Product details
Overview
1N4113DUR-1/TR from Microsemi is a 19.0 V, 1% tolerance, 500 mW surface-mount Zener diode in DO-213AA (SOD-80) glass MELF package, metallurgically bonded for high-reliability voltage regulation in precision reference and power supply circuits across aerospace, defense, and industrial systems.
For engineers reviewing the 1N4113DUR-1/TR datasheet, 1N4113DUR-1/TR pinout, 1N4113DUR-1/TR application, or 1N4113DUR-1/TR equivalent, this part delivers low-noise (1 µV/√Hz), stable temperature coefficient (+0.090 %/°C), and MIL-PRF-19500/435 qualification up to JANS level - critical for radiation-hardened, hermetically sealed, and ESD-insensitive designs.
Technical Context
This Zener diode operates in reverse breakdown with a nominal test current of 250 mA and exhibits dynamic impedance of 150 Ω at IZT, enabling tight regulation under varying load conditions. Its metallurgical bond ensures mechanical robustness and thermal stability in high-vibration environments.
The device features minimal capacitance (typical <1.5 pF at 0 V), low leakage (<0.05 µA at 14.5 V), and noise density of 1 µV/√Hz - optimized for low-phase-noise references and analog signal conditioning where spectral purity matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 19.0 V ±1% at 250 mA - enables precise 19 V rail regulation with minimal calibration drift. |
| Power Dissipation | 500 mW at 25 °C, derating linearly to zero at 175 °C - supports operation in high-temperature enclosures without forced cooling. |
| Zener Impedance (ZZT) | 150 Ω at 250 mA - maintains voltage stability against load transients in feedback loops. |
| Noise Density | 1 µV/√Hz - minimizes added noise in precision analog references and sensor excitation circuits. |
| Temp. Coefficient (αVZ) | +0.090 %/°C - predictable positive drift simplifies compensation in wide-temperature-range instrumentation. |
| Reverse Leakage (IR) | <0.05 µA at 14.5 V - ensures negligible quiescent current in battery-backed or ultra-low-power standby modes. |
| Package | DO-213AA (SOD-80) glass MELF - hermetically sealed, RoHS-compliant (e3), and qualified to JANS level per MIL-PRF-19500/435. |
Pinout & Package
DO-213AA (SOD-80) glass MELF package: cylindrical, hermetically sealed, cathode band marked on one end. Terminals are tin-lead or annealed matte-tin plated; polarity: banded end = cathode (positive during Zener operation).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unbanded end) | Reference ground node | Connected to system ground or lower-potential rail; forms return path for Zener current. |
| Cathode (banded end) | Regulated output node | Provides stable 19.0 V output when reverse-biased; must be held at higher potential than anode. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 qualification | Qualified to JANS level - certified for space-grade, nuclear-hardened, and mission-critical applications. |
| Metallurgical bonding | Eliminates wire bonds and interfacial delamination - improves thermal cycling endurance and shock resistance. |
| Low noise density | 1 µV/√Hz at 19 V - directly reduces integrated RMS noise in voltage references used in ADC/DAC biasing. |
| Hermetic glass seal | Prevents moisture ingress and parameter shift over decades - essential for long-life embedded systems. |
| ESD immunity | Non-sensitive per MIL-STD-750 Method 1020 - survives handling without protection circuitry in cleanroom assembly. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CDLL4113-1 | Same 19.0 V, 1% Zener voltage and DO-213AA package; commercial-grade (non-mil) with RoHS e3 option. | Lacks MIL-PRF-19500/435 screening; suitable for non-critical industrial or telecom infrastructure. | Select CDLL4113-1 when JANS qualification, radiation hardness, or extended temperature validation are not required. |
| 1N4113UR-1 | Same 19.0 V, 5% tolerance (not 1%), identical DO-213AA package and mil-qualification levels (JAN/JANTXV/JANS). | Higher voltage tolerance increases design margin but reduces accuracy in precision references. | Choose 1N4113UR-1 only if system-level calibration accommodates ±5% VZ variation and tighter tolerance is unnecessary. |
Compared with CDLL4113-1 and 1N4113UR-1, the 1N4113DUR-1/TR uniquely combines 1% tolerance, JANS-level qualification, and RoHS-compliant tape-and-reel packaging - making it the sole choice for high-reliability, production-ready, and environmentally compliant 19 V reference designs.

FAQ
What is the Zener voltage tolerance of the 1N4113DUR-1/TR?
The 1N4113DUR-1/TR has a nominal Zener voltage of 19.0 V with a tight ±1% tolerance, confirmed in the Electrical Characteristics table on page 4 of T4-LDS-0245 Rev. 2. This tolerance is achieved via the "D" suffix in the nomenclature and applies at 250 mA test current and 25 °C ambient.
Is the 1N4113DUR-1/TR qualified to JANS level?
Yes, the 1N4113DUR-1/TR is qualified to JANS level per MIL-PRF-19500/435, as explicitly stated in the DESCRIPTION section (page 1) and PART NOMENCLATURE (page 2). The "DUR-1" suffix denotes the DO-213AA package and 1% tolerance, while JANS screening is available upon order prefixing with "JANS".
What does the "TR" suffix mean in 1N4113DUR-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-481-1-A standard using 12 mm carrier tape - confirmed in the MECHANICAL and PACKAGING section (page 2). This format supports automated SMT placement and is standard for volume production orders of the 1N4113DUR-1/TR.
Does the 1N4113DUR-1/TR meet RoHS requirements?
Yes, the 1N4113DUR-1/TR is RoHS compliant, indicated by the "e3" designation in the nomenclature per the PART NOMENCLATURE chart (page 2). RoHS compliance applies to commercial-grade versions only; mil-spec variants may use tin-lead plating unless specified otherwise.
What is the maximum reverse leakage current for the 1N4113DUR-1/TR?
The maximum reverse leakage current (IR) for the 1N4113DUR-1/TR is 0.05 µA at 14.5 V, as specified in the ELECTRICAL CHARACTERISTICS table (page 4). This ultra-low leakage supports battery-powered and low-quiescent-current applications where standby power budget is constrained.
