Product details
Overview
JANTXV1N4116D-1/TR from Microsemi is a 24.0 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial-leaded package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4116D-1/TR datasheet, JANTXV1N4116D-1/TR pinout, JANTXV1N4116D-1/TR application, or JANTXV1N4116D-1/TR equivalent, this part delivers precise low-noise voltage reference with 150 Ω dynamic impedance at 250 mA test current, -65 °C to +175 °C operating range, and hermetically sealed construction for mission-critical analog biasing and overvoltage protection.
Technical Context
This Zener diode operates in reverse breakdown to maintain stable 24.0 V output across wide current (250 mA IZT, up to 40 mA IZM) and temperature (-65 °C to +175 °C) ranges. Its internal metallurgical bond ensures mechanical robustness under thermal cycling and shock.
It exhibits low noise density (1 µV/√Hz typical), minimal capacitance (≈1.5 pF at 24 V), and a positive temperature coefficient of +0.090 %/°C - enabling predictable drift compensation in precision reference circuits.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4116US-1 | Same 24 V, 1% spec but in DO-213AA surface-mount package; no axial leads. | Requires SMT reflow process; unsuitable for through-hole prototyping or high-vibration mechanical retention. | Select when board space is constrained and automated assembly is used. |
| JAN1N4116D-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (less stringent screening than JANTXV). | Lacks JANTXV-level burn-in and radiation assurance; not approved for Class H or space-qualified programs. | Select for cost-sensitive ground-based military systems where full JANTXV screening is unnecessary. |
Compared with JANTXV1N4116D-1/TR, the 1N4116US-1 offers identical regulation performance in a smaller footprint but sacrifices mechanical ruggedness and hand-solderability, while the JAN1N4116D-1 reduces procurement cost and lead time at the expense of mission-critical reliability validation.

FAQ
What is the Zener voltage tolerance of JANTXV1N4116D-1/TR?
JANTXV1N4116D-1/TR has a nominal Zener voltage of 24.0 V with ±1% tolerance, indicated by the "D" suffix in its part number per Microsemi's nomenclature. This tolerance is guaranteed at 250 mA test current and 25 °C ambient, and remains stable across its full -65 °C to +175 °C operating junction temperature range due to JANTXV-level screening.
Is JANTXV1N4116D-1/TR RoHS compliant?
No, JANTXV1N4116D-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts; JANTXV-level devices retain tin-lead plating to meet MIL-STD-750 solderability and reliability requirements for high-reliability applications.
What is the maximum Zener current IZM for JANTXV1N4116D-1/TR?
The maximum Zener current IZM for JANTXV1N4116D-1/TR is 40 mA, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2. This value corresponds to the current at which the device reaches its rated 500 mW power dissipation at 24.0 V, assuming ideal thermal conditions at 25 °C.
How does the temperature coefficient affect JANTXV1N4116D-1/TR in circuit design?
JANTXV1N4116D-1/TR has a temperature coefficient αVZ of +0.090 %/°C, meaning its Zener voltage increases by approximately 21.6 mV per °C rise in junction temperature. Designers must account for this drift in precision references - for example, a 50 °C rise yields ~1.08 V increase - using thermal management or compensation networks.
Can JANTXV1N4116D-1/TR be used as a replacement for commercial 1N4116 diodes?
JANTXV1N4116D-1/TR shares identical electrical specifications (24.0 V, 1%, DO-35) with commercial 1N4116 variants but adds JANTXV-level military qualification, including extended temperature screening, burn-in, and radiation hardness. It is physically pin-compatible but should only replace commercial parts in applications requiring MIL-PRF-19500/435 compliance and assured reliability.
