Product details
Overview
JAN1N4111D-1 from Microsemi is a 500 mW, 17.0 V Zener voltage regulator diode in DO-35 (DO-204AH) axial-glass package, qualified to JANS level per MIL-PRF-19500/435, with 1% voltage tolerance, 100 Ω dynamic impedance at 250 mA test current, and +0.090 %/°C temperature coefficient - used for precision voltage reference and regulation in military-grade power supplies and analog signal conditioning circuits.
For engineers reviewing the JAN1N4111D-1 datasheet, JAN1N4111D-1 pinout, JAN1N4111D-1 application, or JAN1N4111D-1 equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), hermetic glass packaging, MIL-qualified reliability level, and thermal derating behavior from 500 mW at 25 °C to zero at 175 °C.
Technical Context
This device operates as a reverse-biased Zener regulator with metallurgically bonded junction, delivering stable 17.0 V output across 13.0 mA to 40 mA Zener current range while maintaining ±1% initial tolerance and +0.090 %/°C temperature coefficient. Its low capacitance (<1.5 pF typical at 17 V) and minimal leakage (<0.05 µA at 13.3 V) support high-frequency stability in reference and feedback paths.
Designed for high-reliability environments, it features hermetically sealed DO-35 glass construction, RoHS-compliant matte-tin plating (commercial versions only), and radiation-hardened performance per Microsemi MicroNote 050 - enabling use in aerospace, defense, and space-qualified systems where long-term parametric drift and environmental resilience are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 17.0 V at 250 mA test current - defines precise regulation point for feedback loops and reference generation |

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 17.0 V Zener, DO-213AA surface-mount package, identical electrical specs but different thermal resistance (RθJL = 200 °C/W vs. 250 °C/W) | Used where board space is constrained and reflow soldering is required; lacks axial mounting flexibility | Select when automated assembly and compact footprint outweigh axial lead serviceability needs |
| JANTXV1N4111D | Identical electrical and mechanical specs, but qualified to JANTXV level (not JANS); lower screening rigor, no radiation hardness documentation | Acceptable for ground-based military systems where full space qualification is not mandated | Choose for cost-sensitive programs requiring MIL-qualified reliability without radiation assurance |
Compared with JAN1N4111D-1, 1N4111US-1 offers identical regulation performance in SMT form but trades axial mounting and higher thermal resistance for board-area savings, while JANTXV1N4111D reduces qualification cost and documentation depth at the expense of radiation hardness and full JANS-level screening.

FAQ
What is the Zener voltage and tolerance of JAN1N4111D-1?
JAN1N4111D-1 has a nominal Zener voltage of 17.0 V at 250 mA test current with ±1% tolerance (denoted by the "D" suffix). This tight tolerance is verified per MIL-PRF-19500/435 screening and supports precision reference applications without post-production adjustment. The voltage remains stable across its rated current range and temperature extremes.
Is JAN1N4111D-1 suitable for space applications?
Yes, JAN1N4111D-1 is qualified to JANS level per MIL-PRF-19500/435 and documented as inherently radiation hard per Microsemi MicroNote 050. Its hermetic DO-35 package and metallurgical bond construction ensure parametric stability after total ionizing dose exposure up to 100 krad(Si), making it suitable for LEO satellite telemetry and onboard regulation.
What is the maximum power dissipation and thermal derating behavior of JAN1N4111D-1?
JAN1N4111D-1 has a rated average power dissipation of 500 mW at 25 °C, linearly derated to zero at 175 °C. Derating begins at 50 °C for lead temperature or 25 °C for ambient conditions on a standard FR4 board. This behavior directly impacts heatsinking requirements and maximum continuous Zener current in sustained regulation mode.
Does JAN1N4111D-1 have low noise performance suitable for precision analog circuits?
Yes, JAN1N4111D-1 delivers 1 µV/√Hz noise density at its 17.0 V Zener voltage - among the lowest in its voltage class. This performance is measured per Figure 1 in the official datasheet using a 1–3 kHz bandpass filter and enables use in high-resolution ADC references, precision comparators, and low-drift analog front-ends without added filtering.
How is polarity marked and how should JAN1N4111D-1 be connected in circuit?
JAN1N4111D-1 uses a cathode band to indicate polarity: the banded end is the cathode and must be held at a higher potential than the anode to operate in Zener breakdown. In regulation mode, the cathode connects to the voltage node being stabilized, and the anode connects to circuit ground or lower-potential rail - reverse connection results in forward conduction only.
