Product details
Overview
JANTX1N4132D-1 from Microsemi is a 500 mW, 82 V, 1% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to MIL-PRF-19500/435 JANTX level for high-reliability voltage regulation in aerospace and defense power supplies.
For engineers reviewing the JANTX1N4132D-1 datasheet, JANTX1N4132D-1 pinout, JANTX1N4132D-1 application, or JANTX1N4132D-1 equivalent, key selection criteria include Zener voltage accuracy (±1%), low noise density (≤1 µV/√Hz), radiation hardness, hermetic glass packaging, and military-grade thermal derating behavior.
Technical Context
This device operates as a precision shunt voltage regulator with a nominal Zener voltage of 82.0 V at 250 mA test current, exhibiting a positive temperature coefficient of +0.100 %/°C and dynamic impedance of 800 Ω at IZT. Its metallurgical bond construction ensures stable breakdown characteristics under thermal cycling and radiation exposure.
Designed for operation in the reverse-biased breakdown region, it delivers regulated output with ≤0.01 µA reverse leakage at VR = 65.6 V and supports continuous dissipation up to 500 mW at TC = 25 °C, linearly derated to zero at 175 °C per MIL-PRF-19500/435 requirements.

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 electrical specs, 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 board space is constrained and automated placement is available |
| JAN1N4132D-1 | Identical electrical and mechanical specs, but qualified only to JAN level (not JANTX); lower screening rigor | Approved for commercial/military ground systems but not flight-critical subsystems per DoD standards | Select when full JANTX screening is not required to reduce cost and lead time |
Compared with JANTX1N4132D-1, the 1N4132US-1 offers identical regulation performance in a smaller footprint but eliminates manual assembly flexibility, while the JAN1N4132D-1 reduces procurement cost and cycle time at the expense of reduced burn-in and environmental test coverage required for airborne platforms.

FAQ
What is the Zener voltage tolerance for JANTX1N4132D-1?
JANTX1N4132D-1 has a nominal Zener voltage of 82.0 V with a tight ±1% tolerance, denoted by the "D" suffix in the part number per MIL-PRF-19500/435 nomenclature. This tolerance is verified at 250 mA test current and 25 °C ambient, ensuring predictable regulation in precision feedback networks where post-manufacturing trimming is impractical.
Is JANTX1N4132D-1 suitable for high-temperature operation?
Yes, JANTX1N4132D-1 is rated for junction temperatures from –65 °C to +175 °C and features linear power derating from 500 mW at 25 °C to zero at 175 °C. Its metallurgically bonded glass construction maintains parameter stability under thermal cycling, making it suitable for engine bay electronics and downhole oilfield tools where sustained 150 °C ambient is common.
Does JANTX1N4132D-1 meet RoHS requirements?
No, JANTX1N4132D-1 is not RoHS compliant. Per the manufacturer's documentation, RoHS-compliant versions (e.g., with "e3" suffix) are available only for commercial-grade variants (blank reliability level), not for JANTX-qualified parts. The JANTX1N4132D-1 uses traditional tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and long-term reliability in legacy military assemblies.
What is the maximum reverse leakage current for JANTX1N4132D-1?
The maximum reverse leakage current (IR) for JANTX1N4132D-1 is 0.01 µA measured at VR = 65.6 V (80% of nominal VZ). This ultra-low leakage supports use in battery-powered instrumentation and energy-harvesting circuits where standby current must remain below 100 nA to extend operational life.
How does the noise performance of JANTX1N4132D-1 compare to lower-voltage Zeners?
JANTX1N4132D-1 exhibits ≤1 µV/√Hz noise density at 250 mA, consistent with the trend that higher-voltage Zeners in this family show lower noise than sub-6.8 V devices. This makes JANTX1N4132D-1 preferable over lower-voltage alternatives in high-fidelity reference applications where broadband noise directly impacts measurement resolution.
