Product details
Overview
JANTXV1N4625C-1 from Microsemi is a 500 mW, 5.1 V Zener diode in DO-35 glass package, qualified to JANTXV level per MIL-PRF-19500/435, with 2% voltage tolerance, 1500 Ω dynamic impedance at 250 mA test current, and ±0.045%/°C to +0.030%/°C temperature coefficient - used for precision voltage regulation in military-grade power supply reference circuits.
For engineers reviewing the JANTXV1N4625C-1 datasheet, JANTXV1N4625C-1 pinout, JANTXV1N4625C-1 application, or JANTXV1N4625C-1 equivalent, this page delivers verified electrical parameters, mil-spec qualification status, thermal derating behavior, noise density (2 µV/√Hz), and direct alternative part comparisons - all confirmed from Microsemi's official T4-LDS-0245-2 Rev. 1 specification.
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded construction ensuring high reliability under thermal cycling and radiation exposure. Its Zener voltage is specified at 5.1 V ±2% with IZT = 250 mA, and exhibits low noise density (2 µV/√Hz) and stable regulation across -65°C to +175°C junction temperature range.
The DO-35 axial-leaded glass package enables hermetic sealing and supports lead-soldering per MIL-STD-750 Method 2026. Thermal resistance is 250°C/W junction-to-lead (at 10 mm lead length), and power dissipation linearly derates from 500 mW at 25°C ambient to zero at 175°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 5.1 V ±2% at IZT = 250 mA - defines precise regulation point for feedback loops and reference rails. |
| Power Dissipation | 500 mW @ TL = 25°C - sets maximum continuous DC power before thermal derating begins at 50°C. |
| Dynamic Impedance ZZT | 1500 Ω @ IZT = 250 mA - determines output voltage stability under load current variation. |
| Noise Density | 2 µV/√Hz @ IZT = 250 mA - critical for low-noise analog references and precision instrumentation. |
| Temp Coefficient αVZ | -0.045%/°C to +0.030%/°C - quantifies voltage drift over temperature, enabling compensation design. |
| Reverse Leakage IR | 3.0 µA @ VR = 3.0 V - ensures minimal parasitic current in standby or high-impedance bias networks. |
| Junction Temp Range | -65°C to +175°C - supports operation in aerospace, downhole, and extended-temperature industrial systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4625US-1 | Same 5.1 V, 2% tolerance, but in DO-213AA surface-mount package instead of DO-35. | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or legacy designs. | Select when automated SMT production and space-constrained layouts are priorities. |
| 1N4625-1TR | Commercial-grade (non-mil) version, same 5.1 V/2%, RoHS-compliant e3 finish, tape-and-reel packaging. | Lacks JANTXV screening and radiation hardness; not approved for defense/aerospace deployment. | Select for cost-sensitive industrial or commercial systems where mil-spec is unnecessary. |
Compared with JANTXV1N4625C-1, JANTXV1N4625US-1 offers identical electrical specs in a surface-mount form factor, while 1N4625-1TR provides equivalent regulation performance without military qualification - enabling trade-offs between reliability assurance, assembly method, and procurement cost.

FAQ
What is the Zener voltage tolerance of JANTXV1N4625C-1?
JANTXV1N4625C-1 has a nominal Zener voltage of 5.1 V with a tolerance of ±2%, as indicated by the "C" suffix in its part number per Microsemi's nomenclature. This tolerance is guaranteed under standard test conditions (25°C, IZT = 250 mA) and maintained across the full qualified temperature range due to JANTXV-level screening and metallurgical bond construction.
Is JANTXV1N4625C-1 suitable for high-temperature operation?
Yes, JANTXV1N4625C-1 is rated for junction temperatures from -65°C to +175°C and is qualified per MIL-PRF-19500/435. Its power dissipation linearly derates from 500 mW at 25°C ambient to zero at 175°C, making it suitable for downhole, engine-mounted, and other extended-temperature applications where commercial Zeners fail.
Does JANTXV1N4625C-1 have radiation hardness?
Yes, JANTXV1N4625C-1 exhibits inherent radiation hardness as documented in Microsemi MicroNote 050. This property stems from its metallurgically bonded glass construction and is validated through JANTXV-level qualification testing, supporting use in nuclear monitoring and space-based electronics without additional hardening.
What is the noise performance of JANTXV1N4625C-1?
JANTXV1N4625C-1 delivers a noise density of 2 µV/√Hz at IZT = 250 mA and 25°C, measured in the 1 kHz–3 kHz band. This low-noise characteristic is critical for precision analog applications such as sensor excitation, ADC reference buffers, and RF bias networks where reference noise directly degrades system SNR.
How does the temperature coefficient of JANTXV1N4625C-1 affect regulation accuracy?
JANTXV1N4625C-1 has a temperature coefficient αVZ ranging from -0.045%/°C to +0.030%/°C, meaning its Zener voltage may drift up to ±0.030%/°C near room temperature. This allows predictable compensation in high-accuracy designs and ensures tighter regulation than standard 5% tolerance Zeners across wide thermal excursions.
