TI isolated power chip production date problem [Copy link]

 

Can you tell me if I can get the production date of the chip from the batch number of the power supply? For example, the batch number of the dcp020505u I bought is 04zdk1h. Can I determine the approximate production date? What does each letter of the batch number mean? Can someone who knows please guide me? Thank you very much.

04zdk1h This one doesn't seem to show the production date

If the official does not announce the meaning of these characters, it may involve the company's internal production process.

Generally, you can find the corresponding FAE of the original factory, or the sales can get the corresponding laser mark manual, which has an introduction. The batch number may correspond to 04zdk year, month, week

Ask TI's technical support. The dcp020505u is packaged in a plastic tube, or you can check the label on the plastic tube to see if there is a production date.
