K2200SRP

Overview

The K2200SRP is a high-voltage trigger diode (SIDAC) manufactured by Littelfuse, designed for overvoltage protection in electronic circuits. It operates within the Kxxx0yU series and utilizes a DO-214AC (SMB) surface-mount package. Key electrical parameters include a breakover voltage (VBO) of 230 V and a rated repetitive off-state voltage (VDRM) of 190 V. The device supports an RMS on-state current (It RMS) of 1 A and can handle non-repetitive on-state currents ranging from 16.7 A to 20 A. It functions within a temperature range of -40°C to +150°C, with a maximum holding current (Ih) of 80 mA and an on-state voltage of 1.2 V.

Feature Summary

• Provides bidirectional high-voltage triggering for circuit protection applications
• Utilizes a compact surface-mount DO-214AC package for automated assembly
• Capable of handling significant non-repetitive surge currents for robust transient suppression

Applications

• Overvoltage protection for sensitive electronic components
• Triggering devices for thyristors and triacs
• Surge protection in AC power lines

Procurement Notes

Verify the specific suffix 'RP' against the manufacturer's latest documentation to confirm packaging details, such as reel quantity and tape specifications. Ensure compatibility with standard SMB footprint dimensions during PCB layout. Confirm RoHS compliance status through official Littelfuse declarations prior to final component selection.

Selection Notes

Select this component when a breakover voltage near 230 V is required for bidirectional triggering. The 1 A RMS current rating suits moderate load applications. Verify that the DO-214AC package fits the available board space. Consider the thermal management requirements given the wide operating temperature range up to +150°C.

Part Context

This part belongs to the Littelfuse SIDAC family, specifically the K-series designed for high-voltage switching. These devices are distinct from standard Zener diodes due to their symmetrical breakdown characteristics and higher current handling capabilities. They serve as critical elements in transient voltage suppression networks.

Replacement Considerations

Cross-reference with other SIDACs offering similar 230 V breakover voltages and SMB packages. Ensure substitute parts match the 1 A RMS current rating and hold-off voltage specifications to maintain circuit integrity.
