Product details
Overview
1N6016UR-1/TR from Microsemi is a surface-mount 47 V, 5% tolerance Zener diode in DO-213AA (MLL34/SOD80) MELF package, rated for 500 mW power dissipation at 25°C, with 170 Ω dynamic impedance at 2 mA test current and ±0.096%/°C temperature coefficient - used for precision voltage regulation in power supply feedback loops and reference circuits.
For engineers reviewing the 1N6016UR-1/TR datasheet, 1N6016UR-1/TR pinout, 1N6016UR-1/TR application, or 1N6016UR-1/TR equivalent, key selection criteria include Zener voltage tolerance (±5%), low leakage (<0.1 µA at 37.6 V), thermal resistance (300°C/W), RoHS-compliant matte-tin plating, and tape-and-reel packaging (TR suffix).
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 47 V regulation across a wide current range (2 mA to 170 mA), with minimal capacitance and inherent radiation hardness per MicroNote 050. Its metallurgically bonded glass construction ensures high reliability under thermal cycling and mechanical stress.
The device exhibits a positive temperature coefficient (+0.096%/°C), enabling predictable drift compensation in temperature-sensitive references. It complies with MIL-PRF-19500 screening levels when ordered with appropriate prefixes and meets ESD immunity per MIL-STD-750 Method 1020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 47 V ±5% at 2 mA - defines nominal regulation point with tight tolerance for stable reference accuracy |
| Power Dissipation (PD) | 0.5 W at 25°C ambient - sets maximum continuous power handling on FR4 board with 1 oz Cu |
| Dynamic Impedance (ZZT) | 170 Ω at IZT = 2 mA - determines regulation stiffness and output voltage ripple suppression |
| Reverse Leakage (IR) | <0.1 µA at 37.6 V - ensures minimal error current in high-impedance bias networks |
| Temp. Coefficient (αVZ) | +0.096 %/°C - enables predictable voltage drift for temperature-compensated designs |
| Thermal Resistance (RθJA) | 300 °C/W - defines junction-to-ambient temperature rise per watt, critical for thermal design margin |
| Package | DO-213AA (MLL34/SOD80) MELF - hermetically sealed glass surface-mount package with end-cap terminations |
Pinout & Package
DO-213AA (MLL34/SOD80) is a cylindrical MELF-style glass package with two metallized end caps serving as anode and cathode terminals. Cathode is marked by a single band; operation requires cathode to be biased positive relative to anode for Zener conduction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Zener regulation terminal | Connected to higher potential node; reverse-biased to achieve 47 V breakdown regulation |
| Anode (unbanded end) | Reference return terminal | Connected to circuit ground or lower-potential node; completes Zener current path |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass MELF construction | Enables operation from –65°C to +175°C junction temperature with no moisture ingress or parameter shift |
| Metallurgically bonded terminations | Provides robust mechanical and thermal interface to PCB pads, supporting reflow and thermal cycling reliability |
| RoHS-compliant matte-tin plating | Ensures solderability per MIL-STD-750 Method 2026 without lead-based alloys, compatible with Pb-free assembly |
| Inherent radiation hardness | Validated per Microsemi MicroNote 050 - suitable for aerospace and high-reliability terrestrial applications |
| Low capacitance profile | Typical <2 pF - minimizes signal coupling and phase shift in high-frequency feedback paths |
Applications
| Switch-Mode Power Supply Feedback | Industrial Sensor Reference |
|---|---|
Use Scenario: Regulating output voltage in isolated flyback or forward converters via optocoupler-coupled feedback loop. IC Role / Device Role / Timing Role: Zener reference element setting precise 47 V threshold for TL431 or similar shunt regulator input.

IC Role / Device Role / Timing Role: Stable reference input to LM393 or similar comparator for detecting overvoltage thresholds. Use Value: Low capacitance (<2 pF) prevents signal delay; hermetic sealing ensures long-term stability in humid environments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX84-C47 | 47 V ±5%, SOT-23 package, 300 mW rating, 190 Ω ZZT at 5 mA | Lower power rating and higher dynamic impedance; not suitable for >150 mA regulation loads | Select when board space is constrained and power demand ≤300 mW; verify thermal derating on thin PCBs |
| 1N4750A | 47 V ±5%, DO-41 axial package, 1 W rating, 170 Ω ZZT at 13 mA | Higher power capability but through-hole mounting; incompatible with automated SMT assembly | Select when higher power dissipation (>500 mW) or manual prototyping is required; not drop-in for SMT production |
Compared with BZX84-C47 and 1N4750A, the 1N6016UR-1/TR delivers identical voltage accuracy and comparable dynamic impedance while offering surface-mount compatibility, hermetic reliability, and radiation-hardened performance - making it optimal for high-density, high-reliability industrial and aerospace power regulation.

FAQ
What is the Zener voltage tolerance of the 1N6016UR-1/TR?
The 1N6016UR-1/TR has a Zener voltage tolerance of ±5% at 47 V, tested at 2 mA. This corresponds to the "B" suffix in Microsemi's nomenclature and ensures regulation remains within 44.65 V to 49.35 V under specified conditions, critical for stable feedback loop design.
Is the 1N6016UR-1/TR RoHS compliant?
Yes, the 1N6016UR-1/TR is RoHS compliant (e3 marking), featuring matte-tin plating on its DO-213AA end caps. RoHS compliance applies only to commercial-grade versions; military-screened variants use tin-lead plating and are not RoHS compliant.
What is the maximum Zener current (IZM) for the 1N6016UR-1/TR?
The maximum dc Zener current for the 1N6016UR-1/TR is 170 mA at 25°C ambient, calculated from its 500 mW power rating and 47 V nominal Zener voltage. Derating is required above 25°C per the published power derating curve in Figure 1.
Does the 1N6016UR-1/TR have a cathode band marking?
Yes, the 1N6016UR-1/TR uses a single cathode band on the glass body to identify the cathode terminal. The banded end must be connected to the higher-potential node for proper Zener regulation; polarity reversal will result in forward conduction at ~1.1 V.
What is the thermal resistance junction-to-ambient (RθJA) for the 1N6016UR-1/TR?
The thermal resistance junction-to-ambient (RθJA) for the 1N6016UR-1/TR is 300°C/W when mounted on a standard FR4 PCB with 1 oz copper and the recommended footprint. This value assumes natural convection cooling and defines the temperature rise per watt of dissipated power.
