Product details
Overview
JANS1N4111D-1/TR from Microsemi is a 17.0 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 applications including voltage reference stabilization in precision power supplies and radiation-hardened sensor interfaces.
For engineers reviewing the JANS1N4111D-1/TR datasheet, JANS1N4111D-1/TR pinout, JANS1N4111D-1/TR application, or JANS1N4111D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), noise density (1 µV/√Hz), dynamic impedance (100 Ω), temperature coefficient (+0.090 %/°C), and JANS-level qualification for extended temperature (-65 °C to +175 °C) operation.
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 17.0 V at 250 mA test current, exhibiting low dynamic impedance (100 Ω) and minimal noise density (1 µV/√Hz) - critical for stable reference generation in analog signal chains. Its metallurgical bond construction ensures mechanical robustness under thermal cycling and shock.
Designed for high-reliability environments, JANS1N4111D-1/TR meets MIL-PRF-19500/435 requirements across all electrical, environmental, and screening tests at JANS level, including hermetic sealing, radiation hardness per MicroNote 050, and ESD immunity per MIL-STD-750 Method 1020.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 17.0 V ±1% at IZT = 250 mA - enables precise voltage clamping in regulated power rails requiring tight tolerance. |
| Power Dissipation | 500 mW at TL = 25 °C, derated linearly to zero at 175 °C - supports continuous operation in high-temp avionics enclosures. |
| Dynamic Impedance ZZT | 100 Ω at IZT = 250 mA - ensures minimal output voltage variation under load transients in feedback references. |
| Noise Density | 1 µV/√Hz - provides ultra-low noise performance essential for high-resolution ADC/DAC reference circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4111D-1 | Same Zener voltage, tolerance, and package; qualified to JANTXV level (lower screening rigor than JANS). | Approved for high-reliability industrial and ground-based defense systems but not space-qualified. | Select when full JANS screening is not required and cost sensitivity is higher. |
| 1N4111UR-1 | Same electrical specs; surface-mount DO-213AA package instead of axial DO-35. | Used in automated SMT production lines where through-hole assembly is unavailable or undesirable. | Select for PCB space-constrained designs requiring RoHS-compliant SMT mounting. |
Compared with JANS1N4111D-1/TR, JANTXV1N4111D-1 offers reduced qualification depth for non-space programs, while 1N4111UR-1 trades axial leaded reliability for SMT manufacturability - neither is pin-compatible due to differing packages and screening levels.

FAQ
What is the Zener voltage tolerance of JANS1N4111D-1/TR?
JANS1N4111D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This tight tolerance is verified per MIL-PRF-19500/435 screening at JANS level and applies at 25 °C with IZT = 250 mA. The 17.0 V nominal value remains within 16.83–17.17 V across its qualified operating range, supporting precision reference design without post-manufacturing calibration.
Is JANS1N4111D-1/TR radiation hardened?
Yes, JANS1N4111D-1/TR is inherently radiation hard per Microsemi MicroNote 050, with documented tolerance to total ionizing dose (TID) relevant to low-earth orbit and terrestrial nuclear environments. Its metallurgically bonded glass construction and hermetic DO-35 package contribute to this hardness. Radiation performance data is included in the official qualification report for JANS-level devices, not extrapolated from commercial variants.
What does the "TR" suffix mean in JANS1N4111D-1/TR?
The "TR" suffix in JANS1N4111D-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This format is standard for volume orders and does not affect electrical or reliability specifications. The underlying device remains identical to the bulk version JANS1N4111D-1, retaining full JANS qualification and DO-35 mechanical form factor.
What is the maximum Zener current IZM for JANS1N4111D-1/TR?
The maximum Zener current IZM for JANS1N4111D-1/TR is 13.0 mA at 25 °C ambient, derived from its 500 mW power rating and 17.0 V Zener voltage (IZM = PM(AV)/VZ). This value assumes thermal equilibrium and accounts for linear derating above 50 °C lead temperature, reaching zero dissipation at 175 °C per Figure 2 in the datasheet.
How is polarity marked on JANS1N4111D-1/TR?
JANS1N4111D-1/TR uses a cathode band to indicate polarity: the banded end is the cathode and must be held positive relative to the anode for proper Zener regulation. This marking complies with JEDEC standards and is laser-etched or printed on the DO-35 glass body. Forward conduction occurs if polarity is reversed, potentially damaging the device under sustained bias.
