Product details
Overview
1N6010UR-1/TR from Microsemi is a surface-mount 27 V, 5% tolerance Zener diode in DO-213AA (SOD80) MELF package, rated for 500 mW power dissipation at 25°C, with 70 mA maximum Zener current (IZM), 78 Ω dynamic impedance (ZZT) at 5 mA test current, and operating junction temperature range of –65°C to +175°C. It serves as a precision voltage reference or shunt regulator in low-power analog circuits.
For engineers reviewing the 1N6010UR-1/TR datasheet, 1N6010UR-1/TR pinout, 1N6010UR-1/TR application, or 1N6010UR-1/TR equivalent, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (300°C/W junction-to-ambient), low leakage (<0.1 µA at 21.6 V), RoHS-compliant matte-tin plating, and MELF package suitability for high-reliability industrial and aerospace PCB layouts.
Technical Context
This device operates as a silicon planar Zener diode with metallurgically bonded construction, designed for stable reverse-biased regulation across wide temperature and current ranges. Its DO-213AA glass-encapsulated MELF structure provides hermetic sealing and inherent radiation hardness per MicroNote 050.
Regulation occurs at IZT = 5 mA with VZ = 27 V ±5%, exhibiting ZZT = 78 Ω and αVZ = +0.091%/°C. Reverse leakage IR is limited to ≤0.1 µA at VR = 21.6 V (90% of VZ), and forward voltage VF is 1.1 V at 200 mA - confirming standard PN-junction behavior outside breakdown.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 27 V ±5% at 5 mA - defines nominal regulation point with tight tolerance for stable reference generation |
| Power Dissipation (PD) | 0.5 W at 25°C ambient - sets maximum continuous power handling on FR4 board with 1 oz Cu |
| Zener Impedance (ZZT) | 78 Ω at 5 mA - indicates small-signal AC resistance affecting regulation stability under varying load |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6010UR-1 | Same electrical specs but in bulk (non-tape-and-reel) packaging; no TR suffix | Lacks EIA-481-B tape-and-reel format - unsuitable for high-volume SMT pick-and-place lines | Select 1N6010UR-1/TR when automated assembly requires 12 mm carrier tape; choose 1N6010UR-1 for manual prototyping or low-volume hand-soldering |
| BZX55C27 | 27 V ±5% Zener in DO-35 axial package; 500 mW rating; higher ZZT (100 Ω) and wider tempco (±0.09%/°C) | Requires through-hole mounting and larger board area; less suitable for high-density or vibration-prone designs | Choose BZX55C27 only if legacy DO-35 footprint compatibility is mandatory; otherwise prefer 1N6010UR-1/TR for superior thermal performance and MELF reliability |
Compared with 1N6010UR-1 and BZX55C27, the 1N6010UR-1/TR delivers identical regulation performance in a surface-mount MELF package optimized for thermal dissipation (300°C/W RθJA), automated assembly, and radiation-hardened operation - making it the preferred choice for new industrial and aerospace designs requiring long-term stability and high-reliability packaging.

FAQ
What is the Zener voltage tolerance of the 1N6010UR-1/TR?
The 1N6010UR-1/TR has a Zener voltage tolerance of ±5% at 5 mA test current, meaning its actual regulation voltage falls between 25.65 V and 28.35 V under specified conditions. This tolerance is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0228-1 Rev. 1, where "B" suffix denotes 5% tolerance for the 1N6010BUR family, and the "UR" designation indicates the DO-213AA package variant.
Is the 1N6010UR-1/TR RoHS compliant?
Yes, the 1N6010UR-1/TR is RoHS compliant when ordered with the "e3" suffix (e.g., 1N6010UR-1/TR e3), indicating matte-tin end-cap plating. Per the "PART NOMENCLATURE" section on page 2 of T4-LDS-0228-1 Rev. 1, RoHS compliance is available for commercial-grade units only; non-RoHS versions use tin-lead plating and omit the "e3" identifier.
What is the maximum Zener current (IZM) for the 1N6010UR-1/TR?
The maximum Zener current (IZM) for the 1N6010UR-1/TR is 70 mA, calculated per Note 3 on page 4 using P = 0.5 W and VZM = 27 V × 1.05 = 28.35 V. This value is explicitly listed in the Electrical Characteristics table on page 3 under the "1N6010BUR" row for the "B,C,D Suffix" column, confirming 70 mA at 5 mA test current.
Does the 1N6010UR-1/TR have a defined forward voltage specification?
Yes, the 1N6010UR-1/TR specifies a maximum forward voltage (VF) of 1.1 V at 200 mA forward current, as stated in the "MAXIMUM RATINGS" table on page 1 of T4-LDS-0228-1 Rev. 1. This parameter enables polarity verification during functional testing and confirms standard silicon diode behavior outside Zener breakdown.
What package type does the 1N6010UR-1/TR use?
The 1N6010UR-1/TR uses the DO-213AA (also designated SOD80 or MLL34) MELF glass package - a hermetically sealed cylindrical surface-mount outline with tin-lead or RoHS-compliant matte-tin end-cap plating. This is confirmed in the "MECHANICAL and PACKAGING" section on page 2 and the "PACKAGE DIMENSIONS" drawing on page 5 of T4-LDS-0228-1 Rev. 1.
