Single Zener Diodes Procurement Notes

Verify the specific suffix (e.g., E3) to confirm lead-free compliance and packaging type (tape and reel vs. tube). Ensure the DO-41 through-hole footprint matches the PCB layout requirements. Cross-reference the manufacturer's latest datasheet for any updates on thermal derating curves or storage conditions before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 15 V reference with 1.5 W power handling is required in a standard axial leaded package. Consider the 9 Ohm impedance limit for dynamic regulation needs. Verify that the ±5% tolerance aligns with circuit precision requirements. Ensure compatibility with existing JEDEC standards if replacing legacy parts in established designs.

Single Zener Diodes Part Context

This component belongs to Microchip's single Zener diode portfolio, specifically within the JEDEC registered series. It utilizes a void-less hermetically sealed glass package with triple-layer passivation, offering robust construction suitable for demanding environments. The DO-41 form factor provides reliable through-hole mounting capabilities for general-purpose electronics.

Single Zener Diodes Replacement Considerations

Direct substitutes must match the 15 V Zener voltage, 1.5 W power rating, and DO-41 package. Verify equivalent impedance and tolerance specifications. Check for identical pinout and hermetic sealing requirements to ensure functional parity in existing assemblies.
