Part Number: DCV010505
Other Parts Discussed in Thread: DCP010505B

Dear TI,

There are two questions below.
1. DCV010505 Vs DCP010505B
 => Are there any differences except for the operating temperature range?
2. Isolation
 => What is the isolation between the devices?
 => If you have a document such as a certification document, can you share it?

    Hi ,

    Looking at both these devices, the difference are as follows:

    1. DCP010505B has a lower maximum input voltage range 
    2. DCP010505B has a higher maximum operating ambient temperature(100C) compared to the DCV010505(85C)
    3. DCV0105 is 1.5kVrms isolation compared to 1kV of the DCV010505.

    Is there any feature particular that you are looking for?

    Regards,

    Jimmy

    Dear Jimmy,
    Thank you for your attention and support.
    The features I'm looking for are:
    -> Products with an insulation distance of more than 3.4mm between primary and secondary.
    Is there documentation of insulation distances for these two products?

    Hi BJ,

    I had a talk with the design team and they stated that these devices are recommended  for SELV(60VDC) ratings and is advised not to use as an element of safety isolation system if SELV is exceeded. Through time and usage, the insulation distance will decrease until the device can only be guaranteed for SELV. As such there is that very recommendation is mentioned in Section 8.3.1.3 in the datasheet. Do note that the DCV01 products do not provide basic or enhanced isolation (insulation distance) that is defined by specified creepage and clearance limits between primary and secondary circuit. 

    Regards,

    Jimmy
