Product details
Overview
JAN1N4116D-1 from Microsemi is a 500 mW, 24.0 V Zener diode in DO-35 glass package with 1% voltage tolerance, metallurgically bonded construction, and MIL-PRF-19500/435 qualification to JANS level. It regulates voltage across wide current (250 mA test) and temperature (-65°C to +175°C) ranges, and delivers low noise density (1 µV/√Hz) for precision reference applications in aerospace power supplies.
For engineers reviewing the JAN1N4116D-1 datasheet, JAN1N4116D-1 pinout, JAN1N4116D-1 application, or JAN1N4116D-1 equivalent, key selection criteria include Zener voltage tolerance (1%), dynamic impedance (150 Ω at 250 mA), junction-to-lead thermal resistance (250 °C/W), and radiation-hardened operation per MicroNote 050.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 24.0 V at 250 mA test current (IZT), exhibiting a positive temperature coefficient of +0.090 %/°C. Its metallurgical bond ensures stable breakdown characteristics under thermal cycling and high-reliability stress conditions.
Designed for hermetic axial-leaded mounting, it maintains regulation with ≤0.01 µA reverse leakage at 18.3 V (VR), and achieves dynamic impedance of 150 Ω measured at 10% rms AC modulation superimposed on IZT - critical for low-noise analog references.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 24.0 V ±1% at 250 mA - defines precise regulation point for feedback loops in regulated DC-DC converters |
| Power Dissipation | 500 mW at 25°C, linearly derated to zero at 175°C - sets maximum continuous thermal load on PCB traces |
| Dynamic Impedance ZZT | 150 Ω at 250 mA - determines output voltage stability under varying load current |
| Noise Density ND | 1 µV/√Hz - enables use in low-noise bandgap references and instrumentation amplifiers |
| Reverse Leakage IR | ≤0.01 µA at 18.3 V - ensures minimal error current in high-impedance bias networks |
| Temp Coefficient αVZ | +0.090 %/°C - allows predictable drift compensation in temperature-stable references |
| Junction Temp Range | -65°C to +175°C - supports operation in extended-environment avionics and downhole electronics |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4116US-1 | Same electrical specs but in DO-213AA surface-mount package - no axial leads, 2.5 mm × 1.3 mm footprint | Requires SMT reflow assembly; unsuitable for through-hole prototyping or high-vibration mechanical retention | Select when board space is constrained and automated assembly is used |
| JANTXV1N4116D-1 | Identical electrical and mechanical specs, but qualified to JANTXV level - tighter screening, enhanced lot traceability, and extended burn-in | Required for mission-critical subsystems where failure modes demand higher confidence than JANS-level screening | Select when program mandates JANTXV reliability assurance beyond JANS |
Compared with JAN1N4116D-1, the 1N4116US-1 offers identical regulation performance in a compact SMT form factor, while JANTXV1N4116D-1 provides augmented reliability screening - enabling trade-offs between manufacturability and assurance level without sacrificing voltage accuracy or thermal capability.

FAQ
What is the Zener voltage tolerance of JAN1N4116D-1?
JAN1N4116D-1 has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its nomenclature. This means its nominal 24.0 V Zener voltage is guaranteed between 23.76 V and 24.24 V at 250 mA test current and 25°C, supporting high-accuracy regulation in feedback networks without post-manufacture trimming.
Is JAN1N4116D-1 qualified for space applications?
Yes, JAN1N4116D-1 is qualified to JANS level per MIL-PRF-19500/435, which includes rigorous screening for space-grade reliability - such as 100% lot acceptance testing, radiation hardness assurance per MicroNote 050, and extended temperature cycling. The JAN1N4116D-1 is approved for use in satellite power systems and onboard instrumentation.
What is the maximum reverse leakage current for JAN1N4116D-1?
The maximum reverse leakage current (IR) for JAN1N4116D-1 is 0.01 µA at VR = 18.3 V, measured at 25°C. This ultra-low leakage ensures minimal error contribution in high-impedance bias networks and precision reference dividers, preserving accuracy in low-power sensor interfaces where JAN1N4116D-1 serves as primary voltage standard.
Can JAN1N4116D-1 be used in surface-mount designs?
No - JAN1N4116D-1 uses the axial-leaded DO-35 (DO-204AH) glass package and is not compatible with surface-mount assembly. For SMT implementation, the functionally equivalent 1N4116US-1 in DO-213AA package should be selected; it shares identical electrical specifications but requires reflow soldering and lacks axial mechanical retention.
What is the thermal resistance from junction to lead for JAN1N4116D-1?
The thermal resistance from junction to lead (RθJL) for JAN1N4116D-1 is 250 °C/W when measured with 3/8 inch (10 mm) lead length from body, per MIL-PRF-19500/435 test conditions. This value directly determines allowable power dissipation in lead-mounted configurations and informs heatsinking decisions in high-reliability JAN1N4116D-1 deployments.
