Product details
Overview
JAN1N4132C-1 from Microsemi is a 500 mW, 82 V, ±2% tolerance metallurgically bonded glass Zener diode in DO-35 (DO-204AH) axial package, qualified to JAN level per MIL-PRF-19500/435 for high-reliability voltage regulation in aerospace power conditioning and precision reference circuits.
For engineers reviewing the JAN1N4132C-1 datasheet, JAN1N4132C-1 pinout, JAN1N4132C-1 application, or JAN1N4132C-1 equivalent, key selection criteria include Zener voltage accuracy (±2%), low noise density (1 µV/√Hz), JANS-qualified thermal stability (–65°C to +175°C), and hermetic DO-35 packaging for radiation-hardened environments.
Technical Context
This device operates as a reverse-biased voltage reference with a nominal Zener voltage of 82 V at 250 mA test current, dynamic impedance of 800 Ω at IZT, and temperature coefficient of +0.100 %/°C - enabling stable regulation across wide temperature excursions in military-grade analog subsystems.
Its metallurgical bond construction ensures low leakage (IR ≤ 0.01 µA at VR = 65.6 V), minimal capacitance (~1.5 pF), and immunity to ESD per MIL-STD-750 Method 1020, supporting use in low-noise, high-stability reference designs where long-term parametric drift must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Zener Voltage VZ | 82 V ±2% at 250 mA - provides precise, repeatable reference under regulated load conditions. |
| Power Dissipation | 500 mW at 25°C, derated linearly to zero at 175°C - supports operation in high-ambient industrial/military enclosures. |
| Zener Impedance ZZT | 800 Ω at 250 mA - ensures minimal output voltage variation under dynamic load transients. |
| Noise Density ND | 1 µV/√Hz - enables use in ultra-low-noise analog references and precision instrumentation front-ends. |
| Reverse Leakage IR | ≤0.01 µA at 65.6 V - guarantees negligible current draw in standby or high-impedance bias networks. |
| Temp Coefficient αVZ | +0.100 %/°C - allows predictable voltage drift compensation in temperature-critical calibration circuits. |
| Junction Temp Range | –65°C to +175°C - meets extended environmental requirements for space-grade and avionics applications. |
Pinout & Package
DO-35 (DO-204AH) axial-leaded glass package with cathode indicated by band; operated with banded end positive for Zener regulation. Hermetically sealed, tin-lead plated leads solderable per MIL-STD-750 Method 2026.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Reference ground node | Connected to system common; establishes return path for Zener current and defines regulation reference point. |
| Cathode | Regulated output node | Banded end supplies stabilized 82 V output; must be biased positive relative to anode to maintain breakdown conduction. |

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 voltage but in surface-mount DO-213AA package; no axial leads. | Requires PCB re-layout for SMT assembly; unsuitable for through-hole prototyping or wire-wrap boards. | Select when automated assembly, board space constraints, or vibration resistance are prioritized over manual repairability. |
| JANTXV1N4132C-1 | Identical electrical specs but qualified to JANTXV level with enhanced screening (burn-in, thermal shock, hermeticity). | Required for Class H (high-reliability) avionics programs where failure rate must meet 0.1% per 1000 hrs. | Select when full JANTXV screening documentation and lot traceability are mandated by program spec. |
Compared with JAN1N4132C-1, the 1N4132US-1 offers identical regulation performance in a compact SMT form factor but sacrifices mechanical robustness and hand-soldering compatibility, while JANTXV1N4132C-1 adds rigorous reliability screening at higher cost and longer lead time for mission-critical deployments.

FAQ
What is the Zener voltage tolerance of JAN1N4132C-1?
JAN1N4132C-1 has a Zener voltage tolerance of ±2%, denoted by the "C" suffix in its nomenclature. This means its nominal 82 V Zener voltage is guaranteed between 80.36 V and 83.64 V at 250 mA test current and 25°C ambient, meeting tight regulation requirements for precision reference applications.
Is JAN1N4132C-1 RoHS compliant?
No, JAN1N4132C-1 is not RoHS compliant. The "e3" RoHS designation applies only to commercial-grade versions (e.g., 1N4132C-1e3); JAN-level parts like JAN1N4132C-1 use traditional tin-lead plating per MIL-STD-750 and are exempt from RoHS restrictions due to their military qualification status.
What is the maximum reverse leakage current for JAN1N4132C-1?
JAN1N4132C-1 has a maximum reverse leakage current (IR) of 0.01 µA at VR = 65.6 V (80% of VZ). This ultra-low leakage ensures minimal error contribution in high-impedance bias networks and preserves accuracy in battery-powered or low-power instrumentation circuits.
Can JAN1N4132C-1 be used in surface-mount designs?
No, JAN1N4132C-1 uses a DO-35 axial-leaded glass package and is not suitable for surface-mount assembly. For SMT equivalents, consider the 1N4132US-1 in DO-213AA package - same electrical specs but different mechanical form factor and qualification level.
What is the thermal resistance junction-to-lead for JAN1N4132C-1?
JAN1N4132C-1 has a thermal resistance junction-to-lead (RθJL) of 250°C/W when measured with 3/8 inch (10 mm) lead length from body. This value guides heatsinking design for continuous operation near rated 500 mW dissipation, especially in confined chassis or high-temperature ambient environments.
