SV8012DRP

Overview

The Littelfuse SV8012DRP is a Silicon Controlled Rectifier (SCR) from the SVxx12xx series, designed for high-temperature and high dv/dt applications. It features an 800 V rated repetitive off-state voltage (VDRM) and conducts a continuous RMS on-state current of 12 A. The device utilizes a TO-252-3 surface-mount package and operates within a temperature range of -40°C to +150°C. Key electrical parameters include a gate trigger current of 20 mA, a holding current maximum of 40 mA, and a non-repetitive peak on-state current of 144 A.

Feature Summary

• Engineered for high-temperature environments with operation up to +150°C
• Optimized for high dv/dt immunity in demanding power circuits
• Surface-mount construction in a compact TO-252-3 package

Applications

• High-temperature industrial power control systems
• Circuits requiring robust dv/dt performance
• Automotive and heavy-duty equipment power management

Procurement Notes

Verify the specific suffix DRP against official Littelfuse documentation to confirm reel packaging and quantity specifications. Ensure the component matches the required thermal and electrical ratings for the target application before procurement.

Selection Notes

Select this SCR when high junction temperature tolerance and rapid voltage change immunity are critical. Compare the 800 V blocking capability and 12 A RMS rating against circuit requirements to ensure adequate margin for load conditions.

Part Context

This component belongs to the SVxx12xx family of thyristors, which are specialized for harsh operating conditions. The SV8012DRP variant specifically addresses needs for high thermal stability and transient voltage resilience in surface-mount designs.

Replacement Considerations

Consult Littelfuse datasheets for direct pin-compatible alternatives within the SV series or S series that match the 800 V and 12 A specifications.
