Product details
Overview
JANS1N4132C-1/TR from Microsemi is a 82 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JANS level per MIL-PRF-19500/435 for high-reliability aerospace and defense applications, with 40 µV/√Hz max noise density at 25 °C and dynamic impedance of 800 Ω at 250 mA test current.
For engineers reviewing the JANS1N4132C-1/TR datasheet, JANS1N4132C-1/TR pinout, JANS1N4132C-1/TR application, or JANS1N4132C-1/TR equivalent, key selection criteria include Zener voltage tolerance (2%), radiation hardness, thermal resistance (250 °C/W junction-to-lead), low noise performance, and military-grade qualification level.
Technical Context
This device operates as a precision voltage reference in reverse-biased breakdown mode, with regulation stable across -65 °C to +175 °C junction temperature range and linear power derating from 500 mW at 25 °C to zero at 175 °C. Its metallurgical bond construction ensures mechanical robustness under thermal cycling and shock.
The JANS1N4132C-1/TR exhibits a positive temperature coefficient of +0.100 %/°C and maintains ≤0.01 µA reverse leakage at 65.6 V, supporting low-drift biasing in analog signal chains and power supply feedback loops where long-term stability and ESD immunity (per MIL-STD-750 method 1020) are critical.

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% spec but in DO-213AA surface-mount package; no axial leads | Requires PCB rework for SMT-only assembly; lacks JANS qualification (JANTXV max) | Select when board space is constrained and military qualification below JANS is acceptable |
| JANS1N4132D-1/TR | Identical construction and qualification, but 1% Zener tolerance instead of 2% | Higher cost and longer lead time; justified only where tighter regulation is required | Select only if system-level voltage accuracy demands <±0.82 V deviation at temperature extremes |
Compared with JANS1N4132C-1/TR, the 1N4132US-1 trades axial-mount flexibility and JANS reliability for SMT compatibility, while JANS1N4132D-1/TR delivers improved tolerance at the cost of availability and price-neither offers pin-compatible replacement without layout or qualification reassessment.

FAQ
What is the Zener voltage tolerance of JANS1N4132C-1/TR?
JANS1N4132C-1/TR has a nominal Zener voltage of 82 V with a tolerance of ±2%, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is guaranteed across the full operating temperature range of -65 °C to +175 °C and verified during JANS-level screening per MIL-PRF-19500/435.
Is JANS1N4132C-1/TR suitable for space applications?
Yes, JANS1N4132C-1/TR is qualified to JANS level per MIL-PRF-19500/435 and inherently radiation hard per Microsemi MicroNote 050, making it suitable for low-earth orbit and deep-space missions where total ionizing dose (TID) and single-event effects (SEE) resilience are required.
What is the maximum reverse leakage current for JANS1N4132C-1/TR?
JANS1N4132C-1/TR specifies a maximum reverse leakage current (IR) of 0.01 µA at 65.6 V (80% of VZ). This ultra-low leakage is confirmed during JANS-level testing and supports use in high-impedance bias networks and precision current-sensing circuits.
Does JANS1N4132C-1/TR have RoHS-compliant termination?
No-JANS1N4132C-1/TR uses traditional tin-lead plating per MIL-STD-750 method 2026, consistent with JANS qualification requirements. RoHS-compliant (e3) versions are available only on commercial-grade variants (e.g., 1N4132C-1e3), not JANS-level parts.
What is the thermal resistance junction-to-lead for JANS1N4132C-1/TR?
JANS1N4132C-1/TR has a thermal resistance of 250 °C/W junction-to-lead when measured with 3/8″ (10 mm) lead length from body, enabling reliable 500 mW operation in through-hole mounted configurations with adequate copper pour and airflow.
