Single Zener Diodes Procurement Notes

Verify the specific suffix 'e3' confirms RoHS compliance and lead-free status as per manufacturer specifications. Confirm package type matches DO-35 requirements for your PCB layout. Check current availability status directly with authorized distributors, as supply levels for legacy or specific suffix variants may fluctuate. Ensure ordering documentation explicitly references the full part number to avoid confusion with non-compliant or different tolerance variants.

Single Zener Diodes Selection Notes

Select this component when a 2.4 V reference is required in a through-hole configuration. The DO-35 package suits automated insertion processes. Consider the 500 mW power rating against expected circuit dissipation. Verify that the ±5% tolerance meets system accuracy needs. Compare against other series members if higher voltages or tighter tolerances are necessary for the design.

Single Zener Diodes Part Context

This device belongs to the 1N4370 series of 0.5 W Zener diodes produced by Microchip Technology. The series offers a range of voltages from 2.4 V to 12 V. The 'e3' suffix denotes environmental compliance, specifically lead-free construction. These diodes are widely used in general-purpose electronics where reliable voltage regulation is critical.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 1N4370A variants with compatible electrical characteristics. Cross-reference with equivalent parts from other manufacturers ensuring identical voltage, power, and package specifications. Verify that any replacement maintains the same temperature rating and impedance profile.
