S4X8BSRP

Overview

The S4X8BSRP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse. It features an 800V repetitive peak reverse voltage rating and a holding current of 200µA. The device supports a maximum RMS on-state current of 0.8A. It is supplied in a DO-214AC (SMB) surface-mount package, designated by the 'SRP' suffix. This component is designed for applications requiring compact overcurrent protection and switching capabilities within defined electrical limits.

Feature Summary

Surface-mount construction for automated assembly
High-voltage blocking capability
Low holding current sensitivity

Applications

Overcurrent protection circuits
Solid-state switching applications
Industrial control systems

Procurement Notes

Verify the complete part number including the 'SRP' suffix to ensure the correct DO-214AC surface-mount package configuration. Confirm that the 0.8A RMS current and 800V voltage ratings align with the specific circuit requirements before procurement. Ensure compatibility with standard surface-mount reflow soldering profiles during integration.

Selection Notes

Select this component when a low-profile SCR is required for high-voltage applications. The 200µA holding current allows for sensitive triggering mechanisms. Verify thermal management needs for the SMB package under continuous load conditions. Ensure the gate trigger characteristics match the driving circuit's output capabilities for reliable operation.

Part Context

This device belongs to Littelfuse's general-purpose SCR portfolio. It provides a robust solution for power control tasks where space constraints necessitate surface-mount technology. The series offers standardized electrical parameters suitable for various industrial and commercial power electronics designs.

Replacement Considerations

Consult official Littelfuse documentation for verified cross-reference data. Do not substitute based solely on similar voltage or current ratings without verifying package dimensions and thermal characteristics.
