Product details
Overview
1N6008UR-1/TR from Microsemi is a surface-mount 22 V, 5% tolerance Zener diode in DO-213AA (SOD-80/MELF) package, rated for 500 mW power dissipation at 25°C, with 5 mA test current, 70 Ω dynamic impedance at IZT, and ±0.087%/°C temperature coefficient - used for precision voltage regulation in low-power analog reference and overvoltage protection circuits.
For engineers reviewing the 1N6008UR-1/TR datasheet, 1N6008UR-1/TR pinout, 1N6008UR-1/TR application, or 1N6008UR-1/TR equivalent, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (300°C/W), junction temperature range (–65°C to +175°C), RoHS compliance status, and MELF package compatibility with automated SMT assembly.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown at precisely 22 V when biased above its knee current (IZK = 0.25 mA). Its metallurgically bonded glass construction ensures stable Zener characteristics across wide temperature excursions and high reliability under thermal cycling.
The DO-213AA package enables low parasitic capacitance (<15 pF typical at 22 V) and minimal leakage (≤0.1 µA at 17 V), supporting stable regulation in noise-sensitive analog signal chains and low-current bias networks where voltage drift must remain below ±0.1%/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 22 V ±5% at 5 mA - defines nominal regulation point with tight tolerance for stable reference generation. |
| Power Dissipation PD | 0.5 W at 25°C ambient - sets maximum continuous power handling on FR4 board with 1 oz Cu. |
| Zener Impedance ZZT | 70 Ω at 5 mA - determines output voltage variation under load current changes; critical for ripple rejection. |
| Temp. Coefficient αVZ | +0.087 %/°C - quantifies voltage drift per degree; enables accurate thermal error budgeting in precision designs. |
| Reverse Leakage IR | ≤0.1 µA at 17 V - ensures minimal shunt current in standby mode, preserving battery life in low-power systems. |
| Junction Temp. Range | –65°C to +175°C - supports operation in harsh environments including automotive under-hood and industrial control cabinets. |
| Package Type | DO-213AA (SOD-80/MELF) - hermetically sealed glass cylindrical package optimized for SMT reflow and high-reliability screening. |
Pinout & Package
DO-213AA (SOD-80/MELF) is a two-terminal glass-encapsulated cylindrical package with tin-lead or matte-tin end-cap plating; cathode indicated by single black band; polarity: banded end is cathode (positive during Zener conduction).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference node | Connected to circuit ground or lower-potential rail; forms reference return path during regulation. |
| Cathode | Zener regulation terminal / voltage reference output | Banded end; connected to regulated voltage node; supplies stable 22 V to load when reverse-biased above breakdown. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N6008B-1/TR | Same 22 V nominal voltage but ±1% tolerance (D-suffix); tighter regulation at cost of higher unit price. | Suitable for metrology-grade references where ±0.22 V absolute accuracy is required vs. ±1.1 V for 1N6008UR-1/TR. | Select 1N6008B-1/TR only if system-level calibration budget requires sub-1% voltage error across temperature. |
| BZX84-C22LT1G | SOT-23 package (vs. DO-213AA); 22 V ±5%, 300 mW rating; higher thermal resistance (450°C/W vs. 300°C/W). | Preferred for space-constrained PCBs but unsuitable for >70°C ambient without derating; lacks MIL-PRF-19500 screening path. | Choose BZX84-C22LT1G only when footprint reduction outweighs thermal performance and reliability requirements. |
Compared with 1N6008B-1/TR and BZX84-C22LT1G, the 1N6008UR-1/TR delivers optimal balance of cost, thermal robustness (300°C/W), and qualification readiness - making it preferred for industrial and automotive modules requiring extended temperature operation without premium tolerance cost.

FAQ
What is the Zener voltage tolerance of the 1N6008UR-1/TR?
The 1N6008UR-1/TR has a nominal Zener voltage of 22 V with a ±5% tolerance (B-suffix), meaning its actual regulation voltage falls between 20.9 V and 23.1 V at 5 mA test current and 30°C lead temperature. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0228-1 datasheet.
Is the 1N6008UR-1/TR RoHS compliant?
Yes, the 1N6008UR-1/TR is RoHS compliant (e3 suffix), featuring matte-tin end-cap plating per EU Directive 2011/65/EU. RoHS compliance applies only to commercial-grade versions; military-screened variants (e.g., MX/ MV prefixes) retain tin-lead plating unless otherwise specified.
What is the maximum Zener current IZM for the 1N6008UR-1/TR?
The maximum dc Zener current IZM for the 1N6008UR-1/TR is 70 mA at 22 V nominal voltage, calculated from PD = 0.5 W and VZM = 23.1 V (upper limit of ±5% tolerance). This value is derived using the formula IZM = P / VZM as stated in Note 3 on page 4 of the datasheet.
Does the 1N6008UR-1/TR have a defined forward voltage specification?
Yes, the 1N6008UR-1/TR specifies a maximum forward voltage VF of 1.1 V at 200 mA forward current, per the Maximum Ratings table on page 1. This parameter is relevant for applications involving bidirectional clamping or forward-conduction testing during functional verification.
Can the 1N6008UR-1/TR be used in high-reliability aerospace applications?
The 1N6008UR-1/TR itself is a commercial-grade part, but Microsemi offers screened equivalents meeting MIL-PRF-19500 requirements by adding prefix identifiers (e.g., MX1N6008UR-1/TR for JANTX level). These variants undergo additional environmental and electrical testing to qualify for aerospace use.
