Product details
Overview
JANTXV1N4134D-1/TR from Microsemi is a 500 mW, 91 V, 1% 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 JANTXV1N4134D-1/TR datasheet, JANTXV1N4134D-1/TR pinout, JANTXV1N4134D-1/TR application, or JANTXV1N4134D-1/TR equivalent, key selection criteria include Zener voltage (91 V), tolerance (±1%), dynamic impedance (1200 Ω at 250 mA), noise density (1 µV/√Hz), and JANTXV-level qualification for extended temperature (-65 °C to +175 °C) operation.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 91 V at 250 mA test current, exhibiting low noise density (1 µV/√Hz) and stable regulation across wide current (up to 69.2 mA max Zener current) and temperature ranges (-65 °C to +175 °C junction).
Its metallurgical bond construction ensures mechanical robustness and radiation hardness per Microsemi MicroNote 050, while the DO-35 glass package provides hermetic sealing and ESD insensitivity per MIL-STD-750 method 1020.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4134US-1TR | Same 91 V, 1% spec, but in surface-mount DO-213AA package; no axial leads | Requires PCB redesign for SMT assembly; eliminates lead-induced inductance in RF-sensitive clamps | Select when automated assembly, space constraints, or RF performance outweigh axial-mount heritage requirements |
| JANS1N4134D-1 | Identical electrical specs and DO-35 package, but qualified to JANS (highest MIL-PRF-19500/435 level) | Required for mission-critical systems where full JANS screening (radiation, burn-in, lot acceptance) is mandated | Select only when JANS-level documentation, traceability, and screening compliance are contractually required |
Compared with JANTXV1N4134D-1/TR, the 1N4134US-1TR offers SMT compatibility at the cost of board layout change, while JANS1N4134D-1 delivers enhanced screening rigor without electrical or mechanical deviation-enabling direct substitution where qualification level permits.

FAQ
What is the Zener voltage and tolerance of JANTXV1N4134D-1/TR?
JANTXV1N4134D-1/TR has a nominal Zener voltage of 91 V at 250 mA test current with a tight ±1% tolerance, confirmed in the Electrical Characteristics table on page 3 of Microsemi T4-LDS-0245-2. This tolerance is achieved via post-process binning and applies across the full qualified temperature range.
What does the "D" suffix mean in JANTXV1N4134D-1/TR?
The "D" suffix in JANTXV1N4134D-1/TR denotes ±1% Zener voltage tolerance per the Part Nomenclature section on page 2 of Microsemi T4-LDS-0245-2. It is distinct from "C" (±2%) and blank (±5%), and is laser-trimmed during manufacturing to meet this specification.
Is JANTXV1N4134D-1/TR RoHS compliant?
No, JANTXV1N4134D-1/TR is not RoHS compliant. Per the datasheet, RoHS-compliant versions (suffix "e3") are available only for commercial-grade parts; JANTXV-level devices like JANTXV1N4134D-1/TR use tin-lead plating and are exempt from RoHS per MIL-PRF-19500/435 requirements.
What is the maximum Zener current IZM for JANTXV1N4134D-1/TR?
The maximum Zener current IZM for JANTXV1N4134D-1/TR is 69.2 mA, as specified in the Electrical Characteristics table on page 3 of Microsemi T4-LDS-0245-2. This value corresponds to the current at which the device dissipates its rated 500 mW at 91 V, assuming thermal equilibrium at 25 °C lead temperature.
How is polarity marked on JANTXV1N4134D-1/TR?
JANTXV1N4134D-1/TR uses a cathode band marking on the glass DO-35 body, as stated in the Mechanical and Packaging section on page 2. The banded end is the cathode and must be held at a higher potential than the anode for proper Zener regulation operation.
