SV8012VTP

Scrs Overview

The Littelfuse SV8012VTP is a Silicon Controlled Rectifier (SCR) designed for high-temperature and high dv/dt applications. It features an RMS on-state current of 12 A and a rated repetitive off-state voltage of 800 V. The device operates within a junction temperature range of -40°C to +150°C and utilizes a TO-251-3 package for through-hole mounting. Key electrical characteristics include a maximum gate trigger current of 20 mA, a holding current of 40 mA, and a non-repetitive peak on-state current of 144 A.

Scrs Feature Summary

• Engineered for high junction temperature operation up to 150°C
• Optimized for high dv/dt performance in demanding environments
• Low gate trigger current facilitates efficient control circuitry

Scrs Applications

• Phase control in heating systems
• Motor speed controls
• Converters and rectifiers
• Inrush current control
• Capacitive discharge ignitions

Scrs Procurement Notes

Verify the specific suffix 'VTP' against the manufacturer's official datasheet to confirm the exact packaging configuration and terminal finish. Ensure that the TO-251-3 through-hole variant matches the intended PCB layout requirements. Cross-reference the part number with Littelfuse documentation to validate RoHS compliance status and current production lifecycle stage before finalizing procurement plans.

Scrs Selection Notes

Select this component when an SCR requires robust performance under high thermal stress and rapid voltage transitions. The 12 A RMS rating suits moderate power switching tasks. Verify that the 800 V blocking voltage aligns with the system's peak reverse voltage demands. Consider the TO-251-3 package constraints for thermal management and mechanical mounting space availability in the design.

Scrs Part Context

This device belongs to the SVxx12xx series from Littelfuse, which specializes in high junction temperature SCRs. The series is engineered for uni-directional switching applications requiring reliability in harsh conditions. The SV8012VTP specifically addresses needs for high dv/dt immunity and elevated operating temperatures compared to standard thyristors.

Scrs Replacement Considerations

Consult Littelfuse documentation for direct cross-references. Potential alternatives within the same series may include variants with different voltage ratings or packages, such as SV6012L1TP for lower voltage applications.
