S2006DS2RP

Scrs Overview

The Littelfuse S2006DS2RP is a half-wave unidirectional, gate-controlled rectifier (SCR) from the Teccor line of sensitive SCRs. It features a non-isolated TO-252 (D-Pak) package and offers a rated repetitive peak off-state voltage (VDRM/VRRM) of 200 V. The device has an RMS on-state current rating of 6 A at a case temperature of 25 °C, with a maximum DC gate trigger current (IGT) of 200 µA. Key electrical parameters include a peak on-state voltage (VTM) of 1.6 V, a holding current (IH) of 0.8 mA, and a peak one-cycle forward surge current (ITSM) of 100 A. The operating junction temperature range extends from -40 °C to +110 °C.

Scrs Feature Summary

• Glass-passivated junctions for long-term reliability and parameter stability
• Sensitive gate design enabling easy triggering by sense coils, proximity switches, and microprocessors
• High surge capability supporting demanding switching applications

Scrs Applications

• Phase control circuits
• Heating control systems
• Motor speed controls
• Capacitive discharge ignitions

Scrs Procurement Notes

Verify the specific part number against official Littelfuse documentation to confirm package type and sensitivity class. Ensure that the selected component meets the required voltage and current ratings for the intended application. Check for RoHS compliance status as indicated in the manufacturer's datasheet. Confirm availability through authorized distributors or direct manufacturer channels.

Scrs Selection Notes

Select this SCR based on its 200 V blocking voltage and 6 A RMS current capacity. Consider the 200 µA gate trigger requirement for compatibility with low-power control signals. Evaluate thermal management needs using the provided derating curves for the TO-252 package. Ensure the application does not require electrical isolation between the case and leads, as this variant is non-isolated.

Scrs Part Context

This component belongs to the Sxx06xSx series of sensitive SCRs, which are designed for uni-directional switch applications. The series includes variants with different voltage ratings and gate sensitivities. The TO-252 package provides surface mount convenience while maintaining robust power handling capabilities suitable for industrial and consumer electronics.

Scrs Replacement Considerations

Compatible substitutes within the same family include S4006DS2RP (400 V rating) and S6006DS2RP (600 V rating). Other series members like S2006VS2 offer isolated packages if higher isolation voltage is required. Verify pinout compatibility and thermal characteristics when substituting.
