings and package options for 6 A applications. The S6006DTP specifically addresses the need for robust switching in space-constrained designs where traditional through-hole packages are impractical. It complements other variants like the TO-220 or TO-202 versions for different thermal and mechanical requirements.

Replacement Considerations

Compatible substitutes include the S6006DS2RP and S6006VS2TP from Littelfuse, which share similar electrical characteristics. Verify pinout compatibility and thermal resistance differences before substituting to ensure circuit performance remains within specifications.
