K2200GRP

Overview

The Littelfuse K2200GRP is a high-voltage trigger diode, classified as a SIDAC within the Teccor family. It features a DO-15 through-hole package and operates with a breakover voltage of 230 V and a rated repetitive off-state voltage of 190 V. The device supports an RMS on-state current of 1 A and handles non-repetitive on-state currents up to 20 A. It maintains a low holding current of 80 mA maximum and exhibits an on-state voltage of 1.2 V. The component functions reliably across a temperature range from -40°C to +150°C.

Feature Summary

• Symmetric bidirectional switching capability for AC circuit triggering
• High surge current handling capacity for transient protection applications
• Robust thermal performance suitable for elevated operating environments

Applications

• Triggering silicon-controlled rectifiers (SCRs) in power control circuits
• Overvoltage protection in AC mains-powered equipment
• Phase control applications in lighting and motor speed regulation systems

Procurement Notes

Verify the specific suffix against manufacturer documentation to confirm package type and tape/reel specifications. Ensure the ordering code matches the required DO-15 axial lead configuration. Confirm RoHS compliance status directly with the supplier or official datasheet before finalizing procurement orders.

Selection Notes

Select this component when a symmetric high-voltage trigger device is required for SCR gate driving. Verify that the 190 V off-state rating aligns with the system's peak line voltage. Ensure the PCB layout accommodates the DO-15 axial leads and provides adequate creepage distance for the high blocking voltage.

Part Context

This part belongs to the Kxxx0yU series of high-voltage trigger diodes manufactured by Littelfuse under the Teccor brand. These devices are designed specifically for triggering SCRs and TRIACs in AC power control applications. The series offers various voltage ratings and package options to suit different circuit density and power requirements.

Replacement Considerations

Cross-reference with other K2200 variants such as K2200GURP for identical electrical characteristics but potential packaging differences. Verify pinout compatibility and physical dimensions before substituting any alternative high-voltage trigger diodes.
