STP802U2SRP

Overview

The STP802U2SRP is a sensitive dual Silicon Controlled Rectifier (SCR) manufactured by IXYS, designed for surface-mount applications. It features an 800 V rated repetitive off-state voltage and supports a continuous on-state RMS current of 1.5 A. The device utilizes an SOP-8 package configuration, providing independent control channels within a compact form factor. Key electrical characteristics include a maximum gate trigger voltage of 800 mV and a short turn-off time, ensuring rapid switching capabilities. This component is engineered to deliver high static dv/dt immunity, making it suitable for environments requiring reliable phase control and efficient power management in modern electronic systems.

Feature Summary

• Dual-channel SCR architecture with independent gate control for precise signal processing
• High static dv/dt capability ensures stable operation against rapid voltage transients
• Short turn-off time enables fast switching performance for dynamic circuit requirements
• Surface-mount SOP-8 packaging facilitates automated assembly and space-constrained designs

Applications

• Phase control circuits in AC power regulation systems
• Sensitive switching applications requiring high noise immunity
• Industrial motor control interfaces
• Solid-state relay driver stages

Procurement Notes

Verify the specific manufacturer part number STP802U2SRP against official IXYS documentation to confirm pinout compatibility and thermal specifications. Ensure that the sourcing channel provides valid traceability for the SOP-8 package variant. Cross-reference the datasheet for any recent production changes or environmental compliance updates prior to final integration into the design.

Selection Notes

Select this component when dual independent SCR functionality is required in a surface-mount format. The 1.5 A RMS rating and 800 V blocking voltage define its operational limits. Consider the short turn-off time and high dv/dt sensitivity as critical factors for high-frequency or noisy environments where standard SCRs might fail to latch or commutate correctly.

Part Context

This device belongs to IXYS' family of sensitive dual SCRs, specifically optimized for surface-mount technology. It complements other IXYS thyristor products like the S802CS2RP but offers dual-channel isolation in an SOP-8 footprint. The series is designed to replace through-hole equivalents in modern PCB layouts while maintaining robust electrical performance for industrial and consumer power applications.
