Product details
Overview
1N6014UR-1/TR from Microsemi is a surface-mount 39 V, 5% tolerance Zener diode in DO-213AA (MLL34) glass MELF package, rated for 500 mW power dissipation at 25°C, with 2.0 mA test current, 130 Ω dynamic impedance, and ±0.095%/°C temperature coefficient - used for precision voltage regulation in power supply feedback loops and reference circuits.
For engineers reviewing the 1N6014UR-1/TR datasheet, 1N6014UR-1/TR pinout, 1N6014UR-1/TR application, or 1N6014UR-1/TR equivalent, key selection criteria include Zener voltage tolerance, thermal resistance (300°C/W junction-to-ambient), low leakage (<0.1 µA at 31.2 V), RoHS-compliant matte-tin plating, and tape-and-reel packaging for automated assembly.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable voltage across wide current (0.25–130 mA) and temperature (−65°C to +175°C) ranges. Its DO-213AA glass package provides hermetic sealing and inherent radiation hardness per MicroNote 050.
Regulation performance relies on metallurgically bonded construction, low capacitance (typical 13 pF), and tight 5% voltage tolerance at IZT = 2.0 mA - enabling use in analog references where drift and noise must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Zener Voltage | 39 V at 2.0 mA test current - defines regulation setpoint for feedback networks. |
| Zener Tolerance | ±5% - ensures output voltage remains within 37.05–40.95 V under production variation. |
| Power Dissipation | 0.5 W at 25°C ambient - limits continuous thermal load on PCB without heatsinking. |
| Dynamic Impedance | 130 Ω at 2.0 mA - determines output voltage change per mA of load current shift. |
| Temp. Coefficient | +0.095%/°C - quantifies voltage drift with temperature; critical for high-stability references. |
| Reverse Leakage | <0.1 µA at 31.2 V - ensures minimal error current in high-impedance bias networks. |
| Junction Temp. Range | −65°C to +175°C - supports operation in extended industrial and aerospace environments. |
Pinout & Package
DO-213AA (MLL34) glass MELF package: hermetically sealed cylindrical body with tin-lead or RoHS-compliant matte-tin end-cap plating; cathode indicated by single band; polarity: banded end is cathode (positive during Zener operation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Zener anode connection point | Connected to regulated output node; reverse-biased to conduct and clamp voltage. |
| Anode (unbanded end) | Zener cathode connection point | Connected to ground or lower-potential rail; completes reverse-bias path for regulation. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass MELF construction | Enables long-term reliability and moisture resistance without conformal coating. |
| Metallurgical bonding | Reduces thermal interface resistance and improves power cycling endurance. |
| Radiation-hardened design | Validated per MicroNote 050 for total ionizing dose tolerance in space applications. |
| Low capacitance (13 pF typical) | Minimizes signal coupling and phase shift in high-frequency feedback paths. |
| ESD-insensitive (MIL-STD-750 Method 1020) | Eliminates need for handling precautions during SMT assembly and board testing. |

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-C39 | 300 mW SOT-23 package; 10% tolerance; higher ZZT (150 Ω); no radiation hardening. | Lower power density; unsuitable for high-reliability aerospace or extended-temp industrial use. | Select when cost-sensitive consumer designs require SMT compatibility but not hermeticity or radiation tolerance. |
| 1N4739A | 1 W DO-41 axial package; 5% tolerance; 100 Ω ZZT; −65°C to +175°C rating; non-RoHS default. | Larger footprint; requires through-hole assembly; higher power headroom but no tape-and-reel option. | Select when board space allows axial mounting and >500 mW derated power is required at elevated temperatures. |
