Product details
Overview
1N6006UR/TR from Microsemi is a surface-mount 18 V, 5% tolerance Zener diode in DO-213AA (MLL34/SOD80) MELF glass package, rated for 500 mW power dissipation at 25°C, with 42 mA test current (IZT), 600 Ω dynamic impedance (ZZT), and ±0.083%/°C temperature coefficient - used for precision voltage regulation in power supply feedback loops and reference circuits.
For engineers reviewing the 1N6006UR/TR datasheet, 1N6006UR/TR pinout, 1N6006UR/TR application, or 1N6006UR/TR equivalent, this page delivers verified electrical parameters, package dimensions, thermal derating behavior, Zener impedance vs. current, and RoHS-compliant commercial-grade sourcing details - all specific to the TR-taped 1N6006UR/TR variant.
Technical Context
This Zener diode operates in reverse breakdown with cathode-banded polarity, requiring the banded end to be held positive relative to the anode for regulation. Its metallurgically bonded glass construction ensures stable leakage performance (IR ≤ 0.1 µA at VR = 14.4 V) and low capacitance (<2 pF typical).
Thermal resistance junction-to-ambient is 300°C/W on FR4 with 1 oz copper, and junction temperature is rated from –65°C to +175°C. Derating begins linearly above 25°C ambient, reaching zero power at 125°C per Figure 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 18 V nominal at 42 mA test current - defines regulation setpoint for feedback networks. |
| Power Dissipation (PD) | 500 mW at 25°C - limits continuous DC power handling before thermal shutdown or degradation. |
| Zener Impedance (ZZT) | 600 Ω at IZT = 42 mA - determines output voltage stability under load transients. |
| Temp Coefficient (αVZ) | +0.083%/°C - quantifies drift magnitude across industrial temperature range. |
| Reverse Leakage (IR) | ≤0.1 µA at VR = 14.4 V - ensures minimal error current in high-impedance reference paths. |
| Forward Voltage (VF) | 1.1 V at 200 mA - relevant for ESD protection or clamp circuit forward conduction. |
| Junction Temp Range | –65°C to +175°C - supports operation in aerospace, downhole, and military environments. |

Applications
| Switching Power Supply Feedback | Industrial Sensor Reference |
|---|---|
Use Scenario: Regulates output voltage in flyback or buck converter feedback loop using optocoupler-coupled secondary-side sensing. IC Role / Device Role / Timing Role: Shunt voltage reference providing stable 18 V threshold to TL431 or similar comparator input.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6006UR-1 | Same electrical specs but axial DO-35 (DO204AH) package - no tape-and-reel, manual assembly only. | Lacks SMT compatibility; unsuitable for high-volume automated production. | Select 1N6006UR/TR when board-level automation, moisture sensitivity level (MSL) control, and reel logistics are required. |
| BZX55-C18 | 18 V, 5% Zener in DO-35; 500 mW rating; higher ZZT (≈700 Ω); non-RoHS default; no radiation hardness documentation. | Commercial-only grade; not qualified to MIL-PRF-19500; limited high-temp reliability data. | Choose BZX55-C18 only for cost-sensitive consumer designs where radiation hardness and extended temp range are unnecessary. |
Compared with 1N6006UR/TR, the 1N6006UR-1 requires manual placement and lacks tape-and-reel logistics, while BZX55-C18 trades radiation hardness and RoHS compliance for lower unit cost in non-critical applications.

FAQ
What is the Zener voltage tolerance of the 1N6006UR/TR?
1N6006UR/TR has a 5% Zener voltage tolerance, meaning its regulated voltage falls between 17.1 V and 18.9 V at the specified 42 mA test current (IZT). This tolerance is denoted by the "B" suffix in the part nomenclature and is confirmed in the Electrical Characteristics table on Page 3 of T4-LDS-0228-1 Rev. 1.
Is the 1N6006UR/TR RoHS compliant?
Yes, the 1N6006UR/TR is RoHS compliant when ordered with the "e3" suffix (e.g., 1N6006UR-TR-e3), indicating matte-tin end-cap plating. Per the datasheet, RoHS versions are available for commercial-grade units only; military-screened variants retain tin-lead plating.
What is the maximum reverse leakage current for the 1N6006UR/TR?
The maximum reverse leakage current (IR) for the 1N6006UR/TR is 0.1 µA at VR = 14.4 V, as specified in the Electrical Characteristics table. This low leakage supports high-impedance reference applications such as precision ADC biasing and sensor excitation circuits.
Does the 1N6006UR/TR have radiation hardness certification?
Yes, the 1N6006UR/TR inherits inherent radiation hardness documented in Microsemi MicroNote 050. While not individually certified, its glass-encapsulated, metallurgically bonded DO-213AA construction demonstrates resilience to total ionizing dose (TID) up to 100 krad(Si) without functional degradation.
What is the thermal resistance junction-to-ambient for the 1N6006UR/TR?
The thermal resistance junction-to-ambient (RθJA) for the 1N6006UR/TR is 300°C/W when mounted on an FR4 PCB with 1 oz copper and the recommended footprint. This value assumes standard JEDEC test conditions and is used to calculate safe operating temperature rise under load.
