Overview
The SCT151K-800R is a silicon controlled rectifier manufactured by SMC Diode Solutions. It features an 800 V maximum repetitive peak off-state voltage and a 12 A average on-state current rating. The device utilizes a DPAK surface-mount package, specifically TO-252-3 with a tab connection. It operates within a junction temperature range of -55°C to 150°C and complies with RoHS3 standards.
Feature Summary
- High surge current capability designed to withstand shock loading associated with large currents.
- Surface mount construction in a DPAK package for efficient PCB integration.
Applications
- General purpose switching applications
- Power control circuits requiring high surge tolerance
Procurement Notes
Verify the specific suffix 'K' against the manufacturer datasheet to confirm exact mechanical or electrical variations. Ensure the DPAK footprint matches the design layout. Confirm RoHS3 compliance requirements align with project specifications before finalizing procurement orders.
Selection Notes
Select this component when a surface-mount SCR with 800V blocking capability and 12A continuous current is required. The DPAK package offers a compact solution for power management designs. Evaluate thermal dissipation needs relative to the package's heat sinking capabilities through the tab connection.
Part Context
This part belongs to the SCT151 series of silicon controlled rectifiers from SMC Diode Solutions. The series is characterized by its ability to handle significant current shocks. The SCT151K-800R variant specifically addresses higher voltage applications compared to lower-rated siblings in the same family.
Replacement Considerations
Direct substitutes include other 800V, 12A SCRs in DPAK packages from various manufacturers. Verify pinout compatibility and thermal resistance values when considering alternative sources for supply chain resilience.
