Hi,

Planning to use TVS1400 on 12V DC line and TVS0500 on 6.2V DC Line. Since on TVS0500 VRWM is 5V, but the Clamping voltage is 9.2V and the Vbr is around 7.7V Are my part selection OK

Hi Sudarshan,

TVS0500 will not work as intended on a 6.2V DC line. We recommend that the DC voltage should be either equal or less than the working voltage to avoid any conduction, unnecessary clamping or leakage. You will have to step up the device used to TVS1400.

Hi, I am reopening this as i have few more queries w.r.t this device

1. From the below graphs over and above 7V only the clamping is happening for this device. Since our rail is at 6.2V this device should still holds good. Please let us know your feedback
