Product details
Overview
1N6004UR/TR from Microsemi is a surface-mount 15 V, 5% tolerance Zener diode in DO-213AA (SOD80) MELF package, rated for 500 mW power dissipation at 25°C, with 32 mA test current (IZT), 600 Ω dynamic impedance (ZZT), and ±0.079%/°C temperature coefficient - used for precision voltage regulation in power supply feedback loops and reference circuits.
For engineers reviewing the 1N6004UR/TR datasheet, 1N6004UR/TR pinout, 1N6004UR/TR application, or 1N6004UR/TR equivalent, this page delivers verified electrical parameters, package dimensions, thermal derating behavior, RoHS-compliant plating details, and validated alternative parts for stable voltage reference design.
Technical Context
This device operates as a two-terminal voltage regulator in reverse-biased breakdown mode, with Zener voltage specified at 15 V ±5% (14.25–15.75 V) under 5 mA test current per JEDEC standard. Its DO-213AA glass MELF construction provides hermetic sealing and inherent radiation hardness per MicroNote 050.
Thermal resistance junction-to-ambient is 300°C/W on FR4 board with recommended footprint; derating begins above 25°C ambient, reaching zero power at 125°C. Reverse leakage is limited to 0.1 µA at 11.3 V, and forward voltage is 1.1 V at 200 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 15 V ±5% at 5 mA IZT - defines nominal regulation point with tight tolerance for stable reference generation |
| Power Dissipation | 0.5 W at 25°C ambient - sets maximum continuous power handling before thermal derating applies |
| Zener Impedance (ZZT) | 600 Ω at 5 mA - indicates regulation stiffness; lower values yield tighter output voltage control under load variation |
| Reverse Leakage (IR) | 0.1 µA at 11.3 V - ensures minimal error current in high-impedance reference paths |
| Temp. Coefficient (αVZ) | +0.079 %/°C - quantifies voltage drift with temperature; positive sign means VZ increases with heat |
| Package | DO-213AA (SOD80/MELF) - glass-encapsulated cylindrical surface-mount package with end-cap terminations |
| RoHS Compliance | e3 suffix = matte-tin plating (commercial grade only) - meets lead-free soldering requirements without SnPb |
Pinout & Package
DO-213AA (SOD80) is a hermetically sealed glass MELF package with two metallized end caps serving as anode and cathode terminals. Cathode is marked by a single black band; polarity must be observed for proper Zener operation (cathode positive relative to anode).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Cathode (banded end) | Zener regulation terminal | Connected to higher potential node; reverse bias enables breakdown conduction at VZ |
| Anode (unbanded end) | Reference/return terminal | Connected to circuit ground or lower potential; completes Zener current path during regulation |
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 |
| Internal metallurgical bonds | Ensures mechanical robustness and long-term reliability under thermal cycling and vibration stress |
| Radiation-hardened design | Validated per Microsemi MicroNote 050 - suitable for space-qualified and high-reliability systems |
| Low capacitance | Typical <1 pF (per Figure 2) - minimizes signal coupling and noise in high-frequency reference applications |
| ESD insensitivity | Passes MIL-STD-750 Method 1020 - eliminates need for external ESD protection in handling and assembly |
Applications
| Switch-Mode Power Supply Feedback | Industrial Sensor Reference |
|---|---|
Use Scenario: Provides stable 15 V reference for optocoupler-based feedback in isolated DC-DC converters. IC Role / Device Role / Timing Role: Zener voltage reference enabling precise output voltage regulation via error amplifier comparison.

IC Role / Device Role / Timing Role: Precision analog reference source for ratiometric sensor signal conditioning. Use Value: Low IR (<0.1 µA) prevents loading of high-impedance sensor outputs and maintains measurement linearity. |
| Programmable Logic Controller Input Protection | Aerospace Power Monitor Calibration |
Use Scenario: Clamps transient overvoltage on 24 V digital input channels to protect FPGA I/O pins. IC Role / Device Role / Timing Role: Overvoltage suppression element limiting input voltage to safe Zener breakdown level. Use Value: Fast response and non-sensitive ESD behavior eliminate need for additional TVS staging in ruggedized PLC designs. |

IC Role / Device Role / Timing Role: Radiation-hardened voltage standard used in calibration fixtures for flight hardware testing. Use Value: Inherent radiation hardness per MicroNote 050 avoids costly qualification testing for space-grade use. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6004UR-1 | No tape-and-reel packaging; bulk or ammo-pack only; identical electrical specs and DO-213AA package | Suitable for manual prototyping or low-volume hand-soldered assemblies where reel feeding is unnecessary | Select 1N6004UR/TR when automated SMT placement is required; choose 1N6004UR-1 for bench evaluation or small-batch builds |
| BZX55-C15 | DO-35 axial package; 5% tolerance; 500 mW rating; slightly higher ZZT (700 Ω) and different thermal resistance profile | Preferred for through-hole legacy designs or where board space allows axial components and manual rework is routine | Choose BZX55-C15 only if DO-35 footprint exists; otherwise 1N6004UR/TR offers superior thermal performance in SMT layouts |
Compared with 1N6004UR-1 and BZX55-C15, the 1N6004UR/TR delivers identical regulation performance in a surface-mount MELF package optimized for automated assembly, thermal efficiency on FR4, and radiation-hardened reliability - making it the preferred choice for modern industrial and aerospace SMT power management.
