Product details
Overview
JAN1N4132D-1/TR from Microsemi is a 500 mW, 82 V, 1% tolerance metallurgically bonded glass Zener diode in DO-35 package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace and defense power supplies, reference circuits, and overvoltage protection.
For engineers reviewing the JAN1N4132D-1/TR datasheet, JAN1N4132D-1/TR pinout, JAN1N4132D-1/TR application, or JAN1N4132D-1/TR equivalent, key selection criteria include Zener voltage (82 V), tolerance (±1%), dynamic impedance (800 Ω at 250 mA), noise density (1 µV/√Hz), and MIL-qualified reliability level.
Technical Context
This axial-leaded Zener diode operates in reverse breakdown with cathode-banded polarity, delivering stable 82 V regulation across wide current (250 mA test point) and temperature (-65 °C to +175 °C) ranges. Its metallurgical bond ensures low thermal resistance (RθJL = 250 °C/W) and radiation hardness per MicroNote 050.
Designed for precision reference and clamping, it exhibits minimal capacitance (typ. <1.5 pF at 82 V), low noise (1 µV/√Hz), and tight temperature coefficient (+0.100 %/°C), enabling use in low-drift analog subsystems where stability under thermal stress is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 82 V ±1% at 250 mA - enables precise voltage clamping in 80–84 V rail protection and reference designs. |
| Power Dissipation | 500 mW at 25 °C, derated linearly to zero at 175 °C - supports continuous operation in high-temp military enclosures. |
| Dynamic Impedance ZZT | 800 Ω at IZT = 250 mA - ensures minimal output voltage shift under load transients in regulated supplies. |
| Noise Density | 1 µV/√Hz - critical for low-noise voltage references in precision instrumentation and ADC biasing. |
| Temp Coefficient αVZ | +0.100 %/°C - provides predictable, monotonic drift behavior for temperature-compensated circuits. |
| Reverse Leakage IR | 10 nA max at 65.6 V - guarantees negligible current draw in standby-mode protection circuits. |
| Junction Temp Range | -65 °C to +175 °C - validated for operation in extreme environments including space-grade thermal cycling. |
Pinout & Package
DO-35 (DO-204AH) hermetically sealed axial-glass package with tin-lead plating; cathode indicated by single black band; weight ≈ 0.2 g; lead length 25.4–38.1 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Forward conduction terminal | Connected to lower-potential node during Zener operation; must be negative relative to cathode for regulation. |
| Cathode (banded end) | Zener breakdown terminal | Connected to higher-potential node; voltage regulation occurs between cathode and anode when reverse biased. |
Key Features
| Feature | Design Value |
|---|---|
| MIL-PRF-19500/435 JAN qualification | Validated reliability for flight-critical systems with full traceability and screening per military standards. |
| Metallurgical bond construction | Eliminates interfacial delamination risk under thermal shock and vibration, ensuring long-term parameter stability. |
| 1% Zener voltage tolerance | Reduces need for post-assembly trimming in precision reference designs, lowering calibration cost and time. |
| Low noise density (1 µV/√Hz) | Enables direct use in high-resolution analog front-ends without external filtering or buffering stages. |
| Radiation hardness | Inherent TID tolerance per MicroNote 050 supports operation in low-earth orbit and nuclear-hardened platforms. |
Applications

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, 1% spec, but in DO-213AA surface-mount package; no axial leads. | Requires PCB re-layout for SMT assembly; unsuitable for through-hole prototyping or high-vibration mechanical mounting. | Select when automated SMT production and board space constraints outweigh need for axial-leaded serviceability. |
| JANTXV1N4132D-1 | Identical electrical specs and DO-35 package, but qualified to JANTXV level (enhanced screening, tighter parametric limits). | Required for Class H/V space programs where burn-in, life test, and lot acceptance testing exceed JAN requirements. | Select when mission-critical reliability validation beyond JAN-e.g., extended temperature cycling or radiation lot acceptance-is mandated. |
Compared with JAN1N4132D-1/TR, 1N4132US-1 trades axial-mount flexibility for SMT compatibility, while JANTXV1N4132D-1 adds screening rigor without altering regulation performance-enabling tiered qualification matching program risk profiles.

FAQ
What is the Zener voltage tolerance of JAN1N4132D-1/TR?
JAN1N4132D-1/TR has a Zener voltage tolerance of ±1%, denoted by the "D" suffix in its part number per Microsemi's nomenclature. This 82 V specification is guaranteed at 250 mA test current and 25 °C ambient, with full MIL-PRF-19500/435 JAN-level screening validating consistency across production lots.
Is JAN1N4132D-1/TR RoHS compliant?
No, JAN1N4132D-1/TR is not RoHS compliant. The "e3" RoHS suffix is only available on commercial-grade versions (e.g., 1N4132D-1e3); JAN-level parts retain tin-lead plating per MIL-STD-750 method 2026 to ensure solderability and reliability under military thermal cycling requirements.
What is the maximum reverse leakage current for JAN1N4132D-1/TR?
JAN1N4132D-1/TR specifies a maximum reverse leakage current (IR) of 10 nA at 65.6 V (80% of nominal VZ). This ultra-low leakage ensures minimal power loss in high-impedance reference divider networks and preserves accuracy in battery-backed monitoring circuits.
Can JAN1N4132D-1/TR be used in surface-mount designs?
No, JAN1N4132D-1/TR uses the axial-leaded DO-35 package and is not suitable for surface-mount assembly. For SMT equivalents, consider the 1N4132US-1 in DO-213AA package-same 82 V/1% spec but with solder pads instead of leads.
What is the thermal resistance junction-to-lead for JAN1N4132D-1/TR?
JAN1N4132D-1/TR has a thermal resistance junction-to-lead (RθJL) of 250 °C/W when measured with 10 mm (3/8″) lead length from body. This value enables accurate thermal modeling for derating calculations in chassis-mounted or heatsinked configurations per Figure 2 of the datasheet.
