Siemens D165G200-12-MREQ Drive Transistor Module

Siemens D165 G200-12 MREQ Drive Transistor Module is a high-power transistor block designed for Siemens SIMOREG D165/G200 servo drive systems. Identified as D165 G200-12 MREQ, its catalog designation 6RB 2012-2EA00 marks its place in Siemens' SIMOREG power-electronics family. This module forms the drive's transistor switching stage, coordinating with other power and control modules to convert the DC link voltage into controlled motor current for precise torque and speed regulation. As part of the SIMOREG D165/G200 family, it is designed for use in Siemens servo-drive configurations where modular power blocks are paired with amplifiers and control logic to deliver reliable motor performance. The D165 G200-12 MREQ designation is widely referenced in Siemens-distributor literature and in third-party listings as the original Siemens transistor module used in these drives. Compatible with the D165 and G200 servo-drive architectures, this module represents the subassembly that handles high-speed switching functions essential to servo control. When sourced as an original Siemens component with the 6RB 2012-2EA00 code, it supports ongoing maintenance and refurbishment of SIMOREG drives that rely on the D165/G200 platform.
