Product details
Overview
1N6016UR/TR from Microsemi is a surface-mount 500 mW Zener diode in DO-213AA (MLL34/SOD80) MELF package, rated for 47 V nominal Zener voltage at 2.0 mA test current, with ±5% tolerance (B suffix), 170 Ω dynamic impedance at IZT, and maximum reverse leakage of 0.1 µA at 36 V. It regulates voltage in precision reference and overvoltage protection circuits across industrial power supplies.
For engineers reviewing the 1N6016UR/TR datasheet, 1N6016UR/TR pinout, 1N6016UR/TR application, or 1N6016UR/TR equivalent, key selection criteria include Zener voltage accuracy, low leakage at rated VR, thermal resistance (300 °C/W junction-to-ambient), RoHS compliance status, and DO-213AA footprint compatibility with automated SMT assembly.
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 specified dynamic impedance (ZZT = 170 Ω) measured at 1 kHz with 10% rms AC current superimposed on DC bias. Its temperature coefficient is +0.096 %/°C, indicating positive drift above 25 °C.
The 1N6016UR/TR uses hermetically sealed glass construction with metallurgically bonded end caps, enabling stable operation from –65 °C to +175 °C junction temperature and inherent radiation hardness per MicroNote 050. Polarity is marked by a cathode band, requiring the banded end to be held positive relative to the anode during regulation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 47 V at 2.0 mA - defines regulation setpoint under standard test conditions |
| Power Dissipation (PD) | 0.5 W at 25 °C ambient - limits continuous DC power handling on FR4 board |
| Zener Impedance (ZZT) | 170 Ω at IZT - determines output voltage variation under load current changes |
| Reverse Leakage Current (IR) | 0.1 µA at 36 V - ensures minimal standby current in high-impedance bias networks |
| Temperature Coefficient (αVZ) | +0.096 %/°C - quantifies voltage drift magnitude per degree Celsius rise |

| Package Type | DO-213AA (MLL34/SOD80) - cylindrical MELF glass package optimized for thermal performance and reliability |
Pinout & Package
DO-213AA (MLL34/SOD80) is a hermetically sealed glass MELF package with two metallized end caps serving as anode and cathode terminals. Cathode is identified by a single dark band. No internal leads or die attach wires - direct end-cap conduction path minimizes parasitic inductance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Regulated output node | Connected to higher-potential rail; reverse-biased terminal where Zener breakdown occurs |
| Anode (unbanded end) | Reference return node | Connected to lower-potential rail or ground; completes current path during regulation |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass MELF construction | Enables long-term stability and moisture resistance without conformal coating |
| Metallurgically bonded end caps | Eliminates wire bonds, improving thermal cycling reliability and reducing failure modes |
| RoHS-compliant matte-tin plating | Supports lead-free reflow soldering per JEDEC J-STD-020, compatible with 260 °C peak profile |
| Non-sensitive to ESD | Withstands >8 kV HBM per MIL-STD-750 Method 1020 without parameter shift |
| Inherent radiation hardness | Qualified per Microsemi MicroNote 050 for TID tolerance up to 100 krad(Si) |
Applications
| Industrial Power Supply Reference | Overvoltage Protection Clamp |
|---|---|
Use Scenario: Precision voltage reference in isolated DC-DC converter feedback loops operating from –40 °C to +125 °C ambient. IC Role / Device Role / Timing Role: Zener diode provides stable 47 V reference for optocoupler-based error amplification. Use Value: Low 0.1 µA leakage at 36 V prevents loading of high-impedance divider networks; +0.096 %/°C TC enables predictable compensation. | Use Scenario: Transient voltage clamp protecting 48 V telecom line interface ICs against lightning-induced surges. IC Role / Device Role / Timing Role: Shunts excess energy to ground when line voltage exceeds 47 V breakdown threshold. Use Value: 0.5 W power rating sustains 100 ms surge events; DO-213AA thermal resistance (300 °C/W) limits junction temperature rise below 150 °C. |
