Single Zener Diodes Procurement Notes

Verify that the ordering suffix -TP corresponds to the Tape & Reel packaging format, which contains 4,000 pieces per reel. Confirm compliance requirements such as the -HF suffix if halogen-free material is required. Ensure the specific manufacturer datasheet revision matches the procurement specifications to avoid discrepancies in electrical characteristics or mechanical dimensions.

Single Zener Diodes Selection Notes

Select this component when a robust 5-watt axial Zener diode is needed for high-power regulation tasks. The DO-15 package offers superior thermal dissipation compared to smaller surface-mount alternatives. Consider the 1.5 Ohm dynamic impedance for stability requirements and verify that the 8.2V breakdown voltage aligns precisely with the circuit design parameters.

Single Zener Diodes Part Context

This part belongs to the 1N5338B through 1N5388B series manufactured by Micro Commercial Components. The series covers a wide voltage range from 5.1V to 200V, all sharing the same 5-watt power dissipation capability and DO-15 axial leaded package. The -TP suffix specifically denotes the standard tape and reel packaging configuration for automated assembly processes.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the onsemi 1N5344BRLG and the Microsemi 1N5344B. Verify that replacement parts maintain the identical 8.2V Zener voltage, 5W power rating, and DO-15 package footprint to ensure direct interchangeability without modifying the printed circuit board layout.
