Product details
Overview
1N6030UR/TR from Microsemi is a surface-mount 500 mW Zener diode with nominal Zener voltage of 180 V, ±5% tolerance (B-suffix), 1.0 mA maximum reverse leakage at 144 V, and dynamic impedance of 2350 Ω at 1.0 mA test current. It regulates voltage in precision reference and overvoltage protection circuits across industrial power supplies and instrumentation.
For engineers reviewing the 1N6030UR/TR datasheet, 1N6030UR/TR pinout, 1N6030UR/TR application, or 1N6030UR/TR equivalent, this page delivers verified electrical parameters, DO-213AA package details, thermal derating behavior, Zener impedance vs. voltage trends, and RoHS-compliant commercial-grade sourcing options.
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 for lead temperature of 30°C. Its Zener voltage exhibits +0.110 %/°C temperature coefficient and maintains stable regulation over -65°C to +175°C junction temperature range.
The DO-213AA glass MELF package provides hermetic sealing, metallurgical bonding, and minimal parasitic capacitance - critical for low-noise analog references and ESD-insensitive applications per MIL-STD-750 Method 1020.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6030AUR/TR | ±10% Zener tolerance (A-suffix) vs. ±5% (B-suffix); otherwise identical electrical specs and package | Acceptable where system-level tolerance budget allows looser regulation accuracy | Select 1N6030AUR/TR only if cost sensitivity outweighs need for tighter voltage control |
| BZX85C180 | DO-41 axial package; 1.3 W power rating; ±5% tolerance; 1000 Ω ZZT at 5 mA | Requires through-hole assembly and larger board area; better suited for higher-power dissipation | Choose BZX85C180 only when thermal headroom exceeds 0.5 W and PCB layout permits axial components |
Compared with 1N6030UR/TR, the 1N6030AUR/TR trades regulation accuracy for cost, while BZX85C180 offers higher power handling in a non-surface-mount form factor - neither is pin-compatible, and both require layout or thermal redesign.

FAQ
What is the Zener voltage tolerance for 1N6030UR/TR?
The 1N6030UR/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 lead temperature of 30°C, as confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0228-1 Rev. 1.
Is 1N6030UR/TR RoHS compliant?
Yes, the 1N6030UR/TR is RoHS compliant (e3 marking), with matte-tin end-cap plating. RoHS compliance applies only to the commercial-grade version - military-screened variants (e.g., JANTXV) are not RoHS compliant per Microsemi documentation in the "Part Nomenclature" section.
What is the maximum reverse leakage current for 1N6030UR/TR?
The maximum reverse leakage current for 1N6030UR/TR is 0.1 µA at 144 V (80% of nominal Zener voltage), as specified in the Electrical Characteristics table. This low leakage supports high-impedance reference and sensing applications without introducing significant error currents.
Does 1N6030UR/TR have a defined temperature coefficient?
Yes, the 1N6030UR/TR has a typical temperature coefficient of +0.110 %/°C, consistent across the 160–200 V portion of the 1N5985BUR–1N6031BUR family. This value quantifies how much the Zener voltage shifts per degree Celsius change in junction temperature.
What package type does 1N6030UR/TR use?
The 1N6030UR/TR uses the DO-213AA (SOD-80 / MLL34) glass MELF package - a hermetically sealed, surface-mount cylindrical package with metallurgically bonded end caps. Dimensions are 1.60–1.70 mm diameter (A) and 3.30–3.70 mm length (B), per the Package Dimensions drawing on page 5.
