Part Number: ISO7841 Other Parts Discussed in Thread: ISO7341C Hi all,
I would like to know the carrier frequency used in ISO7841 and similar digital isolators. This relates to some issues we encounter with close proximity GSM antenna transmissions…
Hi Tim,
Following are the responses:
1. Regarding IEC61010-1:
You are correct, IEC 61010-1 is a system-level standard and typically end-equipment is certified to this standard. Isolation components, like ISO7841, are only certified to specific…

We are using the ISO7841DWW part to isolate an ADC which is continuously measuring 240V mains voltage. We have diagnosed some data corruption to the ISO7841 during transmission…
Hello,
Thank you for the question and your interest in the ISO78xx series of isolators. The external clearnace and creepage of the ISO7841 is limited by the package of the device and the layout of the board. So for the DW package, the minimum creepage…
Part Number: ISO7841 Hi,
I have a ESD diode at the power supply of IC ISO7841DWR. I need to confirm to what clamp voltage this IC can handle. The maximum allowable voltage per datasheet is 6V. But what if there is a peak at nano-seconds due to ESD…
Part Number: ISO7841 Other Parts Discussed in Thread: ISOW7841 ,
I see the V_IOWM rating for the ISOW7841 (3/1 data + integrated power) and ISO7841 (3/1 data, no power) is very different:
ISOW7841 DWE (>8mm clearance/creepage):
1000V RMS or …
Part Number: ISO7841 Hello,
We would like to know how ISO7841 and ISO7220 protects from ESD. I think the below is a general ESD protection. Can we think similar structure which input/output pins have diodes, ground-to-signal, signal-to-vcc?
Best…
Part Number: ISO7841 Hi,
my previous thread with the same question seems to be deleted, why is that?
And my question is:
Is it possible to increase the test voltage of the ISO7841 to 5760 Vrms? The test will be according to EN 61010-1, 1 min a…

Hi!
I see that the TI ISO7841 is UL 1577 certified for a test voltage of 5700 Vrms, we have a system with the following requirements:
Isolation voltage: >= 5760 Vrms
Working voltage…
