Product details
Overview
JANTXV1N4615C-1/TR from Microsemi is a 2.0 V, ±2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power conditioning circuits.
For engineers reviewing the JANTXV1N4615C-1/TR datasheet, JANTXV1N4615C-1/TR pinout, JANTXV1N4615C-1/TR application, or JANTXV1N4615C-1/TR equivalent, this part delivers precise low-voltage reference stability with 1250 Ω dynamic impedance at 250 mA test current, -0.075 %/°C temperature coefficient, and 1 μV/√Hz noise density - critical for analog sensor biasing and precision supply monitoring.
Technical Context
This device operates as a reverse-biased voltage regulator with cathode-band polarity marking, requiring banded end to be held positive relative to anode for Zener conduction. Its internal metallurgical bond ensures mechanical robustness under thermal cycling and radiation exposure.
It exhibits a sharp breakdown knee at IZK = 250 mA, with maximum reverse leakage IR ≤ 2.5 μA at VR = 1.0 V and dynamic impedance ZZT = 1250 Ω measured at 10% rms modulation of IZT. Thermal resistance junction-to-lead is 250 °C/W at 10 mm lead length.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 2.0 V ±2% at 250 mA - enables stable low-voltage reference generation with tight tolerance for calibration-critical circuits. |
| Power Dissipation PM(AV) | 500 mW at TC = 25 °C - supports continuous regulation in compact through-hole designs without forced cooling. |
| Dynamic Impedance ZZT | 1250 Ω at IZT = 250 mA - limits output voltage variation under load transients in feedback-sensing applications. |
| Temperature Coefficient αVZ | -0.075 %/°C - ensures predictable, monotonic drift over -65 to +175 °C operating range for space-grade systems. |
| Noise Density ND | 1 μV/√Hz - minimizes added noise in precision analog front-ends such as instrumentation amplifiers and ADC references. |
| Reverse Leakage IR | ≤2.5 μA at VR = 1.0 V - guarantees low standby current in always-on bias networks and low-power supervisory circuits. |
| Junction Temperature Range | -65 to +175 °C - validated for extended operation in avionics, missile guidance, and downhole electronics environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4615-1/TR | Same 2.0 V nominal, but ±5% tolerance instead of ±2%. | Acceptable where tighter regulation not required; lower cost for non-critical biasing. | Select when budget constraints outweigh need for 2% precision in non-calibrated subsystems. |
| 1N4615US-1/TR | Same electrical specs, but in surface-mount DO-213AA package (no axial leads). | Required for automated SMT assembly; unsuitable for through-hole prototyping or repair. | Choose for high-volume PCB production where reflow compatibility and board space savings are prioritized. |
Compared with JANTXV1N4615C-1/TR, the JANTXV1N4615-1/TR trades tolerance for cost while retaining identical qualification and thermal performance; the 1N4615US-1/TR replaces axial mounting with SMT compatibility but requires layout redesign and lacks JANTXV-level screening.

FAQ
What is the Zener voltage tolerance of JANTXV1N4615C-1/TR?
JANTXV1N4615C-1/TR has a nominal Zener voltage of 2.0 V with a ±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 remains stable across the full -65 to +175 °C junction temperature range due to its negative temperature coefficient of -0.075 %/°C.
Is JANTXV1N4615C-1/TR RoHS compliant?
No, JANTXV1N4615C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (suffix "e3") are available only for commercial-grade variants, not for JANTXV-qualified parts. The JANTXV1N4615C-1/TR uses traditional tin-lead plating on its axial leads to meet MIL-STD-750 solderability requirements and ensure long-term reliability in harsh environments.
What is the maximum Zener current IZM for JANTXV1N4615C-1/TR?
The maximum Zener current IZM for JANTXV1N4615C-1/TR is 110.0 mA, derived from its 500 mW power rating and 2.0 V nominal Zener voltage (IZM = PM(AV)/VZ). This value assumes operation at 25 °C lead temperature; derating begins linearly at 50 °C and reaches zero at 175 °C per Figure 2 in the official datasheet.
How is polarity marked on JANTXV1N4615C-1/TR?
JANTXV1N4615C-1/TR uses a single black band on the glass body to indicate the cathode terminal. During Zener regulation, the banded end must be held positive relative to the unbanded (anode) end. This polarity marking is consistent across all DO-35 packaged devices in the 1N4614–1N4627 series and is verified per MIL-STD-750 method 2026 for solderability and visual identification.
What packaging option does JANTXV1N4615C-1/TR use?
JANTXV1N4615C-1/TR is supplied in tape-and-reel format per EIA-296 standard, as indicated by the "TR" suffix. It uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package with approximate weight of 0.2 grams and lead length between 25.4 mm and 38.1 mm, optimized for manual or wave-solder assembly in high-reliability PCBs.
