Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact testing criteria and screening levels. Confirm RoHS compliance status and packaging type directly with the supplier or manufacturer before procurement. Ensure the component meets all required environmental and electrical specifications for the intended application environment.
Selection Notes
Select this component for designs requiring a standard 30 V reference point with high thermal stability. The DO-41 package facilitates easy integration into through-hole PCB layouts. Consider the 1 W power rating and wide temperature range when evaluating thermal management requirements for the final assembly.
Part Context
This part belongs to the widely recognized 1N47xx series of 1-watt Zener diodes. The series offers extensive voltage selection from 3.3 V to 100 V. The 'A' suffix typically denotes a tighter voltage tolerance compared to standard variants. This specific model represents a standard commercial grade version manufactured by onsemi.
