Single Zener Diodes Procurement Notes

Verify the specific suffix HE3-08 against the datasheet to confirm lead-free status and tape-and-reel packaging configuration. Ensure the ordering part number matches the required tolerance and power rating specifications for your design. Cross-reference the manufacturer's latest documentation for any potential product change notices affecting this specific variant.

Single Zener Diodes Selection Notes

Select this component when a 15 V Zener voltage with ±5% tolerance is required in an SOD-123 footprint. Consider the 500 mW power rating and -55°C to +150°C operating temperature range for environmental compatibility. Verify that the surface-mount installation type aligns with your PCB assembly capabilities and that the leakage characteristics meet circuit requirements.

Single Zener Diodes Part Context

This component belongs to the MMSZ4702 series of single Zener diodes from Vishay. It is part of a broader family of silicon planar Zener diodes available in various voltage ratings and packages. The HE3 suffix indicates a specific manufacturing process or compliance standard, while the -08 suffix typically denotes the tape-and-reel packaging format for automated assembly.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 15 V, 500 mW Zener diodes in the SOD-123 package with ±5% tolerance. Verify pinout compatibility and thermal characteristics before substitution. Alternative manufacturers may offer equivalent parts, but electrical parameters must be matched precisely.
