Product details
Overview
JAN1N4616-1/TR from Microsemi is a 2.2 V, 500 mW metallurgically bonded glass Zener diode in DO-35 axial package, qualified to JANS level per MIL-PRF-19500/435, with 1% voltage tolerance, 1300 Ω dynamic impedance at 250 mA test current, and -0.075 %/°C temperature coefficient - used for precision voltage reference and regulation in military avionics power supplies.
For engineers reviewing the JAN1N4616-1/TR datasheet, JAN1N4616-1/TR pinout, JAN1N4616-1/TR application, or JAN1N4616-1/TR equivalent, key selection criteria include Zener voltage stability under thermal stress, low noise density (1 µV/√Hz), hermetic DO-35 packaging for radiation-hardened environments, and compliance with MIL-PRF-19500/435 reliability levels.
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 2.2 V at 250 mA test current (IZT), exhibiting a tight ±1% tolerance and a negative temperature coefficient of -0.075 %/°C. Its metallurgical bond construction ensures stable junction behavior across -65 °C to +175 °C operating range.
It delivers 500 mW average power dissipation with linear derating above 50 °C lead temperature, and achieves low noise density (1 µV/√Hz) and minimal capacitance - critical for low-drift analog references and high-reliability power conditioning circuits where ESD immunity and radiation hardness are mandatory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.2 V ±1% at 250 mA - enables precise low-voltage reference in regulated power rails. |
| Power Dissipation | 500 mW at 25 °C, derated linearly to zero at 175 °C - supports sustained operation in high-temp military enclosures. |
| Dynamic Impedance ZZT | 1300 Ω at IZT = 250 mA - ensures stable regulation under varying load current in feedback loops. |
| Temp Coefficient αVZ | -0.075 %/°C - provides predictable, compensatable drift in temperature-critical instrumentation. |
| Noise Density ND | 1 µV/√Hz - minimizes added noise in precision analog signal chains and sensor front-ends. |
| Reverse Leakage IR | 2.0 µA at VR = 1.0 V - guarantees low standby current in battery-backed or ultra-low-power systems. |
| Max Zener Current IZM | 100 mA - defines safe continuous operating limit before thermal runaway risk. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with hermetically sealed body, tin-lead or RoHS-compliant matte-tin plating, cathode indicated by band. Operated with banded end positive for Zener regulation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4616US-1 | Same electrical specs but in DO-213AA surface-mount package; no axial leads. | Used where PCB real estate is constrained and reflow assembly is required. | Select when automated SMT placement is needed and thermal path to copper is optimized. |
| JANTXV1N4616-1 | Identical Zener parameters but qualified to JANTXV level (not JANS); lower screening rigor. | Suitable for non-space-grade defense electronics where cost and lead time are prioritized over ultimate radiation tolerance. | Choose for ground-vehicle or naval systems where full JANS qualification is not mandated. |
Compared with JAN1N4616-1/TR, the 1N4616US-1 offers identical regulation performance in a space-saving SMT form, while JANTXV1N4616-1 trades JANS-level radiation assurance for faster procurement and lower unit cost - both require layout changes and do not share pinout compatibility.

FAQ
What is the Zener voltage tolerance for JAN1N4616-1/TR?
JAN1N4616-1/TR has a nominal Zener voltage of 2.2 V with a ±1% tolerance, as indicated by the "D" suffix in its nomenclature per MIL-PRF-19500/435. This tight tolerance ensures consistent regulation across production lots and temperature extremes, supporting precision analog functions in JAN-qualified systems.
Is JAN1N4616-1/TR compatible with lead-free soldering processes?
JAN1N4616-1/TR is RoHS compliant only in commercial-grade versions (e3 suffix); the JAN-level version uses tin-lead plating and is rated for 260 °C solder temperature for 10 seconds. For lead-free reflow, Microsemi recommends verifying thermal profile compatibility with the DO-35 glass body's thermal limits and using appropriate preheat ramp rates.
What is the maximum reverse leakage current for JAN1N4616-1/TR?
JAN1N4616-1/TR specifies a maximum reverse leakage current (IR) of 2.0 µA at VR = 1.0 V, measured at 25 °C. This low leakage supports ultra-low-power standby modes in battery-operated military radios and ensures minimal error contribution in high-impedance reference divider networks.
How does the temperature coefficient affect JAN1N4616-1/TR in wide-temperature applications?
JAN1N4616-1/TR has a temperature coefficient of -0.075 %/°C, meaning its Zener voltage decreases by approximately 1.65 mV per °C rise from 25 °C. This predictable negative drift allows system-level compensation in avionics reference designs and remains within specification across the full -65 °C to +175 °C junction temperature range.
Can JAN1N4616-1/TR be used as a replacement for commercial 1N4616-1?
JAN1N4616-1/TR shares identical electrical specifications with commercial 1N4616-1 but adds JAN-level screening, hermetic sealing, and extended temperature validation per MIL-PRF-19500/435. It is not a drop-in replacement in terms of qualification - systems requiring JAN certification must use JAN1N4616-1/TR to meet procurement specifications.
