Product details
Overview
1N4715UR-1/TR from Microsemi is a 36 V, ±5% tolerance, 500 mW surface-mount Zener diode in DO-213AA (SOD-80/MLL34) MELF package, tested at 50 µA, with 0.36 V voltage regulation and 0.01 µA reverse leakage at 27.3 V, used for precision voltage reference and overvoltage protection in power supply feedback loops.
For engineers reviewing the 1N4715UR-1/TR datasheet, 1N4715UR-1/TR pinout, 1N4715UR-1/TR application, or 1N4715UR-1/TR equivalent, key selection criteria include Zener voltage accuracy at low test current, hermetic glass packaging for reliability, thermal resistance (100 °C/W junction-to-end cap), RoHS compliance (e3 marking), and MIL-PRF-19500 up-screening eligibility.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-biased mode, leveraging silicon Zener breakdown with metallurgically bonded die construction for stable performance across -65 °C to +175 °C junction temperature range. Its low 50 µA test current enables operation in ultra-low-power bias networks without significant loading.
The DO-213AA glass MELF package provides hermetic sealing and minimal parasitic capacitance (typical <1.5 pF at 0 V), supporting high-frequency stability in reference and clamping circuits. Thermal resistance values (RθJL = 100 °C/W, RθJA = 250 °C/W) define derating behavior on FR4 PCBs with standard footprint.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C36LT1G | 36 V, ±5%, SOT-23 package, 350 mW rating, 5 mA test current | Higher IZT increases bias current demand; plastic package lacks hermeticity | Select for cost-sensitive, non-hermetic consumer designs where board space is constrained |
| MMBZ5245B-7-F | 36 V, ±5%, SOT-23, 225 mW, 10 mA test current, higher leakage (~1 µA) | Lower power rating and higher leakage limit use in precision low-power systems | Prefer only in legacy SOT-23 layouts where DO-213AA rework is impractical |

FAQ
What is the Zener voltage and tolerance of the 1N4715UR-1/TR?
The 1N4715UR-1/TR has a nominal Zener voltage of 36 V with a tolerance of ±5% at 50 µA test current. This value is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0240-1 Rev. 2 datasheet. The 1N4715UR-1/TR maintains this specification across its qualified operating temperature range and is available in tighter 2% and 1% tolerances under different part number suffixes.
What package type does the 1N4715UR-1/TR use, and is it RoHS compliant?
The 1N4715UR-1/TR uses the DO-213AA (SOD-80/MLL34) glass MELF package, which is hermetically sealed and features metallurgically bonded die construction. It is RoHS compliant when ordered with the "e3" suffix (e.g., 1N4715UR-1/TR e3), as stated in the Part Nomenclature section. Standard commercial versions without "e3" use tin-lead plating.
What is the maximum reverse leakage current for the 1N4715UR-1/TR, and at what voltage is it specified?
The maximum reverse leakage current for the 1N4715UR-1/TR is 0.01 µA, specified at a reverse voltage (VR) of 27.3 V, per the Electrical Characteristics table. This ultra-low leakage supports high-impedance bias networks and precision reference applications where current draw must be minimized without compromising regulation accuracy.
Can the 1N4715UR-1/TR be used in high-reliability or aerospace applications?
Yes-the 1N4715UR-1/TR supports MIL-PRF-19500 up-screening per the Features section, and its hermetic DO-213AA package and metallurgical die bond provide inherent radiation hardness documented in Microsemi's MicroNote 050. These attributes make the 1N4715UR-1/TR suitable for aerospace, defense, and other high-reliability applications requiring long-term parametric stability.
What is the thermal resistance and power derating behavior of the 1N4715UR-1/TR?
The 1N4715UR-1/TR has a junction-to-end cap thermal resistance (RθJL) of 100 °C/W and junction-to-ambient (RθJA) of 250 °C/W when mounted on FR4 with recommended footprint. Its rated 0.5 W dissipation applies only below 125 °C end-cap temperature or 50 °C ambient; Figure 1 in the datasheet shows linear derating above those thresholds.
