Product details
Overview
JANTX1N4115D-1/TR from Microsemi is a 22 V, 1% tolerance, 500 mW axial-leaded Zener diode in DO-35 (DO-204AH) glass package, qualified to JANTX level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power conditioning and precision reference circuits.
For engineers reviewing the JANTX1N4115D-1/TR datasheet, JANTX1N4115D-1/TR pinout, JANTX1N4115D-1/TR application, or JANTX1N4115D-1/TR equivalent, key selection criteria include Zener voltage tolerance (±1%), dynamic impedance (150 Ω @ 250 mA), noise density (1 µV/√Hz), temperature coefficient (+0.090 %/°C), and military-grade thermal derating behavior.
Technical Context
This device operates as a reverse-biased voltage reference with metallurgically bonded junction construction, enabling stable regulation across –65 °C to +175 °C junction temperature range and low noise performance critical for analog signal chains. Its 1% voltage tolerance and +0.090 %/°C tempco support precision biasing in instrumentation amplifiers and ADC reference buffers.
The DO-35 package provides hermetic glass sealing and axial-leaded mechanical robustness suitable for high-vibration environments. Thermal resistance of 250 °C/W (junction-to-lead, 10 mm lead length) enables reliable operation at up to 500 mW dissipation when properly heatsunk.
Key Specifications

| Zener Voltage VZ | 22.0 V ±1% @ 250 mA - ensures tight output regulation in feedback loops requiring <±0.22 V deviation. |
| Power Dissipation | 500 mW @ TL = 25 °C - supports continuous operation in compact power supplies with linear derating to zero at 175 °C. |
| Zener Impedance ZZT | 150 Ω @ 250 mA - maintains low AC impedance for ripple rejection in low-noise reference designs. |
| Noise Density | 1 µV/√Hz @ 250 mA - minimizes broadband noise contribution in precision analog front-ends and sensor excitation circuits. |
| Tempco αVZ | +0.090 %/°C - enables predictable drift compensation in wide-temperature-range industrial control systems. |
| Reverse Leakage IR | 10 nA @ 17.6 V - guarantees minimal current draw in high-impedance bias networks and battery-powered standby circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4115US-1 | Same 22 V, 1% spec but in DO-213AA surface-mount package; no axial leads. | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical mounting. | Select only when board space constraints mandate SMT and thermal management allows 250 °C/W junction-to-ambient. |
| JAN1N4115D-1 | Identical electrical specs and DO-35 package but qualified only to JAN level (lower screening than JANTX). | Not approved for mission-critical flight hardware; acceptable for ground-test equipment and non-flight avionics. | Choose when cost sensitivity outweighs full JANTX environmental testing requirements. |
Compared with JANTX1N4115D-1/TR, the 1N4115US-1 offers footprint reduction at the expense of mechanical ruggedness, while JAN1N4115D-1 trades screening rigor for lower procurement cost-neither is pin-compatible in the sense of identical qualification scope or mounting form factor.

FAQ
What is the Zener voltage tolerance of JANTX1N4115D-1/TR?
JANTX1N4115D-1/TR has a nominal Zener voltage of 22.0 V with ±1% tolerance, meaning its actual regulation voltage falls between 21.78 V and 22.22 V when tested at 250 mA and 25 °C. This tight tolerance is achieved through post-trimming and verified during JANTX-level screening per MIL-PRF-19500/435.
Does JANTX1N4115D-1/TR require external heat sinking?
JANTX1N4115D-1/TR can dissipate up to 500 mW at 25 °C lead temperature without external heat sinking, but its thermal resistance is 250 °C/W junction-to-lead. For sustained operation above 250 mW or ambient temperatures exceeding 50 °C, a minimum 3/8-inch (10 mm) lead length from the body is required to meet derating curves-no additional heatsink is needed if this condition is met.
Is JANTX1N4115D-1/TR RoHS compliant?
No, JANTX1N4115D-1/TR is not RoHS compliant. The "e3" suffix denotes RoHS-compliant versions, which are only available for commercial-grade parts (e.g., 1N4115D-1e3). JANTX-level parts retain tin-lead plating per MIL-STD-750 to ensure solderability and reliability under military thermal cycling profiles.
What is the maximum reverse leakage current for JANTX1N4115D-1/TR?
JANTX1N4115D-1/TR exhibits a maximum reverse leakage current (IR) of 10 nA at 17.6 V (80% of VZ). This ultra-low leakage supports high-impedance bias networks in battery-powered instrumentation and ensures negligible current draw in standby modes of avionics subsystems.
How does the temperature coefficient affect JANTX1N4115D-1/TR performance?
JANTX1N4115D-1/TR has a temperature coefficient of +0.090 %/°C, meaning its Zener voltage increases by approximately 19.8 mV per degree Celsius rise above 25 °C. This predictable positive drift allows designers to compensate for thermal effects in closed-loop regulators and reference buffers using simple resistor networks.
