Product details
Overview
JANS1N4111C-1/TR from Microsemi is a 500 mW, 17.0 V ±2% tolerance, metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications. It delivers stable voltage regulation with 100 Ω dynamic impedance at 250 mA test current, 0.05 µA max reverse leakage at 13.0 V, and +0.090 %/°C temperature coefficient.
For engineers reviewing the JANS1N4111C-1/TR datasheet, JANS1N4111C-1/TR pinout, JANS1N4111C-1/TR application, or JANS1N4111C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), radiation-hardened construction, low noise density (1 µV/√Hz), and compliance with MIL-PRF-19500/435 JANS screening requirements for space-grade power regulation and reference circuits.
Technical Context
This device operates as a precision shunt voltage regulator in reverse-biased breakdown mode, with cathode band marking polarity. Its metallurgical bond ensures mechanical stability under thermal cycling and shock, critical for military avionics power supplies and satellite telemetry references.
The JANS1N4111C-1/TR exhibits a positive temperature coefficient (+0.090 %/°C), enabling predictable drift compensation in multi-diode reference strings. Its 100 Ω dynamic impedance at IZT = 250 mA and 13.0 V Zener voltage supports tight regulation across load currents from 10 mA to 13.0 mA (IZM).

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4111US-1 | Same 17.0 V ±2% Zener voltage, but in DO-213AA surface-mount package; no JANS qualification | Limited to commercial-grade PCB assembly; unsuitable for radiation environments or extended temperature ranges | Select only for cost-sensitive, non-military surface-mount designs where JANS screening is not required |
| JANTXV1N4111C-1 | Identical electrical specs and DO-35 package, but qualified only to JANTXV level (lower screening rigor than JANS) | Approved for high-reliability ground-based systems (e.g., radar, EW), but not certified for spaceflight or nuclear applications | Choose when full JANS radiation testing and lot acceptance testing are unnecessary, reducing procurement lead time and cost |
Compared with JANS1N4111C-1/TR, the JANTXV1N4111C-1 offers identical regulation performance at lower qualification cost, while the 1N4111US-1 trades hermeticity and reliability for SMT compatibility-neither is a drop-in replacement due to differing qualification levels or packaging.

FAQ
What is the Zener voltage and tolerance of JANS1N4111C-1/TR?
JANS1N4111C-1/TR has a nominal Zener voltage of 17.0 V with a ±2% tolerance, measured at 250 mA test current (IZT) under thermal equilibrium at 25 °C. This tolerance is confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1, where "C" in the part number explicitly denotes 2% tolerance per the nomenclature guide.
Is JANS1N4111C-1/TR radiation-hardened?
Yes, JANS1N4111C-1/TR is inherently radiation-hardened as described in Microsemi MicroNote 050 and qualified to JANS level per MIL-PRF-19500/435. Its metallurgically bonded structure and hermetic DO-35 package provide proven resistance to total ionizing dose (TID) and displacement damage, making it suitable for space and nuclear environments.
What is the maximum reverse leakage current for JANS1N4111C-1/TR?
The maximum reverse leakage current (IR) for JANS1N4111C-1/TR is 0.05 µA at VR = 13.0 V, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This ultra-low leakage supports battery-powered and low-power reference applications where standby current must be minimized.
Does JANS1N4111C-1/TR have a specified noise density?
Yes, JANS1N4111C-1/TR has a maximum noise density (ND) of 1 µV/√Hz at IZT = 250 mA, per the Electrical Characteristics table on page 3. This value applies to the 17.0 V variant and is consistent with the document's statement that noise falls quickly to 1 µV/√Hz at lower voltages (≤6.8 V), confirming its suitability for low-noise analog references.
What is the temperature coefficient of JANS1N4111C-1/TR?
JANS1N4111C-1/TR has a temperature coefficient (αVZ) of +0.090 %/°C, as listed in the Electrical Characteristics table on page 3. This positive coefficient is typical for Zener diodes above ~5 V and allows predictable, monotonic voltage drift with temperature-enabling compensation in multi-diode reference designs.
