Product details
Overview
JANS1N4113D-1/TR from Microsemi is a 19.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense voltage regulation. It delivers stable reference voltage across wide current (250 mA test) and temperature (–65 °C to +175 °C) ranges with low dynamic impedance (150 Ω) and minimal noise density (1 µV/√Hz).
For engineers reviewing the JANS1N4113D-1/TR datasheet, JANS1N4113D-1/TR pinout, JANS1N4113D-1/TR application, or JANS1N4113D-1/TR equivalent, key selection criteria include its JANS-level radiation hardness, 1% Zener voltage tolerance, DO-35 axial-leaded hermetic packaging, and verified thermal resistance (250 °C/W junction-to-lead at 10 mm lead length).
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond construction ensures mechanical robustness under thermal cycling and shock, critical for space-grade applications.
It exhibits a positive temperature coefficient of +0.090 %/°C and maintains ≤0.05 µA reverse leakage at VR = 15.2 V, enabling stable biasing in low-power analog references and overvoltage protection circuits where long-term parametric drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 19.0 V ±1% at 250 mA - enables precise 19 V reference generation with tight production yield control. |
| Power Dissipation | 500 mW at TC = 25 °C - supports continuous regulation in compact, conduction-cooled designs. |
| Zener Impedance ZZT | 150 Ω at IZT = 250 mA - ensures minimal output voltage variation under load transients. |
| Noise Density ND | 1 µV/√Hz - critical for low-noise analog references in instrumentation and telemetry front-ends. |
| Reverse Leakage IR | ≤0.05 µA at VR = 15.2 V - guarantees negligible quiescent current draw in standby regulation paths. |
| Temp Coefficient αVZ | +0.090 %/°C - allows predictable, monotonic voltage drift over –65 °C to +175 °C operating range. |
| Junction Temp Range | –65 °C to +175 °C - validated for operation in extreme environments including satellite payload bays and missile guidance systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4113D-1 | Same electrical specs and DO-35 package; qualified to JANTXV (not JANS) per MIL-PRF-19500/435. | Lacks full JANS screening (e.g., burn-in, lot acceptance tests); unsuitable for Class S space missions. | Select only for high-reliability ground-based military systems where JANS is not mandated. |
| 1N4113UR-1 | Same 19.0 V/1% spec but in DO-213AA surface-mount package; no JANS qualification. | Enables automated assembly but lacks radiation hardness and extended temperature validation. | Choose for commercial or industrial PCBs requiring reflow compatibility and smaller footprint. |
Compared with JANS1N4113D-1/TR, JANTXV1N4113D-1 offers identical performance with reduced screening depth, while 1N4113UR-1 trades hermeticity and radiation tolerance for SMT manufacturability - neither is a drop-in replacement for JANS-critical deployments.

FAQ
What is the Zener voltage tolerance and test current for JANS1N4113D-1/TR?
JANS1N4113D-1/TR has a nominal Zener voltage of 19.0 V with ±1% tolerance, measured at a Zener test current (IZT) of 250 mA. This tight tolerance ensures high accuracy in precision reference applications where voltage drift must remain within ±0.19 V across production lots and temperature extremes.
Is JANS1N4113D-1/TR suitable for space applications?
Yes, JANS1N4113D-1/TR is qualified to JANS level per MIL-PRF-19500/435 and inherently radiation-hardened to ≥100 krad(Si), making it suitable for Class S space applications including LEO satellites and launch vehicle electronics where long-term parametric stability is mandatory.
What package type and marking does JANS1N4113D-1/TR use?
JANS1N4113D-1/TR uses the hermetically sealed DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by a visible band. The part number "1N4113" is laser-marked on the body, and the "D" suffix denotes 1% voltage tolerance per JEDEC nomenclature.
How does the metallurgical bond construction benefit JANS1N4113D-1/TR reliability?
The metallurgical bond in JANS1N4113D-1/TR eliminates traditional wire bonds, preventing interfacial failure under mechanical shock (>100,000 g) and thermal cycling (–65 °C to +175 °C). This construction directly enables its qualification for JANS-level screening and sustained operation in missile guidance and satellite systems.
What is the maximum reverse leakage current for JANS1N4113D-1/TR at rated conditions?
JANS1N4113D-1/TR specifies a maximum reverse leakage current (IR) of ≤0.05 µA at VR = 15.2 V and TA = 25 °C. This ultra-low leakage ensures minimal power loss and stable regulation in high-impedance bias networks used in radiation detection and precision telemetry circuits.
