GSQ05A04B

The GSQ05A04B is designed as one king of SBD by the nihon inter electronics corporation.

GSQ05A04B has five features. (1)Similar to TO-220AC case. (2)Low forward voltage drop. (3)Low power loss and high efficiency. (4)High surge capability. (5)Tj=150°C operation. Those are all the main features.

Some absolute maximum ratings of GSQ05A04B have been concluded into several points as follow. (1)Its repetitive peak reverse voltage would be 40V. (2)Its average rectified output current would be 5A at Tc=122°C 50Hz half sine wave resistive load. (3)Its RMS forward current would be 7.85A. (4)Its surge forward current would be 120A at 50Hz half sine wave, 1cycle non-repetitive. (5)Its operating junction temperature range would be from -40°C to +150°C. (6)Its storage temperature range would be from -40°C to +150°C. (7)Its mounting torque would be recommended 0.5Nm. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of GSQ05A04B are concluded as follow. (1)Its peak reverse current would have the maximum value of 5mA with test conditions of Tj=125°C and Vrm=Vrrm. (2)Its peak forward voltage would have the maximum value of 0.55V with test conditions of Tj=25°C and Ifm=5A. (3)Its thermal resistance would have the maximum value of 5°C/W from junction to case. (4)At Tj=25°C its instantaneous forward current vs instantaneous forward voltage would be min 0.5A at 0.4V and would be max 20A at 1.0V. (5)At Tj=150°C its instantaneous forward current vs instantaneous forward voltage would be min 0.5A at 0.22V and would be max 20A at 0.82V. (6)Its average forward power dissipation would be 4W at average forward current of 7A. Those are all the main electrical and thermal characteristics.

At present we have not got so much information about GSQ05A04B and we would try hard to get more information. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
