Product details
Overview
1N4713UR-1/TR from Microsemi is a 30 V, ±5% tolerance, 500 mW surface-mount Zener diode in DO-213AA (SOD80/MLL34) MELF package, tested at 50 µA Zener current, with 0.30 V voltage regulation and 0.01 µA reverse leakage at 22.8 V, used for precision voltage reference and overvoltage protection in power supply feedback loops.
For engineers reviewing the 1N4713UR-1/TR datasheet, 1N4713UR-1/TR pinout, 1N4713UR-1/TR application, or 1N4713UR-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-compliant matte-tin plating option, and MIL-PRF-19500 up-screening availability.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-biased mode, leveraging silicon Zener breakdown at 30 V nominal with tight 5% tolerance maintained across -65 °C to +175 °C junction temperature range. Its metallurgically bonded die construction ensures stable long-term voltage regulation under thermal cycling.
The DO-213AA package enables high-reliability surface-mount assembly with 260 °C solder tolerance and minimal parasitic capacitance-critical for noise-sensitive analog references and stable feedback networks in DC-DC converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30.0 V ±5% at IZT = 50 µA - defines precise regulation point for feedback sensing |
| Power Dissipation (PD) | 0.5 W - supports continuous operation in compact SMT layouts without forced cooling |
| Voltage Regulation (∆VZ) | 0.30 V - indicates low dynamic impedance for stable output under varying load currents |
| Reverse Leakage (IR) | 0.01 µA at 22.8 V - ensures negligible error current in high-impedance reference paths |
| Thermal Resistance (RθJL) | 100 °C/W - enables predictable junction temperature rise when mounted on FR4 with recommended footprint |
| Junction Temperature Range | -65 °C to +175 °C - suitable for aerospace, industrial, and downhole electronics environments |
| Package | DO-213AA (SOD80/MLL34) MELF - hermetically sealed glass body with end-cap terminations for reliability and moisture resistance |
Pinout & Package

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55C30 (Vishay) | 30 V ±5%, 500 mW, DO-35 axial package; higher RθJA (500 °C/W); no MIL-PRF-19500 screening | Not suitable for surface-mount-only PCBs; limited to through-hole assembly and lower thermal performance | Select only if DO-35 footprint is already standardized and up-screening is unnecessary |
| MMBZ5257B (ON Semiconductor) | 30 V ±5%, 350 mW, SOT-23 package; 10 µA IZT; higher leakage (1 µA at 24 V) | Lower power handling and higher leakage reduce accuracy in precision references; unsuitable for high-temp operation beyond 150 °C | Choose only for space-constrained consumer designs where cost and size outweigh stability and reliability needs |

FAQ
What is the Zener voltage tolerance of the 1N4713UR-1/TR?
The 1N4713UR-1/TR has a nominal Zener voltage of 30.0 V with a standard tolerance of ±5%, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0240-1 Rev. 2. Tighter 2% and 1% tolerances are available under different part number suffixes (C and D), but the 1N4713UR-1/TR itself is ±5%.
Is the 1N4713UR-1/TR RoHS compliant?
Yes, the 1N4713UR-1/TR is available in RoHS-compliant version with matte-tin plating (designated by "e3" in nomenclature), though this option is restricted to commercial-grade devices only. The base part number does not imply RoHS compliance-confirmation requires checking the full marking or ordering code with e3 suffix.
What is the maximum steady-state power dissipation for the 1N4713UR-1/TR?
The 1N4713UR-1/TR is rated for 0.5 W steady-state power dissipation when mounted on FR4 board with 1 oz copper and within ambient temperature limits (TA < 50 °C) or end-cap temperature limits (TEC < 125 °C), per the Maximum Ratings table on page 1 of the datasheet.
Does the 1N4713UR-1/TR support MIL-PRF-19500 up-screening?
Yes, the 1N4713UR-1/TR is eligible for up-screening per MIL-PRF-19500, as explicitly stated in the Features section on page 1. Screening levels (e.g., JAN, JANTX, JANTXV, JANS) are designated by prefix letters in the full part number, and require factory consultation for availability and qualification documentation.
What is the reverse leakage current specification for the 1N4713UR-1/TR?
The 1N4713UR-1/TR exhibits a maximum reverse leakage current (IR) of 0.01 µA at 22.8 V (76% of VZ), measured at 25 °C. This ultra-low leakage is critical for maintaining accuracy in high-impedance voltage divider networks used in precision reference applications.
