Single Zener Diodes Procurement Notes

Verify the specific ordering code suffix against the manufacturer's documentation to confirm packaging details. Ensure that the required tolerance aligns with the 'B' designation specifications. Confirm compliance requirements such as RoHS status prior to finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 8.7 V reference is required in an axial through-hole configuration. Consider the 600 Ω dynamic impedance and 500 mW power dissipation limits during circuit design. Evaluate thermal resistance characteristics if operating near maximum ambient temperature limits.

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 range of nominal voltages from 2.4 V to 75 V, offering standardized electrical characteristics and consistent physical dimensions across the product family.

Single Zener Diodes Replacement Considerations

Direct substitutes include other manufacturers' equivalents meeting the 1N5238 specification. Verify pinout compatibility and ensure the replacement device meets or exceeds the 500 mW power dissipation rating and 8.7 V nominal voltage requirement.
