TVS1400: protecting SN65HVD230D

Part Number: TVS1400
Other Parts Discussed in Thread: SN65HVD230

Hello,

Would the TVS1400 protection device be a good fit to protect a SN65HVD230D working at 1Mbaud ?

Breakdown and clamping voltages seem to be adequate.

I need the SN65HVD230 protected up to at least ±15kV following IEC 61000-4-2.

Thank you.

Regards,

Victor Tolosana

    Hi Victor,

    I would not recommend TVS1400 for this application. It is mainly a surge protection device and not meant for data signals with fast rise times. It has a a slew rate limitation in which if the slew rate increases past 2.5 V/us, the device will start leaking a significant amount of current. 

    Unfortunately we currently do not have any ESD devices for CAN. However, we are in the process of developing one.

    Hello Matt,

    Thank you for the detailed explanation.

    Do you have another TVS device capable of protecting the SN65HVD230 lines @1Mbaud ? 

    Even if it is not made for CAN and/or we have to use one on each CAN signal.

    Thank you very much.

    Regards,

    Hello Victor,

    Unfortunately we do not. SN65HVD230's CANH and CANL lines can be subject to bus faults up to 16 V, which we do not have a part for at this time.
