Single Zener Diodes Procurement Notes

Verify the component origin as the datasheet originates from the Microsemi Scottsdale Division. Confirm that the 'e3' suffix indicates RoHS compliance and the 'TR13' suffix denotes tape and reel packaging per EIA-296 standards. Ensure the specific part number matches the required 7.5 V rating and ±10% tolerance before procurement.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation capability is required for high-current applications. The axial lead configuration is suitable for designs needing robust mechanical mounting. Consider the thermal resistance specifications and derating curves if the ambient temperature exceeds 25°C or if heat sinking on FR4 PCBs is utilized.

Single Zener Diodes Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V.
