K2200F23

Overview

The Littelfuse K2200F23 is a high-voltage trigger diode, classified as a SIDAC within the thyristor product category. Manufactured by Littelfuse under the Teccor brand, this component utilizes a DO-15 through-hole package for circuit integration. It features a breakover voltage (VBO) range of 205 V to 230 V and a rated repetitive off-state voltage (VDRM) of 180 V. The device supports an RMS on-state current (It RMS) of 1 A and can handle non-repetitive on-state currents up to 16.7 A or 20 A. Operating temperatures range from -40°C to +85°C, with a maximum holding current of 150 mA and an on-state voltage of 1.5 V.

Feature Summary

• High-voltage triggering capability designed for precise circuit activation
• Robust construction in a standard through-hole DO-15 package
• Symmetrical bidirectional switching characteristics typical of SIDAC devices

Applications

• Triggering circuits for silicon-controlled rectifiers (SCRs)
• Protection of sensitive electronic components against voltage transients
• Gate drive applications in AC power control systems

Procurement Notes

Verify the specific suffix 'F23' against official Littelfuse documentation to confirm exact tolerance and packaging specifications. Ensure compatibility with DO-15 through-hole mounting requirements. Confirm RoHS and REACH compliance status via the manufacturer's datasheet before procurement. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select the K2200F23 when a breakover voltage between 205 V and 230 V is required for gate triggering. Consider the 1 A RMS current rating for load capacity. Evaluate the DO-15 package size against available PCB space. Compare the 150 mA holding current against circuit leakage to ensure reliable latching behavior during operation.

Part Context

This component belongs to the Kxxxzy series of high-voltage trigger diodes produced by Littelfuse. It shares functional similarities with other SIDAC devices in the Teccor portfolio, such as the K2200G, which also utilizes a DO-15 package but may differ in specific electrical tolerances or manufacturing batches. The series is designed for robust industrial and consumer electronics protection.

Replacement Considerations

The K2200G is a documented alternative within the same Littelfuse family, sharing the DO-15 package and similar electrical characteristics. Verify that the breakover voltage ranges and current ratings of any substitute part match the original design requirements.
