Product details
Overview
JAN1N4111D-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 voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4111D-1/TR datasheet, JAN1N4111D-1/TR pinout, JAN1N4111D-1/TR application, or JAN1N4111D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), noise density (1 µV/√Hz), dynamic impedance (100 Ω), and JANS-level radiation hardness for mission-critical analog reference circuits.
Technical Context
This device operates as a precision shunt voltage regulator with cathode-banded polarity, requiring reverse-bias operation where the banded end is positive relative to the anode. It delivers stable 17.0 V regulation at 250 mA test current with temperature coefficient of +0.090 %/°C.
Its metallurgical bond construction enables low noise (1 µV/√Hz), minimal capacitance (typ. <2 pF), and inherent radiation hardness per Microsemi MicroNote 050 - critical for space-grade analog references and voltage references in hardened instrumentation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4111US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads | Used where PCB real estate is constrained and reflow assembly required | Select when transitioning from through-hole to SMT without changing reference topology |
| JANTXV1N4111D | Identical Zener voltage, tolerance, and qualification level but lacks TR tape-and-reel packaging | Preferred for manual prototyping or low-volume hand-soldered assemblies | Select when tape-and-reel automation is not needed and JANTXV-level screening suffices |
Compared with JAN1N4111D-1/TR, 1N4111US-1 offers identical regulation performance in a smaller footprint but requires SMT process control, while JANTXV1N4111D provides matching reliability without automated handling - enabling flexible sourcing across production and R&D phases.

FAQ
What is the Zener voltage and tolerance of JAN1N4111D-1/TR?
JAN1N4111D-1/TR has a nominal Zener voltage of 17.0 V with ±1% tolerance at 250 mA test current. This tight tolerance is achieved via post-process screening and is specified per MIL-PRF-19500/435. The device maintains this regulation across its full operating temperature range of –65 °C to +175 °C, making JAN1N4111D-1/TR suitable for high-accuracy reference applications where calibration stability is critical.
Is JAN1N4111D-1/TR qualified to JANS level?
Yes, JAN1N4111D-1/TR is fully qualified to JANS level per MIL-PRF-19500/435, including rigorous screening for burn-in, temperature cycling, and radiation hardness. This qualification confirms its suitability for spaceflight and nuclear environments. Each JAN1N4111D-1/TR lot is accompanied by full test reports and traceability documentation, distinguishing it from commercial or JANTXV variants.
What is the noise performance of JAN1N4111D-1/TR?
JAN1N4111D-1/TR exhibits a noise density of 1 µV/√Hz at 250 mA, measured in the 1 kHz–3 kHz band per Figure 1 of the datasheet. This ultra-low noise stems from its metallurgically bonded construction and optimized junction design. For precision analog systems such as ADC references or low-noise amplifier biasing, this performance makes JAN1N4111D-1/TR significantly quieter than standard Zeners above 6.8 V.
What package type does JAN1N4111D-1/TR use?
JAN1N4111D-1/TR uses the hermetically sealed DO-35 (DO-204AH) axial-leaded glass package with tin-lead or RoHS-compliant matte-tin plating. Its dimensions conform to MIL-STD-1835, with lead length 1.0–1.5 inches and body diameter 0.056–0.090 inches. The "TR" suffix indicates tape-and-reel packaging per EIA-296, enabling automated placement in high-mix defense manufacturing lines.
How does the temperature coefficient affect JAN1N4111D-1/TR in practical use?
JAN1N4111D-1/TR has a temperature coefficient of +0.090 %/°C, meaning its Zener voltage increases by approximately 15.3 mV per °C rise above 25 °C. This predictable positive drift allows designers to implement simple two-point calibration or passive compensation networks. In contrast to negative-coefficient Zeners, JAN1N4111D-1/TR avoids crossover points, ensuring monotonic behavior across –65 °C to +175 °C - a key advantage in unheated spacecraft bays.
