Q67040-S4469

The Q67040-S4469 is designed as one kind of fast switching EmCon diodes.

Q67040-S4469 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-S4469 have been concluded into several points as follow. (1)Its repetitive peak reverse voltage would be 600V. (2)Its continuous forward current would be 71A at Tc=25°C and would be 47A at Tc=90°C. (3)Its surge non-repetitive forward current would be 162A at Tc=25°C and tp=10ms sine halfwave. (4)Maximum repetitive forward current would be 111.5A at Tc=25°C and tp limited by Tjmax, D=0.5. (5)Its power dissipation would be 187W at Tc=25°C and would be 106W at Tc=90°C. (6)Its operating and storage temperature range would be from -55°C to 175°C. (7)Its soldering temperature 1.6mm (0.063 inch) from case for 10s would be 255°C. (8)Its thermal resistance junction to case would be max 0.8K/W. (9)Its thermal resistance junction to ambient leaded would be max 62K/W. (10)Its SMD version, device on PCB would be max 62K/W at mion footprint and would be typ 35K/W at 6cm2 cooling area. 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-S4469 are concluded as follow. (1)Its reverse leakage current would be max 50uA at Vr=600V and Tj=25°C and would be max 3000uA at Vr=600V and Tj=150°C. (2)Its forward voltage drop would be typ 1.5V and max 2.0V at If=45A and Tj=25°C and would be typ 1.5V at If=45A and Tj=150°C. (3)Its peak reverse current would be typ 23A at Vr=400V and If=45A and Tj=25°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.
