For engineers reviewing the JANTX1N4132C-1/TR datasheet, JANTX1N4132C-1/TR pinout, JANTX1N4132C-1/TR application, or JANTX1N4132C-1/TR equivalent, this page delivers verified Zener voltage, temperature coefficient, dynamic impedance, noise density, and military qualification details critical for precision reference and overvoltage protection design.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 82 V at 250 mA test current, exhibiting +0.100 %/°C temperature coefficient and 800 Ω dynamic impedance at IZT. Its metallurgical bond construction ensures stable regulation across -65 °C to +175 °C junction temperature range.
Designed for high-reliability mil-spec applications, JANTX1N4132C-1/TR maintains ≤0.01 µA reverse leakage at 65.6 V (80% of VZ), delivers 1 µV/√Hz noise density at low voltages, and supports 40 mA maximum Zener current under derated thermal conditions per MIL-PRF-19500/435.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4132US-1 | Same 82 V ±2% Zener, but in surface-mount DO-213AA package; no axial leads | Requires PCB rework for SMT assembly; unsuitable for through-hole prototyping or wire-wrap | Select when automated placement and board space savings outweigh lead-forming flexibility |
| JAN1N4132C-1 | Identical electrical specs and DO-35 package, but qualified only to JAN level (lower screening than JANTX) | Lacks JANTX-level lot acceptance testing and extended environmental stress screening | Select only for non-critical subsystems where full JANTX reliability assurance is not mandated |
Compared with JANTX1N4132C-1/TR, 1N4132US-1 trades axial-leaded serviceability for SMT manufacturability, while JAN1N4132C-1 reduces cost and lead time at the expense of JANTX-level burn-in and thermal shock validation required for flight-critical avionics.

FAQ
What is the Zener voltage tolerance of JANTX1N4132C-1/TR?
JANTX1N4132C-1/TR has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its part number. This tighter tolerance enables higher accuracy in voltage reference and overvoltage protection circuits compared to standard ±5% variants like JANTX1N4132-1/TR, reducing calibration effort in precision applications.
Is JANTX1N4132C-1/TR RoHS compliant?
No, JANTX1N4132C-1/TR is not RoHS compliant. Per Microsemi documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade parts, not for JANTX-level qualified devices. The JANTX1N4132C-1/TR uses tin-lead plating per MIL-STD-750 and retains legacy Pb content for solderability and reliability in high-reliability assemblies.
What is the maximum Zener current IZM for JANTX1N4132C-1/TR?
The maximum Zener current IZM for JANTX1N4132C-1/TR is 40 mA, as specified in the Electrical Characteristics table. This value assumes operation within the 500 mW power limit and proper thermal management; exceeding 40 mA risks exceeding PM(AV) when combined with VZ × IZ losses, especially above 50 °C ambient.
How does the temperature coefficient affect JANTX1N4132C-1/TR performance?
JANTX1N4132C-1/TR has a temperature coefficient αVZ of +0.100 %/°C, meaning its Zener voltage increases by approximately 82 mV per °C rise in junction temperature. This predictable positive drift must be accounted for in wide-temperature-range designs, such as avionics systems operating from -55 °C to +125 °C, where total VZ shift can exceed ±8 V.
What packaging option does JANTX1N4132C-1/TR use?
JANTX1N4132C-1/TR uses the hermetically sealed axial-leaded DO-35 (DO-204AH) glass package, with cathode identified by a band. The "TR" suffix indicates tape-and-reel packaging per EIA-296, enabling automated insertion; lead length is specified at 1.0–1.5 inches (25.4–38.1 mm) for thermal resistance compliance.
