Product details
Overview
JAN1N4116-1 from Microsemi is a 500 mW, 24.0 V Zener diode in DO-35 glass package, qualified to JAN level per MIL-PRF-19500/435, with 1% voltage tolerance, 150 Ω dynamic impedance at 250 mA test current, and +0.090 %/°C temperature coefficient - used for precision voltage regulation in military power supplies and avionics reference circuits.
For engineers reviewing the JAN1N4116-1 datasheet, JAN1N4116-1 pinout, JAN1N4116-1 application, or JAN1N4116-1 equivalent, key selection criteria include Zener voltage stability across temperature, low noise density (≤1 µV/√Hz), hermetic glass packaging for high-reliability environments, and compliance with MIL-PRF-19500/435 JAN-level screening.
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded junction construction, enabling stable regulation over -65 °C to +175 °C junction temperature range. Its 24.0 V nominal Zener voltage is specified at 250 mA test current (IZT), with dynamic impedance measured at 150 Ω using 10% rms ac modulation superimposed on IZT.
Noise density is ≤1 µV/√Hz at 24 V, verified per Figure 1 test circuit with 1–3 kHz bandpass filtering. Temperature coefficient is tightly controlled at +0.090 %/°C, supporting stable reference performance in wide-temperature military systems without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 24.0 V ±1% at 250 mA - ensures precise reference accuracy for regulated power rails in aerospace systems. |
| Power Dissipation | 500 mW at 25 °C, derated linearly to zero at 175 °C - supports operation in high-temperature avionics enclosures. |
| Dynamic Impedance (ZZT) | 150 Ω at IZT = 250 mA - maintains tight regulation under load transients in analog sensor interfaces. |
| Reverse Leakage (IR) | ≤0.01 µA at VR = 18.3 V - minimizes quiescent current in battery-backed reference circuits. |
| Noise Density (ND) | ≤1 µV/√Hz at 25 °C - critical for low-noise instrumentation amplifiers and precision ADC references. |
| Temp Coefficient (αVZ) | +0.090 %/°C - enables predictable drift behavior in unheated military chassis over full operating range. |
| Junction Temp Range | -65 °C to +175 °C - qualified for missile guidance, radar, and space-qualified subsystems per MIL-PRF-19500/435. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4116US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads. | Required for PCB miniaturization in SWaP-constrained UAV payloads. | Select when automated SMT assembly and reduced board area outweigh axial-lead serviceability needs. |
| JANTXV1N4116-1 | Identical DO-35 package and Zener parameters, but screened to JANTXV level per MIL-PRF-19500/435. | Mandatory for Class V spaceflight components requiring extended life testing and lot traceability. | Select when mission-critical redundancy, 100% lot acceptance testing, or radiation tolerance beyond JAN level is required. |
Compared with JAN1N4116-1, 1N4116US-1 enables higher-density layouts but sacrifices hand-soldering accessibility, while JANTXV1N4116-1 adds screening rigor and lifetime validation at higher cost - both retain identical 24.0 V regulation behavior and thermal derating profile.

FAQ
What is the Zener voltage tolerance for JAN1N4116-1?
JAN1N4116-1 has a nominal Zener voltage of 24.0 V with ±1% tolerance, confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tighter tolerance eliminates need for post-production calibration in precision reference designs and is achieved via 1% binning during final test.
Is JAN1N4116-1 RoHS compliant?
No, JAN1N4116-1 is not RoHS compliant. Per the nomenclature table on page 2, the "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions. JAN1N4116-1 carries no e3 suffix and uses tin-lead plating per MIL-STD-750, making it exempt from RoHS for defense applications.
What is the maximum Zener current (IZM) for JAN1N4116-1?
The maximum Zener current IZM for JAN1N4116-1 is 40 mA, as specified in the Electrical Characteristics table on page 3. This value corresponds to the current at which the device reaches its rated 500 mW dissipation at 24.0 V, assuming ideal thermal conditions at 25 °C ambient.
Does JAN1N4116-1 require heatsinking in typical applications?
No, JAN1N4116-1 does not require external heatsinking in standard applications. Its thermal resistance junction-to-lead is 250 °C/W with 10 mm lead length, and power derating begins only above 50 °C lead temperature - sufficient for most through-hole mounted military PCBs with 1 oz copper.
How is polarity marked on JAN1N4116-1?
Polarity on JAN1N4116-1 is marked by a visible cathode band on the glass body; the banded end is the cathode and must be biased positively relative to the anode to achieve Zener regulation. This marking complies with JEDEC standards and is verified in the Mechanical and Packaging section on page 2.
