Product details
Overview
JANTXV1N4099C-1 from Microsemi is a 500 mW, 6.8 V metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANTXV level per MIL-PRF-19500/435, with ±2% Zener voltage tolerance, 200 Ω max dynamic impedance at 250 mA, and 40 µV/√Hz noise density - used for precision voltage regulation in military-grade power supply reference circuits.
For engineers reviewing the JANTXV1N4099C-1 datasheet, JANTXV1N4099C-1 pinout, JANTXV1N4099C-1 application, or JANTXV1N4099C-1 equivalent, key selection criteria include Zener voltage tolerance (±2%), junction temperature range (–65 °C to +175 °C), thermal resistance (250 °C/W junction-to-lead), RoHS compliance status, and MIL-qualified reliability level.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 6.8 V at 250 mA test current, exhibiting +0.060 %/°C temperature coefficient and 200 Ω maximum dynamic impedance (ZZT). Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for high-reliability environments, JANTXV1N4099C-1 maintains regulation across wide current ranges (IZK to IZM = 5.2 mA to 70 mA) and supports operation up to 175 °C junction temperature, with hermetic glass encapsulation and tin-lead plating compliant with MIL-STD-750 method 2026.
Key Specifications

|---|---|
| Zener Voltage (VZ) | 6.8 V ±2% at 250 mA - defines precise regulation point for reference design |
| Power Dissipation | 500 mW at 25 °C, linearly derated to zero at 175 °C - sets thermal layout constraints |
| Dynamic Impedance (ZZT) | ≤200 Ω at 250 mA - determines output voltage stability under load transients |
| Noise Density | 40 µV/√Hz at 1 kHz–3 kHz - critical for low-noise analog reference applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4099UR-1 | Same 6.8 V ±2% spec, but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy board repair | Select when automated SMT production and space-constrained layouts are priorities |
| JANTXV1N4100C-1 | 7.5 V nominal Zener voltage (±2%), identical package, qualification, and thermal specs | Used where 7.5 V reference is required instead of 6.8 V; not interchangeable without circuit redesign | Choose only if system-level voltage margin analysis confirms 7.5 V compatibility |
Compared with JANTXV1N4099C-1, the 1N4099UR-1 offers identical electrical performance in a surface-mount form factor, while JANTXV1N4100C-1 provides a higher-voltage alternative within the same military-qualified family - both require explicit validation for replacement due to voltage or packaging mismatch.

FAQ
What is the Zener voltage tolerance of JANTXV1N4099C-1?
JANTXV1N4099C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This means its measured VZ at 250 mA test current falls within 6.664 V to 6.936 V at 25 °C. The tighter tolerance reduces calibration overhead in high-accuracy reference designs compared to standard ±5% variants like JANTXV1N4099-1.
Is JANTXV1N4099C-1 RoHS compliant?
No, JANTXV1N4099C-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts, not for JANTXV-qualified devices. JANTXV1N4099C-1 uses traditional tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and reliability under military environmental stresses.
What is the maximum Zener current (IZM) for JANTXV1N4099C-1?
The maximum Zener current IZM for JANTXV1N4099C-1 is 70 mA, derived from its 500 mW power rating and 6.8 V nominal Zener voltage (P = V × I → I = 0.5 W / 6.8 V ≈ 73.5 mA, rounded down to 70 mA per datasheet Table on Page 3). Exceeding this current risks thermal runaway or permanent degradation.
How does the temperature coefficient affect JANTXV1N4099C-1 in real-world operation?
JANTXV1N4099C-1 has a temperature coefficient of +0.060 %/°C, meaning its Zener voltage increases by approximately 4.08 mV per °C rise above 25 °C. Over a –55 °C to +125 °C ambient range, this results in ~±1.02 V total drift - a key constraint for wide-temperature applications requiring sub-1% regulation accuracy without compensation.
Can JANTXV1N4099C-1 be used in surface-mount designs?
No, JANTXV1N4099C-1 is packaged in the axial-leaded DO-35 (DO-204AH) glass case and is not suitable for surface-mount assembly. For SMT-compatible equivalents, Microsemi offers the 1N4099UR-1 in DO-213AA package - same electrical specs but different mechanical form factor. Direct substitution requires PCB layout revision and requalification.
