Single Zener Diodes Procurement Notes

Verify that the specific part number matches the required military qualification level (JAN, JANTX, JANTXV, or JANS) as commercial versions may differ in specifications. Confirm RoHS compliance status if environmental regulations apply, noting that RoHS options are typically available only on commercial grades. Ensure the ordering suffix aligns with the desired lead finish and packaging format before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component when a 12 V reference is needed with a positive temperature coefficient suitable for higher voltage applications. The DO-35 package supports through-hole mounting, while surface mount alternatives exist in the same series. Consider the power derating requirements above 50 °C to ensure the 500 mW rating remains sufficient for the operating environment.

Single Zener Diodes Part Context

This device belongs to the 1N4099-1 through 1N4135-1 series of 500 mW Zener diodes manufactured by Microchip Technology. These components are JEDEC registered and qualified per MIL-PRF-19500/435. The series offers voltages from 1.8 to 100 V with various tolerance options, providing a standardized solution for precision regulation tasks in demanding environments.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same family include the 1N4105-1 and 1N4107-1, which share identical package dimensions and power ratings. Verify that any replacement maintains the required 12 V nominal voltage and acceptable tolerance levels for the specific circuit application.

Single Zener Diodes FAQ

What is the polarity orientation for the 1N4106-1?

The cathode is indicated by a band on the glass body. For Zener regulation, the banded end must be connected positive with respect to the opposite end.

How does the temperature coefficient affect the 1N4106-1?

The 1N4106-1 has a positive temperature coefficient of +0.08 %/°C, meaning the Zener voltage increases slightly as the junction temperature rises above 25 °C.
