Single Zener Diodes Procurement Notes

Verify that the ordering suffix 'TR' corresponds to tape-and-reel packaging and 'PBFREE' indicates lead-free plating as specified by the manufacturer. Confirm compliance with RoHS directives and check for any specific environmental or export control classifications required for your region before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a precise 11 V reference is required in a standard axial glass package. Ensure the application current does not exceed the 20 mA test current threshold to maintain accurate voltage regulation. Verify that the 500 mW power dissipation limit accommodates the expected thermal environment without exceeding the maximum junction temperature.

Single Zener Diodes FAQ

What marking code identifies this specific diode?

The device is marked with the prefix 'C' followed by the full part number, or alternatively by the marking code C5241B.

How does the temperature coefficient affect performance?

The diode has a positive temperature coefficient of +0.076 %/°C, meaning the Zener voltage increases slightly as the temperature rises above room temperature.
