Product details
Overview
JANTXV1N4115D-1/TR from Microsemi is a 22 V, 1% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JANTXV level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power supplies and precision reference circuits.
For engineers reviewing the JANTXV1N4115D-1/TR datasheet, JANTXV1N4115D-1/TR pinout, JANTXV1N4115D-1/TR application, or JANTXV1N4115D-1/TR equivalent, this part delivers verified 22 V Zener regulation at 250 mA test current, <0.01 µA reverse leakage at 17.6 V, 150 Ω dynamic impedance, and +0.090 %/°C temperature coefficient - critical for stable biasing in radiation-hardened analog front-ends.
Technical Context
This device operates as a two-terminal voltage reference with cathode-banded polarity, requiring reverse-bias connection where the banded end is positive relative to the anode. Its metallurgical bond ensures low noise density (1 µV/√Hz typical at 22 V) and minimal capacitance (≈2.5 pF), enabling use in low-jitter timing references and precision ADC/DAC bias networks.
Thermal resistance junction-to-lead is 250 °C/W at 10 mm lead length, supporting reliable operation up to +175 °C junction temperature. Power derating begins linearly at +50 °C ambient, reaching zero dissipation at +175 °C - essential for thermal design in sealed avionics enclosures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 22.0 V ±1% at 250 mA - enables precise 22 V rail regulation with tight tolerance for reference-grade analog circuits. |
| Power Dissipation | 500 mW at +25 °C - supports continuous regulation in compact through-hole designs without forced cooling. |
| Zener Impedance ZZT | 150 Ω max at 250 mA - ensures stable output under varying load current, minimizing regulation error in feedback loops. |
| Reverse Leakage IR | ≤0.01 µA at 17.6 V - guarantees negligible current draw in high-impedance bias networks and low-power standby modes. |
| Temp. Coefficient αVZ | +0.090 %/°C - provides predictable, monotonic drift for temperature-compensated reference designs. |
| Noise Density ND | 1 µV/√Hz typical - critical for low-noise amplifiers, precision sensors, and RF bias applications requiring clean DC references. |
| Junction Temp. Range | -65 to +175 °C - validated for extended-range operation in space-grade and military environmental profiles. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4115US-1TR | Same 22 V, 1% spec but in surface-mount DO-213AA package; no axial leads; RoHS-compliant matte-tin plating. | Used where board space is constrained and reflow assembly required; lacks JANTXV qualification. | Select when commercial-grade reliability suffices and automated placement is mandatory. |
| JANS1N4115D-1 | Identical electrical specs and DO-35 package, but qualified to JANS level (highest MIL-PRF-19500 reliability tier) with full lot traceability and radiation testing. | Required for manned spaceflight and nuclear command systems where failure probability must be <1×10⁻⁹/hour. | Choose only when JANS-level documentation, screening, and radiation assurance are contractually mandated. |
Compared with JANTXV1N4115D-1/TR, the 1N4115US-1TR trades axial-mount flexibility and military qualification for SMT compatibility, while JANS1N4115D-1 adds extreme reliability overhead - making JANTXV1N4115D-1/TR the optimal balance of performance, qualification, and cost for most defense electronics programs.

FAQ
What is the Zener voltage tolerance of JANTXV1N4115D-1/TR?
JANTXV1N4115D-1/TR has a nominal Zener voltage of 22.0 V with a tolerance of ±1%, indicated by the "D" suffix in its part number per Microsemi's nomenclature standard. This tight tolerance is achieved through post-process binning and is verified at 250 mA test current under thermal equilibrium at +25 °C ambient, supporting high-accuracy reference applications without external trimming.
Is JANTXV1N4115D-1/TR RoHS compliant?
No, JANTXV1N4115D-1/TR is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4115D-1e3); JANTXV-level parts retain traditional tin-lead plating to meet MIL-STD-750 solderability requirements and avoid reliability risks associated with pure matte-tin finishes in high-reliability thermal cycling environments.
What is the maximum reverse leakage current for JANTXV1N4115D-1/TR?
JANTXV1N4115D-1/TR specifies a maximum reverse leakage current (IR) of 0.01 µA at 17.6 V (80% of nominal VZ). This ultra-low leakage is confirmed in Microsemi's T4-LDS-0245-2 datasheet and enables use in high-impedance bias networks where even femtoamp-level currents would cause unacceptable offset errors.
Does JANTXV1N4115D-1/TR require heatsinking in standard operation?
No, JANTXV1N4115D-1/TR does not require external heatsinking for operation at ≤500 mW within its specified thermal limits. With a junction-to-lead thermal resistance of 250 °C/W and rated power of 500 mW at +25 °C, it safely dissipates full power using standard 10 mm lead length on FR4 PCBs - provided ambient temperature remains below +50 °C before linear derating applies.
How is polarity marked on JANTXV1N4115D-1/TR?
JANTXV1N4115D-1/TR uses a single black band on the glass body to indicate the cathode terminal. The banded end must be connected to the higher-potential node (e.g., regulated output rail), while the unbanded end serves as the anode (ground or return path). This marking conforms to JEDEC DO-35 standards and is laser-verified during MIL-PRF-19500 screening.
