Product details
Overview
JANTX1N4616C-1/TR from Microsemi is a 2.2 V, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTX level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 1300 Ω dynamic impedance at 250 mA test current, and 1.0 µA maximum reverse leakage at 2.0 V. It serves as a precision voltage reference in military-grade power regulation and analog signal conditioning circuits.
For engineers reviewing the JANTX1N4616C-1/TR datasheet, JANTX1N4616C-1/TR pinout, JANTX1N4616C-1/TR application, or JANTX1N4616C-1/TR equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), MIL-qualified reliability, thermal resistance (250 °C/W junction-to-lead), and axial-leaded DO-35 mechanical compatibility for through-hole high-reliability PCBs.
Technical Context
This device operates in reverse breakdown to maintain stable 2.2 V output across wide current (250 mA IZT) and temperature (-65 to +175 °C) ranges. Its internal metallurgical bond ensures robust junction integrity under thermal cycling and radiation exposure.
Designed for high-reliability environments, it exhibits minimal capacitance (typical <2 pF), non-ESD-sensitive construction per MIL-STD-750 Method 1020, and inherent radiation hardness per Microsemi MicroNote 050 - critical for aerospace and defense systems requiring long-term parametric stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.2 V ±2% at 250 mA - enables precise low-voltage reference generation with tight tolerance for calibration-critical circuits. |
| Power Dissipation | 500 mW at 25 °C - supports stable regulation in compact through-hole designs without forced cooling. |
| Dynamic Impedance ZZT | 1300 Ω at 250 mA - determines output voltage variation under load changes; suitable for moderate-precision regulation. |
| Reverse Leakage IR | 1.0 µA max at 2.0 V - ensures minimal quiescent current draw in battery-backed or low-power standby modes. |
| Noise Density ND | 1 µV/√Hz - ultra-low broadband noise ideal for sensitive analog front-ends and precision instrumentation references. |
| Temp Coefficient αVZ | -0.075 %/°C - predictable negative drift allows compensation in temperature-stable reference designs. |
| Junction Temp Range | -65 to +175 °C - validated operation across extreme environmental conditions typical of avionics and space electronics. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by band; leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 Method 2026. Weight ≈ 0.2 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal / Zener cathode reference ground | Connected to circuit ground or lower-potential node; reverse-biased operation requires cathode at higher potential. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTX1N4616D-1/TR | ±1% Zener voltage tolerance vs. ±2% for JANTX1N4616C-1/TR; otherwise identical electrical and mechanical specs. | Suitable where tighter initial calibration is required, e.g., metrology-grade test equipment. | Select JANTX1N4616D-1/TR only if system-level calibration budget demands sub-2% error margin. |
| 1N4616US-1 | Same 2.2 V nominal Zener voltage but in surface-mount DO-213AA package; no MIL qualification; commercial grade only. | Applicable in cost-sensitive, high-volume commercial designs where JANTX reliability is not mandated. | Choose 1N4616US-1 for automated SMT assembly and RoHS compliance where military screening is unnecessary. |
Compared with JANTX1N4616C-1/TR, JANTX1N4616D-1/TR offers higher initial accuracy at same reliability level, while 1N4616US-1 trades qualification and axial mounting for SMT compatibility and lower cost - enabling trade-offs between precision, ruggedness, and manufacturability.

FAQ
What is the Zener voltage tolerance of JANTX1N4616C-1/TR?
JANTX1N4616C-1/TR has a nominal Zener voltage of 2.2 V with a tolerance of ±2%, as indicated by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is specified at 250 mA test current and 25 °C ambient temperature, and applies across the full qualified operating temperature range of -65 to +175 °C.
Is JANTX1N4616C-1/TR suitable for surface-mount assembly?
No, JANTX1N4616C-1/TR uses the axial-leaded DO-35 (DO-204AH) glass package and is intended for through-hole mounting. For surface-mount alternatives, consider the 1N4616US-1 in DO-213AA package - though it lacks MIL qualification and is commercial-grade only.
What does the "TR" suffix mean in JANTX1N4616C-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. This format is standard for volume orders and supports consistent feeding in high-throughput production lines while preserving JANTX-level reliability screening and traceability.
How is the cathode identified on JANTX1N4616C-1/TR?
The cathode of JANTX1N4616C-1/TR is marked by a distinct color band on the glass body. During Zener operation, the banded end must be held at a higher potential than the anode to achieve reverse-bias breakdown and deliver the regulated 2.2 V output.
Does JANTX1N4616C-1/TR require derating above 25 °C?
Yes, JANTX1N4616C-1/TR must be linearly derated starting at 25 °C ambient: its 500 mW power rating decreases to zero at +175 °C. Derating follows a slope of approximately 3.57 mW/°C when mounted on a typical FR4 board with 4 mm² copper pads, per Figure 2 in the T4-LDS-0245-2 datasheet.
