Reflow and Pin-in-Paste Compatibility for VNP Series TO-220

Jay7 · ‎2026-03-13

Hi,

We are currently using the parts listed below and would like to confirm if they are reflow compatible. We plan to use a paste-in-hole (pin-in-paste) process for these through-hole components during SMT assembly.

Could you please advise if the following parts can withstand this process:

1) VNP35N07-E

2) VNP49N04-E

3) VNP35NV04-E

Thank you

Jay Trivedi

Thank you very much for your interest; however, you have simultaneously asked the same question with a ticket numbered 00256729 through the personal Online Support OLS. It is not really productive to bombard all possible support channels at once, so let's wait and see what the colleagues from OLS have to say about it.

One thing in advance: the second OMNIFET VNP49N04-E is already obsolete and is no longer being manufactured.

For pin-in-paste (paste-in-hole) SMT assembly, it’s important to verify that the components are reflow compatible and can withstand the temperatures of the soldering process. Generally, many modern through-hole MOSFETs like VNP35N07-E, VNP49N04-E, and VNP35NV04-E are designed to tolerate standard reflow profiles, but it’s always best to check the datasheet for the maximum soldering temperature and recommended reflow profile.

If the datasheet doesn’t explicitly mention pin-in-paste or reflow compatibility, you might also want to contact the manufacturer or supplier to confirm before assembly.

This is a kind reminder regarding our earlier request for confirmation on the reflow compatibility of the mentioned component.

We would also appreciate your guidance on the recommended reflow temperature profile.

Thanks,

Jay

You would need to place the reminder at the OLS in your ticket 00256729, as the community is largely independent of it.

Thank you very much for your understanding.

Hi Peter ,

I have already placed the reminder in the OLS for ticket 00256729, but I have not received any response yet.

Could you please check and advise on the next steps or escalate this further?

Thank you,

Jay

Unfortunately, I have no way to expedite anything in the OLS team and can only ask for some patience. The Easter holidays probably caused delays.
