Product details
Overview
JANTXV1N4129D-1/TR from Microsemi is a 62 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power conditioning circuits.
For engineers reviewing the JANTXV1N4129D-1/TR datasheet, JANTXV1N4129D-1/TR pinout, JANTXV1N4129D-1/TR application, or JANTXV1N4129D-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, noise density, dynamic impedance, and military qualification status - critical for precision reference and radiation-hardened design validation.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 62 V at 250 mA test current, exhibiting a +0.100 %/°C temperature coefficient and 500 Ω maximum dynamic impedance (ZZT) at IZT. Its metallurgical bond construction ensures stable regulation across -65 °C to +175 °C junction temperature range.
Designed for high-reliability environments, JANTXV1N4129D-1/TR meets MIL-PRF-19500/435 requirements at JANTXV level, features hermetically sealed DO-35 glass packaging, and delivers 1 μV/√Hz typical noise density below 6.8 V - though at 62 V, noise density remains ≤40 μV/√Hz per specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 62 V ±1% at 250 mA - enables precise mid-range voltage reference in regulated power supplies. |
| Power Dissipation | 500 mW at 25 °C - supports stable operation up to 175 °C with linear derating from 50 °C. |
| Dynamic Impedance (ZZT) | 500 Ω max at IZT - ensures low AC impedance for ripple rejection in analog reference circuits. |
| Temperature Coefficient (αVZ) | +0.100 %/°C - provides predictable, monotonic drift for thermal compensation schemes. |
| Noise Density (ND) | ≤40 μV/√Hz - maintains low broadband noise in precision instrumentation references. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4129US-1TR | Same 62 V, 1% spec but in surface-mount DO-213AA package; no axial leads. | Used where PCB real estate is constrained and reflow assembly is preferred over through-hole. | Select when automated SMT placement is required and thermal mass constraints allow lower peak power handling. |
| JANS1N4129D-1 | Identical electrical specs but qualified to JANS level (highest MIL-PRF-19500 screening tier); higher cost and longer lead time. | Required for manned spacecraft and nuclear command systems where full JANS screening is mandated. | Choose only when program documentation explicitly requires JANS-level qualification - not for general JANTXV use cases. |
Compared with JANTXV1N4129D-1/TR, the 1N4129US-1TR offers identical regulation performance in a compact SMT form factor but sacrifices lead-to-lead thermal dissipation capability, while JANS1N4129D-1 adds extreme reliability screening without altering electrical behavior - making both alternatives situational rather than drop-in replacements.

FAQ
What is the Zener voltage tolerance for JANTXV1N4129D-1/TR?
JANTXV1N4129D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number per Microsemi's nomenclature. This is tighter than the standard ±5% (blank suffix) or ±2% ("C" suffix) options, enabling higher accuracy in precision reference applications without external trimming.
Is JANTXV1N4129D-1/TR RoHS compliant?
No, JANTXV1N4129D-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts, not for JAN, JANTX, JANTXV, or JANS qualified devices like JANTXV1N4129D-1/TR.
What does the "TR" suffix indicate in JANTXV1N4129D-1/TR?
The "TR" suffix in JANTXV1N4129D-1/TR indicates tape-and-reel packaging per EIA-296 standard, intended for automated pick-and-place assembly. It does not affect electrical specifications or qualification level - JANTXV1N4129D-1/TR retains full JANTXV MIL-PRF-19500/435 compliance regardless of packaging format.
What is the maximum Zener current (IZM) for JANTXV1N4129D-1/TR?
The maximum Zener current (IZM) for JANTXV1N4129D-1/TR is 47.1 mA, calculated from its 500 mW power rating and 62 V nominal Zener voltage (IZM = PM(AV)/VZ). This value assumes operation at 25 °C; derating applies above 50 °C per the published power curve.
How is polarity marked on JANTXV1N4129D-1/TR?
JANTXV1N4129D-1/TR uses a cathode band marking on the glass DO-35 body - the banded end is the cathode and must be held at a more positive potential than the anode to achieve Zener breakdown regulation. This polarity is consistent across all 1N4099–1N4135 series devices.
