Single Zener Diodes Procurement Notes

Verify that the ordering code explicitly contains the 'B' suffix to confirm the required ±5% tolerance specification. Ensure the '-TR' suffix matches the intended taped-and-reeled packaging format for automated assembly processes. Cross-reference the document number 85588 for the most current electrical characteristics and absolute maximum ratings.

Single Zener Diodes Selection Notes

Select this component when a 4.7 V reference point is required with moderate precision. The DO-35 package supports through-hole mounting and offers high thermal stability up to 175 °C. Consider the specific test current requirements for the application against the datasheet specifications.

Single Zener Diodes Part Context

This part belongs to the 1N5221 to 1N5267 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.4 V to 75 V, providing standardized options for various discrete semiconductor voltage regulation needs.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other manufacturers' 1N5230B equivalents or Vishay's own variants such as the 1N5230B-TAP (Ammo Pack) and 1N5230B-series-TR, provided they maintain identical voltage, power, and package specifications.
