UCC21520: Could you tell me about UCC21520?

Pokkun

Part Number: UCC21520

Hi team.

I tried to sell UCC21520 for driving the IGBT mounted on the train VVVF.

Please tell me about the question about UCC21520 that time.


· Although there is the following description in the data sheet, is this OK with recognition with DC?



· What is the withstand voltage at AC?

Could you help me?

Best regards,
Masumi Sekiguchi.

Masumi, the internal IC spacing/design supports 1.5KVpk functional isolation from one channel to the other. In practice, the customer must consider the pin-to-pin spacing, PCB design rules, pollution degree and whether the PCB is coated or not to determine the maximum bus voltage.

Thank you for the answer, Peter-san.

I still do not know a little, so please tell me.

this is supporting 1.5 Vpk,Is it a little lower at DC level withstand voltage?
(do it tell me what volt it is, if it can tell.)

Best regards,
Masumi Sekiguchi.

You're welcome. The value is for steady-state or recurring peak.
