MURS340S

The MURS340S 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 and telecommunication.

MURS340S has seven features. (1)Glass passivated chip junction. (2)Ideal for automated placement. (3)Ultrafast reverse recovery time. (4)Low switching losses, high efficiency. (5)Meets MSL level 1, per J-STD-020, LF maximum peak of 260°C. (6)Solder dip 260°C, 40s. (7)Compliant to RoHS directive 2002/95/EC and in accordance to WEEE 2002/96/EC. Those are all the main features.

Some absolute maximum ratings about MURS340S have been concluded into several points as follow. (1)Its maximum repetitive peak reverse voltage would be 400V. (2)Its maximum average forward rectified current would be 3.0A at Tm=130°C and would be 1.5A at Ta=25°C. (3)Its peak forward surge current 8.3ms single half sine-wave superimposed on rated load would be 35A. (4)Its operating junction and storage temperature range would be from -65°C to 175°C. It should be noted that stresses above those values listed in the absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of MURS340S are concluded into several points as follow. (1)Its maximum instantansous forward voltage would be 1.45V at Tj=25°C, If=3.0A and would be 1.2V at Tj=150°C, If=3.0A. (2)Its maximum instantansous reverse current would be 5.0uA at Tj=25°C and would be 150uA at Tj=150°C. (3)Its maximum reverse recovery time would be 50ns with current would be If=0.5A, Ir=1.0A, Irr=0.25A. (4)Its typical thermal resistance would be 120°C/W for junction to ambient. (5)Its case would be DO-214AA (SMB) epoxy meets UL 94 V-0 flammability rating. (6)Its polarity is color band denotes cathode end. (7)Its terminals would means matte tin plated leads, solderable per J-STD-002 and JESD 22-B102. And so on.
