Q67040-S4484

The Q67040-S4484 is designed as one kind of fast switching EmCon diode.

Q67040-S4484 has seven features. (1)600V EmCon technology. (2)Fast recovery. (3)Soft switching. (4)Low reverse recovery charge. (5)Low forward voltage. (6)Easy paralleling. (7)175°C operating temperature. Those are all the main features.

Some absolute maximum ratings of Q67040-S4484 have been concluded into several points as follow. (1)Its repetitive peak reverse voltage would be 600V. (2)Its continuous forward current would be 29.2A at Tc=25°C and would be 19.6A at Tc=90°C. (3)Its surge non-repetitive forward current would be 60A at Tc=25°C and tp=10ms sine halfwave. (4)Its maximum repetitive forward current would be 45A at Tc=25°C, tp limited by Tjmax and D=0.5. (5)Its power dissipation would be 83.3W at Tc=25°C. (6)Its operating and storage temperature range would be from -55°C to 175°C. (7)Its soldering temperature would be 255°C at 1.6mm (0.063 inch) from case for 10 seconds. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of Q67040-S4484 are concluded as follow. (1)Its reverse leakage current would be max 50uA at Vr=600V and Tj=25°C and it would be max 1250uA at Vr=600V and Tj=150°C. (2)Its forward voltage drop would be typ 1.5V and max 2V at If=15A and Tj=25°C and it would be typ 1.5V at If=15A and Tj=150°C. (3)Its peak reverse current would be typ 13.7A at Vr=400V, If=15A and Tj=25°C and it would be typ 16.4A at Vr=400V, If=15A and Tj=125°C. (4)Its reverse recovery siftness factor would be typ 3.6 at Vr=400V and If=15A and Tj=25°C and it would be typ 4.3 at Vr=400V, If=15A and Tj=125°C. And so on. At present we have not got so much information about this IC and we would try hard to get more information about it.
