Product details
Overview
1N6030UR-1/TR from Microsemi is a surface-mount 500 mW Zener diode with nominal Zener voltage of 180 V, ±5% tolerance (B-suffix), 1.0 µA maximum reverse leakage at 144 V, and dynamic impedance of 2350 Ω at 1.0 mA test current. It regulates voltage in power supply reference and overvoltage protection circuits operating from -65°C to +175°C.
For engineers reviewing the 1N6030UR-1/TR datasheet, 1N6030UR-1/TR pinout, 1N6030UR-1/TR application, or 1N6030UR-1/TR equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (300°C/W junction-to-ambient), low capacitance (<1 pF typical), RoHS compliance (e3 suffix), and DO-213AA MELF package suitability for high-reliability industrial and aerospace designs.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with regulation defined at IZT = 1.0 mA and specified across a wide temperature range (-65°C to +175°C). Its metallurgically bonded glass DO-213AA package ensures hermetic sealing and radiation hardness per MicroNote 050.
It exhibits a positive temperature coefficient of +0.110 %/°C and maintains stable regulation under varying load currents, with maximum Zener current IZM = 137 mA derived from PD/VZM (0.5 W / 189 V). Reverse leakage remains ≤0.1 µA up to 144 V at 30°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 180 V ±5% at 1.0 mA - defines precise regulation point for high-voltage reference design |
| Power Dissipation (PD) | 0.5 W at 25°C - sets maximum continuous power handling on FR4 board with derating above 25°C |
| Dynamic Impedance (ZZT) | 2350 Ω at 1.0 mA - indicates voltage regulation stability under small-signal AC ripple |
| Reverse Leakage (IR) | ≤0.1 µA at 144 V - ensures minimal standby current in high-impedance bias networks |
| Junction Temperature Range | -65°C to +175°C - supports operation in extreme environments including downhole and avionics |
| Thermal Resistance (RθJA) | 300°C/W - determines required PCB copper area and airflow for thermal management |
| Capacitance (Typ.) | <1 pF - enables use in high-frequency voltage clamping without signal distortion |
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 |
|---|---|---|---|
| 1N6030B-1 | Axial DO-35 package; same electrical specs but leaded form factor | Requires through-hole assembly; unsuitable for SMT-only production lines | Select when legacy board layout or manual repair favors axial leads |
| MMBZ5267B | 300 mW SOT-23 package; 180 V ±5%, but higher ZZT = 3000 Ω and lower IZM = 83 mA | Limited power handling; not rated for >125°C ambient or radiation environments | Select only for low-power, cost-sensitive consumer applications with no reliability requirements |
Compared with 1N6030UR-1/TR, the 1N6030B-1 offers identical regulation performance in axial format but sacrifices SMT compatibility, while the MMBZ5267B trades power capability, thermal robustness, and radiation tolerance for smaller footprint and lower cost in non-critical systems.

FAQ
What is the Zener voltage tolerance of the 1N6030UR-1/TR?
The 1N6030UR-1/TR has a nominal Zener voltage of 180 V with ±5% tolerance, indicated by the 'B' suffix in its part nomenclature. This means the actual measured VZ falls between 171 V and 189 V when tested at IZT = 1.0 mA and 30°C. The tolerance is guaranteed across the full operating temperature range of -65°C to +175°C.
Is the 1N6030UR-1/TR RoHS compliant?
Yes, the 1N6030UR-1/TR is RoHS compliant, as confirmed by the 'e3' suffix in its full designation and documented in Microsemi's T4-LDS-0228-1 datasheet. The matte-tin plating meets RoHS Directive 2011/65/EU requirements and is qualified for commercial-grade applications only.
What package type does the 1N6030UR-1/TR use?
The 1N6030UR-1/TR uses the DO-213AA (also known as SOD80 or MLL34) glass MELF package - a hermetically sealed, surface-mount cylindrical package with tin-lead or RoHS-compliant matte-tin end-cap plating. Its dimensions are 1.60–1.70 mm diameter and 3.30–3.70 mm length.
What is the maximum reverse leakage current for the 1N6030UR-1/TR?
The maximum reverse leakage current for the 1N6030UR-1/TR is 0.1 µA at 144 V and 30°C, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0228-1 datasheet. This low leakage supports high-impedance bias networks and precision reference applications.
Can the 1N6030UR-1/TR be used in radiation-intensive environments?
Yes, the 1N6030UR-1/TR is inherently radiation-hardened per Microsemi MicroNote 050, making it suitable for space, nuclear, and high-altitude applications. Its glass DO-213AA package and metallurgical construction provide proven total ionizing dose (TID) tolerance without requiring additional shielding or derating.
