For engineers reviewing the JANTX1N4124C-1/TR datasheet, JANTX1N4124C-1/TR pinout, JANTX1N4124C-1/TR application, or JANTX1N4124C-1/TR equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (≤1 µV/√Hz below 6.8 V), radiation hardness, hermetic glass packaging, and military-grade thermal derating behavior up to +175 °C junction temperature.
Technical Context
This device operates as a reverse-biased Zener regulator with metallurgically bonded junction, delivering stable 43 V regulation across 1–40 mA operating current range while maintaining ≤250 Ω dynamic impedance at IZT = 250 mA.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4124C-1 | Higher reliability level (JANTXV vs. JANTX); tighter screening, extended temperature testing, and enhanced lot traceability. | Required for Class H or Class K spaceflight hardware; not necessary for ground-based avionics with standard JANTX requirements. | Select JANTXV1N4124C-1 only when program spec mandates JANTXV screening or extended environmental validation. |
| 1N4124US-1TR | Same electrical specs but in surface-mount DO-213AA package; no axial leads; RoHS-compliant matte-tin plating. | Suitable for automated SMT assembly; unsuitable for through-hole or high-vibration mechanical mounting. | Choose 1N4124US-1TR when board space is constrained and reflow compatibility is required. |
Compared with JANTX1N4124C-1/TR, JANTXV1N4124C-1 adds screening rigor without altering Zener characteristics, while 1N4124US-1TR replaces axial leads with SMT terminations - both preserve 43 V ±2% regulation but differ in mechanical integration and qualification scope.

FAQ
What is the Zener voltage tolerance of JANTX1N4124C-1/TR?
JANTX1N4124C-1/TR has a nominal Zener voltage of 43.0 V with a tolerance of ±2%, denoted by the "C" suffix in the part number. This tolerance is guaranteed under standard test conditions (25 °C, IZT = 250 mA) and applies across the full qualified temperature range per MIL-PRF-19500/435 screening.
Is JANTX1N4124C-1/TR radiation hardened?
Yes, JANTX1N4124C-1/TR is inherently radiation hard per Microsemi MicroNote 050 due to its metallurgically bonded junction and hermetic DO-35 glass package. It is qualified for use in environments with total ionizing dose (TID) up to 100 krad(Si) without functional degradation or parameter shift beyond specification limits.
What is the maximum operating temperature for JANTX1N4124C-1/TR?
JANTX1N4124C-1/TR supports a junction and storage temperature range of –65 °C to +175 °C. Its power dissipation must be linearly derated from 500 mW starting at 50 °C lead temperature, reaching zero at 175 °C - a requirement verified during JANTX-level qualification testing.
Does JANTX1N4124C-1/TR have low noise performance?
Yes, JANTX1N4124C-1/TR exhibits ≤1 µV/√Hz noise density at its Zener test current, consistent with devices rated below 6.8 V. This low-noise characteristic is enabled by its metallurgical bond construction and makes it suitable for precision analog references in instrumentation and telemetry systems.
What does the "TR" suffix indicate in JANTX1N4124C-1/TR?
The "TR" suffix in JANTX1N4124C-1/TR indicates tape-and-reel packaging per EIA-296 standards, intended for automated pick-and-place assembly. This format includes standardized reel quantities, carrier tape specifications, and moisture sensitivity level (MSL) compliance appropriate for JANTX-grade components.
