Product Overview

The MGJ1D051505MPC-R7 is a 5.7kVDC high-isolation 1W Surface Mount (SM) gate drive DC-DC converter launched by Murata, specifically designed for IGBT, SiC, and MOSFET gate drive applications. With a nominal input voltage of 5V, bipolar output configuration of ±15V/-5V, and output current of 50mA per channel, it delivers a stable output power of 1W. Featuring a 5.7kVDC isolation test voltage and reinforced insulation design, it complies with UL62368-1 and ANSI/AAMI ES60601-1 2MOPP certifications. Equipped with an ultra-low isolation capacitance of 3pF and a wide operating temperature range of -40℃~105℃, it is an ideal gate power supply solution for high-voltage scenarios such as industrial motor drives, inverters, and renewable energy equipment.

Technical Specifications

Typical Applications

• IGBT/SiC Gate Drive: The +15V/-5V bipolar output perfectly matches the gate drive voltage requirements of IGBT and SiC devices. The 5.7kVDC high isolation performance suppresses high-voltage side interference, and the ultra-low 3pF capacitance reduces common-mode noise, ensuring accurate transmission of drive signals.
• Industrial Motor Drives & Inverters: The wide operating temperature range (-40℃~105℃) adapts to harsh industrial environments. The reinforced insulation design meets the safety requirements of high-voltage systems, and the compact SM package fits the high-density PCB layout of inverters. The short-circuit protection function improves the stability of motor drive systems.
• Renewable Energy Equipment: The high isolation voltage adapts to high-voltage scenarios such as photovoltaic inverters and wind power converters. The bipolar output drives power devices, and the ultra-low isolation capacitance reduces energy loss. RoHS compliance meets the environmental requirements of green energy equipment.
• Medical Equipment Auxiliary Power Supply: 2MOPP protection meets the ANSI/AAMI ES60601-1 medical safety standard. High isolation performance prevents electric shock risks for medical staff and patients, and stable output provides reliable power supply for power drive circuits in medical equipment.
• Industrial Power Supplies & Automation Equipment: The 5V input adapts to common industrial low-voltage power supply systems. The dual-output configuration simplifies the design of gate drive circuits. The surface-mount process facilitates automated mass production, and multiple protection mechanisms reduce equipment failure rates.
