Original question:

TPD6E001: Dynamic Resistance of TPD6E001

TPD6E001: Vc, clamp voltage TYPICAL values for this part with a different pulse definition

Part Number: TPD6E001
Other Parts Discussed in Thread: TPD6E05U06, , STRIKE

Hello,

We are currently using the TPD6E001 in our application.  On the data sheet, the Vc channel clamp voltage is rated as a MAX value for various transients defined by the HBM and IEC standards.  On your newer series parts, like the TPD6E05U06, the clamp voltage, Vclamp, uses a much different pulse (100 ns with 200 ps rise time), and shows TYPICAL values from 3V to 14V depending upon direction and current levels of the pulse.  Our question: Is the TYPICAL Vc for the TPD6E001 for similar pulse definitions about the same as the TPD6E05U06?  If not, what are the TYPICAL clamp voltage values for this part?

Thanks

    Hi Mike, 

    Thank you for reaching out. The typical Vclamp for TPD6E001 for an 8 kV IEC strike should be around 15 V if you look at figure 4 in the data sheet. The max value was most likely taken at high temperature, no Vcc connection, and no coupling capacitor. You can compare this to figure 6 of TPD6E05U06 and see it is about 23 V Vclamp. For future reference, an 8 kV IEC strike is equivalent to a 16 A TLP (figure 3)

    Regards,

    Matt,

    Thanks for the details and the explanation of the clamp voltage response.
