Product details
Overview
JANTX1N4616D-1 from Microsemi is a 500 mW, 2.2 V Zener diode in DO-35 glass package with 1% voltage tolerance, metallurgically bonded construction, and MIL-PRF-19500/435 JANTX qualification for high-reliability voltage regulation in aerospace power conditioning circuits.
For engineers reviewing the JANTX1N4616D-1 datasheet, JANTX1N4616D-1 pinout, JANTX1N4616D-1 application, or JANTX1N4616D-1 equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), thermal resistance (250 °C/W junction-to-lead), and hermetic DO-35 packaging for radiation-hardened environments.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 2.2 V at 250 mA test current, exhibiting a temperature coefficient of –0.075 %/°C and dynamic impedance of 1300 Ω at IZT. Its metallurgical bond ensures stable breakdown characteristics under thermal cycling.
Rated for –65 °C to +175 °C junction temperature, it delivers regulated output across wide current ranges (IZK to IZM = 100 mA) while maintaining low reverse leakage (IR ≤ 2.0 µA at VR = 1.0 V) and minimal capacitance per Figure 3.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.2 V ±1% at 250 mA - enables precise low-voltage reference in analog sensor biasing and power monitor circuits. |
| Power Dissipation | 500 mW at TC = 25 °C - supports continuous regulation in compact, unheatsinked military PCB layouts. |
| Dynamic Impedance ZZT | 1300 Ω at IZT - limits output voltage variation under load transients in feedback-sensing applications. |
| Noise Density ND | 1 µV/√Hz at IZT - critical for low-noise reference generation in precision ADC front-ends and RF bias networks. |
| Temp Coefficient αVZ | –0.075 %/°C - ensures predictable drift compensation in temperature-stable voltage references. |
| Reverse Leakage IR | ≤2.0 µA at VR = 1.0 V - minimizes standby current loss in battery-backed hold-up circuits. |
| Junction Temp Range | –65 °C to +175 °C - validated for operation in avionics environmental chambers and space-grade thermal cycles. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by band; operated with banded end positive for Zener regulation. Hermetically sealed, tin-lead plated leads solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system GND or low-impedance return path; defines Zener regulation polarity. |
| Cathode | Regulated output node | Banded terminal supplies stable 2.2 V when reverse-biased; must be decoupled for noise-sensitive loads. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JANTX qualification | Validated reliability for flight-critical subsystems including power sequencers and telemetry regulators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4616D-1 | Higher screening level (JANTXV vs JANTX); tighter parametric limits on ZZT and αVZ per MIL-PRF-19500/435. | Required for systems demanding extended burn-in and radiation testing beyond standard JANTX. | Select when full JANTXV qualification documentation and enhanced lot traceability are mandated. |
| 1N4616US-1 | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Suitable only for reflow-soldered PCBs where through-hole mounting is prohibited. | Choose for automated assembly lines needing SMT compatibility without performance trade-offs. |
Compared with JANTX1N4616D-1, the JANTXV variant adds screening rigor for extreme environments, while the 1N4616US-1 offers identical regulation in a space-constrained SMT footprint-neither is pin-compatible due to differing packages and mechanical interfaces.

FAQ
What is the Zener voltage tolerance for JANTX1N4616D-1?
JANTX1N4616D-1 has a nominal Zener voltage of 2.2 V with ±1% tolerance, as indicated by the "D" suffix in the part number per Microsemi's nomenclature. This tight tolerance is verified during JANTX-level screening and supports precision voltage referencing in calibrated systems where drift must remain within 22 mV over temperature and life.
Is JANTX1N4616D-1 RoHS compliant?
No, JANTX1N4616D-1 is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts; JANTX-level devices retain tin-lead plating to meet MIL-STD-750 solderability requirements and ensure proven reliability in legacy military assemblies.
What is the maximum Zener current IZM for JANTX1N4616D-1?
The maximum Zener current IZM for JANTX1N4616D-1 is 100 mA, derived from its 500 mW power rating and 2.2 V Zener voltage (P = V × I → I = 0.5 W / 2.2 V ≈ 227 mA, derated to 100 mA per electrical characteristics table). This value ensures safe operation within thermal limits at lead temperature TL = 50 °C.
How does the temperature coefficient affect JANTX1N4616D-1 in wide-temperature applications?
JANTX1N4616D-1 has a temperature coefficient αVZ of –0.075 %/°C, meaning its Zener voltage decreases by approximately 1.65 mV/°C from 25 °C baseline. In a –55 °C to +125 °C range, this results in a total drift of ±11.25 mV, which is acceptable for non-critical biasing but requires compensation in metrology-grade references.
Can JANTX1N4616D-1 be used in surface-mount designs?
No, JANTX1N4616D-1 uses a DO-35 axial-leaded glass package and is not suitable for surface-mount assembly. For SMT equivalents, consider the 1N4616US-1 in DO-213AA package - same electrical specs but different mechanical form factor and soldering process requirements.
