Product Summary

The MR4020 is a partial power supply IC module with a function for switching to standby mode during micro loads. It is comprised of a switching element and control IC optimized to 100V class, 200V, and worldwide input power supplies.

Parametrics

MR4020 absolute maximum ratings: (1)DC Blocking Voltage, VR: 18Volts; (2)Average Forward Current (Single Phase, Resistive Load, TC = 185℃), IO: 40Amps; (3)Peak Repetitive Reverse Surge Current (Time Constant = 10 ms, TC = 25℃), IRSM: 110 Amps; (4)Peak Repetitive Reverse Surge Current (Time Constant = 80 ms, TC = 25℃), IRSM: 50 Amps; (5)NonRepetitive Peak Surge Current(Halfwave, Single Phase, 50 Hz), IFSM: 500 Amps; (6)Storage Temperature Range, Tstg: 40 to +200℃; (7)Maximum Operating Junction Temperature, TJ: 200℃.

Features

MR4020 features: (1)use of second generation high speed IGBTs and coolCMOS device improve efficiency; (2)reduction of control IC loss improves standby characteristic; (3)same control functions as predecessor MR2000 series; (4)higher efficiency, low noise.
