Product details
Overview
1N6007UR/TR from Microsemi is a surface-mount 20 V Zener diode in DO-213AA (SOD-80) MELF package, rated for 500 mW power dissipation at 25°C, with ±5% voltage tolerance (B-suffix), 48 mA test current (IZT), and 600 Ω dynamic impedance (ZZT) - used for precision voltage regulation in power supply feedback loops and reference circuits.
For engineers reviewing the 1N6007UR/TR datasheet, 1N6007UR/TR pinout, 1N6007UR/TR application, or 1N6007UR/TR equivalent, key selection criteria include Zener voltage accuracy, thermal resistance (RθJA = 300°C/W), low leakage (<0.1 µA at 16 V), radiation-hardened construction, and RoHS-compliant matte-tin plating for reflow soldering compatibility.
Technical Context
This device operates as a two-terminal voltage reference in reverse-biased breakdown mode, with regulation established at IZT = 48 mA and VZ = 20.0 V. Its DO-213AA glass MELF package provides hermetic sealing and inherent radiation hardness per MicroNote 050.
It exhibits a positive temperature coefficient of +0.085%/°C and maintains stable regulation across -65°C to +175°C junction temperature range. Reverse leakage remains ≤0.1 µA at 16 V, and forward voltage is ≤1.1 V at 200 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 20.0 V at 48 mA - defines precise regulation point for feedback networks and voltage references. |
| Power Dissipation (PD) | 0.5 W at 25°C ambient - sets maximum continuous power handling on FR4 board with standard footprint. |
| Zener Impedance (ZZT) | 600 Ω at 48 mA - indicates regulation stiffness; lower values improve load/line transient response. |
| Reverse Leakage (IR) | ≤0.1 µA at 16 V - ensures minimal error current in high-impedance reference paths. |
| Temp. Coefficient (αVZ) | +0.085 %/°C - enables predictable drift compensation in temperature-critical references. |
| Junction Temp. Range | -65°C to +175°C - supports operation in aerospace, industrial, and downhole environments. |
| Package | DO-213AA (SOD-80) MELF - glass-encapsulated, hermetically sealed, RoHS-compliant matte-tin end caps. |
Pinout & Package
DO-213AA (SOD-80) MELF package: cylindrical glass body with metallized end caps; cathode indicated by single black band; no polarity-specific PCB pad asymmetry - symmetric footprint required.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to circuit common; must sink full Zener current during regulation. |
| Cathode (banded end) | Regulated output node | Provides stable 20 V when reverse-biased; polarity critical for correct regulation direction. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetic glass MELF construction | Enables operation in high-reliability, radiation-intensive environments per MicroNote 050. |
| RoHS-compliant matte-tin plating | Supports lead-free reflow soldering (260°C, 10 s) without intermetallic degradation. |
| Low capacitance (typ. <2 pF) | Minimizes signal coupling and noise injection in RF-adjacent or high-speed control circuits. |
| MIL-PRF-19500 screening option | Available with MQ/MX/MV/CDS prefixes for defense/aerospace applications requiring extended reliability testing. |
| ESD immunity (MIL-STD-750, Method 1020) | Eliminates need for external ESD protection in handling and assembly of sensitive systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BZX55-C20 | Same 20 V nominal, ±5% tolerance, but DO-35 axial package; RθJA = 500°C/W; non-RoHS default. | Limited to through-hole assembly; higher thermal resistance restricts power handling in compact layouts. | Select BZX55-C20 only when legacy axial footprint or cost-driven prototyping is required. |
| MMBZ5248B | SOT-23 package; 20 V, ±5%; PD = 350 mW; RθJA = 350°C/W; higher leakage (≤1 µA at 16 V). | Surface-mount compatible but lower power rating and less stable tempco (+0.09%/°C). | Choose MMBZ5248B only for space-constrained boards where 0.35 W dissipation suffices and leakage tolerance >0.1 µA is acceptable. |
Compared with BZX55-C20 and MMBZ5248B, the 1N6007UR/TR delivers superior thermal performance (RθJA = 300°C/W), lower leakage, and radiation-hardened reliability - making it optimal for high-stability, high-reliability surface-mount regulation where 0.5 W power handling and hermetic integrity are essential.

FAQ
What is the Zener voltage tolerance of the 1N6007UR/TR?
The 1N6007UR/TR has a nominal Zener voltage of 20.0 V with ±5% tolerance (B-suffix), meaning its actual VZ falls between 19.0 V and 21.0 V when measured at 48 mA test current and 30°C lead temperature. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi T4-LDS-0228-1 Rev. 1.
Does the 1N6007UR/TR support lead-free reflow soldering?
Yes, the 1N6007UR/TR features RoHS-compliant matte-tin plating on its end caps and is qualified for lead-free reflow soldering at 260°C for 10 seconds, as specified in the Maximum Ratings table. The "e3" RoHS designation applies to commercial-grade units, and the TR suffix confirms tape-and-reel packaging compatible with automated placement.
What is the maximum reverse leakage current for the 1N6007UR/TR?
The 1N6007UR/TR has a maximum reverse leakage current (IR) of 0.1 µA at 16 V, as stated in the Electrical Characteristics table. This ultra-low leakage ensures minimal error contribution in high-impedance reference circuits and precision analog signal paths where current draw must be tightly controlled.
Can the 1N6007UR/TR be used in radiation-intensive environments?
Yes, the 1N6007UR/TR is inherently radiation-hardened due to its hermetically sealed glass DO-213AA package and internal metallurgical bonds, as documented in Microsemi MicroNote 050. It is widely deployed in aerospace and defense systems where total ionizing dose (TID) resilience is required without additional shielding.
What is the thermal resistance from junction to ambient for the 1N6007UR/TR?
The 1N6007UR/TR has a thermal resistance of RθJA = 300°C/W when mounted on an FR4 printed circuit board with 1 oz copper and the recommended footprint, per the Maximum Ratings table. This value governs derating above 25°C ambient and must be applied to maintain safe junction temperatures below +175°C.
