Product details
Overview
1N6016BUR-1/TR from Microsemi is a surface-mount 500 mW Zener diode with nominal Zener voltage of 47 V, ±5% tolerance (B suffix), 2.0 mA test current, and dynamic impedance of 11 Ω at IZT. It regulates voltage in power supply reference and overvoltage protection circuits across industrial temperature range.
For engineers reviewing the 1N6016BUR-1/TR datasheet, 1N6016BUR-1/TR pinout, 1N6016BUR-1/TR application, or 1N6016BUR-1/TR equivalent, this page delivers verified package dimensions, thermal resistance values, reverse leakage limits, Zener impedance behavior, and RoHS-compliant commercial-grade availability.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with cathode band marking polarity. Its DO-213AA (SOD80/MLL34) MELF glass package enables stable thermal performance and low parasitic capacitance (typical <11 pF at 47 V).
It meets MIL-PRF-19500 screening requirements when ordered with MQ/MX/MV/CDS prefixes and exhibits inherent radiation hardness per MicroNote 050. The 150 °C/W junction-to-end-cap thermal resistance supports reliable operation up to +175 °C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 47 V ±5% at 2.0 mA test current - defines precise regulation point for feedback loops and voltage clamping |
| Power Dissipation | 0.5 W at 25 °C ambient - sets maximum continuous power handling on FR4 board with recommended footprint |
| Dynamic Impedance (ZZT) | 11 Ω at IZT = 2.0 mA - determines output voltage stability under varying load current |
| Reverse Leakage (IR) | ≤0.1 µA at 30 V - ensures minimal quiescent current in high-impedance bias networks |
| Junction Temperature Range | –65 °C to +175 °C - supports operation in extended industrial and aerospace environments |
| Thermal Resistance (RθJA) | 300 °C/W - informs derating curve for ambient temperatures above 25 °C |
| Forward Voltage (VF) | 1.1 V at 200 mA - relevant for ESD protection path conduction during forward transients |

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/TR (Microchip) | Same 47 V ±5%, but DO-213AB package; RθJA = 350 °C/W vs. 300 °C/W; no MIL-PRF-19500 screening path | Limited to commercial-grade industrial use; not qualified for aerospace or defense programs requiring MIL screening | Select when cost sensitivity outweighs need for military qualification or tighter thermal resistance |
| BZX84-C47LT1G (onsemi) | SOT-23 package; 47 V ±5%; 300 mW rating; ZZT = 90 Ω at 5 mA - significantly higher impedance than 1N6016BUR-1/TR | Lower power handling and higher dynamic impedance limit use to low-current biasing, not power rail clamping | Choose only for space-constrained PCBs where MELF footprint is unacceptable and regulation stability is secondary |
Compared with 1N6016UR-1/TR and BZX84-C47LT1G, the 1N6016BUR-1/TR delivers superior thermal performance (300 °C/W), lower dynamic impedance (11 Ω), and direct MIL-PRF-19500 qualification path - making it the preferred choice for high-reliability 47 V reference and clamp functions.

Is 1N6016BUR-1/TR RoHS compliant?
Yes, the 1N6016BUR-1/TR is RoHS compliant (e3 suffix), as stated in the "PART NOMENCLATURE" section on page 2 of T4-LDS-0228-1 Rev. 1. RoHS compliance applies to commercial-grade versions only; military-screened variants (MQ/MX/MV/CDS) retain leaded terminations per specification.
What package type does 1N6016BUR-1/TR use?
The 1N6016BUR-1/TR uses the DO-213AA package - also known as SOD80 or MELF - a hermetically sealed glass cylindrical surface-mount package with metallurgically bonded end caps. Dimensions and pad layout are provided on page 5 of T4-LDS-0228-1 Rev. 1.
Can 1N6016BUR-1/TR be used in aerospace applications?
Yes, the 1N6016BUR-1/TR serves as the commercial baseline for aerospace-qualified versions: adding MQ (JAN), MX (JANTX), MV (JANTXV), or CDS (JANS) prefixes yields MIL-PRF-19500 screened equivalents. Radiation hardness is documented in MicroNote 050, supporting use in satellite and avionics systems.
What is the maximum Zener current (IZM) for 1N6016BUR-1/TR?
The maximum dc Zener current (IZM) for 1N6016BUR-1/TR is 200 mA, as listed in the Electrical Characteristics table on page 3 of T4-LDS-0228-1 Rev. 1. This value corresponds to the nominal 47 V rating and 0.5 W power dissipation limit at 25 °C ambient.
