K2500G

Overview

The Littelfuse K2500G is a silicon bilateral voltage-triggered switch (SIDAC) from the Kxxxzy series, housed in a DO-15 package. It features a breakover voltage range of 240 V to 280 V and a repetitive peak off-state voltage of 200 V. The device supports an on-state RMS current of 1 A at 50/60 Hz and can withstand a peak non-repetitive surge current of 20 A for a single cycle at 60 Hz. 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 transition
Glass-passivated junctions for environmental reliability
RoHS compliant construction

Applications

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

Procurement Notes

Verify the specific suffix 'G' corresponds to the DO-15 through-hole package configuration required for your design. Confirm that the standard circuit function meets the application needs, as other variants exist. Ensure the ordering quantity aligns with the bulk packaging specifications provided by authorized distributors.

Selection Notes

Select this component when a breakover voltage between 240 V and 280 V is required for AC circuits. Ensure the peak off-state voltage rating of 200 V exceeds the maximum steady-state voltage in the application. Verify that the thermal management allows the junction temperature to remain within the specified -40°C to 125°C operational limits during continuous conduction.

Part Context

The K2500G belongs to the Kxxxzy SIDAC family manufactured by Littelfuse. This series includes various voltage ratings and package options such as DO-214 and TO-92. The 'K' prefix identifies the device type as a SIDAC, while '250' indicates the specific voltage class within the product line.

Replacement Considerations

Cross-reference with other K2500zy variants if different packages are needed. Verify that substitute components match the 240 V to 280 V breakover voltage range and the 1 A RMS current rating to maintain circuit performance.
