K0900SRP

Overview

The Littelfuse K0900SRP is a high-voltage trigger diode, classified as a SIDACtor within the Kxxxzy series. It features a DO-214 surface-mount package and operates in a temperature range of -40°C to +85°C. The device has a rated repetitive off-state voltage (VDRM) of 70 V and a breakover voltage (VBO) ranging from 79 V to 97 V. Key electrical parameters include a maximum breakover current (IBO) of 10 µA, an on-state voltage of 1.5 V, and a holding current (Ih) maximum of 150 mA. It supports a non-repetitive on-state current of 20 A and an RMS on-state current (It RMS) of 1 A.

Feature Summary

• Provides bidirectional switching characteristics for triggering applications
• Designed for surface-mount integration via DO-214 packaging
• Capable of handling high peak currents for pulse generation

Applications

• Triggering silicon-controlled rectifiers (SCRs)
• Generating pulses for thyristor gates
• High-voltage protection circuits requiring precise breakdown thresholds

Procurement Notes

Verify the specific suffix 'SRP' against official Littelfuse documentation to confirm surface-mount reel packaging requirements. Ensure the component meets RoHS and REACH standards for the target market. Cross-reference the DO-214 footprint with PCB layout guidelines to guarantee proper soldering and thermal performance during assembly.

Selection Notes

Select this component when a surface-mount solution is required for high-voltage triggering applications. Compare the 79 V to 97 V breakover voltage range against circuit requirements to ensure accurate triggering. Verify that the 1 A RMS current rating aligns with the load demands and that the operating temperature range covers the environmental conditions.

Part Context

The K0900SRP belongs to the Littelfuse K-series of SIDACtors, which are symmetric trigger devices used for overvoltage protection and pulse generation. This series offers robust performance in harsh environments. The SRP suffix typically denotes a specific tape-and-reel packaging format suitable for automated surface-mount assembly processes.

Replacement Considerations

Consult Littelfuse official substitution guides for compatible SIDACtors with similar VBO ranges and DO-214 packages. Verify pinout compatibility and thermal characteristics before replacing the original component.
