Hi Chen,

The TVS1400 is rated for 60 W for a 10/1000 us waveform when it is forward biased (GND to IN). It is rated for 140 W when it is reversed biased (IN to GND). TV04WF doesn't specify whether the rating is forward or reversed, but I would assume reversed since that is normal operation for the device.

Please let me know if you need any clarification.

Regards,

Matt Smith

Hi Chen,

Yes, it looks like TV04WF has a better 10/1000us power rating than TVS1400. TVS1400 is the best 14 V part we currently have in our portfolio. One thing to note is that TVS1400 has a much better clamping voltage at Ipp than TV04WF. TVS1400 is ~18 V where TV04WF is ~23 V. Therefore, your system will receive less voltage during a surge event with TVS1400 than with TV04WF. Just something to consider.
