Product details
Overview
JANTXV1N4100C-1 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 JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4100C-1 datasheet, JANTXV1N4100C-1 pinout, JANTXV1N4100C-1 application, or JANTXV1N4100C-1 equivalent, key selection factors include its 7.5 V nominal Zener voltage at 250 mA test current, 200 Ω dynamic impedance, 5.7 mA maximum Zener current, ±2% voltage tolerance, and -65 °C to +175 °C operating temperature range.
Technical Context
This device operates as a precision shunt voltage regulator with cathode-banded polarity, requiring reverse-bias operation where the banded end is positive relative to the anode. Its internal metallurgical bond ensures stable breakdown characteristics and low noise density (1 μV/√Hz typical at 7.5 V).
It exhibits a +0.065 %/°C temperature coefficient of Zener voltage and maintains regulation across wide current ranges (up to 5.7 mA), with thermal resistance junction-to-lead of 250 °C/W when mounted with 3/8″ lead length - critical for thermal design in sealed military enclosures.
Key Specifications

| Zener Tolerance | ±2% - tighter than standard 5% parts, enabling higher accuracy in feedback loops |
| Power Dissipation | 500 mW at 25 °C - derates linearly to zero at 175 °C, limiting usable ambient range |
| Dynamic Impedance ZZT | 200 Ω - determines output voltage variation under load current changes |
| Max Reverse Current IR | 0.5 µA at 5.7 V - ensures minimal leakage in high-impedance bias networks |
| Temp Coefficient αVZ | +0.065 %/°C - quantifies drift magnitude over temperature for stability analysis |
| Noise Density | 1 µV/√Hz - enables low-noise voltage references in analog signal chains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4100US-1 | Same 7.5 V, ±2%, DO-213AA surface-mount package; no axial leads; RoHS-compliant only | Used where board space is constrained and reflow soldering is required instead of through-hole mounting | Select when transitioning from through-hole to SMT assembly or when hermetic SMT packaging is mandated |
| JANTXV1N4101C-1 | 8.2 V nominal Zener voltage; identical package, qualification, and tolerance; +0.070 %/°C TC | Applied where higher reference voltage is needed for comparator thresholds or op-amp biasing | Choose when system-level calibration requires 8.2 V instead of 7.5 V, with no change to mechanical or reliability requirements |
Compared with JANTXV1N4100C-1, the 1N4100US-1 offers identical electrical specs but eliminates axial leads for SMT compatibility, while JANTXV1N4101C-1 shifts the regulation point upward by 0.7 V - both preserve MIL-PRF-19500/435 JANTXV qualification and low-noise performance.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4100C-1?
JANTXV1N4100C-1 has a nominal Zener voltage of 7.5 V at 250 mA test current with a tight ±2% tolerance. This specification is verified per MIL-PRF-19500/435 and applies across the full -65 °C to +175 °C junction temperature range, making JANTXV1N4100C-1 suitable for high-accuracy reference applications in extreme environments.
Is JANTXV1N4100C-1 RoHS compliant?
No, JANTXV1N4100C-1 is not RoHS compliant. The "e3" suffix denotes RoHS compliance, which is only available on commercial-grade versions (e.g., 1N4100C-1e3). JANTXV1N4100C-1 uses traditional tin-lead plating per MIL-STD-750 and is intended for legacy and high-reliability military/aerospace programs where leaded finishes are required.
What is the maximum Zener current rating for JANTXV1N4100C-1?
The maximum Zener current (IZM) for JANTXV1N4100C-1 is 5.7 mA at 25 °C ambient, derived from its 500 mW power rating and 7.5 V Zener voltage. This value decreases with rising temperature due to linear derating starting at 50 °C, reaching zero at 175 °C - a critical constraint for thermal design in sealed enclosures using JANTXV1N4100C-1.
How is polarity marked on JANTXV1N4100C-1?
JANTXV1N4100C-1 uses a cathode band for polarity identification: the banded end is the cathode and must be held positive relative to the anode for proper Zener regulation. This marking conforms to JEDEC standards and is visible on the glass DO-35 body; incorrect orientation will result in forward conduction rather than voltage regulation.
What is the temperature coefficient of JANTXV1N4100C-1?
JANTXV1N4100C-1 has a temperature coefficient (αVZ) of +0.065 %/°C, meaning its Zener voltage increases by approximately 4.88 mV per degree Celsius rise in junction temperature. This positive coefficient is typical for 7.5 V Zeners and must be factored into system-level accuracy budgets for JANTXV1N4100C-1 in wide-temperature applications.
