SMD Diodes for H bridge motor driver -- BAS40-04LT1GOSCT-ND

Not being a engineer, but having some knowledge of electronics, I would say that you do not want to exceed these specifications. Generally, you want things like capacitors, to have a 250% over supply voltage rating when it comes to voltage specification. I am not sure if that applies to diodes on not.

Current - Peak Output	1.5A
Voltage - Supply	3.8 V ~ 13.2 V
