SJ4012VTP

Overview

The SJ4012VTP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse, designed for high-temperature and high dv/dt applications. It features an RMS on-state current of 12 A and a rated repetitive peak off-state voltage of 400 V. The device operates within a temperature range of -40°C to +150°C and utilizes a TO-220-2 through-hole package. Key electrical characteristics include a maximum holding current of 75 mA and a non-repetitive peak on-state current capability of 300 A.

Feature Summary

High-temperature operation up to 150°C
High dv/dt capability for robust switching
Glass-passivated junctions for parameter stability

Applications

AC power control circuits
Industrial motor drives
Power supply regulation

Procurement Notes

Verify the specific suffix 'VTP' against the official Littelfuse datasheet to confirm pinout and thermal specifications. Ensure the ordering quantity aligns with manufacturer tube packaging requirements. Confirm RoHS compliance status directly from the product specification document before finalizing procurement.

Selection Notes

Select this component when a 400 V blocking voltage and 12 A continuous current are required in a TO-220-2 package. Verify that the gate trigger current and holding current parameters meet the driving circuit constraints. Ensure the application environment supports the specified maximum operating temperature of 150°C.

Part Context

This part belongs to the SJxx20xx series of Thyristors produced by Littelfuse. It shares similar electrical ratings with other variants in the family but differs in package type and specific thermal or triggering characteristics defined by its unique model designation.

Replacement Considerations

Cross-reference with SJ4020RTP or SJ4020N2RP for alternative packages. Verify that the replacement SCR maintains equivalent voltage and current ratings. Confirm pin compatibility and thermal resistance values match the existing design constraints.
