AD5422 Protection Diode

Dear team:
Consult Figure 82 in the AD5422 data sheet. How the Schottky diodes D2 and D1 are selected (can you give a recommendation)? Operating voltage is 24V. Here's what D2 and D1 do.

  • Dear Rainier,

    Due to my lack of experience, a brief discussion of the transient voltage protection section on page 39 of the data sheet does not help me to correctly select Schottky diodes. Such as the Schottky diode protection voltage is 24V? Whether the reverse current and forward voltage need to be low, how little influence the 4-20mA output and so on. Please give instructions.

    Best regards,
