Product details
Overview
JANTX1N4108D-1/TR from Microsemi is a 14.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4108D-1/TR datasheet, JANTX1N4108D-1/TR pinout, JANTX1N4108D-1/TR application, or JANTX1N4108D-1/TR equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), radiation hardness, hermetic glass sealing, and military-grade thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 14.0 V at 250 mA test current (IZT), exhibiting a positive temperature coefficient of +0.085 %/°C and dynamic impedance of 200 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and mechanical stress.
Designed for operation in reverse-biased mode with cathode band indicating polarity, it delivers regulated output across wide current ranges (IZK to IZM = 10.7 mA to 40 mA) while maintaining low leakage (IR ≤ 0.05 µA at VR = 11.2 V) and minimal capacitance (typ. <2 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 14.0 V ±1% at 250 mA - enables precise reference generation in analog circuits requiring tight voltage stability. |
| Power Dissipation | 500 mW at 25 °C, linearly derated to zero at 175 °C - supports operation in high-temp environments with appropriate PCB copper area. |
| Zener Impedance ZZT | 200 Ω at 250 mA - ensures low output impedance for effective ripple suppression in regulated supplies. |
| Noise Density ND | 1 µV/√Hz at 14 V - critical for low-noise references in precision instrumentation and ADC/DAC biasing. |
| Reverse Leakage IR | ≤0.05 µA at 11.2 V - minimizes standby current loss in battery-backed or ultra-low-power systems. |
| Temp Coefficient αVZ | +0.085 %/°C - allows predictable drift compensation in temperature-critical voltage references. |
| Junction Temp Range | –65 to +175 °C - validated for extended-range operation in avionics, space, and downhole electronics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4108D-1 | Higher qualification level (JANTXV vs JANTX); tighter screening, enhanced burn-in, and extended life testing. | Required for mission-critical subsystems where failure probability must be <10⁻⁶ per 1000 hrs. | Select when full JANTXV screening per MIL-PRF-19500/435 is mandated by program spec. |
| 1N4108US-1TR | Same electrical specs but in surface-mount DO-213AA package; no axial leads. | Used where board space is constrained and automated SMT assembly is required. | Choose for compact PCB layouts needing identical regulation performance without through-hole mounting. |
Compared with JANTX1N4108D-1/TR, JANTXV1N4108D-1 adds screening rigor for ultra-high-reliability use, while 1N4108US-1TR offers identical regulation in a space-saving SMT form factor - neither is pin-compatible due to differing packages, but both maintain 14.0 V ±1% regulation and 1 µV/√Hz noise.

FAQ
What is the Zener voltage tolerance of JANTX1N4108D-1/TR?
JANTX1N4108D-1/TR has a nominal Zener voltage of 14.0 V with ±1% tolerance, indicated by the "D" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full qualified operating temperature range when derated per MIL-PRF-19500/435 requirements. The JANTX1N4108D-1/TR maintains this specification under military screening conditions.
Is JANTX1N4108D-1/TR RoHS compliant?
JANTX1N4108D-1/TR is not RoHS compliant; the "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions of this family. As a JANTX-level military part, JANTX1N4108D-1/TR uses tin-lead plating per MIL-STD-750 method 2026 and does not meet EU RoHS Directive 2011/65/EU restrictions on lead content. The JANTX1N4108D-1/TR remains fully compliant with applicable military specifications.
What is the maximum Zener current IZM for JANTX1N4108D-1/TR?
The maximum Zener current IZM for JANTX1N4108D-1/TR is 40 mA, as specified in the Electrical Characteristics table on page 3 of Microsemi T4-LDS-0245-2. This value corresponds to the rated average power dissipation of 500 mW at 25 °C lead temperature, and assumes operation within the linear derating curve that reduces allowable power to zero at +175 °C junction temperature. Exceeding 40 mA risks thermal runaway in the JANTX1N4108D-1/TR.
Does JANTX1N4108D-1/TR have radiation hardness certification?
Yes, JANTX1N4108D-1/TR is inherently radiation hard per Microsemi MicroNote 050, with documented tolerance to total ionizing dose (TID) up to 100 krad(Si). This characteristic arises from its metallurgically bonded glass construction and is validated across the entire 1N4099–1N4135 family. Radiation performance data for the JANTX1N4108D-1/TR is included in Microsemi's qualified reliability reports supporting MIL-PRF-19500/435 compliance.
What package type does JANTX1N4108D-1/TR use?
JANTX1N4108D-1/TR uses the DO-35 (also designated DO-204AH) axial-leaded, hermetically sealed glass package. Dimensions conform to Microsemi's Package Dimensions drawing on page 5 of T4-LDS-0245-2, with body diameter 1.42–2.29 mm and overall length 25.4–38.1 mm. The "TR" suffix indicates tape-and-reel packaging per EIA-296, and the cathode is marked by a single black band on the JANTX1N4108D-1/TR glass body.
