S2006DS3RP

Overview

The Littelfuse S2006DS3RP is a sensitive silicon-controlled rectifier (SCR) designed for half-wave unidirectional gate-controlled rectification. It features a non-isolated TO-251 (V-Pak) surface-mount package with a maximum on-state current of 6 A and a repetitive peak off-state voltage rating of 600 V. The device utilizes glass-passivated junctions to ensure parameter stability and long-term reliability. Key electrical characteristics include a DC gate trigger current of 500 µA, a peak one-cycle forward surge current of 100 A, and an operating temperature range from -40 °C to +110 °C.

Feature Summary

• Glass-passivated junction construction provides a rugged barrier against contamination and ensures long-term parameter stability.
• Surface-mount TO-251 (V-Pak) package design facilitates automated assembly and space-efficient PCB integration.
• High surge capability supports demanding transient conditions with robust peak forward current ratings.

Applications

• Half-wave rectification in low-power AC/DC conversion circuits
• Gate control applications requiring high sensitivity triggering
• General-purpose switching in consumer electronics and industrial control systems

Procurement Notes

Verify the specific suffix DS3RP corresponds to the non-isolated TO-251 package variant with 600 V blocking voltage and 500 µA gate sensitivity. Confirm RoHS compliance status and check for any End-of-Life notices or recommended replacement part numbers prior to finalizing procurement orders.

Selection Notes

Select this component when a surface-mount SCR with 600 V blocking capability and 6 A continuous current handling is required. Ensure the application circuit can provide at least 500 µA of gate trigger current. Verify that the thermal management strategy accommodates the specified junction temperature limits under expected load conditions.
