Scrs datasheet and documents for SK015L

SK015L

Scrs Overview

The Littelfuse SK015L is a Silicon Controlled Rectifier (SCR) rated for 1000V repetitive peak reverse voltage and 15A average on-state current. It utilizes a TO-220AB flange mount package with an isolated case connection, facilitating direct heatsink attachment without external insulators. Key electrical characteristics include a maximum DC gate trigger current of 30 mA, a holding current of 40 mA, and a non-repetitive peak surge current capability of 225 A. The device features a critical rate of rise of off-state voltage (dv/dt) of 200 V/µs and complies with RoHS standards.

Scrs Feature Summary

Isolated flange mount construction eliminates the need for separate insulating hardware during installation.

Scrs Applications

Industrial motor control circuits
High-voltage power supply regulation
AC phase control applications

Scrs Procurement Notes

Verify the specific suffix against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging variations. Ensure the procurement documentation explicitly lists the TO-220AB package style and isolated tab configuration to match design requirements. Confirm RoHS compliance status through the supplier's certificate of conformity prior to ordering.

Scrs Selection Notes

Select this component when a high-voltage SCR requires an electrically isolated mounting surface for efficient thermal management. The 15A current rating suits moderate power industrial loads, while the 1000V blocking voltage provides safety margin in mains-connected systems. Verify that the gate trigger parameters align with the driving circuit's output capabilities.

Scrs Part Context

This part belongs to the Littelfuse SCRs product line, designed for robust switching in power electronics. The SK series typically offers standard silicon rectification capabilities within the TO-220 form factor, balancing current handling with compact thermal solutions for chassis-mounted applications.

Scrs Replacement Considerations

Consult Littelfuse official substitution guides for compatible SCRs with matching voltage, current, and package specifications. Generic replacements must maintain the isolated flange mount configuration to ensure proper grounding and thermal interface compatibility.
