Overview
The Littelfuse SV8012DTP is a Silicon Controlled Rectifier (SCR) designed for high-temperature and high dv/dt applications. It features an 800 V rated repetitive off-state voltage and conducts a 12 A RMS on-state current. The device operates within a junction temperature range of -40 °C to +150 °C. Packaged in a TO-252-3 surface-mount case, it offers a non-repetitive peak on-state current of 120 A and a maximum holding current of 40 mA. Gate triggering requires a maximum DC current of 20 mA.
Feature Summary
- High thermal stability with operation up to 150 °C
- Robust performance under rapid voltage transients
- Surface-mount construction for automated assembly
Applications
- Industrial motor control systems
- High-temperature power regulation circuits
- Solid-state switching applications
Procurement Notes
Verify the specific suffix DTP against official Littelfuse documentation to confirm the exact package variant and tape-and-reel specifications. Ensure that the ordering information matches the required surface-mount configuration and compliance standards before finalizing procurement orders.
Selection Notes
Select this component when an SCR with 800 V blocking capability and 12 A continuous current handling is required in a compact surface-mount form factor. Confirm that the gate drive circuit can supply at least 20 mA and that the system environment supports the specified 150 °C maximum operating temperature.
Part Context
This part belongs to the SV series of thyristors from Littelfuse, which are engineered for demanding environments requiring high thermal endurance and immunity to voltage spikes. The SV8012DTP shares core electrical characteristics with other members of the SVxx12xx family but utilizes a distinct surface-mount package suitable for PCB integration.
Replacement Considerations
Direct substitutes include the S8012DTP, which shares identical electrical ratings but may differ in specific package tolerances or manufacturing revisions. Verify pinout compatibility and thermal resistance values before implementing any cross-reference.
