K2200E70RP2

Overview

The Littelfuse K2200E70RP2 is a silicon bilateral voltage-triggered switch from the Kxxxzy SIDAC series, housed in a TO-92 package. It features a breakover voltage range of 205V to 230V and a repetitive peak off-state voltage of 180V. The device supports an on-state RMS current of 1A at 50/60Hz and can handle a peak non-repetitive surge current of up to 20A for a single cycle at 60Hz. Operating within a junction temperature range of -40°C to 125°C, it utilizes glass-passivated junctions for ruggedness.

Feature Summary

• Bilateral switching capability with negative resistance region conduction
• Glass-passivated junctions for environmental durability
• RoHS compliant construction

Applications

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

Procurement Notes

Verify the specific ordering suffix RP2 corresponds to the reel pack configuration containing 2000 units per base quantity. Confirm that the E70 designation matches the required TO-92 Type 70 lead form dimensions. Ensure compliance with RoHS standards is documented for the final assembly process. Cross-reference the manufacturer datasheet revision date against production lot codes to validate component authenticity and specification accuracy.

Selection Notes

Select this component when a bidirectional trigger switch with a 205V to 230V breakover threshold is required. The TO-92 package suits through-hole mounting applications where space allows. Verify that the circuit design accommodates the 1A RMS current rating and the dynamic holding current specifications. Consider the thermal resistance characteristics for proper heat dissipation in the target environment.

Part Context

This part belongs to the Kxxxzy Standard Bidirectional SIDAC family manufactured by Littelfuse. The series offers various breakover voltages and packaging options including DO-15, DO-214, and TO-92. The K2200 variant specifically targets mid-range voltage triggering needs within industrial and consumer electronics protection circuits.

Replacement Considerations

Compatible substitutes include other K2200 variants such as K2200G or K2200S, provided the package type change is acceptable. Alternative parts must match the 205V-230V breakover voltage range and 180V blocking voltage. Verify lead form compatibility if replacing the TO-92 package with a different footprint.
