ESDS314: Device power rating for longer duration pulse

FS1
Prodigy 50 points
Part Number: ESDS314

1. Is the 170W power rating for the device or per channel?

2. Can you provide a power derating curve for varying pulse duration? I am particularly looking for the power rating at 120us. The datasheet only provides the power rating for 8/20us.

    Hi,

    Welcome to E2E!

    All parameters listed in the datasheet for the ESDS314 apply to each channel, so the 170W power rating would apply per channel per the IEC 61000-4-5 surge standard.

    The power rating of the ESD device was acquired by testing the device per the IEC 61000-4-5 surge standard. The data available for the ESDS314 is what is included in the datasheet. A surge pulse of 120us is much longer than the pulse the ESDS314 is tested against for which we can't guarantee the device will offer enough protection for your ESD/Surge/Fault condition.

    To learn more about the test for our protection devices refer to this application note: IEC 61000-4-xTests for TI’s Protection Devices

    Let me know if you have any questions.

    Best regards,

    Andy Robles
