Single Zener Diodes Procurement Notes

Verify the specific suffix requirements for your application. The base part number indicates a commercial grade device. If RoHS compliance is required, confirm the availability of the e3 suffix variant. Ensure the metallurgical bond option (-1) matches your environmental specifications. Consult official documentation for screening options referencing MIL-PRF-19500 if higher reliability levels are needed.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed, axial-leaded Zener diode is required for high-reliability applications. The 1N4697-1 offers a 10 V breakdown voltage suitable for precise reference circuits. Consider the tight voltage tolerances available via specific ordering suffixes if stricter regulation accuracy is necessary compared to standard commercial equivalents.

Single Zener Diodes Part Context
