Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required lead-free or tin/lead terminal finish, as this affects RoHS compliance status. Confirm the package type is DO-41 and the voltage rating is 5.6 V. Ensure the manufacturer is identified as Central Semiconductor Corp to guarantee component authenticity and datasheet alignment.

Single Zener Diodes Selection Notes

Select this component when a 5.6 V Zener reference with 1 W power handling is required in an axial package. Consider the 20 Ω impedance and 5 µA leakage for precision requirements. Verify compatibility with the target PCB layout for DO-41 mounting and ensure the operating environment stays within the specified thermal limits.

Single Zener Diodes Part Context

This part belongs to the 1N47 series of silicon Zener diodes manufactured by Central Semiconductor. The series covers a wide voltage range from 3.3 V to 100 V with consistent 1 W power ratings. These components are widely used in general-purpose electronics for overvoltage protection and stable voltage referencing.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers' 1N4734A parts for pin-compatible substitution. Verify that alternative sources offer identical 5.6 V Zener voltage, 1 W power rating, and DO-41 package dimensions to maintain circuit integrity.
