K2200F1

Overview

The Littelfuse K2200F1 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 PCB mounting. 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 handles non-repetitive on-state currents up to 16.7 A or 20 A depending on specific conditions. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Provides bidirectional switching characteristics for triggering applications
• Designed for high-voltage circuit protection and pulse generation
• Utilizes glass passivated junction technology for reliability

Applications

• Triggering silicon controlled rectifiers (SCRs) and triacs
• Pulse generation circuits in timing applications
• Overvoltage protection in AC power line interfaces

Procurement Notes

Verify the exact suffix designation when ordering, as Littelfuse offers variations such as K2200G and K2200S1URP with different packages and electrical tolerances. Confirm RoHS compliance status directly with the manufacturer or authorized distributors prior to procurement. Ensure the selected variant matches the required thermal management and mounting style for the specific design implementation.

Selection Notes

Select the K2200F1 based on its 180 V VDRM rating to ensure it remains off during normal operation while triggering at the desired threshold. Compare the 1 A RMS current capability against the load requirements to prevent device failure. Consider the DO-15 package dimensions for board space constraints and verify that the operating temperature range meets the environmental conditions of the final assembly.

Part Context

This component belongs to the Kxxxzy series of high-voltage trigger diodes from Littelfuse. It is part of the broader Teccor family of thyristors designed for robust performance in industrial and consumer electronics. The K2200F1 shares functional similarities with other parts in the K2200 series but differs in packaging and specific parameter tolerances compared to surface-mount variants like the K2200S1URP.

Replacement Considerations

Direct substitutes include the K2200G, which shares the DO-15 through-hole package and similar electrical characteristics. Designers should verify that the replacement part's breakover voltage tolerance and holding current match the original circuit requirements to maintain proper functionality.
