3EZ15D5RLG

Single Zener Diodes Overview

The onsemi 3EZ15D5RLG is a silicon-oxide passivated Zener diode in the 3EZ4.3D5 series, rated for 3 watts of steady-state power dissipation at 75°C lead temperature. It features a nominal Zener voltage of 15 V with a ±5% tolerance range (14.25 V to 15.75 V) measured at a test current of 50 mA. The device utilizes an axial-lead DO-41 plastic package and offers high surge capability, including a 98 W rating at 1 ms duration. It provides excellent operating characteristics suitable for various environmental conditions.

Single Zener Diodes Feature Summary

• Utilizes silicon-oxide passivated junctions for superior electrical stability and reliability.
• Features a robust 3-watt power dissipation rating within a compact axial-lead package.
• Includes high electrostatic discharge protection exceeding 16 kV per the Human Body Model.
• Guarantees maximum limits across multiple key electrical parameters for design consistency.

Single Zener Diodes Applications

• Voltage regulation in electronic circuits requiring stable reference levels.
• Protection against overvoltage transients and surges in sensitive components.
• Clamping applications in power supply designs to limit peak voltages.

Single Zener Diodes Procurement Notes

Verify that the specific part number suffix matches the required reel quantity and orientation. Confirm RoHS compliance status as specifications apply to both standard and Pb-free devices. Ensure the ordering code aligns with the desired tape and reel packaging configuration rather than bulk box quantities.

Single Zener Diodes Selection Notes

Select this component when a 15 V regulation point is required with a 3-watt thermal capacity. Consider the ±5% voltage tolerance and the specific test current of 50 mA for circuit calculations. Evaluate the thermal derating requirements based on the expected ambient temperature and lead length to ensure operation remains within the specified junction temperature limits.

Single Zener Diodes Part Context

This device belongs to the 3EZ4.3D5 series manufactured by Semiconductor Components Industries, LLC (onsemi). The series covers a wide Zener voltage range from 4.3 V to 330 V, all housed in the same DO-41 Surmetic 30 case. The RLG suffix indicates a specific tape and reel packaging option for automated assembly processes.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 3EZ15D5 variants from different manufacturers or the standard bulk version 3EZ15D5/D if reel packaging is not required. Verify that any replacement maintains the 3-watt power rating and DO-41 footprint compatibility.
