K2000E70RP3

Overview

The Littelfuse K2000E70RP3 is a standard bidirectional SIDAC from the Kxxxzy series, functioning as a silicon voltage-triggered switch. It features a breakover voltage range of 190V to 215V and a repetitive peak off-state voltage of 180V. The device supports an on-state RMS current of 1A at 50/60Hz and handles a peak non-repetitive surge current of 20A at 60Hz. Packaged in a TO-92 form factor with RP3 reel packaging, it operates within a junction temperature range of -40°C to 125°C and includes glass-passivated junctions for environmental ruggedness.

Feature Summary

• Bidirectional switching capability via negative resistance region
• Glass-passivated junctions for harsh environment durability
• RoHS compliant construction

Applications

• High voltage power supplies
• Natural gas igniters
• High-pressure Sodium lamps
• Xenon flash ignition systems

Procurement Notes

Verify the specific ordering suffix RP3 confirms the TO-92 package type and reel pack quantity of 2000 units. Ensure the base part number K2000 matches the required 190V to 215V breakover voltage range. Confirm RoHS compliance status if required by the assembly process. Check datasheet revision dates for any parameter updates prior to final design integration.

Selection Notes

Select this component when a bidirectional trigger is needed for AC circuits requiring a breakover voltage between 190V and 215V. The TO-92 package suits through-hole mounting applications. Consider the 1A RMS current rating for load requirements. Evaluate thermal resistance parameters for heat dissipation needs in enclosed designs.

Part Context

This device belongs to the Kxxxzy Series of Standard Bidirectional SIDACs manufactured by Littelfuse. The series offers various breakover voltages and package options including DO-15, DO-214, and TO-92. The K2000 variant specifically targets applications requiring approximately 200V triggering thresholds.

Replacement Considerations

Cross-reference other K2000 variants such as K2000G or K2000S for different package types. Verify that substitute parts maintain the same 190V to 215V breakover voltage range and 1A RMS current rating to ensure circuit compatibility.