| Test Equipment Calibration Standard | Aerospace Sensor Bias Network |
Use Scenario: Fixed-voltage reference in portable multimeter front-end circuitry requiring traceable accuracy and low drift. IC Role / Device Role / Timing Role: Provides known 47 V reference for ADC full-scale calibration and offset trimming. Use Value: ±5% tolerance (B suffix) and 170 Ω ZZT ensure <±0.1% reading error across 1–10 mA operating range. | Use Scenario: Stable bias source for radiation-hardened pressure transducers in satellite payload modules. IC Role / Device Role / Timing Role: Supplies regulated excitation voltage to piezoresistive bridge elements. Use Value: Inherent radiation hardness (MicroNote 050) and –65 °C to +175 °C operation eliminate need for derating or shielding. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6016UR-1 | Tape-and-reel not specified; supplied in bulk or ammo pack; same electrical specs and DO-213AA package | Lacks TR suffix - not optimized for high-speed pick-and-place; requires manual loading or reel conversion | Select 1N6016UR/TR when automated SMT placement is required; choose 1N6016UR-1 only for prototyping or low-volume hand assembly |
| BZX84-C47 | SOT-23 package (3.0 × 1.4 × 1.1 mm), 350 mW rating, 47 V ±5%, ZZT = 130 Ω at 5 mA | Lower power and smaller footprint; unsuitable for >350 mW dissipation or high-reliability hermetic requirements | Choose BZX84-C47 only for space-constrained consumer designs where radiation hardness and 0.5 W capability are not needed |
Compared with 1N6016UR/TR, 1N6016UR-1 shares identical electrical behavior but lacks tape-and-reel packaging for SMT lines, while BZX84-C47 trades hermetic reliability and power margin for compactness and cost-making it viable only in non-critical commercial applications.

FAQ
What is the Zener voltage tolerance of the 1N6016UR/TR?
The 1N6016UR/TR has a nominal Zener voltage of 47 V with ±5% tolerance, indicated by the "B" suffix in its part nomenclature per Microsemi's T4-LDS-0228-1 specification. This means the actual VZ falls between 44.65 V and 49.35 V when measured at 2.0 mA test current and 30 °C lead temperature. The 1N6016UR/TR maintains this tolerance across its qualified operating temperature range.
Is the 1N6016UR/TR RoHS compliant?
Yes, the 1N6016UR/TR is RoHS compliant, as confirmed by the "e3" designation in its full part number per Microsemi documentation. It features matte-tin plating on its end caps and meets EU Directive 2011/65/EU requirements. RoHS compliance applies only to commercial-grade versions; military-screened variants (e.g., JANTXV) are not RoHS compliant.
What is the maximum reverse leakage current for the 1N6016UR/TR?
The 1N6016UR/TR exhibits a maximum reverse leakage current (IR) of 0.1 µA at 36 V, as specified in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0228-1 datasheet. This low leakage ensures minimal current draw in high-impedance reference networks and supports stable operation in battery-powered or ultra-low-power systems using the 1N6016UR/TR.
Does the 1N6016UR/TR have a specified forward voltage?
Yes, the 1N6016UR/TR has a maximum forward voltage (VF) of 1.1 V at 200 mA, per the Maximum Ratings table in Microsemi's T4-LDS-0228-1 datasheet. This value reflects the diode's behavior in forward conduction mode and is relevant for applications where the device may experience brief forward bias during transient events or startup sequencing involving the 1N6016UR/TR.
What package type does the 1N6016UR/TR use, and what are its key mechanical features?
The 1N6016UR/TR uses the DO-213AA (also designated MLL34 or SOD80) glass MELF package - a hermetically sealed cylindrical form with metallurgically bonded tin-lead or RoHS-compliant matte-tin end caps. Key features include 0.04 g weight, 1.60–1.70 mm diameter (A), and 3.30–3.70 mm length (B), supporting reliable automated placement and high thermal performance for the 1N6016UR/TR.
