Product details
Overview
1N6022UR-1/TR from Microsemi is a surface-mount 82 V, 500 mW Zener diode in DO-213AA (MLL34/SOD80) MELF package with ±5% voltage tolerance, 2 mA test current, and 280 Ω dynamic impedance at IZT; used for precision voltage regulation in power supply feedback loops and overvoltage protection circuits.
For engineers reviewing the 1N6022UR-1/TR datasheet, 1N6022UR-1/TR pinout, 1N6022UR-1/TR application, or 1N6022UR-1/TR equivalent, this page delivers verified electrical parameters, thermal derating behavior, RoHS-compliant plating details, and direct alternatives for industrial power management design.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with Zener voltage specified at 2 mA test current (IZT) and characterized across -65°C to +175°C junction temperature range. Its 280 Ω dynamic impedance (ZZT) at IZT and 0.098%/°C temperature coefficient define regulation stability under varying load and thermal conditions.
The DO-213AA glass MELF package provides hermetic sealing and metallurgical bonding for high-reliability operation, supporting solder reflow up to 260°C for 10 seconds. Thermal resistance junction-to-ambient is 300°C/W on FR4 board with 1 oz copper, limiting continuous power dissipation to 0.5 W at TA ≤ 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 82 V ±5% at 2 mA - defines nominal regulation point with tight tolerance for stable reference in feedback networks. |
| Power Dissipation (PD) | 0.5 W at 25°C ambient - sets maximum continuous DC power handling before thermal derating applies. |
| Dynamic Impedance (ZZT) | 280 Ω at IZT = 2 mA - indicates voltage variation per mA change in Zener current; critical for ripple rejection. |
| Reverse Leakage (IR) | 0.1 µA at 65.6 V - ensures minimal parasitic current below breakdown, preserving efficiency in low-power standby modes. |
| Temp. Coefficient (αVZ) | +0.098 %/°C - quantifies voltage drift with temperature; enables compensation in wide-temperature-range designs. |
| Forward Voltage (VF) | 1.1 V at 200 mA - defines conduction threshold in forward bias; relevant for polarity protection or clamping configurations. |
| Junction Temp. Range | -65°C to +175°C - supports operation in harsh environments including automotive under-hood and industrial motor drives. |

FAQ
What is the Zener voltage tolerance and test current for the 1N6022UR-1/TR?
The 1N6022UR-1/TR has a nominal Zener voltage of 82 V with ±5% tolerance, measured at a test current (IZT) of 2 mA. This tolerance is defined per JEDEC standard and confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0228-1 datasheet. The 2 mA test point ensures stable regulation performance in typical feedback and clamp applications where current remains within 1–10 mA range.
Is the 1N6022UR-1/TR RoHS compliant?
Yes, the 1N6022UR-1/TR is RoHS compliant when ordered with the "e3" suffix (e.g., 1N6022UR-1/TR e3), indicating matte-tin end-cap plating. Per the datasheet, RoHS compliance applies to commercial-grade versions only; military-screened variants retain tin-lead plating. The "TR" suffix denotes tape-and-reel packaging per EIA-481-B standard, independent of RoHS status.
What is the maximum power dissipation and thermal derating behavior of the 1N6022UR-1/TR?
The 1N6022UR-1/TR has a rated power dissipation of 0.5 W at 25°C ambient temperature when mounted on FR4 PCB with 1 oz copper. Derating begins linearly above 25°C, reaching zero power at 125°C ambient per the curve in Figure 1. Junction-to-ambient thermal resistance is 300°C/W, meaning a 150°C rise occurs at full 0.5 W - confirming safe operation within its -65°C to +175°C junction temperature range.
Does the 1N6022UR-1/TR have radiation-hardened characteristics?
Yes, the 1N6022UR-1/TR exhibits inherent radiation hardness as documented in Microsemi MicroNote 050. Its glass-encapsulated DO-213AA structure and silicon process provide tolerance to total ionizing dose (TID) without requiring special qualification testing - a key differentiator for satellite power systems, nuclear instrumentation, and high-altitude avionics where single-event effects must be minimized.
What is the reverse leakage current specification for the 1N6022UR-1/TR?
The 1N6022UR-1/TR specifies a maximum reverse leakage current (IR) of 0.1 µA at 65.6 V (80% of nominal 82 V). This value is measured at 30°C lead temperature and reflects minimal off-state conduction, critical for maintaining efficiency in low-quiescent-current applications such as battery-backed sensors or always-on protection circuits.
