K1100E70RP2

Overview

The Littelfuse K1100E70RP2 is a standard bidirectional SIDAC (Silicon Bidirectional Trigger Device) belonging to the Kxxxzy series. It functions as a silicon bilateral voltage-triggered switch housed in a TO-92 package with Type 70 lead form, supplied in a reel pack configuration. The device features a glass-passivated junction for ruggedness and RoHS compliance. Key electrical parameters include a breakover/trigger voltage range of 104V to 118V and a repetitive peak off-state voltage of 90V. It supports an on-state RMS current of 1A at 50/60Hz and can withstand a peak non-repetitive surge current of 20A for a single cycle at 60Hz. The component operates within a junction temperature range of -40°C to 125°C.

Feature Summary

• Glass-passivated junctions ensure rugged performance and dependability in harsh environments.
• Bidirectional switching capability suitable for AC circuit applications.
• RoHS compliant construction utilizing matte tin plated terminals.

Applications

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

Procurement Notes

Verify the specific ordering suffix RP2 confirms the TO-92 package with Type 70 lead form and reel packaging. Confirm the voltage rating code '110' corresponds to the required 104V to 118V breakover range. Ensure the application environment remains within the specified thermal limits and that surge currents do not exceed the rated ITSM values to prevent device failure.

Selection Notes

Select this component when a trigger voltage between 104V and 118V is required for AC triggering circuits. The TO-92 package is appropriate for through-hole mounting where space allows. Consider the 1A RMS current rating for load handling. Verify that the 90V blocking voltage meets the circuit's off-state requirements. Compare against other Kxxxzy variants if different voltage thresholds or package types are needed.

Part Context

This part belongs to the Littelfuse Kxxxzy Series of Standard Bidirectional SIDACs. The series offers various breakover voltages from 79V to 330V across multiple packages including DO-15, DO-214, and TO-92. The 'K1100' designation specifically identifies the 104V-118V trigger voltage variant within this broad family of silicon voltage-triggered switches designed for high-voltage triggering applications.

Replacement Considerations

Compatible substitutes within the same series include K1100E70 (bulk), K1100E70AP (ammo pack), and K1100E70RP3 (reel). Other voltage variants like K1050E70RP2 or K1200E70RP2 may be used if the trigger voltage range aligns with circuit requirements. Ensure any replacement maintains the TO-92 package and Type 70 lead form for mechanical compatibility.
