Product details
Overview
JANTXV1N4961DUS/TR from Microsemi is a military-grade, hermetically sealed surface-mount Zener diode rated for 5 W power dissipation, with a nominal Zener voltage of 13 V at 100 mA test current, ±5% tolerance, and maximum dynamic impedance of 3.0 Ω at IZT. It operates across –65 °C to +175 °C and is used in high-reliability voltage regulation and overvoltage protection circuits in aerospace power supplies.
For engineers reviewing the JANTXV1N4961DUS/TR datasheet, JANTXV1N4961DUS/TR pinout, JANTXV1N4961DUS/TR application, or JANTXV1N4961DUS/TR equivalent, this part delivers verified 13 V regulation under 5 W thermal load, MIL-PRF-19500/356 qualification, voidless-glass hermetic sealing, and radiation-hardened construction for mission-critical analog biasing and reference stabilization.
Technical Context
This device functions as a precision shunt voltage regulator in feedback loops and reference networks, leveraging its low dynamic impedance (3.0 Ω) and tight voltage regulation (ΔVZ ≤ 0.9 V between 10%–50% IZM) to maintain stable bias points across wide temperature and current ranges. Its Category I metallurgical bond and triple-layer passivation ensure long-term reliability under thermal cycling and humidity stress.
The JANTXV1N4961DUS/TR uses a tungsten-slug glass package with copper end caps and Sn/Pb finish, enabling direct solder attachment without adhesive assist. Its cathode band marking and EIA-481-B tape-and-reel packaging support automated SMT assembly in Class H and Class K production environments.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4961US | No /TR suffix; bulk packaging instead of tape-and-reel; identical electrical specs and qualification level | Preferred for prototyping or low-volume hand-soldered builds where reel handling is unnecessary | Select JANTXV1N4961US when automated pick-and-place is not required and cost-per-unit is prioritized |
| 1N4961US | Commercial-grade (non-military); lacks MIL-PRF-19500/356 screening, radiation hardness, and extended temperature validation | Suitable only for benign-environment industrial controls, not aerospace or defense systems | Choose 1N4961US only for non-critical commercial designs where cost and availability outweigh reliability requirements |
Compared with JANTXV1N4961US and 1N4961US, the JANTXV1N4961DUS/TR provides guaranteed tape-and-reel delivery for SMT lines, full JANTXV screening including burn-in and temperature cycling, and documented radiation tolerance-making it the sole option for DO-160G Section 22 and MIL-STD-810H-compliant platforms.

FAQ
What is the Zener voltage tolerance for JANTXV1N4961DUS/TR?
The JANTXV1N4961DUS/TR has a nominal Zener voltage of 13 V with a tolerance of ±5%, as specified in the Microsemi SD44A datasheet. This tolerance applies at the test current IZT = 100 mA and ambient temperature of 25 °C. The part does not include tighter-tolerance suffixes (e.g., 'C' or 'D') - those apply only to commercial variants like 1N4961CUS or 1N4961DUS.
Is JANTXV1N4961DUS/TR compatible with lead-free reflow processes?
The JANTXV1N4961DUS/TR features Sn/Pb (tin/lead) terminations per the datasheet, and is not qualified for Pb-free reflow. Its end caps are explicitly specified as copper with Sn/Pb finish. For RoHS-compliant assembly, Microsemi recommends evaluating the newer Microchip M1N4961US family or consulting Microchip's obsolescence notice for Pb-free alternatives.
What is the maximum continuous Zener current IZM for JANTXV1N4961DUS/TR?
The maximum continuous Zener current IZM for JANTXV1N4961DUS/TR is 365 mA, calculated from its 5 W power rating and 13 V nominal Zener voltage (IZM = PD/VZ). This value is confirmed in the "ELECTRICAL CHARACTERISTICS" table on page 2 of SD44A, where IZM = 365 mA is listed for 1N4961US (identical to JANTXV1N4961DUS/TR electrically).
Does JANTXV1N4961DUS/TR have radiation hardness certification?
Yes - JANTXV1N4961DUS/TR is inherently radiation hard per Microsemi MicroNote 050, with documented tolerance to 100 krad(Si) total ionizing dose. This qualification stems from its voidless-glass hermetic construction and Category I metallurgical bond, and is validated for use in low-earth-orbit (LEO) satellite power systems.
What package outline does JANTXV1N4961DUS/TR use?
JANTXV1N4961DUS/TR uses the "E" package (also referenced as D-5B in Microsemi documentation), a surface-mount hermetic glass case with tungsten slugs and copper end caps. Dimensions and pad layout are provided on page 4 of SD44A, including optional center adhesive spot for enhanced mechanical retention.
