Product details
Overview
JANTXV1N4115D-1 from Microsemi is a 500 mW, 22 V, 1% tolerance metallurgically bonded glass Zener diode in DO-35 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 datasheet, JANTXV1N4115D-1 pinout, JANTXV1N4115D-1 application, or JANTXV1N4115D-1 equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (1 µV/√Hz), radiation hardness, and military-grade thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 22 V at 250 mA test current, dynamic impedance of 150 Ω at IZT, and temperature coefficient of +0.090 %/°C - enabling stable regulation across wide temperature ranges in analog signal conditioning and power rail supervision.
Its hermetically sealed DO-35 glass package provides ESD immunity per MIL-STD-750 Method 1020, minimal capacitance (~17 pF), and inherent radiation hardness validated per Microsemi MicroNote 050 - critical for space-qualified and defense electronics where long-term parametric stability under ionizing radiation is required.

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% Zener voltage but in surface-mount DO-213AA package; no JANTXV qualification. | Limited to commercial-grade PCB assembly; unsuitable for hermetic or high-vibration environments. | Select only for cost-sensitive, non-military surface-mount designs where MIL screening is unnecessary. |
| JANTXV1N4114D-1 | 20 V nominal Zener voltage (±1%), identical package, qualification, and noise performance. | Used where 20 V reference is specified in legacy schematics or tighter low-voltage margin is required. | Choose when system-level tolerance analysis favors 20 V over 22 V for improved headroom or compatibility with existing designs. |
Compared with JANTXV1N4115D-1, the 1N4115US-1 sacrifices military reliability for SMT manufacturability, while JANTXV1N4114D-1 offers a 2 V lower reference point with identical robustness - enabling design flexibility within the same qualified family.
