- Temperature-compensated reference designs
Procurement Notes
Verify the specific suffix configuration against official datasheets to confirm RoHS compliance and packaging type. Ensure the ordering code matches the required tolerance and thermal characteristics. Confirm availability status directly with the manufacturer or authorized distributors prior to finalizing procurement plans.
Selection Notes
Select this component for applications requiring robust 5W power handling and wide temperature stability. Consider the T-18 package dimensions and thermal resistance values when designing heat sinking solutions. Verify that the 20V breakdown voltage aligns precisely with the circuit's regulatory requirements.
Part Context
This device belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options. The e3 suffix indicates lead-free construction, while TR12 denotes the tape and reel packaging format.
Replacement Considerations
Consult the official datasheet for equivalent part numbers within the same series or cross-reference with other manufacturers offering compatible 5W Zener diodes with matching voltage and tolerance specifications.
