MCMA260P1600YA

Overview

The MCMA260P1600YA is a dual silicon controlled rectifier module manufactured by IXYS. It features a flange mount configuration with seven pins and an isolated case connection. The device supports a repetitive peak reverse voltage of 1600 V and a rated RMS on-state current of 260 A. Non-repetitive surge current capability reaches 8.97 kA. Maximum DC gate trigger current is specified at 150 mA, with a maximum DC gate trigger voltage of 3 V. The internal structure consists of two series-connected elements in a center-tap arrangement. Operating temperature ranges from -40 °C to +140 °C.

Feature Summary

• Dual element construction configured for series connection with center tap topology
• Isolated ceramic metal-sealed cofired package design for panel mounting
• High surge current handling capability suitable for demanding power applications

Applications

• Industrial motor drive systems requiring high current thyristor control
• Power conversion circuits utilizing phase leg configurations
• Heavy duty rectification setups involving center-tapped transformer arrangements

Procurement Notes

Verify the specific suffix YA against official datasheets to confirm pinout and terminal descriptions match your mechanical constraints. Confirm RoHS compliance status through manufacturer documentation before integration. Ensure thermal management solutions accommodate the flange mount requirement and maximum operating temperature limits defined in the technical specifications.

Selection Notes

Select this component when designing circuits requiring dual SCR elements within a single isolated package. The center-tap configuration suits applications needing balanced current distribution across two series-connected devices. Verify that the 1600 V blocking voltage aligns with system peak reverse voltage requirements. Check that gate drive capabilities can supply the necessary trigger current without exceeding maximum ratings.

Part Context

This part belongs to the IXYS MCMA series of thyristor modules designed for industrial power electronics. The series offers various current and voltage ratings packaged in standardized form factors like TO-240 variants. These modules are engineered for robust performance in high-power environments where reliable switching and isolation are critical for system safety and efficiency.
