Product details
Overview
1N6017BUR-1/TR from Microsemi is a surface-mount 51 V, 2 mA test-current Zener diode in DO-213AA (MLL34/SOD80) MELF glass package, rated for 500 mW power dissipation at 25°C, with ±5% voltage tolerance (B suffix), and designed for precision voltage regulation in space-constrained industrial and aerospace power supplies.
For engineers reviewing the 1N6017BUR-1/TR datasheet, 1N6017BUR-1/TR pinout, 1N6017BUR-1/TR application, or 1N6017BUR-1/TR equivalent, key selection criteria include its 51 V nominal Zener voltage at 2 mA, 9.8 mA maximum DC Zener current, 180 Ω dynamic impedance at IZT, low 0.1 µA reverse leakage at 39 V, and radiation-hardened hermetic glass construction per MIL-PRF-19500 screening options.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown to maintain stable output voltage across wide current (0.25–9.8 mA) and temperature (−65°C to +175°C) ranges. Its DO-213AA package features metallurgically bonded end caps and RoHS-compliant matte-tin plating for reliable solderability.
It exhibits a positive temperature coefficient of +0.096 %/°C and typical capacitance under 10 pF, enabling use in low-noise analog references and ESD-insensitive bias networks where minimal parasitic capacitance and high reliability are required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage (VZ) | 51 V at 2 mA test current - defines regulated output voltage under standard bias condition |
| Power Dissipation (PD) | 0.5 W at 25°C ambient - limits continuous thermal load on PCB without derating |
| Zener Impedance (ZZT) | 180 Ω at 2 mA - determines regulation stiffness and AC ripple rejection capability |
| Reverse Leakage Current (IR) | 0.1 µA at 39 V - ensures minimal standby power loss in high-impedance bias networks |
| Max DC Zener Current (IZM) | 9.8 mA - sets absolute upper current limit before thermal runaway risk |
| Temp. Coefficient (αVZ) | +0.096 %/°C - quantifies voltage drift over temperature for stability-critical references |
| Junction Temp. Range | −65°C to +175°C - supports operation in extended industrial, avionics, and downhole environments |
Pinout & Package
DO-213AA (SOD80 / MLL34) MELF glass package: hermetically sealed cylindrical body with tin-lead or RoHS matte-tin plated end caps; cathode indicated by single band; polarity: banded end is anode when used as forward diode, but cathode when operated in Zener regulation mode (banded end negative for reverse-bias regulation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Forward conduction terminal / Zener regulation return path | Connected to lower-potential node in shunt regulator; carries full load current during regulation |
| Cathode (banded end) | Zener breakdown terminal / reference node | Connected to higher-potential node; establishes stable 51 V reference relative to anode |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass MELF construction | Enables operation up to +175°C junction temperature and inherent radiation hardness per MicroNote 050 |
| MIL-PRF-19500 screening compatibility | Supports JAN, JANTX, JANTXV, and JANS variants via prefix addition for aerospace/military qualification |
| Low 0.1 µA reverse leakage at 39 V | Minimizes quiescent current draw in battery-backed or ultra-low-power bias circuits |
| 10% tolerance option available (A suffix) | Provides cost-optimized alternative for non-critical voltage reference applications |
| RoHS-compliant matte-tin plating | Ensures lead-free assembly compatibility while maintaining MIL-STD-750 solderability |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6017B-1 | Axial DO-35 package; identical electrical specs but larger footprint and lower thermal resistance (RθJA = 500°C/W vs. 300°C/W) | Suitable for through-hole prototyping or legacy board rework where SMT is not feasible | Select 1N6017B-1 only when manual assembly or socketing is required; avoid for high-density or automated production. |
| BZX55-C51 | Pro Electron series; same 51 V/5% rating but plastic DO-35 package, higher leakage (5 µA @ 39 V), and no MIL-PRF-19500 screening path | Cost-sensitive commercial instrumentation where radiation hardness and extreme temp range are unnecessary | Choose BZX55-C51 for consumer-grade designs with budget constraints; reject for aerospace or high-reliability systems. |
Compared with 1N6017B-1 and BZX55-C51, the 1N6017BUR-1/TR offers superior thermal performance in SMT layouts, guaranteed hermetic reliability, and direct military qualification path-making it the sole choice for space-constrained, high-stability, or mission-critical voltage references.

FAQ
What is the Zener voltage tolerance for 1N6017BUR-1/TR?
The "B" suffix in 1N6017BUR-1/TR denotes a ±5% Zener voltage tolerance, meaning its actual breakdown voltage falls between 48.45 V and 53.55 V at the 2 mA test current. This tolerance is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0228-1 Rev. 1, and applies specifically to the 1N6017BUR-1/TR variant-not to other suffixes like "A" (±10%) or "C" (±2%).
Does 1N6017BUR-1/TR support RoHS compliance?
Yes, the "e3" RoHS-compliant matte-tin plating is available for the commercial-grade 1N6017BUR-1/TR, as stated in the Part Nomenclature section on page 2 of T4-LDS-0228-1 Rev. 1. Non-RoHS versions (tin-lead plating) are also offered, but the e3 designation must appear in the full part number (e.g., 1N6017BUR-1/TR e3) to guarantee compliance.
What is the maximum allowable Zener current for 1N6017BUR-1/TR?
The maximum DC Zener current (IZM) for 1N6017BUR-1/TR is 9.8 mA, derived from its 51 V nominal voltage and 0.5 W power rating using the formula IZM = PD/VZM, where VZM = 51 V × 1.05 = 53.55 V. This value is explicitly listed in the Electrical Characteristics table on page 3 of T4-LDS-0228-1 Rev. 1 for the 1N6017BUR series.
Can 1N6017BUR-1/TR be used in high-temperature environments?
Yes, 1N6017BUR-1/TR is rated for junction temperatures from −65°C to +175°C and has been validated for operation at +150°C ambient in downhole applications. Its hermetic DO-213AA glass package and metallurgical bonding ensure stability where plastic-packaged Zeners would degrade, as documented in Microsemi's MicroNote 050 on radiation hardness and thermal endurance.
Is there a military-qualified version of 1N6017BUR-1/TR?
Yes-military screening per MIL-PRF-19500 is available by adding a prefix: MQ for JAN, MX for JANTX, MV for JANTXV, or CDS for JANS. For example, MQ1N6017BUR-1/TR meets Level 1 reliability requirements. This option is detailed in the Part Nomenclature section on page 2 of T4-LDS-0228-1 Rev. 1 and applies identically to the 1N6017BUR-1/TR base design.
