Product details
Overview
JANTXV1N4134C-1/TR from Microsemi is a 500 mW, 91 V, ±2% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4134C-1/TR datasheet, JANTXV1N4134C-1/TR pinout, JANTXV1N4134C-1/TR application, or JANTXV1N4134C-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification details critical for precision reference and radiation-hardened designs.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 91 V at 250 mA test current, exhibiting a +0.100 %/°C temperature coefficient and 1200 Ω dynamic impedance (ZZT) at IZT. Its metallurgical bond construction ensures stable regulation across wide current and temperature ranges.
Designed for high-reliability environments, JANTXV1N4134C-1/TR meets MIL-PRF-19500/435 JANTXV requirements, features hermetically sealed DO-35 packaging, and delivers low noise density (1 µV/√Hz typical) below 10 V - though at 91 V, noise is not specified per datasheet, consistent with series behavior where ND falls rapidly above 6.8 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage (VZ) | 91 V ±2% at 250 mA - defines precise regulation point for high-voltage reference circuits |
| Power Dissipation | 500 mW at 25 °C - sets maximum continuous thermal load before derating begins at 50 °C |
| Dynamic Impedance (ZZT) | 1200 Ω at 250 mA - indicates voltage stability under varying load current near regulation knee |
| Reverse Leakage (IR) | ≤10 µA at 73 V - ensures minimal parasitic current in off-state bias networks |
| Temp. Coefficient (αVZ) | +0.100 %/°C - quantifies voltage drift with ambient temperature change in operational environment |
| Max Zener Current (IZM) | 69.2 mA - derived from 500 mW rating; limits safe DC operating current at full voltage |
| Junction Temp. Range | –65 to +175 °C - supports operation in extreme aerospace and downhole industrial conditions |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by band; banded end is positive during Zener regulation. Hermetically sealed, tin-lead plated leads solderable per MIL-STD-750 method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4134US-1 | Same 91 V ±2%, but in surface-mount DO-213AA package; no axial leads | Requires PCB re-layout for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when automated assembly, board space constraints, or vibration resistance outweigh lead-forming flexibility |
| JANTXV1N4134D-1/TR | Identical 91 V rating and JANTXV qualification, but ±1% tolerance (D suffix) instead of ±2% | Higher initial accuracy enables tighter system-level voltage tolerances without trimming | Select when absolute reference accuracy dominates cost and availability considerations |
Compared with JANTXV1N4134C-1/TR, 1N4134US-1 trades axial-mount versatility for SMT manufacturability, while JANTXV1N4134D-1/TR improves initial tolerance at the expense of higher unit cost and longer lead times - both require explicit validation for radiation or thermal cycling if replacing in flight hardware.

FAQ
What is the Zener voltage tolerance of JANTXV1N4134C-1/TR?
JANTXV1N4134C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number per Microsemi's nomenclature. This means its measured VZ at 250 mA test current falls within 91 V ±1.82 V (89.18 V to 92.82 V) at 25 °C, confirmed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1.
Is JANTXV1N4134C-1/TR RoHS compliant?
No, JANTXV1N4134C-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (e3 suffix) are available only for commercial-grade parts; JANTXV-level devices like JANTXV1N4134C-1/TR use traditional tin-lead plating to meet MIL-STD-750 solderability requirements and are exempt from RoHS under defense procurement waivers.
What is the maximum Zener current (IZM) for JANTXV1N4134C-1/TR?
The maximum Zener current IZM for JANTXV1N4134C-1/TR is 69.2 mA, calculated from its 500 mW power rating and 91 V nominal Zener voltage (P = V × I → I = 0.5 W / 91 V ≈ 0.0055 A). This value is explicitly listed in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1.
Does JANTXV1N4134C-1/TR have a specified noise density (ND)?
No, JANTXV1N4134C-1/TR does not have a published noise density value. The datasheet states max ND is 40 µV/√Hz for 6.8 V and up, falling quickly to 1 µV/√Hz at lower voltages - but no specific ND is given for 91 V devices like JANTXV1N4134C-1/TR, consistent with measurement limitations at high Zener voltages.
What does the "TR" suffix mean in JANTXV1N4134C-1/TR?
"TR" stands for Tape & Reel packaging per EIA-296 standard, indicating JANTXV1N4134C-1/TR is supplied on carrier tape for automated pick-and-place assembly. Per the Mechanical and Packaging section (page 2), TR is a standard option for this series; it does not affect electrical specifications or qualification level.
