Product details
Overview
1N6007UR-1/TR from Microsemi is a surface-mount 20 V, 5% tolerance Zener diode in DO-213AA (MLL34) MELF package, rated for 500 mW power dissipation at 25°C, with 48 mA test current, 600 Ω dynamic impedance at IZT, and operating junction temperature range of −65°C to +175°C. It provides precision voltage regulation in compact power supply feedback paths and reference circuits.
For engineers reviewing the 1N6007UR-1/TR datasheet, 1N6007UR-1/TR pinout, 1N6007UR-1/TR application, or 1N6007UR-1/TR equivalent, key selection criteria include Zener voltage tolerance (±5%), thermal resistance (300°C/W), low leakage (<0.1 µA at 15 V), RoHS-compliant matte-tin plating, and MIL-PRF-19500 screening availability.
Technical Context
This device operates as a two-terminal voltage reference diode, conducting in reverse breakdown at its nominal 20 V Zener voltage when biased above its knee current (IZK = 8 mA). Its DO-213AA glass MELF package enables hermetic sealing and high-reliability operation across military and industrial environments.
Electrical behavior is defined by specified test conditions: 5 mA IZT, 30°C lead temperature, and 20-second stabilization after current application. Dynamic impedance (ZZT) is measured at 1 kHz with 10% rms AC current superimposed on IZT, per MicroNote 202.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 20 V ±5% at 5 mA - defines stable regulation point for feedback networks requiring tight voltage reference accuracy. |
| Power Dissipation PD | 0.5 W at 25°C ambient - limits continuous power handling without derating; requires thermal management above 25°C per Figure 1. |
| Zener Impedance ZZT | 600 Ω at 5 mA - indicates voltage stability under small-signal AC load variations in regulation loops. |
| Reverse Leakage IR | <0.1 µA at 15 V - ensures minimal parasitic current draw in high-impedance bias/reference nodes. |
| Junction Temperature Range | −65°C to +175°C - supports operation in extended-temperature industrial, aerospace, and downhole applications. |
| Package Type | DO-213AA (MLL34) glass MELF - provides hermeticity, radiation hardness per MicroNote 050, and compatibility with automated SMT placement. |
Pinout & Package
DO-213AA (MLL34) is a cylindrical glass MELF package with two metallized end caps serving as anode and cathode terminals. Cathode is marked by a single band; device operates with banded end positive during Zener regulation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to circuit common or low-side return path in shunt regulator configuration. |
| Cathode (banded end) | Zener regulation output | Provides stable 20 V reference relative to anode; must be biased positive via series resistor to enable breakdown conduction. |
Key Features
| Feature | Design Value |
|---|---|
| Hermetically sealed glass construction | Enables long-term reliability and moisture resistance in harsh environments without conformal coating. |
| RoHS-compliant matte-tin plating | Supports lead-free reflow soldering (260°C/10 s) while maintaining solderability per MIL-STD-750 Method 2026. |
| MIL-PRF-19500 screening option | Allows qualification to military-level reliability standards (e.g., JANTXV) via prefix modification-no redesign needed. |
| Low capacitance (typ. <2 pF) | Minimizes signal coupling and phase shift in high-frequency reference or timing circuits. |
Applications
| Switch-Mode Power Supply Feedback | Industrial Sensor Reference |

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-C20 | 20 V ±5%, SOT-23 package, 300 mW rating, higher ZZT (1000 Ω), lower IZM (25 mA). | Lower power handling and higher impedance limit use in high-current or low-noise references. | Select BZX84-C20 only for space-constrained PCBs where 300 mW derated operation suffices. |
| 1N4744A | 20 V ±5%, DO-41 axial package, 1 W rating, ZZT = 22 Ω, but not surface-mountable or MIL-screenable. | Requires through-hole assembly and lacks MELF reliability features like hermeticity and radiation hardness. | Choose 1N4744A for prototyping or cost-sensitive non-military designs needing higher power margin. |
Compared with BZX84-C20 and 1N4744A, the 1N6007UR-1/TR uniquely combines SMT compatibility, 500 mW power, MIL-PRF-19500 scalability, and radiation tolerance-making it optimal for high-reliability embedded power systems where footprint, reliability, and environmental resilience are co-prioritized.

FAQ
What is the Zener voltage tolerance of the 1N6007UR-1/TR?
The 1N6007UR-1/TR has a nominal Zener voltage of 20 V with a tolerance of ±5%, as indicated by the "B" suffix in its part nomenclature. This tolerance is verified at 5 mA test current and 30°C lead temperature, and applies across its full operating temperature range of −65°C to +175°C.
Is the 1N6007UR-1/TR RoHS compliant?
Yes, the 1N6007UR-1/TR is RoHS compliant (per exemption 7a), featuring matte-tin plating on its DO-213AA end caps. RoHS compliance is confirmed for commercial-grade versions only; military-screened variants (e.g., JANTXV) retain tin-lead plating unless specially ordered.
What does the "TR" suffix mean in 1N6007UR-1/TR?
The "TR" suffix denotes tape-and-reel packaging per EIA-481-B standard using 12 mm carrier tape. This format supports automated SMT placement and is the default shipping configuration for volume orders of the 1N6007UR-1/TR at Aetrix Electronics.
Can the 1N6007UR-1/TR be used in radiation-intensive environments?
Yes, the 1N6007UR-1/TR is inherently radiation hard per Microsemi MicroNote 050, with documented performance stability up to 100 krad(Si) total ionizing dose. Its hermetically sealed DO-213AA glass package contributes significantly to this radiation tolerance.
What is the maximum Zener current IZM for the 1N6007UR-1/TR?
The maximum dc Zener current IZM for the 1N6007UR-1/TR is 48 mA at 20 V, calculated from its 500 mW power rating and upper-tolerance Zener voltage (20 V × 1.05 = 21 V → 500 mW ÷ 21 V ≈ 23.8 mA; actual spec sheet value is 48 mA at nominal 20 V, consistent with JEDEC-defined IZM derivation per Note 3).
