Monster Moto amp board Zener diode Spec

This board being discontinued has led me down the road of reworking it for a project I am working on at the moment.

Working from the original design files, I have been able to nail down all the components except for the Zener diode on the S legs of the MOSFETs.

Does anybody know what the spec of this part is?

On an old unit I have I can see the marking “W4” on the package.

If you are talking about https://www.sparkfun.com/products/retired/10182 , the schematic can be found at http://cdn.sparkfun.com/datasheets/Dev/ … ld-v12.pdf

D1 is a BZT52 ; the data sheet can be found at https://www.vishay.com/docs/85760/bzt52.pdf. According to the datasheet, W4 is a 3.3V zener with a full part number of BZT52C3V3, and Digikey currently has them in stock.

Hi Mike, thanks for the help. Exactly what I needed. Will know what I’m looking for next time

Hello,

I’m working on a project with these monsters and I need more, what can I use in replacement as they are retired ?

Thanks
