Product details
Overview
1N4132-1 from Microsemi is a 500 mW, 82 V metallurgically bonded glass Zener diode in DO-35 (DO-204AH) package, qualified to JANS level per MIL-PRF-19500/435. It delivers ±5% Zener voltage tolerance at 250 mA test current, exhibits 800 Ω dynamic impedance, and supports stable regulation across -65°C to +175°C junction temperature for high-reliability voltage reference applications in aerospace power supplies.
For engineers reviewing the 1N4132-1 datasheet, 1N4132-1 pinout, 1N4132-1 application, or 1N4132-1 equivalent, this page provides verified Zener voltage, thermal resistance, noise density, temperature coefficient, and military qualification details critical for radiation-hardened analog reference design and precision biasing in harsh-environment systems.
Technical Context
This device operates as a reverse-biased voltage regulator with a nominal Zener voltage of 82.0 V at IZT = 250 mA and αVZ = +0.100 %/°C. Its metallurgical bond construction ensures low noise density (1 µV/√Hz typical), minimal capacitance, and inherent radiation hardness per MicroNote 050.
The 1N4132-1 is rated for 0.5 W average power dissipation with linear derating from 25°C ambient to zero at 175°C, and features RθJA = 300°C/W on FR4 board - enabling use in thermally constrained mil-aero circuits where stable reference voltage under wide temperature excursions is mandatory.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 1N4132UR-1 | Same 82 V Zener voltage but in DO-213AA surface-mount package; no axial leads | Required for automated SMT assembly; unsuitable for through-hole prototyping or manual repair | Select when board space is constrained and reflow compatibility is mandatory |
| 1N4132-1e3 | Identical electrical specs and DO-35 package, but RoHS-compliant matte-tin plating (commercial grade only) | Restricted to non-military commercial programs; not qualified to JANS or JANTXV levels | Select only for non-mil applications requiring lead-free compliance |

FAQ
What is the Zener voltage tolerance of the 1N4132-1?
The 1N4132-1 has a nominal Zener voltage of 82.0 V with a standard tolerance of ±5% at 250 mA test current, as specified in the Electrical Characteristics table on page 3 of T4-LDS-0245-2 Rev. 1. This tolerance applies to all units unless marked with a tighter C (±2%) or D (±1%) suffix, which the 1N4132-1 does not carry.
Is the 1N4132-1 qualified for space applications?
Yes, the 1N4132-1 is qualified to JANS level per MIL-PRF-19500/435, the highest military reliability grade, and exhibits inherent radiation hardness per Microsemi MicroNote 050 - making it suitable for low-earth orbit and deep-space missions where total ionizing dose (TID) resistance is required.
What is the maximum power dissipation of the 1N4132-1 at 25°C?
The 1N4132-1 has a rated average power dissipation of 0.5 W at TC = +25°C. This value linearly derates to zero at +175°C junction temperature, with a thermal resistance of RθJA = 300°C/W on FR4 board per the Maximum Ratings table on page 1 of the datasheet.
Does the 1N4132-1 have low noise characteristics?
Yes, the 1N4132-1 exhibits a noise density of 1 µV/√Hz at its 82 V Zener voltage and 250 mA test current, as confirmed in the Electrical Characteristics table. This low noise performance is enabled by metallurgical bonding and makes the 1N4132-1 suitable for precision analog reference circuits.
What package type is used for the 1N4132-1?
The 1N4132-1 uses the DO-35 (also designated DO-204AH) axial-leaded, hermetically sealed glass package. Dimensions and mechanical specifications are provided on page 5 of T4-LDS-0245-2 Rev. 1, confirming a body diameter of 1.42–2.29 mm and overall length of 3.56–5.08 mm.
