2EZ15D5E3/TR12

Single Zener Diodes Overview

The 2EZ15D5E3/TR12 is a silicon axial-leaded Zener diode from the Microsemi 2EZ series, housed in a DO-41 plastic package. It provides a nominal Zener voltage of 15 V with a standard tolerance of plus/minus 5%. The device supports a steady-state power dissipation of 2 watts at lead temperatures below 60°C and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum Zener impedance of 7.0 ohms at a test current of 33.4 mA and a maximum reverse current of 0.25 µA at 11.4 V. The component is RoHS compliant and available in tape and reel packaging.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands surge stresses and high specified maximum currents when adequately heat sunk
• Features flexible axial-lead mounting terminals for through-hole applications
• Nonsensitive to electrostatic discharge per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation circuits requiring 15 V reference
• Power supply protection against transient overvoltages
• General-purpose clamping and switching applications

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications: 'e3' indicates RoHS compliance, while 'TR12' specifies tape and reel packaging. Confirm the manufacturer designation as Microsemi Corporation or its successor entity. Ensure the part number corresponds to the 2EZ15D5 variant with the specific tolerance and package requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 15 V Zener voltage with 5% tolerance in an axial-lead package. Consider the thermal resistance of 45°C/W junction-to-lead when designing for full power operation. Verify compatibility with FR4 printed circuit boards if utilizing the ambient thermal resistance rating of 105°C/W. Ensure adequate heat sinking is provided to maintain performance within the specified operating temperature limits.

Single Zener Diodes Part Context

This component belongs to the 2EZ3.6D5 thru 2EZ200D5 series of silicon Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltage ratings from 3.6 V to 200 V in a standardized DO-41 plastic package. The product line includes options for various tolerances and military screening levels, providing flexibility for diverse electronic design requirements.

Single Zener Diodes Replacement Considerations

Surface mount equivalents are available in the SMBJ2EZ3.6D5 to SMBJ2EZ200D5 series using the DO-214AA package, or the SMBG2EZ3.6D5 to SMBG200D5 series using the DO-215AA package. These alternatives offer similar electrical characteristics in a surface-mount form factor.
