MURS340

The MURS340 is designed as one kind of surface mount ultrafast plastic rectifiers for use in high frequency rectification and freewheeling application in switching mode converters and inverters for consumer, computer, automotive and telecommunication.

MURS340 has eight features. (1)Glass passivated chip junction. (2)Ideal for automated placement. (3)Ultrafast reverse recovery time. (4)Low switching losses, high efficiency. (5)High forward surge capability. (6)Meets MSL level 1, per J-STD-020, LF maximum peak of 260°C. (7)Solder dip 260°C, 40s. (8)Component in accordance to RoHS 2002/95/EC and WEEE 2002/96/EC. Those are all the main features.

Some absolute maximum ratings about MURS340 have been concluded into several points as follow. (1)Its maximum repetitive peak reverse vvoltage would be 400V. (2)Its working peak reverse voltage would be 400V. (3)Its maximum DC blocking voltage would be 400V. (4)Its maximum average forward rectified current would be 3.0A at Tl=130°C and would be 4.0A at Tl=115°C. (5)Its peak forward surge current 8.3 ms single half sine-wave superimposed on rated load would be 125A. (6)Its operating junction and storage temperature range would be from -65°C to 175°C. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of MURS340 are concluded as follow. (1)maximum instantaneous forward voltage would be 1.25V at If=3.0A, Tj=25°C and would be 1.28V at If=4.0A, Tj=25°C and would be 1.05V at If=3.0A, Tj=150°C. (2)Its maximum instantaneous reverse current at rated DC blocking voltage would be 10uA at Tj=25°C and would be 250uA at Tj=150°C. (3)Its maximum reverse recovery time would be 50ns with conditions of If=0.5A, Ir=1.0A, Irr=0.25A. (4)Its maximum forward recovery time would be 25ns. And so on. At present we have not got so much information about this MURS340 and we would try hard to get more information about it.
