For engineers reviewing the JANTXV1N4120C-1/TR datasheet, JANTXV1N4120C-1/TR pinout, JANTXV1N4120C-1/TR application, or JANTXV1N4120C-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 military-grade reliability qualification.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 30.0 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 under thermal cycling and vibration stress.
The JANTXV1N4120C-1/TR features a cathode band polarity indicator and is rated for 0.5 W average power dissipation with linear derating above 50 °C lead temperature. It delivers 22.8 mA maximum Zener current at rated power and maintains <0.01 µA reverse leakage at 24 V.
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 |
|---|---|---|---|
| 1N4120US-1/TR | Same 30 V, ±2%, DO-213AA surface-mount package; 250 mW rating; no JANTXV qualification. | Limited to commercial-grade PCB assembly; unsuitable for through-hole mounting or high-reliability screening. | Select only for cost-sensitive, non-military surface-mount designs where 250 mW suffices. |
| JANS1N4120C-1/TR | Identical electrical specs and DO-35 package; qualified to JANS (highest MIL-PRF-19500 level) with extended screening. | Required for spaceflight and nuclear-hardened systems; adds burn-in, radiation testing, and lot traceability. | Choose when mission-critical reliability exceeds JANTXV requirements, e.g., satellite payload electronics. |
Compared with JANTXV1N4120C-1/TR, the 1N4120US-1/TR reduces board space but sacrifices power handling and qualification; the JANS1N4120C-1/TR retains identical performance while adding radiation tolerance and extended environmental screening for ultimate mission assurance.

Is JANTXV1N4120C-1/TR suitable for high-temperature operation?
Yes, JANTXV1N4120C-1/TR is rated for junction temperatures from –65 °C to +175 °C and qualified per MIL-PRF-19500/435. Its glass DO-35 package and metallurgical bond construction enable reliable operation in engine bay electronics and satellite thermal control subsystems where ambient temperatures exceed 125 °C.
Does JANTXV1N4120C-1/TR have low-noise characteristics?
Yes, JANTXV1N4120C-1/TR exhibits a noise density of 1 µV/√Hz at 30 V, verified per Microsemi's T4-LDS-0245-2 specification. This ultra-low noise performance makes JANTXV1N4120C-1/TR ideal for precision analog references in instrumentation amplifiers and high-resolution ADC circuits where reference noise directly limits system accuracy.
What does the "TR" suffix mean in JANTXV1N4120C-1/TR?
The "TR" suffix in JANTXV1N4120C-1/TR indicates tape-and-reel packaging per EIA-296 standard, enabling automated SMT placement despite its axial-leaded DO-35 form factor. This configuration supports high-volume manufacturing while preserving the military-grade reliability and electrical performance of the base JANTXV1N4120C-1 part.
How does JANTXV1N4120C-1/TR differ from commercial-grade 1N4120 diodes?
JANTXV1N4120C-1/TR differs from commercial 1N4120 variants by its JANTXV-level qualification per MIL-PRF-19500/435, including extended temperature testing, hermeticity validation, and lot traceability. It also features tighter 2% voltage tolerance and guaranteed 1 µV/√Hz noise density-specifications not assured in non-military versions of JANTXV1N4120C-1/TR.
