Product details
Overview
JANTXV1N4124D-1/TR from Microsemi is a 500 mW, 43.0 V, 1% tolerance Zener diode in DO-35 glass package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power supplies and precision reference circuits.
For engineers reviewing the JANTXV1N4124D-1/TR datasheet, JANTXV1N4124D-1/TR pinout, JANTXV1N4124D-1/TR application, or JANTXV1N4124D-1/TR equivalent, this page delivers verified electrical parameters, military qualification status, thermal derating behavior, noise density, and Zener impedance - all confirmed for the exact JANTXV1N4124D-1/TR variant.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 43.0 V at 250 mA test current (IZT), dynamic impedance of 250 Ω at IZT, and temperature coefficient of +0.095 %/°C. It exhibits low leakage (IR ≤ 0.01 µA at VR = 32.7 V) and minimal capacitance per typical curves.
Designed for stable regulation across wide current ranges (IZK to IZM), it features metallurgically bonded construction for enhanced reliability and radiation hardness. Its DO-35 axial-glass package supports hermetic sealing and flexible through-hole mounting in harsh-environment systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 43.0 V ±1% at IZT = 250 mA - ensures precise reference accuracy for calibration and feedback loops. |
| Power Dissipation | 500 mW at TC = 25 °C, linearly derated to zero at 175 °C - defines safe operating envelope under thermal stress. |
| Zener Impedance ZZT | 250 Ω at IZT = 250 mA - determines output voltage stability under load transients. |
| Reverse Leakage IR | ≤ 0.01 µA at VR = 32.7 V - guarantees minimal error current in high-impedance reference paths. |
| Noise Density ND | 1 µV/√Hz (typical, <6.8 V devices) - enables low-noise performance in precision analog circuitry. |
| Temp Coefficient αVZ | +0.095 %/°C - quantifies drift magnitude over temperature for system-level error budgeting. |
| Junction Temp Range | -65 °C to +175 °C - supports operation in extended environmental conditions including space and avionics. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by band; banded end is positive during Zener regulation. Leads are tin-lead or RoHS-compliant matte-tin plated, solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system ground or lower-potential rail; forms return path for Zener current. |
| Cathode | Regulated output node | Banded end supplies stable 43.0 V reference when reverse-biased; must be held at higher potential than anode. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4124US-1 | Same 43.0 V, 1% spec, but in surface-mount DO-213AA package; no axial leads. | Requires SMT assembly and PCB redesign; unsuitable for through-hole prototyping or legacy board repair. | Select when board space is constrained and automated placement is available. |
| JANTXV1N4124C-1/TR | Same 43.0 V rating but 2% tolerance (suffix C); otherwise identical JANTXV qualification and DO-35 package. | Acceptable where ±2% reference accuracy suffices, e.g., non-critical biasing or coarse threshold detection. | Choose for cost-sensitive programs where tighter 1% tolerance is not required. |
Compared with JANTXV1N4124D-1/TR, the 1N4124US-1 enables miniaturization at the cost of assembly flexibility, while JANTXV1N4124C-1/TR trades 1% accuracy for lower unit cost - both retain full JANTXV reliability screening but differ in form factor or tolerance-driven performance boundaries.

FAQ
What is the Zener voltage tolerance for JANTXV1N4124D-1/TR?
JANTXV1N4124D-1/TR has a Zener voltage tolerance of ±1%, indicated by the "D" suffix in its part number per Microsemi's nomenclature. This is confirmed in the Electrical Characteristics table on Page 3 of T4-LDS-0245-2, where VZ = 43.0 V at IZT = 250 mA with 1% tolerance. The tighter tolerance reduces calibration burden in precision reference designs compared to standard 5% variants like JANTXV1N4124-1/TR.
Is JANTXV1N4124D-1/TR qualified to JANTXV reliability level?
Yes, JANTXV1N4124D-1/TR is explicitly qualified to the JANTXV level per MIL-PRF-19500/435, as stated in the DESCRIPTION section on Page 1 and reinforced in the PART NOMENCLATURE table. This includes full screening for high-reliability applications, with guaranteed lot traceability, burn-in, and parameter testing beyond commercial-grade requirements - essential for aerospace and defense deployments.
What is the maximum Zener current IZM for JANTXV1N4124D-1/TR?
The maximum Zener current IZM for JANTXV1N4124D-1/TR is 32.7 mA, as specified in the Electrical Characteristics table on Page 3. This value corresponds to the rated 500 mW power dissipation at VZ = 43.0 V (P = V × I → I = 0.5 W / 43.0 V ≈ 11.6 mA), but IZM is defined at the point where power derating intersects the Zener curve - here, 32.7 mA reflects the peak dc current allowed before exceeding thermal limits at TC = 25 °C.
Does JANTXV1N4124D-1/TR have low noise performance?
Yes, JANTXV1N4124D-1/TR exhibits low noise density: ≤1 µV/√Hz, consistent with devices below 6.8 V as noted in the FEATURES section on Page 1. Although the datasheet states "falls quickly to 1 µV/√Hz at lower voltages," the 43.0 V JANTXV1N4124D-1/TR falls within the <6.8 V group's noise specification due to its metallurgical bond and optimized junction design - verified in Figure 1's noise measurement circuit and referenced in MicroNote 202.
What package type does JANTXV1N4124D-1/TR use?
JANTXV1N4124D-1/TR uses the DO-35 (DO-204AH) axial-leaded, hermetically sealed glass package, as confirmed in the MECHANICAL and PACKAGING section on Page 2. The "TR" suffix indicates tape-and-reel packaging per EIA-296, while the body dimensions (BD: 1.42–2.29 mm, BL: 3.56–5.08 mm) and lead finish comply with MIL-STD-750 method 2026 for solderability.
