Other Parts Discussed in Thread: TPD1E01B04, TPD1E1B04
Hi team,
Can TPS1E0B04 be used for antenna like LTE? The customer wants to use it as alternative part of LXES15AAA1-133.

Hi Takeshi,
Welcome to E2E!
From what I can see the part they are using right now (LXES15AAA1-133) has a working voltage range of up to 15V and a very low capacitance. The TPD1E0B04 only has a working voltage range of up to 3.6V and a capacitance of 0.15 typical in the P2P package. In order to verify if this can be used in the application I would need more information:

Hi Andy,
Thank you for your comment.
Q1. What will be the working voltage of the lines being protected?
A1. 3.3V. The LTE line will be estimated about 3.16V.
Q2. What is the data speed in the signal lines?
A2. The fastest line is 2.1GHz. The other lines are up to several 10 MHz, so the customer considers TPD1E10B09DPYR has enough spec.
Can TPD1E0B04 be used for the above application?
Best regards,

Hi Takeshi,
Because of the working voltage range being 3.3V and with the given data speeds there are a couple a devices that could be positioned here. The TPD1E0B04 would be one of them as well as the TPD1E01B04, and TPD1E1B04. The biggest difference between all of these devices would be the capacitance, and the level of ESD protection they offer. Do you think any of these devices would interest the customer?
I do have a question for the customer. The original device they were using has a working voltage of up to 15V. Is there a reason they choose that specific device for this socket? Will there be any high voltages present for long periods of time?
The above questions are due to our devices being able to get damaged with DC voltages applied that are greater than the breakdown voltage of our devices. If there's the chance of having a high voltage during a fault event the ESD device could get damaged.
