RT5047 current limiter board diode substitution question

Post by Basil » Sun Jun 13, 2021 9:42 am

Can I use these diodes from RS as substitutes for D11-13,15 D21-23,25 SOD-123F SS14 DigiKey part number 1655-1927-1-ND ???


RS Link: https://uk.rs-online.com/web/p/schottky ... s/0508933/

DigiKey have no stock of 1655-1927-1-ND

The schematic of the LNB current limiters seems to show them as Zener diodes, yet DigiKey show them as Schottky diodes...

Its' just a generic SS14 Schottky so an equivalent ought to be fine.

Thank you Mike, I have just ordered them from RS, having current limiting seems a good idea, especially whilst I am still messing with the set ups.
