Product details
Overview
1N6022UR/TR from Microsemi is a surface-mount 500 mW Zener diode with nominal Zener voltage of 82 V, ±5% tolerance (B-suffix), 2.0 mA test current, and dynamic impedance of 280 Ω at IZT. It regulates voltage in power supply reference and overvoltage protection circuits across industrial temperature range.
For engineers reviewing the 1N6022UR/TR datasheet, 1N6022UR/TR pinout, 1N6022UR/TR application, or 1N6022UR/TR equivalent, key selection factors include Zener voltage accuracy, thermal resistance (300 °C/W), low leakage (<0.1 µA at 65.6 V), RoHS-compliant matte-tin plating, and DO-213AA MELF package suitability for high-reliability PCB layouts.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with regulation defined at IZT = 2.0 mA and VZ = 82 V. Its 280 Ω dynamic impedance (ZZT) and +0.098 %/°C temperature coefficient ensure stable reference performance under varying load and ambient conditions.
The DO-213AA glass MELF package provides hermetic sealing, metallurgical bonding, and compatibility with automated SMT assembly. Thermal resistance junction-to-ambient is 300 °C/W on FR4 board - critical for power derating above 25 °C ambient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 82 V ±5% at 2.0 mA - defines precise regulation point for feedback loops and clamping thresholds |
| Power Dissipation (PD) | 0.5 W at 25 °C - sets maximum continuous power handling before thermal derating applies |
| Dynamic Impedance (ZZT) | 280 Ω at 2.0 mA - determines output voltage variation under load current changes |
| Reverse Leakage (IR) | <0.1 µA at 65.6 V - ensures minimal standby current in high-impedance bias networks |
| Temp. Coefficient (αVZ) | +0.098 %/°C - quantifies voltage drift per degree Celsius for precision reference design |
| Junction Temp. Range | –65 to +175 °C - supports operation in extended industrial and aerospace environments |
| Package | DO-213AA (SOD80/MLL34) - glass MELF with end-cap terminations for high reliability and thermal stability |
Pinout & Package
DO-213AA (SOD80/MLL34) glass MELF package with hermetically sealed construction, tin-lead or RoHS-compliant matte-tin end-cap plating, and cathode band marking. Polarity: banded end is cathode (positive terminal during Zener operation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Zener anode connection point | Connected to higher potential node; reverse-biased to enable breakdown regulation |
| Anode (unbanded end) | Zener cathode connection point | Connected to lower potential node (e.g., ground or return path); completes bias circuit |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount DO-213AA package | Enables automated placement and reflow soldering while maintaining hermetic reliability |
| Metallurgically bonded construction | Ensures robust interfacial integrity and long-term stability under thermal cycling |
| Non-sensitive to ESD (MIL-STD-750, Method 1020) | Eliminates need for special ESD handling during assembly and field operation |
| Inherently radiation-hardened | Validated per Microsemi MicroNote 050 for TID tolerance in space and nuclear environments |
| RoHS-compliant option (e3 suffix) | Matte-tin plating meets EU RoHS Directive 2011/65/EU for commercial-grade variants |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6022UR-1 | Same electrical specs but axial DO-35 (DO204AH) package; no tape-and-reel packaging | Requires through-hole mounting; unsuitable for high-density SMT layouts | Select when legacy board design mandates axial leaded form factor |
| BZX85C82 | 82 V ±5%, 1.3 W rating, DO-41 package; higher power but larger footprint and 500 Ω ZZT | Supports higher continuous current but lacks radiation hardness and MIL-PRF-19500 screening options | Select when thermal headroom >0.5 W is required and radiation tolerance is not needed |
Compared with 1N6022UR/TR, the 1N6022UR-1 offers identical regulation but requires manual or axial insertion, while BZX85C82 trades compact MELF reliability for higher power and relaxed impedance - making the TR variant optimal for space-constrained, high-reliability SMT designs.

FAQ
What is the Zener voltage tolerance of the 1N6022UR/TR?
The 1N6022UR/TR has a nominal Zener voltage of 82 V with ±5% tolerance, indicated by the "B" suffix in its part nomenclature. This means the actual measured VZ at 2.0 mA test current falls between 77.9 V and 86.1 V across the qualified lot, meeting JEDEC 1N6022 specification limits.
Is the 1N6022UR/TR RoHS compliant?
Yes, the 1N6022UR/TR is RoHS compliant, as confirmed by the "e3" designation in Microsemi documentation and its matte-tin end-cap plating. RoHS compliance applies only to commercial-grade versions; military-screened variants use tin-lead plating and are not RoHS compliant.
What does the "TR" suffix mean in 1N6022UR/TR?
The "TR" suffix in 1N6022UR/TR indicates tape-and-reel packaging per EIA-481-B standard using 12 mm carrier tape. This format enables automated pick-and-place assembly and is standard for high-volume SMT manufacturing, distinguishing it from bulk or ammo-pack variants.
What is the maximum reverse leakage current for the 1N6022UR/TR?
The maximum reverse leakage current (IR) for the 1N6022UR/TR is 0.1 µA at 65.6 V (80% of nominal VZ). This ultra-low leakage supports high-impedance bias networks and minimizes standby power loss in precision reference applications.
Can the 1N6022UR/TR be used in high-temperature environments?
Yes, the 1N6022UR/TR is rated for junction and storage temperatures from –65 °C to +175 °C. Its DO-213AA glass MELF package and metallurgical bonds maintain parameter stability across this full range, making it suitable for under-hood automotive, downhole oil/gas, and industrial control applications.
