MR4720

Pass Word

The MR4000/5000 Series incorporate the following main features

Use of second-generation high-speed IGBTs and CoolMOS devices

improves efficiency

Reduction of control IC loss improves standby characteristic

Same control functions as predecessor MR2000 Series, enabling

simple device design

Higher efficiency, low noise

The high-speed IGBTs developed by Shindengen are elements with

an original patented structure

The first-generation high-speed IGBT was released in the MR2000

Series. The second-generation high-speed IGBT altered the internal

structure of the first-generation model, improving on its saturation

characteristic and tail loss tradeoff characterisic. These improvements

further reduced the tail loss of the second-generation high-speed IGBT while maintaining the same saturation characteristic as the first-

generation model

Figure 2 compares the tail loss waveform of the first-and second-

generation high-speed IGBTs. After subtracting a 10 uJ loss

(corresponding to the juntion capacitance), the tail is reduced by

roughly half, from 77 to 39 uJ

( 1) Higher output capacity with FTO package

(Po for MR4040 [ FTO-7P ] = up to 180 W)

( 2 ) FTO package 7-pin configuration allows for distance between high-voltage pins

( 3 ) Use of second-generation high-speed IGBT with 900 V withstand voltage improves efficiency

( 4 ) Supports standby mode (pin at no load is about 60 mW)

Applications
