SN55HVD233-SP: Seeking additional SEE (Single Event Effects) radiation data - SEL/SEU (MeV/mg/cm^2) ratings

Mathew Dinh

Part Number: SN55HVD233-SP
Other Parts Discussed in Thread: OPA4277-SP

Tool/software:

Hello,

I am currently evaluating the SN55HVD233-SP (5962L1420901VXC) for a space application that requires high reliability in a radiation-exposed environment. While the datasheet provides detailed information on the total ionizing dose (TID) tolerance, I could not locate specific data regarding the device’s susceptibility to Single-Event Effects (SEE), particularly Single-Event Latchup (SEL) and Single-Event Upset (SEU).

I would appreciate any additional information or education on the topic in either radiation characteristics or SEE immunity by design if appropriate.

Thank you!

Hi Mathew,

We have some documents on the product page for the device. Have you taken a look at those documents yet? (It's in the technical documentation section if you scroll down on the product page). I've screenshot the section below.

Hi Bobby,

I apologize for the delayed response. I have looked at those documents and I maybe I missed it, but I am seeking some info similar to the image shown below (of the OPA4277-SP) SEL conditions. I am trying to see if there is a SEL-immune rating as well as an SEU rating for the SN55HVD233-SP either through testing or by design. If by design, I am trying to see if I can receive some verbiage from a TI expert to help build our analysis.

Regards,

Mat

Mat,

Our manager has pointed us to this document: https://www.ti.com/lit/rr/slla381/slla381.pdf?ts=1733180932519&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FSN55HVD233-SP

Is the information you're looking for not included in it?
