Product details
Overview
1N6011UR/TR from Microsemi is a surface-mount 30 V, 5% tolerance Zener diode in DO-213AA (MLL34/SOD80) MELF package, rated for 500 mW power dissipation at 25°C, with 78 mA maximum Zener current (IZM), 600 Ω dynamic impedance (ZZT), and ±0.093%/°C temperature coefficient - used for precision voltage regulation in power supply feedback loops and reference circuits.
For engineers reviewing the 1N6011UR/TR datasheet, 1N6011UR/TR pinout, 1N6011UR/TR application, or 1N6011UR/TR equivalent, this page delivers verified electrical parameters, package dimensions, thermal derating behavior, RoHS-compliant plating details, and validated alternative parts for voltage reference design and replacement sourcing.
Technical Context
This Zener diode operates in reverse breakdown with cathode-banded polarity, requiring the banded end to be held positive relative to the anode for regulation. It exhibits low leakage (≤0.1 µA at 23 V) and stable regulation across -65°C to +175°C junction temperature range.
Its DO-213AA glass MELF package provides hermetic sealing, metallurgical bonding, and minimal capacitance (typical <2 pF at 1 MHz), supporting high-reliability applications where ESD immunity (MIL-STD-750, method 1020) and radiation hardness per MicroNote 050 are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 30 V ±5% at 5 mA test current - 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 before thermal derating applies. |
| Zener Impedance (ZZT) | 600 Ω at 5 mA - indicates regulation stiffness; lower values yield tighter voltage control under load variation. |
| Max Reverse Leakage (IR) | 0.1 µA at 23 V - ensures minimal parasitic current in off-state, critical for low-power bias networks. |
| Temp Coefficient (αVZ) | +0.093%/°C - quantifies voltage drift with temperature; enables compensation in precision analog circuits. |
| Junction Temp Range | -65°C to +175°C - supports operation in extended industrial, aerospace, and downhole environments. |
| Forward Voltage (VF) | 1.1 V at 200 mA - defines forward conduction threshold; relevant for polarity protection or dual-use circuit paths. |
Pinout & Package
DO-213AA (SOD80/MLL34) glass MELF package: hermetically sealed cylindrical body with tin-lead or RoHS-compliant matte-tin end-cap plating; cathode identified by single black band; weight 0.04 g; tape-and-reel packaging per EIA-481-B (12 mm tape).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Zener regulation terminal | Must be biased positive relative to anode to enter breakdown; serves as regulated output node in shunt configuration. |
| Anode (unbanded end) | Reference return terminal | Connected to system ground or lower-potential rail; completes Zener current path during regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Surface-mount MELF construction | Enables automated placement and reflow compatibility while maintaining hermetic reliability superior to plastic SMD packages. |
| Metallurgically bonded junction | Ensures long-term stability and low parameter drift under thermal cycling and high-reliability stress conditions. |
| ESD-insensitive design | Withstands >8 kV HBM per MIL-STD-750, method 1020 - eliminates need for external ESD protection in board-level designs. |
| Radiation-hardened structure | Meets requirements outlined in Microsemi MicroNote 050 - suitable for space-grade and nuclear instrumentation applications. |
| RoHS-compliant option | e3 suffix denotes matte-tin plating (commercial grade only), enabling compliance without sacrificing solderability or thermal performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C30LT1G | 30 V ±5%, SOT-23 package, 300 mW rating, 80 Ω ZZT, -65°C to +150°C range | Lower power rating and smaller footprint; higher ZZT limits regulation precision in high-current feedback paths | Select when board space is constrained and power demand stays below 150 mW; verify thermal margin on FR4. |
| MMBZ5257BLT1G | 30 V ±5%, SOT-23, 225 mW, 100 Ω ZZT, -55°C to +150°C, higher leakage (1 µA @ 24 V) | Higher leakage and narrower temp range reduce suitability for high-reliability or extended-temp applications | Prefer for cost-sensitive consumer designs where radiation hardness and ESD immunity are not required. |
Compared with BZX84-C30LT1G and MMBZ5257BLT1G, the 1N6011UR/TR offers higher power handling (500 mW vs ≤300 mW), superior thermal capability (+175°C vs ≤+150°C), lower leakage (0.1 µA vs ≥1 µA), and inherent radiation hardness - making it the only choice for aerospace, downhole, and military-grade voltage reference designs.

FAQ
What is the Zener voltage tolerance and test current for the 1N6011UR/TR?
The 1N6011UR/TR has a nominal Zener voltage of 30 V with ±5% tolerance, measured at a test current (IZT) of 5 mA. This tolerance ensures predictable regulation performance in feedback networks where reference stability directly impacts output accuracy.
Does the 1N6011UR/TR support RoHS compliance?
Yes - the "e3" suffix in the full part number (1N6011UR/TR) indicates RoHS-compliant matte-tin end-cap plating, available for commercial-grade units. Non-RoHS versions use tin-lead plating and omit the e3 designation.
What is the maximum Zener current (IZM) for the 1N6011UR/TR?
The 1N6011UR/TR supports a maximum Zener current (IZM) of 78 mA at 25°C ambient, calculated from its 0.5 W power rating and upper-tolerance Zener voltage (31.5 V). Derating applies above 25°C per Figure 1 in the datasheet.
How is polarity marked on the 1N6011UR/TR package?
The 1N6011UR/TR uses a single black cathode band on the DO-213AA glass MELF body to indicate polarity. During regulation, the banded (cathode) end must be held positive relative to the unbanded (anode) end - reversing polarity places the device in forward conduction.
Is the 1N6011UR/TR suitable for high-reliability screening per MIL-PRF-19500?
No - the "UR" suffix denotes the commercial-grade version. For MIL-PRF-19500 screening, prefixes such as MQ (JAN), MX (JANTX), or MV (JANTXV) must be added to the base part number (e.g., MQ1N6011BUR/TR); those variants undergo additional testing and qualification.
