Product details
Overview
JANTXV1N4100C-1/TR from Microsemi is a 500 mW, 7.5 V ±2% tolerance, 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 JANTXV1N4100C-1/TR datasheet, JANTXV1N4100C-1/TR pinout, JANTXV1N4100C-1/TR application, or JANTXV1N4100C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), max noise density (1 µV/√Hz), dynamic impedance (200 Ω), temperature coefficient (+0.065 %/°C), and JANTXV-level qualification for extended temperature operation (-65 °C to +175 °C).
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 7.5 V at 250 mA test current, exhibiting low dynamic impedance (200 Ω) and minimal capacitance (typical 42 pF). Its metallurgical bond construction ensures stable regulation across wide current and temperature ranges.
The JANTXV1N4100C-1/TR is designed for operation with cathode-banded end positive relative to anode, supporting reverse-biased breakdown regulation. It delivers specified performance under MIL-PRF-19500/435 JANTXV screening, including hermetic glass sealing and non-ESD-sensitive behavior per MIL-STD-750 Method 1020.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4100UR-1 | Same electrical specs, but in DO-213AA surface-mount package instead of DO-35 axial lead | Required for automated SMT assembly; lacks axial mounting flexibility | Select when board space is constrained and reflow compatibility is mandatory |
| 1N4100US-1 | Commercial-grade (non-mil-qualified), same 7.5 V ±5% tolerance, no JANTXV screening | Suitable only for non-mission-critical industrial use; not rated for radiation or extreme thermal cycling | Select for cost-sensitive prototyping where MIL-spec reliability is unnecessary |
Compared with JANTXV1N4100C-1/TR, JANTXV1N4100UR-1 offers identical regulation performance in a surface-mount form factor ideal for high-density PCBs, while 1N4100US-1 provides a lower-cost commercial alternative lacking military screening-neither is pin-compatible due to differing packages and qualification levels.

FAQ
What is the Zener voltage tolerance of JANTXV1N4100C-1/TR?
JANTXV1N4100C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its nomenclature. This means its nominal 7.5 V Zener voltage is guaranteed between 7.35 V and 7.65 V at 250 mA test current and 25 °C, enabling tighter regulation than standard ±5% variants like JANTXV1N4100-1/TR.
Is JANTXV1N4100C-1/TR suitable for high-temperature operation?
Yes, JANTXV1N4100C-1/TR is rated for junction temperatures from -65 °C to +175 °C and qualified to MIL-PRF-19500/435 JANTXV level. Its metallurgically bonded construction and hermetic DO-35 package ensure stable 7.5 V regulation across this full range, making it appropriate for engine-mounted avionics and downhole oilfield electronics.
What does the "TR" suffix indicate in JANTXV1N4100C-1/TR?
The "TR" suffix in JANTXV1N4100C-1/TR indicates tape-and-reel packaging per EIA-296 standard, optimized for automated pick-and-place assembly. This format ensures consistent orientation (cathode band aligned), controlled quantity per reel, and ESD-safe handling-critical for high-mix military PCB manufacturing lines.
How does the noise performance of JANTXV1N4100C-1/TR compare to lower-voltage Zeners?
JANTXV1N4100C-1/TR exhibits a maximum noise density of 1 µV/√Hz at 7.5 V, consistent with the trend described in Microsemi's documentation where noise falls rapidly below 6.8 V. This low-noise characteristic makes JANTXV1N4100C-1/TR preferable over higher-voltage Zeners (e.g., 12 V or 24 V) in precision analog reference designs where spectral purity is essential.
Can JANTXV1N4100C-1/TR be used as a replacement for commercial 1N4100 diodes?
JANTXV1N4100C-1/TR is not a drop-in replacement for commercial 1N4100 diodes due to its tighter ±2% tolerance, JANTXV qualification, and different screening. While electrically compatible in basic regulation circuits, substituting it requires verifying that system-level reliability, thermal derating, and procurement compliance requirements align with MIL-spec sourcing-not just electrical equivalence.
