K2200GAP

Overview

The Littelfuse K2200GAP is a high-voltage trigger diode (SIDAC) from the Kxxxzy series, designed for breakover switching applications. It utilizes a DO-15 through-hole package and operates within a temperature range of -40°C to +150°C. The device features a nominal breakover voltage of 220V with a tolerance of ±10%, resulting in a range of 205V to 230V. It supports an RMS current rating of 1A and can handle non-repetitive peak on-state currents of 16.7A or 20A depending on pulse duration. The component is supplied in an Ammo Pack configuration.

Feature Summary

• Provides bidirectional breakover switching for triggering circuits
• Engineered for robust overvoltage protection in AC/DC systems
• Utilizes a standard through-hole DO-15 axial lead package

Applications

• Triggering circuits for thyristors and triacs
• High-pressure sodium lamp ignition
• Xenon flash ignition systems
• Natural gas igniters

Procurement Notes

Verify the specific suffix 'GAP' to confirm the Ammo Pack packaging format, as other suffixes indicate different handling methods like bulk or reel. Ensure the order quantity aligns with the manufacturer's minimum order requirements for this specific packaging type. Cross-reference the Littelfuse Teccor branding to confirm authenticity and traceability against official component databases before finalizing procurement.

Selection Notes

Select the K2200GAP when a DO-15 through-hole form factor is required for high-voltage trigger applications. This model is appropriate for designs needing a 220V nominal breakover voltage with ±10% tolerance. Consider the 1A RMS current rating and thermal limits up to 150°C to ensure compatibility with the target circuit's power dissipation and environmental operating conditions.

Part Context

This component belongs to the Kxxxzy SIDAC family manufactured by Littelfuse under the Teccor brand. These silicon unilateral voltage-triggered switches are rectified AC/DC circuit oriented devices. The K2200GAP specifically represents the axial lead variant within this series, distinct from surface-mount options like the K2200S1URP which uses a DO-214AC package.

Replacement Considerations

The K2200G is a related part number within the same series but differs in packaging, typically offered in Bulk rather than Ammo Pack. Verify that the functional electrical parameters remain identical if substituting based on packaging availability.
