Product details
Overview
JAN1N4131C-1/TR from Microsemi is a 75 V, 2% tolerance, 500 mW metallurgically bonded glass Zener diode in DO-35 package, qualified to JAN reliability level per MIL-PRF-19500/435, used for precision voltage regulation in military and aerospace power supply reference circuits.
For engineers reviewing the JAN1N4131C-1/TR datasheet, JAN1N4131C-1/TR pinout, JAN1N4131C-1/TR application, or JAN1N4131C-1/TR equivalent, key selection criteria include Zener voltage tolerance (±2%), noise density (1 µV/√Hz), temperature coefficient (+0.100 %/°C), and JANS-qualified thermal stability up to +175 °C.
Technical Context
This Zener diode operates in reverse breakdown with cathode-banded polarity, delivering stable 75 V regulation at 250 mA test current (IZT). Its metallurgical bond construction ensures low noise and high reliability under thermal cycling and radiation exposure.
It exhibits 700 Ω dynamic impedance (ZZT) at IZT, 0.01 µA maximum reverse leakage (IR) at VR = 60 V, and linear power derating from 500 mW at 25 °C to zero at 175 °C - critical for high-temperature avionics and satellite subsystems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Zener voltage regulation applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| JANTXV1N4131C-1/TR | Higher screening level (JANTXV vs JAN); tighter parametric testing; same VZ, ZZT, ND | Required for systems demanding extended burn-in and radiation lot acceptance testing | Select when full MIL-PRF-19500/435 JANTXV compliance is mandated by program spec |
| 1N4131C-1/TR | Commercial-grade version; RoHS-compliant plating; no MIL qualification or screening | Suitable only for non-military industrial prototypes or cost-sensitive test fixtures | Select only for bench validation where radiation hardness and long-term reliability are not required |
Compared with JANTXV1N4131C-1/TR, the JAN1N4131C-1/TR offers verified JAN-level screening at lower cost and shorter lead time, while 1N4131C-1/TR lacks military qualification entirely - making JAN1N4131C-1/TR the optimal balance of reliability, availability, and program compliance for Tier-1 defense subcontractors.

FAQ
What is the Zener voltage tolerance for JAN1N4131C-1/TR?
JAN1N4131C-1/TR has a nominal Zener voltage of 75 V with a ±2% tolerance, as indicated by the "C" suffix in the part number per Microsemi's nomenclature. This tolerance is guaranteed across the full operating temperature range (-65 to +175 °C) under specified test conditions (IZT = 250 mA, TC = 25 °C), and is validated during JAN-level screening.
Is JAN1N4131C-1/TR RoHS compliant?
No, JAN1N4131C-1/TR is not RoHS compliant. The "e3" RoHS designation appears only on commercial-grade variants (e.g., 1N4131C-1e3/TR); JAN-level parts retain traditional tin-lead plating to meet MIL-STD-750 solderability requirements and avoid reliability risks associated with pure matte-tin finishes in high-reliability applications.
What does the "TR" suffix mean in JAN1N4131C-1/TR?
The "TR" suffix indicates tape-and-reel packaging per EIA-296 standard, enabling automated placement in high-volume manufacturing. JAN1N4131C-1/TR is supplied in reels with standardized orientation (cathode band facing consistent direction), moisture-sensitive level (MSL) 1 rating, and full lot traceability - essential for aerospace and defense assembly lines.
How is the temperature coefficient of JAN1N4131C-1/TR defined and applied?
JAN1N4131C-1/TR has a temperature coefficient of +0.100 %/°C, meaning its Zener voltage increases by 0.075 V per 10 °C rise above 25 °C. This value is measured per MIL-PRF-19500/435 test methods and is used in circuit design to predict VZ drift across operational temperature extremes - critical for closed-loop regulation in avionics and satellite systems.
Can JAN1N4131C-1/TR be used in surface-mount designs?
No, JAN1N4131C-1/TR uses the axial-leaded DO-35 (DO-204AH) through-hole package. Surface-mount equivalents exist (e.g., 1N4131CUR-1/TR in DO-213AA), but they are distinct part numbers with different qualification levels, thermal characteristics, and mechanical mounting requirements - JAN1N4131C-1/TR must be mounted in axial-leaded PCB footprints.
