Product details
Overview
JANTXV1N4122C-1/TR from Microsemi is a 36 V, ±2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTXV level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTXV1N4122C-1/TR datasheet, JANTXV1N4122C-1/TR pinout, JANTXV1N4122C-1/TR application, or JANTXV1N4122C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), noise density (1 µV/√Hz), dynamic impedance (200 Ω), temperature coefficient (+0.095 %/°C), and JANTXV-level qualification for extended temperature operation.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 36 V at 250 mA test current, exhibiting low noise density (1 µV/√Hz) and stable regulation across –65 °C to +175 °C junction temperature range. Its metallurgical bond construction ensures mechanical robustness and hermetic sealing per MIL-PRF-19500/435.
The JANTXV1N4122C-1/TR delivers 36 V regulation with ±2% tolerance (denoted by "C" suffix), 200 Ω dynamic impedance at IZT, and a positive temperature coefficient of +0.095 %/°C - enabling predictable voltage drift in high-temperature environments without external compensation.
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 |
|---|---|---|---|
| 1N4122US-1/TR | Same 36 V ±2% Zener voltage but in surface-mount DO-213AA package; no JANTXV qualification | Lacks military screening and extended temperature validation; suitable only for commercial industrial designs | Select when board space constraints require SMT mounting and MIL-spec compliance is not required |
| JANS1N4122C-1 | Identical electrical specs and DO-35 package, but qualified to JANS (highest MIL-PRF-19500 level) with full lot traceability and radiation hardness data | Required for space-grade and nuclear-hardened systems where single-event burnout (SEB) immunity is mandated | Select when radiation tolerance, full lot acceptance testing, and 100% screening per MIL-STD-750 are mandatory |
Compared with JANTXV1N4122C-1/TR, the 1N4122US-1/TR offers footprint reduction at the cost of reliability assurance, while the JANS1N4122C-1 adds radiation hardness verification and full lot traceability - making it the only choice for spaceflight-critical voltage references.

FAQ
What is the Zener voltage tolerance of JANTXV1N4122C-1/TR?
The JANTXV1N4122C-1/TR has a Zener voltage tolerance of ±2%, indicated by the "C" suffix in its part number. This tolerance is specified at 25 °C with 250 mA test current and applies across the full qualified temperature range when used within its power derating limits.
Is JANTXV1N4122C-1/TR RoHS compliant?
No, JANTXV1N4122C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants; JANTXV-level devices retain tin-lead plating to meet MIL-STD-750 solderability and reliability requirements.
What does the "TR" suffix mean in JANTXV1N4122C-1/TR?
"TR" denotes tape-and-reel packaging per EIA-296 standard, enabling automated pick-and-place assembly. The base part JANTXV1N4122C-1 is identical electrically and mechanically; "TR" only indicates packaging format and does not affect qualification level or performance parameters of JANTXV1N4122C-1/TR.
How is the temperature coefficient of JANTXV1N4122C-1/TR applied in circuit design?
The JANTXV1N4122C-1/TR has a temperature coefficient of +0.095 %/°C, meaning its Zener voltage increases by approximately 34.2 mV per °C rise from 25 °C. Designers use this value to calculate worst-case regulation drift across –65 °C to +175 °C, ensuring system margins remain intact under thermal stress.
Can JANTXV1N4122C-1/TR replace commercial-grade 1N4122 diodes in existing designs?
JANTXV1N4122C-1/TR is physically and electrically compatible with commercial 1N4122 variants in DO-35 package, but introduces JANTXV-level screening, tighter process controls, and extended temperature validation. It may be substituted where enhanced reliability, traceability, or MIL-spec compliance is required - though requalification per application standards is recommended.
