Product details
Overview
JANTX1N4100C-1 from Microsemi is a 500 mW, 7.5 V ±2% tolerance 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 JANTX1N4100C-1 datasheet, JANTX1N4100C-1 pinout, JANTX1N4100C-1 application, or JANTX1N4100C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), dynamic impedance (200 Ω @ 250 mA), noise density (40 µV/√Hz), and military-grade thermal derating (0 W at 175 °C).
Technical Context
This device operates as a precision shunt voltage regulator with cathode-banded polarity, requiring reverse bias (banded end positive) for Zener conduction. Its metallurgical bond ensures stable junction behavior under thermal cycling and radiation exposure.
It delivers regulated 7.5 V output across 5.7–40 mA operating current range, with temperature coefficient of +0.065 %/°C and maximum reverse leakage of 1.0 µA at 5.7 V, enabling stable reference generation in analog circuits and feedback loops.
Key Specifications

|---|---|
| Zener Voltage VZ | 7.5 V ±2% at 250 mA - defines precise regulation point for feedback networks and reference circuits |
| Power Dissipation | 500 mW @ 25 °C, linearly derated to zero at 175 °C - sets thermal design margin for PCB layout and heatsinking |
| Dynamic Impedance ZZT | 200 Ω @ 250 mA - determines regulation stability under load transients and ripple rejection capability |
| Noise Density ND | 40 µV/√Hz @ 250 mA - limits voltage reference noise floor in precision ADCs and sensor interfaces |
| Reverse Leakage IR | 1.0 µA @ 5.7 V - ensures low quiescent current in standby-mode power monitors and battery-backed systems |
| Temp Coefficient αVZ | +0.065 %/°C - enables predictable drift compensation in wide-temperature-range instrumentation |
| Junction Temp Range | –65 to +175 °C - supports operation in harsh environments including space-grade and engine-control applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4100C-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 system FMEA mandates enhanced reliability beyond JANTX baseline |

FAQ
What is the Zener voltage tolerance for JANTX1N4100C-1?
JANTX1N4100C-1 has a nominal Zener voltage of 7.5 V with ±2% tolerance, as indicated by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full military temperature range when used within its derated power envelope.
Is JANTX1N4100C-1 RoHS compliant?
No, JANTX1N4100C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants-not for JAN, JANTX, JANTXV, or JANS levels. JANTX1N4100C-1 uses traditional tin-lead plating per MIL-STD-750.
What is the maximum Zener current IZM for JANTX1N4100C-1?
The maximum Zener current IZM for JANTX1N4100C-1 is 40 mA, derived from its 500 mW power rating and 7.5 V Zener voltage (P = V × I → I = 0.5 W / 7.5 V ≈ 66.7 mA), but limited by thermal resistance and derating curves to 40 mA at 25 °C to ensure junction temperature remains within –65 to +175 °C limits.
Does JANTX1N4100C-1 have radiation hardness specifications?
Yes, JANTX1N4100C-1 is inherently radiation hard as documented in Microsemi MicroNote 050. Its metallurgically bonded structure and hermetic DO-35 package provide tolerance to total ionizing dose (TID) up to 100 krad(Si), making it suitable for low-earth orbit satellite power systems without additional shielding.
How is polarity marked on JANTX1N4100C-1?
JANTX1N4100C-1 uses a single cathode band on the glass body to indicate polarity: the banded end is the cathode and must be held at a higher potential than the non-banded (anode) end for proper Zener regulation. This marking complies with JEDEC standards and is visible under standard visual inspection.
