MCR12DSN-001

Overview

The MCR12DSN-001 is a Silicon Controlled Rectifier (SCR) manufactured by onsemi, classified as a reverse blocking thyristor with sensitive gate characteristics. It is housed in an IPAK through-hole package and rated for a maximum repetitive peak reverse voltage of 800 V. The device supports a continuous on-state current of 12 A RMS at 80°C and features a high surge current capability of 100 A. Designed for industrial and consumer applications, it offers glass passivated junctions for reliability and high immunity to dv/dt, specified at a minimum of 100 V/μsec at 125°C.

Feature Summary

• Sensitive gate design facilitates ease of triggering and circuit integration
• Glass passivated junctions ensure uniformity and long-term reliability
• High dv/dt immunity prevents false triggering under rapid voltage transients
• Robust surge current handling capability supports high-power switching demands

Applications

• Half-wave AC control circuits
• Motor control systems
• Heating control applications
• General-purpose power supplies

Procurement Notes

Verify the specific suffix -001 against official onsemi documentation to confirm exact material composition and compliance status. Ensure the procurement channel provides valid traceability for the IPAK package variant. Cross-reference the datasheet revision to confirm the presence of lead-free packaging options if required by project specifications. Confirm that the sensitive gate parameters match the design requirements for the intended trigger circuitry.

Selection Notes

Select this component when a high-voltage, high-current SCR is required for half-wave AC applications. The sensitive gate feature simplifies drive circuit design compared to standard gate devices. Consider the IPAK package for through-hole mounting constraints and thermal management needs. Evaluate the 100 A surge rating against potential inrush currents in motor or heating loads to ensure device survival during startup conditions.

Part Context

This part belongs to the MCR series of Silicon Controlled Rectifiers from onsemi, designed primarily for robust industrial and consumer power control tasks. The MCR12DSN-001 variant specifically utilizes the IPAK package, offering a compact yet rugged solution for medium-power applications. It shares functional similarities with other MCR family members but is distinguished by its specific gate sensitivity and packaging configuration.

Replacement Considerations

The MCR12DSN-1G is a comparable variant within the same product line. Verify pinout compatibility and electrical parameter equivalence before substitution. Ensure the replacement part meets the same sensitive gate requirements and thermal performance standards for the target application.
