Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against the manufacturer datasheet to confirm RoHS compliance status and tolerance grade. Confirm that the TR suffix indicates tape and reel packaging per EIA-481-B standards. Ensure the ordering part number matches the required voltage tolerance and screening level for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when a hermetically sealed surface mount Zener diode is required as a direct replacement for axial leaded equivalents. Consider the 17 V breakdown voltage and 0.5 W power dissipation limits. Evaluate the high dynamic impedance and positive temperature coefficient for circuit stability requirements within the specified operating temperature range.

Single Zener Diodes Part Context

This device belongs to the 1N5221BUR-1 through 1N5281BUR-1 series of metallurgically bonded glass surface mount Zeners. These components serve as surface mount equivalents to the popular JEDEC registered 1N5221 to 1N5281 series, offering voltages from 2.4 to 200 volts in a compact DO-213AA package.

Single Zener Diodes Replacement Considerations

Direct surface mount replacements for axial 1N5247B devices are available within the same series. Verify pinout polarity and thermal resistance characteristics when transitioning from through-hole to surface mount implementations.
