PRODUCT OVERVIEW
Offering Three isolated output voltages of 24V,
the MGJ6 series of DC-DC converters is ideal for
simultaneously powering ‘high side’ and ‘low side’
gate drive circuits for IGBTs, Silicon and Silicon
Carbide Mosfets in full bridge circuits.The MGJ6
series is characterised for high isolation and dv/dt
requirements commonly seen in bridge circuits used
in motor drives and inverters.

TECHNICAL NOTES
ISOLATION VOLTAGE
‘Hi Pot Test’, ‘Flash Tested’, ‘Withstand Voltage’, ‘Proof Voltage’, ‘Dielectric Withstand Voltage’ & ‘Isolation Test Voltage’ are all terms that relate to the same thing, a test
voltage, applied for a specified time, across a component designed to provide electrical isolation, to verify the integrity of that isolation.
Murata Power Solutions MGJ6 series of DC-DC converters are all 100% production tested at 4kVACrms for 1 second from input to output and 2.5kVACrms for 1 second
from output to output. Also they are all qualification tested at 5.7kVDC for 1 minute from input to output and 3kVDC for 1 minute from output to output.
A question commonly asked is, “What is the continuous voltage that can be applied across the part in normal operation?”
When the insulation in the MGJ6 series is not used as a safety barrier , i.e. provides functional isolation only, continuous or switched voltages across the barrier up to
3kV are sustainable. Long term reliability testing at these voltages continues. Peak Inception voltages measured were in excess of 3.5kV when testing for partial dis-
charge in accordance with IEC 60270. Please contact Murata for further information.
The MGJ6 series is pending recognition by Underwriters Laboratory to 250 Vrms Reinforced Insulation, please see safety approval section below.
REPEATED HIGH-VOLTAGE ISOLATION TESTING
It is well known that repeated high-voltage isolation testing of a barrier component can actually degrade isolation capability, to a lesser or greater degree depending on
materials, construction and environment. We therefore strongly advise against repeated high voltage isolation testing, but if it is absolutely required, that the voltage be
reduced by 20% from specified test voltage.
SAFETY APPROVAL
ANSI/AAMI ES60601-1
The MGJ6 series is pending recognition ANSI/AAMI ES60601-1.
UL 60950
The MGJ6 series is pending recognition by Underwriters Laboratory (UL) to UL 60950 for reinforced insulation to a working voltage of 250Vrms with a maximum measured product
operating temperature of 105°C.
Creepage and clearance 8mm, input to output & across outputs.
FUSING
The MGJ6 Series of converters are not internally fused so to meet the requirements of UL an anti-surge input line fuse should always be used with ratings as defined below.
Input Voltage, 5V 4A
Input Voltage, 12V 2A
Input Voltage, 24V 1A
All fuses should be UL recognized, 250Vac rated.
CHARACTERISATION TEST METHODS
Ripple & Noise Characterisation Method
Ripple and noise measurements are performed with the following test configuration.
C1
1μF X7R multilayer ceramic capacitor, voltage rating to be a minimum of 3 times the output voltage of the DC-DC converter
10μF tantalum capacitor, voltage rating to be a minimum of 1.5 times the output voltage of the DC-DC converter with an ESR of less
C2
than 100mΩ at 100 kHz
C3
100nF multilayer ceramic capacitor, general purpose
R1
450Ω resistor, carbon film, ±1% tolerance
R2
50Ω BNC termination
T1
3T of the coax cable through a ferrite toroid
RLOAD
Resistive load to the maximum power rating of the DC-DC converter. Connections should be made via twisted wires
Measured values are multiplied by 10 to obtain the specified values.

RoHS COMPLIANCE, MSL AND PSL INFORMATION
This series is compatible with Pb-Free soldering systems and is also backward compatible with Sn/Pb soldering systems.
The MGJ6 full bridge series has a process, moisture, and reflow sensitivity classification of MSL2 PSL R7F as defined in
J-STD-020 and J-STD-075. This translates to: MSL2 = 1 year floor life, PSL R7F = Peak reflow temperature 245°C with a
limitation on the time above liquidus (217°C) which for this series is 90sec max. The pin termination finish on this product
series is Gold with Nickel Pre-plate.
