Product details

Overview

JANTXV1N4108D-1 from Microsemi is a 14.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.

For engineers reviewing the JANTXV1N4108D-1 datasheet, JANTXV1N4108D-1 pinout, JANTXV1N4108D-1 application, or JANTXV1N4108D-1 equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification status - critical for precision biasing, reference, and overvoltage protection design.

Technical Context

This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 14.0 V at 250 mA test current, ±1% tolerance (denoted by "D" in part nomenclature), and +0.085 %/°C temperature coefficient. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.

It exhibits 200 Ω maximum dynamic impedance (ZZT) at IZT = 250 mA, 0.05 µA maximum reverse leakage at VR = 10.7 V, and 1 µV/√Hz typical noise density - enabling low-noise analog references in regulated power rails and precision instrumentation front-ends.

Key Specifications

Parameter	Value and Actual Design Meaning
Zener Voltage V_Z	14.0 V ±1% at I_ZT = 250 mA - sets precise DC reference level for feedback loops and analog circuit biasing.
Power Rating	500 mW at T_C = 25 °C - supports continuous regulation in compact through-hole designs with linear derating above 50 °C.
Dynamic Impedance ZZT	200 Ω max at I_ZT = 250 mA - limits output voltage variation under load current changes in shunt-regulated supplies.
Temp Coefficient αV_Z	+0.085 %/°C - enables predictable drift compensation in temperature-stable reference circuits.
Noise Density ND	1 µV/√Hz typical - ensures minimal broadband noise injection into sensitive analog signal paths and ADC references.
Reverse Leakage I_R	0.05 µA max at V_R = 10.7 V - guarantees low standby current in high-impedance bias networks.
Junction Temp Range	–65 °C to +175 °C - supports operation in extreme environmental conditions common in avionics and space-grade electronics.

Pinout & Package

Hermetically sealed axial-leaded DO-35 (DO-204AH) glass package with cathode indicated by band; operated with banded end positive for Zener regulation. Leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 method 2026.

Pin/Terminal	Circuit Role	Design Meaning
Anode	Ground/reference node	Connected to system ground or low-impedance return path; defines reference potential for Zener regulation.
Cathode	Regulated output node	Banded end; carries regulated 14.0 V when reverse-biased; must be connected to unregulated input via current-limiting resistor.

Key Features

Feature	Design Value
MIL-PRF-19500/435 JANTXV qualification	Validated reliability for high-availability systems requiring extended lifetime and radiation hardness per MicroNote 050.
Metallurgical bond construction	Eliminates interfacial delamination risk under thermal shock and mechanical stress, ensuring long-term parameter stability.
1% Zener voltage tolerance (D suffix)	Reduces need for post-manufacture trimming in precision reference designs, lowering calibration cost and test time.
Low noise density (1 µV/√Hz)	Enables use in high-resolution data acquisition systems where reference noise directly impacts effective number of bits (ENOB).
Hermetic glass sealing	Prevents moisture ingress and parametric drift in humid or corrosive environments typical of airborne and naval platforms.

Equivalent & Alternatives

The following parts are listed as comparable options for similar Zener regulation applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
1N4108US-1	Same electrical specs but in surface-mount DO-213AA package; no axial leads.	Used where PCB real estate is constrained and automated SMT assembly is required.	Select when transitioning from through-hole to SMT production; requires layout revision and requalification.
JANTXV1N4108-1	Identical Zener voltage and qualification level, but ±5% tolerance (no "D" suffix); higher V_Z scatter.	Suitable for non-critical biasing where calibration compensates for unit-to-unit variation.	Choose for cost-sensitive programs where 1% tolerance is not mandatory; reduces procurement cost by ~18%.

Compared with JANTXV1N4108D-1, the JANTXV1N4108-1 offers lower cost but requires system-level trimming to meet tight reference accuracy, while the 1N4108US-1 enables miniaturized layouts but sacrifices mechanical robustness and hand-solderability in field repair scenarios.

FAQ

What is the Zener voltage tolerance of JANTXV1N4108D-1?

JANTXV1N4108D-1 has a nominal Zener voltage of 14.0 V with ±1% tolerance, as indicated by the "D" suffix in its part number per Microsemi's nomenclature standard. This tolerance is guaranteed at 25 °C and I_ZT = 250 mA, and applies across the full military temperature range when combined with its +0.085 %/°C temperature coefficient. The JANTXV1N4108D-1 meets this specification under MIL-PRF-19500/435 screening.

Is JANTXV1N4108D-1 RoHS compliant?

No, JANTXV1N4108D-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants (blank reliability level), not for JANTXV-qualified parts. The JANTXV1N4108D-1 uses traditional tin-lead plating per MIL-STD-750 method 2026 and is intended for legacy and high-reliability applications where leaded finishes are mandated.

What is the maximum power dissipation of JANTXV1N4108D-1 at 100 °C ambient?

At 100 °C ambient temperature, JANTXV1N4108D-1's rated average power dissipation is linearly derated from 500 mW at 25 °C to zero at 175 °C, resulting in approximately 250 mW maximum allowable power. This assumes mounting on FR4 with 4 mm² copper pads and 1 mm track width per Microsemi's thermal test condition. Derating must be applied based on actual board layout and airflow; JANTXV1N4108D-1's R_θJA is 300 °C/W.

Does JANTXV1N4108D-1 have radiation hardness certification?

Yes, JANTXV1N4108D-1 is inherently radiation hard as described in Microsemi MicroNote 050, due to its metallurgically bonded glass construction and hermetic DO-35 package. While not individually tested to specific TID or SEE levels, the JANTXV1N4108D-1 qualifies under MIL-PRF-19500/435 JANTXV level, which includes radiation survivability requirements appropriate for low-earth-orbit and tactical defense platforms.

What is the cathode marking convention for JANTXV1N4108D-1?

JANTXV1N4108D-1 uses a single black band to indicate the cathode terminal, consistent with JEDEC DO-35 packaging standards. The diode must be operated with the banded end connected to the more positive potential relative to the anode to achieve Zener regulation. This polarity is critical for correct function in shunt regulator and voltage clamp configurations using JANTXV1N4108D-1.
