Product details
Overview
JANTXV1N4111C-1 from Microsemi is a 500 mW, 17.0 V ±2% tolerance Zener diode in DO-35 glass package, qualified to JANTXV level per MIL-PRF-19500/435, with dynamic impedance of 100 Ω at 250 mA test current and max noise density of 1 μV/√Hz, used for precision voltage regulation in military-grade power supply references.
For engineers reviewing the JANTXV1N4111C-1 datasheet, JANTXV1N4111C-1 pinout, JANTXV1N4111C-1 application, or JANTXV1N4111C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), JANTXV reliability qualification, DO-35 axial-leaded hermetic packaging, thermal resistance (250 °C/W junction-to-lead), and low-noise performance below 1 μV/√Hz at 17 V.
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded construction ensuring stable breakdown characteristics across -65 °C to +175 °C. Its 100 Ω dynamic impedance at IZT = 250 mA and temperature coefficient of +0.090 %/°C define regulation accuracy under varying load and thermal conditions.
The diode exhibits minimal capacitance (typical <2 pF at 17 V) and is non-sensitive to ESD per MIL-STD-750 Method 1020. It delivers 17.0 V regulation with 0.05 µA max reverse leakage at VR = 13.0 V and supports linear derating from 500 mW at 25 °C to zero at 175 °C.

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% spec but in DO-213AA surface-mount package; no JANTXV qualification | Used where board space is constrained and MIL-spec not required | Select when automated SMT assembly is needed and radiation/military qualification is unnecessary |
| JANTXV1N4111D-1 | Identical electrical specs but ±1% Zener tolerance instead of ±2% | Applied in ultra-high-precision references where tighter initial accuracy is mandatory | Choose only if system-level calibration budget requires <1% initial voltage error |
Compared with JANTXV1N4111C-1, the 1N4111US-1 offers footprint reduction at the cost of reliability qualification, while JANTXV1N4111D-1 improves initial accuracy by 1% but increases cost and may require tighter thermal management due to identical power limits.

FAQ
What is the Zener voltage tolerance of JANTXV1N4111C-1?
JANTXV1N4111C-1 has a nominal Zener voltage of 17.0 V with a ±2% tolerance, meaning its actual regulation voltage falls between 16.66 V and 17.34 V when measured at IZT = 250 mA and TA = 25 °C. This tolerance is confirmed in the Electrical Characteristics table on page 3 of Microsemi's T4-LDS-0245-2 datasheet.
Is JANTXV1N4111C-1 qualified to JANTXV reliability level?
Yes, JANTXV1N4111C-1 is explicitly qualified to JANTXV level per MIL-PRF-19500/435, as stated in the "Qualified Levels" section on page 1 and confirmed in the part nomenclature table on page 2 of the datasheet. The "V" in JANTXV denotes enhanced screening including burn-in and life testing.
What is the maximum reverse leakage current for JANTXV1N4111C-1?
JANTXV1N4111C-1 has a maximum reverse leakage current (IR) of 0.05 µA at VR = 13.0 V, as specified in the Electrical Characteristics table on page 3. This low leakage supports high-impedance bias networks without significant current diversion.
Does JANTXV1N4111C-1 have radiation hardness?
Yes, JANTXV1N4111C-1 is inherently radiation hard as described in Microsemi MicroNote 050, a documented characteristic of its metallurgically bonded construction and DO-35 hermetic package. This makes it suitable for nuclear instrumentation and space applications without additional shielding.
What is the thermal resistance junction-to-lead for JANTXV1N4111C-1?
JANTXV1N4111C-1 has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when mounted with 3/8 inch (10 mm) lead length from body, per the Maximum Ratings table on page 1. This value guides heatsinking design for sustained 500 mW operation.
