Product details
Overview
JANTXV1N4134D-1 from Microsemi is a 500 mW, 91 V, 1% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial 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 datasheet, JANTXV1N4134D-1 pinout, JANTXV1N4134D-1 application, or JANTXV1N4134D-1 equivalent, key selection criteria include its 91 V nominal Zener voltage at 250 mA test current, 1200 Ω dynamic impedance, 40 µA maximum reverse leakage at 73 V, ±0.1% temperature coefficient, and hermetically sealed DO-35 construction for stable operation across –65 °C to +175 °C.
Technical Context
This device operates as a precision shunt voltage regulator with a sharp breakdown knee at IZK = 250 mA, enabling stable reference generation under wide load and temperature variation. Its internal metallurgical bond ensures low noise density (1 µV/√Hz typical at low voltages) and radiation hardness per MicroNote 050.
The JANTXV1N4134D-1 exhibits a positive temperature coefficient of +0.100 %/°C above 50 V, supporting predictable thermal drift compensation in analog reference circuits. It is rated for 0.5 W average power dissipation with linear derating from 50 °C to zero at 175 °C on standard FR4 PCBs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANS1N4134D-1 | JANS-level qualification with additional burn-in and radiation testing beyond JANTXV | Required for Class S spaceflight hardware; higher cost and longer lead time | Select when full MIL-PRF-19500/435 JANS screening and 100 krad(Si) TID validation are mandated |

FAQ
What is the Zener voltage tolerance of JANTXV1N4134D-1?
The JANTXV1N4134D-1 has a nominal Zener voltage of 91.0 V with a ±1% tolerance, as indicated by the "D" suffix in the part number per Microsemi's nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, and applies across the full operating temperature range of –65 °C to +175 °C per MIL-PRF-19500/435 requirements.
Is JANTXV1N4134D-1 RoHS compliant?
No, the JANTXV1N4134D-1 is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are only available for commercial-grade variants; JANTXV-level parts retain tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability applications.
What is the maximum reverse leakage current for JANTXV1N4134D-1?
The JANTXV1N4134D-1 has a maximum reverse leakage current (IR) of 0.01 µA at VR = 73 V, as specified in the Electrical Characteristics table on page 3 of the T4-LDS-0245-2 datasheet. This ultra-low leakage supports high-impedance bias networks and precision reference applications.
How does the temperature coefficient of JANTXV1N4134D-1 affect its regulation accuracy?
The JANTXV1N4134D-1 has a temperature coefficient of +0.100 %/°C, meaning its Zener voltage increases by approximately 91 mV per °C rise. This predictable positive drift allows designers to compensate in multi-stage references or select complementary components to achieve net-zero TC over –55 °C to +125 °C.
Can JANTXV1N4134D-1 be used in surface-mount designs?
The JANTXV1N4134D-1 is packaged in DO-35 (axial-leaded), making it unsuitable for standard SMT assembly. For surface-mount equivalents, Microsemi offers the 1N4134UR-1 in DO-213AA package - identical electrical specs but different mechanical form factor and qualification level.
