Product details
Overview
JAN1N4111-1 from Microsemi is a 500 mW, 17.0 V ±5% metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JAN1N4111-1 datasheet, JAN1N4111-1 pinout, JAN1N4111-1 application, or JAN1N4111-1 equivalent, key selection criteria include its 17.0 V nominal Zener voltage at 250 mA test current, 100 Ω dynamic impedance, 0.05 µA max reverse leakage at 13.0 V, +0.090 %/°C temperature coefficient, and hermetically sealed glass construction for stable operation from –65 °C to +175 °C.
Technical Context
This device operates as a precision shunt voltage regulator with a sharp breakdown knee at IZK = 250 mA, leveraging internal metallurgical bonding to minimize parameter drift under thermal stress and radiation exposure. Its low noise density (1 µV/√Hz typical at 17 V) and minimal capacitance support stable reference generation in analog signal chains.
The JAN1N4111-1 exhibits a positive temperature coefficient (+0.090 %/°C), enabling predictable voltage drift over temperature - critical for biasing circuits in military-grade amplifiers and sensor front-ends where long-term calibration stability is required.
Key Specifications

|---|---|
| Zener Voltage VZ | 17.0 V at IZT = 250 mA - defines precise regulation point for feedback loops in DC-DC converters. |
| Zener Impedance ZZT | 100 Ω - ensures minimal output voltage variation under load current changes up to 250 mA. |
| Reverse Leakage IR | 0.05 µA @ VR = 13.0 V - guarantees negligible standby current in low-power reference circuits. |
| Power Dissipation | 500 mW @ TC = 25 °C - supports continuous regulation in compact through-hole designs with adequate lead heatsinking. |
| Temp. Coefficient αVZ | +0.090 %/°C - enables predictable, monotonic voltage shift across –65 °C to +175 °C operating range. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4111US | Same 17.0 V Zener voltage and DO-35 package, but commercial-grade (non-mil-qualified) and RoHS-compliant. | Lacks JAN-level screening and radiation hardness; unsuitable for aerospace or defense deployments. | Select only for cost-sensitive industrial prototypes where full MIL-PRF-19500/435 compliance is not required. |
| JANTX1N4111 | Identical electrical specs and DO-35 package, but qualified to JANTX level (higher screening than JAN) with tighter parametric limits. | Approved for higher-reliability programs including missile guidance systems; requires additional qualification documentation. | Choose when design mandates enhanced burn-in, life testing, and lot traceability beyond JAN requirements. |
Compared with JAN1N4111-1, 1N4111US offers lower cost and RoHS compliance but no radiation hardness or military screening, while JANTX1N4111 provides superior reliability assurance at higher procurement overhead - making JAN1N4111-1 the optimal balance of performance, qualification, and supply chain maturity for Tier-1 defense contractors.

FAQ
What is the Zener voltage tolerance for JAN1N4111-1?
The JAN1N4111-1 has a nominal Zener voltage of 17.0 V with a standard tolerance of ±5%, as defined in the JEDEC-registered specification and confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tolerance applies under thermal equilibrium at 25 °C with IZT = 250 mA.
Is JAN1N4111-1 compatible with lead-free soldering processes?
JAN1N4111-1 features tin-lead plated leads per MIL-STD-750 method 2026 and is rated for solder temperature of 260 °C for 10 seconds. While RoHS-compliant versions (e.g., 1N4111-1e3) exist for commercial grades, the JAN-level JAN1N4111-1 itself is not RoHS-compliant and requires tin-lead soldering profiles.
What is the maximum Zener current IZM for JAN1N4111-1?
The maximum Zener current IZM for JAN1N4111-1 is 13.0 mA, as specified in the Electrical Characteristics table. This value corresponds to the current at which the device delivers its rated 500 mW power dissipation at VZ = 17.0 V, assuming linear derating above 50 °C case temperature.
Does JAN1N4111-1 have radiation hardness certification?
Yes, JAN1N4111-1 is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded glass construction provides tolerance to total ionizing dose (TID) environments, making it suitable for low-earth orbit and nuclear instrumentation applications without supplemental shielding.
How does the temperature coefficient affect JAN1N4111-1 in wide-temperature designs?
JAN1N4111-1 has a temperature coefficient of +0.090 %/°C, meaning its Zener voltage increases by approximately 15.3 mV per °C rise across its 17.0 V nominal value. This predictable positive drift allows designers to compensate for thermal effects in closed-loop regulators or select complementary components in temperature-stable references.
